Student Nature, Introduction: Students as Genetic Organisms

My last series, Learning Evolved, was inspired by the fourth post in Classroom Democracy, “The Evolution of Learning.” I took a two-page reaction paper and turned it into a sixteen page report because I was interested in the nexus between our evolutionary history and educational present. And now this series follows the pattern, turning the rumination of the first part of Learning Evolved, “Darwinism-Cognitivism,” into a survey of the effects of genetics on teaching. Yet it also is inspired by the fourth part of that series, the humble bibliography. I had taken notes on and read many articles that I was not able to fit into the pages of Learning Evolved. Therefore, I went out of my way to write a series with as many previously neglected citations as possible.

Besides this prologue, Student Nature has four parts. The synopses below introduce the readings, but the individual posts should speak for themselves.

  • Part I, The Nature of the Student
    As all people share a common Universal Human Nature, all learners share a common Universal Student Nature. The all-student cognitive apparatus includes such things as the information-processing system (the OODA Loop), social cooperation, and automaticity.
  • Part II, The Natures of Our Students
    No two students are alike, and the particular student natures vary with age, sex, group, and of course individual. Some ideas are genetically harder for some students to grasp than others, while some types of intelligences and classroom behavior are irregularly distributed around the globe. A one-size-fits-all philosophy cannot possibly work.
  • Part III, Nature and Her Consequences
    Old ideas fall away when exposed to genetic scrutiny, and others stand only perilously. Yet if we aren’t critical of our beloved ideas, reality will be. If they are not reinforced and adapted now they will be crushed later.
  • Part IV, Bibliography
    From Academy of Management Review to WITI Women, Alas Poor Darwin to Human Nature Review, the academic and popular literature is scoured to provide the best possible tdaxp series.

As I said once before: To all those who are interested in the intersection between evolution and education: enjoy!

Keep Politics Away from the People

First: My seminar in genetic factors in political behavior, and the Hendricks conference, have been very valuable to me. I have already been able to use concepts and articles in this class in major papers for two others this semester. Eating with the guests, as well as listening to the final roundtable, were eye-opening experiences for me. The way this research crosses old lines is exciting. It feels wonderful to be able to take articles from Science, or Molecular Psychiatry, and combine with them political laboratory experiments to suggest new classroom teaching methods, for example. So much thought and effort has gone into these academic silos. It just feels good to apply them to each other.

Substantively: For instance, in an earlier reaction paper I criticized “identity” and “rationality.” Without going into to much detail, “identity” is how you would describe yourself to yourself in words while “rationality” is having good, explicit reasons for something. I was extremely skeptical of these claims when I learned them last semester, but I was limited in my “good reasons” against them. The best I could do was describe both as the outcome of a power-bargaining game, because what people say and write are goods than can be traded for other goods. I believe that is a solid criticism, and the readers and presentations for this week back me up.

Alvarez et al. look at how subconscious mental processes affect our view of someone’s trustworthiness. This and similar research questions the wisdom of relying on anything that takes cognition, because if we have learned such social interaction so well that it is now automatic (or have been evolved to survive society so well that it is now evoked) then why waist time on a slower and more error-prone conscious-linguistic-rational method?

This is especially true when we consider how easily manipulated we are. Tooby presents a model to show how outrage is an evolutionary adapted mechanism to signal a need for increased group cooperation. Likewise, Wolak & Marcus show us how anger and personality affect political behavior. Meanwhile, Mutz shows us how television camera position varies how much legitimacy we give those who agree with us.

Still, this raises an interesting problem. People are not built to be rational, because the mind has internal mechanisms which are faster and often better than rationality. Yet even these mechanisms can be manipulated by cunning others. And I think the word “cunning” is important here — merely knowing how to manipulate others (and perhaps oneself) into supporting different positions does not mean that the cunning person is rational — only that they have skill in manipulation. What should people in a democracy do when rational decisions and unconscious decisions are both such flawed mechanisms?

To me the answer is obvious, and comes from cognitive psychology. People get better at something the more they do it. A “ten year rule” seems to cover creativity, talent, and expertise in nearly every talent domain. The more you do something, the more you purposefully practice something, the better you get. At the same time, people have an inborn capacity for “learned helplessness,” where people save time for purposeful practice in a domain that matters to them by eschewing domains where they have less skill (and thus, have practiced less). Thus: politics should be left to the experts.

This approach is fully compatible with democracy. Research by the professors in this class have indicated genetic predispositions to democratic norms, including a preference for deliberative justice and an aversion to corruption and “big-man” behavior. In democracies the people will feel when this behavior becomes uncomfortable to them and will be able to throw the crooks out. Absent such social freeriding by politicians, however, it may make more sense for the government to by run by people who actually know what they are doing. For every decision that actually affects people’s well-being in a way they can predict (which, as we have seen, normally involves corruption or big-man behvaior) there are innumerable ones that require a modicum of experience and knowledge, unobtainable from slogans and rallies.

On most issues mass politics is probably the worst of all possible systems, because it combines our inability to think rationally with our genetic predilections for manipulable thought. The government should not be corrupt, should not be ostentatious, and should not have an agenda obnoxious to the people. Beyond that, leave politics to the politicians. Leave it to the experts. And whatever you do, keep it away from the people.

Global Guerrillas as Advocacy Theory

Recently I was puzzled by an online comment. Responding to something Tanguerna wrote:

It is a tragedy when someone refuses to acknowledge that their baby is dead.

John Robb seconded:

Or stillborn like tdaxp’s “secret war.”

To me this is strange. My post on 5GW, or SecretWar, attempt to describe something that I see as actually happening. If my thoughts on soundlessness and formlessness, say, are inaccurate, I would expect them to be that way: wrong from the beginning, not wrong the the day they are born (written?). Likewise, if they are accurate, they were no more “born” of me than any process is born of a discoverer — the researcher outlines what already exists, but does not create anything new.

Then I realized the obvious: Global Guerrillas is an advocacy theory. The reason that “global guerrillas” do not exist is that Robb hasn’t invented them yet. For his theory to be “true” he does not have to match the facts on the ground, but create the facts. Robb outlines his unique perspective on war not to describe something that exists but to create something new. For him, his idea could truly be stillborn if no groups can be convinced if the existence of his “systempunkt” and other ideas. This also explains his use of incoherent definitions. Robb’s theory becomes “true” if it actually happens, not if his words, deeds, &c agree with each other. “Truth” becomes defined by reality, not by our more traditional scales of veracity. This freedom from the demands of logic, allowing him to claim that the instability of grand coalitions is somehow something new, etc.

5GW is Closed Source (and Global Guerillas Theory is Incoherent)

One of the most irrititing components of John Robb’s pseudotheory of “Global Guerrillas” (GG) is his fast-and-loose attention to terminology. Curtis recently pointed out that while once Robb lumped his imaginary GG’s into 4th Generation (or “net-“) War, now he wants it to be part of 5GW (or “secret-“) War. He later qualifies himself by saying terminology just doesn’t matter, and that appears to be the case: in an incoherent pseudotheory like Global Guerrillas, words don’t matter, because there is no inner meaning to express in words.

Consider, for example, Robb’s discussion of “open source warfare” and 5GW.

Earlier on his blog, Robb discussed open source in something similar to its common meaning: publicly available information

# Release early and often. Try new forms of attacks against different types of targets early and often. Don’t wait for a perfect plan.
# Given a large enough pool of co-developers, any difficult problem will be seen as obvious by someone, and solved. Eventually some participant of the bazaar will find a way to disrupt a particularly difficult target. All you need to do is copy the process they used.

but now he defines open source warfare as:

An ability to decentralize beyond the limits of a single group (way beyond cell structures) using new development and coordination methodologies. This new structure doesn’t only radically expand the number of potential participants, it shrinks the group size well below any normal measures of viability. This organizational structure creates a dynamic whereby new entrants can appear anywhere. In London, Madrid, Berlin, and New York.

I addresssd a software development analogy to 5GW more than a year ago, on one of the first blog posts on 5GW:

Prototyping allows for loose, Darwinian networks of projects competing with each other with user-input. For 4GW, this is fantastic. But just as being “fast” is more important than being completely “right” in maneuver war, being secret is more important than being completely “right” in 5GW.

5GW is not open source. 5GW is closed source.

Note how “Open Source Warfare” has gone from a focus on replication of recent, proven, evolving strategies to mere decentralization. (If you disagree, ask what new technique for decentralization could not be found in a list of “new development and coordination methodologies”). The need for this redistribution is obvious, because 5GW relies on secrecy and preventing observations.

5GW is a speculative generation of war and implies new styles of networks. There are important online sources for 5GW on the web, including Coming Anarchy, Dreaming 5th Generation War, Purpleslog, Thomas Barnett, Zen Pundit, and of course tdaxp.

But not from John Robb‘s mythical Global Guerrillas. At least, not yet.

Update: Curtis Gale Weeks talks sense, at D5GW and TPMB. The best part:

I don’t know what Barnett sees, but perhaps ‘stronger’ for these specific non-state actors is relative to the forces of stability. In GG and similar theories, there appears to be an assumption that approx. 99.9% of the world population (or more!) will just sit back and let the forces of chaos reign, that even the kind of devastation possible by a superempowered individual will outweigh any kind of potential response to such devastation. Chaos is assumed to emerge, but order is not.

Barnett’s far too easy on John Robb. GG, in order for it to actually become a reality, has been twisted into a self-sustaining prophesy powered by selective but obstinate ignorance — i.e., by ignoring large realities. If you believe real demons exist, and moreover that they are entirely unstoppable because no real angels exist, you’ll buy into the prophecy being given by Robb.

In a recent comment, Mark of ZenPundit tipped me off to Robert Slavin, an education researcher who emphasizes group goals and individual accountability. Some other tips were read, as well:

The studies that examined the role of task variables indirectly support the counterforces proposition. Making tasks identifiable, difficult, and/or unique (Harkins & Petty, 1982) or altering the nature of the task (Kerr & Brunn, 1983) basically changes the incentive system fro a group member. In general, such actions enhance the intrinsic satisfaction a group member receives from contributing to the group’s public good. This intrinsic satisfaction is, in effect, a special incentive or private good the group member receives for contributing to the group’s public good, and it serves to decrease the likelihood of free riding. (Albanese & van Fleet, 1985, 252)

Besides some other articles which I am required to read, most of this batch of notes deals with free-riding, accountability, and other similar issues. Many of the articles can be found on JSTOR

Nevertheless, it often is true that people acting rationally, try to minimize their costs relative to the benefits they receive. Free-rider theory (Olson, 1965) explains how this tendency operates to affect group formation and individual productivity in groups. (Albanese & van Fleet, 1985, 244)

Stigler states the basic free-rider problem as follows: “In a wide range of situations, individuals will fail to participate in collectively profitable activities in the absence of coercion or individually appropriate inducements (1974, 359). (Albanese & van Fleet, 1985, 244)

Free-rider theory assumes that individuals (1) are the actors in social situations, (2) share homogeneous value systems, similar information, and similar perceptions of reality, and (3) act rationally. Rationality means that an individual has an ordered set of preferences defined by the individual’s selfish interests and when free to do so will choose behaviors efficacious for achieving those preferences. (Albanese & van Fleet, 1985, 244-245)

The distinction between private and public goods is central to free-rider theory (Buchanan & Tullock, 1962; Olson, 1965; Samuelson, 1954). A good is anything tangible or intangible that satisfies an individual’s needs or desires. Goods can be differentiated by their degree of excludability. In a group, a private good is one for which it is feasible or economic to exclude one or more group members… A public good is one for which it is not feasible or economic to exclude one or more group members. (Albanese & van Fleet, 1985, 246)

One way to assure provision of public goods in large groups is through coercion and/or special incentives. Coercion is any form of influence or persuasion that tends to force the provision of public goods by a a group… Special incentives include increased shares in the public good and various individual incentives, such as personal recognition, a bonus, and so on. (Albanese & van Fleet, 1985, 247)

An identifiable task is one for which the output of an individual can be identified with that particular individual. Studies reporting “social loafing” effects used nonidentifiable tasks (Harkins, Latane, & Williams, 1980; Latane, Williams, & Harkins, 1979). Subsequent research by Harkins and Petty (1982) suggests social loafing effects cna be eliminated by making tasks identifiable. However, even when tasks are nonidentifiable, social loafing may not occur if subjects perceive tasks to be difficult or unique (Harkins & Petty, 1982). (Albanese & van Fleet, 1985, 248)

A study by Kerry and Brunn (1983) suggests that the task type affects group members performance. High-ability group members exerted less effort with increasing group size on a conjunctive task, a group task for which the group product is limited by the contribution of the least capable member (Steiner, 1972). Low-ability group members exerted less effort with increasing the group size on a disjunctive task, a task in which the group product is confined to the contribution of the most capable member (Ingham, Levinger, Graves, & Peckham, 1974; Steiner, 1972). (Albanese & van Fleet, 1985, 248)

Orbell and Dawes (1981) refer to the role of a group member who carries free riders as the “sucker role.” When a group member reduces efforts rather than play the sucker role, the effort reduction is referred to as the “sucker effect” (Kerry, 1983). The sucker effect may arise from incorrect attributions abotu the extent of free riding in a group. (Albanese & van Fleet, 1985, 252)

Altruistic motives may reduce the likelihood and degree of free-riding, but they do not eliminate it. (Albanese & van Fleet, 1985, 252)

Social information processing theory (Griffin, 1983; Salancik & Preffer, 1978) suggests that social cues from respected co-workers or supervisors about task characteristics may cause a group member to perceive a task as unique. (Albanese & van Fleet, 1985, 252)

Yandell, Lonnie. (2002) Web-based resources. In S. Davis & W.Buskist (Eds.). The teaching of psychology: Essays in honor of William J. McKeachie and Charles Brewer. Mahwah, NJ: Lawrence Erlbaum Associates, Inc. (pp. 295-305).

Thorndike was among the first to imply that if we were to alter the process of instruction, the outcome would differ. In what we might now see as a prophetic utterance, he asserted that if “by some mechanical ingenuity, a book could be so arranged that only to him who had done what was directed on page one would page two become visible, … much that now requires personal instruction could be managed by print” (Thorndike, 1912, p. 165). (Beins, 2002, 308)

For example, Gaskill (1933) may have been the first teacher to usher in a form of distance learning. He presented two lectures over the radio; they involved what we would probably now call sports psychology. However, radio did not reappear in the literature as a medium of tutelage for 35 years (Snyder, Greer, & Snyder, 1968). Television broadcasts began as the beginning of the 1950s (Barden, 1951), and even teh telephone served as a teaching tool (Cutler, McKeachie, & McNeil, 1958). (Beins, 2002, 310)

“Instead of producing revolution, interactive courseware has produced barely a ripple on the stagnant surface of the instructional program. But the courseware mirage still beckons” (Ehrmann, 2000, pg. 44). (Beins, 2002, 315)

One of the newest approaches, Just in Time Teaching (JiTT), gives a good illustration of how to maximize what the student, teacher, and computer can achieve in combination… Using this approach, instructors pose questions or offer other preparatory assignments that students have to complete and submit within a few hours of the class meeting. The instructor reads the student responses prior to class and uses their ideas to structure class time. (Biens, 2002, 318)

Progressive social reformers hoped to use education to revitalize democracy through the reconstruction fo the elements of individual political responsibility. (Fass, 307)

The science that had the most profound effect on educational practice as psychology, a hybrid calling which was part biology, part philosophy, and in good part linked with the evolving profession of education. (Fass, 307)

What had begun as a way of eliminating the feebleminded, proceeded to a ranking of individuals according to talent, and finally became a means for ordering a hierarchy of groups. (Fass, 309)

Chamberlin reported using classroom games or experiments for teaching purposes as long ago as 1948. (Fels, 1993, 365)

Universities are based on the principle that teaching and research go together. (Fels, 1993, 365)

At the other extreme, a poor lecturer with low ratings on student evaluation questionnaires could pep up a course with these games. (Fels, 1993, 365)

Free riders are those who enjoy the benefits of a public good without contributing to the costs of providing it. Because it is impossible, or highly expensive, to exclude people from the benefits of a public gone once it is produced, consumers have an incentive to free ride” on the contributions of others. The presence of free riders can lead to the underrepresentation of preferences for the public good and, hence, to its underprovision. (Leuthold, 1993, 353)

Rosen (1992, 76) stresses that free ridership is not a fact, but a hypothesis. (Leuthold, 1993, 353)

Asch and Gigliotti (1991, 33) are also concerned that the standard treatment of free riding behavior as “rational” is ethically questionable. They believe that economists often ignore such noneconomic motivation as sense of commitment or morality. Other motivations for voluntary behavior that have been suggested in the literature include “a desire to win prestige, respect, friendship, and other social and psychological objectives” (Olson, 1965, 60) or “a desire to avoid the scorn of others or to receive social acclaim” (Becker, 1974, 1083). Andreoni (1990, 464) identifies the desire for a “warm glow” as a possible influence on behavior. (Leuthold, 1993, 353)

However, when Isaac and Walker (1988) tested the effect of group size on free riding in an experimental setting, they got mixed results, with small groups being more cooperative in some situations but less cooperative in others. (Leuthold, 1993, 354)

Experimental economics can provide interesting and profound insights into many types of economic behavior. Used in the classroom experiments stimulate student interest and involve students actively in the learning process. Involved students tend to be more attentive, have a more positive attitude toward the subject, and have higher self-esteem because they have more control over their own learning. The free rider experiment described here was specifically designed to bring active learning to the large classroom. It could, of course, be conveniently used in the small classroom as well. (Leuthold, 1993, 361-362).

From a motivationalist perspective (e.g., Johnson & Johnson, 1992; Slavin, 1983a, b, 1995), cooperative incentive structures create a situation in which the only way group members can attain their own personal goals is if the group is successful. Therefore, to meet their personal goals, group members must both help their groupmates to do whatever helps the group to succeed, and, perhaps even more importantly, to encourage their groupmates to exert maximum efforts. In other words, rewarding groups based on group performance (or the sum of individual performances) creates an interpersonal reward structure in which group members will give or withhold social reinforcers (e.g., praise, encouragement) in response to groupmates’ task-related efforts (see Slavin, 1983a)… students to encourage goaldirected behaviors among their groupmates (Slavin, 1983a, b; 1995). A substantial literature in the behavior modification tradition has found that group contingencies can be very effective at improving students’ appropriate behaviors and achievement (Hayes, 1976; Litow & Pumroy, 1975). (Slavin, 1996)

The motivationalist critique of traditional classroom organization holds that the competitive grading and informal reward system of the classroom creates peer norms opposing academic efforts (see Coleman, 1961). Since one student’s success decreases the chances that others will succeed, students are likely to express norms that high achievement is for “nerds” or teachers’ pets. Such work restriction norms are familiar in industry, where the “rate buster” is scorned by his or her fellow workers (Vroom, 1969). (Slavin, 1996)

Use of group goals or group rewards enhances the achievement outcomes of cooperative learning if and only if the group rewards are based on the individual learning of all group members (Slavin, 1995). Most often, this means that team scores are computed based on average scores on quizzes which all teammates take individually, without teammate help. (Slavin, 1996)

Comparisons of alternative treatments within the same studies found similar patterns; group goals based on the sum of individual learning performances were necessary to the instructional effectiveness of the cooperative learning models (e.g., Fantuzzo, Polite, & Grayson, 1990; Fantuzzo, Riggio, Connelly, & Dimeff, 1989; Huber, Bogatzki, & Winter, 1982). (Slavin, 1996)

However, motivational theorists hold that students help their groupmates learn at least in part because it is in their own interests to do so. Social cohesion theorists, in contrast, emphasize the idea that students help their groupmates learn because they care about the group. A hallmark of the social cohesion perspective is an emphasis on teambuilding activities in preparation for cooperative learning, and processing or group self-evaluation during and after group activities. Social cohesion theorists tend to downplay or reject the group incentives and individual accountability held by motivationalist researchers to be essential. For example, Cohen (1986, pp. 69-70) states “if the task is challenging and interesting, and if students are sufficiently prepared for skills in group process, students will experience the process of groupwork itself as highly rewarding…never grade or evaluate students on their individual contributions to the group product.” (Slavin, 1996) [this seems crazy — tdaxp]

In general, methods which emphasize teambuilding and group process but do not provide specific group rewards based on the learning of all group members are no more effective than traditional instruction in increasing achievement (Slavin, 1995), although there is evidence that these methods can be effective if group rewards are added to them. (Slavin, 1996)

One widely researched set of cognitive theories is the developmental perspective (e.g., Damon, 1984; Murray, 1982). The fundamental assumption of the developmental perspective on cooperative learning is that interaction among children around appropriate tasks increases their mastery of critical concepts. (Slavin, 1996)

There is a great deal of empirical support for the idea that peer interaction can help non-conservers become conservers. Many studies have shown that when conservers and nonconservers of about the same age work collaboratively on tasks requiring conservation, the nonconservers generally develop and maintain conservation concepts (see Bell, Grossen, and Perret-Clermont, 1985; Murray, 1982; Perret-Clermont, 1980). (Slavin, 1996)

The importance of peers’ operating in one anothers’ proximal zones of development was demonstrated by Kuhn (1972), who found that a small difference in cognitive level between a child and a social model was more conducive to cognitive growth than a larger difference. (Slavin, 1996)

However, Damon (1984, p.337) explicitly rejects the use of “extrinsic incentives as part of the group learning situation,” arguing that “there is no compelling reason to believe that such inducements are an important ingredient in peer learning.” (Slavin, 1996)

As noted earlier, reviewers of the cooperative learning literature have long concluded that cooperative learning has its greatest effects on student learning when groups are recognized or rewarded based on individual learning of their members (Slavin, 1983a, 1983b, 1989, 1992, 1995; Ellis & Fouts, 1993; Newmann & Thompson, 1987; Manning & Lucking, 1991; Davidson, 1985; Mergendoller & Packer, 1989). (Slavin, 1996)

In groups lacking individual accountability, one or two students may do the group’s work, while others engage in “social loafing” (Latane, Williams, & Harkins, 1979). (Slavin, 1996)

A comparison among Learning Together studies (Johnson & Johnson, 1989) also supports the same conclusions. Across eight studies of Learning Together methods in which students were rewarded based on a single worksheet or product, the median effect size was near zero (+.04). However, among four studies that evaluated forms of the program in which students were graded based on the average performance of all group members on individual assessments, three found significantly positive effects. (Slavin, 1996)

Several studies have focused on the question of which students gain the most from cooperative learning. One particularly important question relates to whether cooperative learning is beneficial to students at all levels of prior achievement. It would be possible to argue (see, for example, Allan, 1991; Robinson, 1990) that high achievers could be held back by having to explain material to theirlow-achieving groupmates. However, it would be equally possible to argue that because students who give elaborated explanations typically learn more than those who receive them (Webb, 1992), high achievers should be the students who benefit most from cooperative learning because they give the most frequent elaborated explanations. The evidence from experimental studies that met the inclusion criteria for this review support neither position. A few studies found better outcomes for high achievers than for low and a few found that low achievers gained the most (see Slavin, 1995). Most, however, found equal benefits for high, average, and low achievers in comparison to their counterparts in control groups. (Slavin, 1996)

One category of tasks that may not require group goals and individual accountability is tasks in which it is likely that students will benefit by hearing others thinking aloud. This is the classic Vygotskian paradigm; students in collaborating groups make overt their private speech, giving peers operating at a slightly lower cognitive level on a given task a stepping stone to understanding and incorporating higher-quality solutions in their own private speech (see Bershon, 1992). Tasks of this kind would be ones at a very high level of cognitive complexity but without a well-defined path to a solution or a single correct answer, especially tasks on which there are likely to be differences of opinion. For such tasks, the process of participating in arguments or even of listening to others argue and justify their opinions or solutions may be enough to enhance learning, even if no teaching, explanation, or assessment goes on within the group. Perhaps the best classroom evidence on this type of task is from Johnson and Johnson’s (1979) studies of structured controversy, in which students argue both sides of a controversial issue using a structured method of argumentation. (Slavin, 1996)

As in the case of controversial tasks without single correct answers, there is evidence that adding group rewards to structured dyadic tasks enhances the effects of these strategies. Fantuzzo, Polite, & Grayson (1990) evaluated a dyadic study strategy called Reciprocal Peer Tutoring. A simple pair study format did not increase student arithmetic achievement, but when successful dyads were awarded stickers and classroom privileges, their achievement markedly increased. (Slavin, 1996)

individual learning of all group members, and feel that it is unnecessary and cumbersome to do so. Widespread reluctance to use extrinsic incentives, based in part on a misreading of research on the “undermining” effects of rewards on long-term motivation (Cameron & Pierce, 1994) has contributed to many educators’ reluctance to use group rewards. (Slavin, 1996)

Cooperative learning is one of the greatest success stories in the history of educational innovation. Almost unknown in the mid-1970s, cooperative learning strategies are now so common-place that they are often seen as a standard part of educational practice, not as an innovation. One national survey (Puma, Jones, Rock, & Fernandez, 1993) found that 79 percent of third grade teachers and 62 percent of seventh grade teachers reported making regular, sustained use of cooperative learning strategies. (Slavin, 1999, 74)

Research on teh achievement effects of cooperative learning emphasizes the importance of group goals and individual accountability (e.g., Davidson, 1985; Slavin, 1995). Yet observational studies of teachers using cooperative methods find that most are using informal versions of the model, typically lacking group goals and individual accountability. This “group work” creates the danger that one child can do the work for the whole group, that some children will take the “thinking rolee” in group activities while others take clerical or passive roles, or that some children may be ignored or shut out of the group activitity, especially if they are perceived to be low achievers (see, for example, Cohen, 1994). (Slavin, 1999,74)

The emergence of electronic and tellecommunications technologies is not only changing what we teach but is transforming how we think, write, and communicate. (Taylor, 1996, 134)

While many nineteenth- and twentieth-century philosophers accept Kant’s criticism of the notion of the mind as a blank slate upon which the data of experience are directly imprinted, they remain suspicious of his claims for the universality of our mental apparatus. From Hegel and Nietzsche to Heidegger and Sartre, philosophers insist that systems of knowledge are physcologically, socially, historically, and culturally relative. While the mind might be preprogrammed, it is not necessarily hardwired. (Taylor, 1996, 135-136)

Whlie personal and cultural differences can, of course, be enriching, they can also generate conflict. (Taylor, 1996, 137)

One of the most common uses of teleconferencing by universities is for distance learning in which communication tends to be one-way and non-interactive. It is obvious that in this kind of extended classroom or lecture hall, contact between teacher and student is difficult if not impossible. (Taylor, 1996, 139-140)

In addition to increasing contact among seminar participants, the electronci environment influenced the teacher-student relation in another important way. Students were much more willing to take the lead in discussions than in any other class I have taught. While the initial impulse to contribute might have been the result of the desire to see themselves on screen, students quickly overcame their exhibitionist impulses and became serious participants in a sustained dialogue. (Taylor, 1996, 140)

Not only did they [graduate students] devise effective laboratory sessions adn write clear procedures and instructions; they also repeated the gesture of uniting theory and practice or form and content by creating a hypertextual multimedia lab manual. (Taylor, 1996, 143)

Having given by research asssistants the opportunity to teach what they had designed, I elected not to attend any of the laboratory sessions… I was beginning to suspect that these technologies create new possibilities for nonhierarchical relationships in which the line separating students and teacherse becomes obscure. (Taylor, 1996, 143)

More faculty are choosing to integrate Web resources into their teaching, and many more teachers are beging encouraged to do so. (Yandell, 2002, 296)

Brown (2000) sugested three aditional positive aspects of the Web. He pointed out that the Web is a “two way push and pull” media (p. 12)… He also observed that the Web is the “first media that honors the notion of multiple intelligences — abstract, textual, visual, musical, social, and kinesthitic… He also suggested that the Web has the distinct advantage of being able to “leverage the small effort sof hte many with the large efforts of the few” (Yandell, 2002, 303)

Blogospheric Reaction to tdaxp’s Psychology kick

As I look at my blog’s front page, I’m struck that every post is “psychologically,” and filed either under Child Psychology, Genetic Polics. Hmm…

Whatever the deeper meaning of that, my two most recent series — Classroom Democracy and Learning Evolved — have received some very kind and insightful comments from fellow bloggers. Among others:

  • Education Wonk kindly liked the parliamentary democracy angle enough to include me on Carnival of Education LXXXVIII.
  • Christian Soldiers finds a lot to like from his experience teaching computer science
  • Blunt Object looks at applying evolutionary educational psychology on yourself
  • ZenPundit gives props to Learning Evolved, Introduction through Part II, though quietly avoids referencing Part III or the original Classroom Democracy series. This raises the question: is Mark a commie spy?
  • Lastly, Edgewise is interested in other recent psychology posts.

    Now if I could just follow Curtis’ suggestion and tie this into 5GW…. Hmmm…

    Notes too late for "Learning Evolved"

    One valuable part about having a blog, besides the invaluable community of critics & fans, is that it helps me write. For some reason posting notes (even notes that are universally ignored and rather vertical-domain-specific) in a semi-public place gives me more motivation to make sure that I am reading the articles and papers carefully. Likewise, using live search from any computer, I am able to quickly search through notes in any class. I wrote Learning Evolved this way, essentially compiling it together from notes I had already taken from this site.

    This post’s notes are over a whole-bunch of way amazing articles, including one that I pointed Curtis to in reference to polyblogic 5GW discussion. Several of the articles are from UNL’s recent Hendricks Forum on genetics in the social sciences.

    Perhaps the most interesting is from a Ph.D, a future J.D, and a Marine, Empathy and Collective Action in the Prisoner’s Dilemma:

    John A. Sautter graduated cum laude from New York University, received his M.A. in History from the University of Nebraska at Omaha and his Ph.D. in political science from the University of Nebraska at Lincoln. He currently attends Vermont Law School in South Royalton, VT and is a Lieutenant in the United States Marine Corps. (Sautter 2)

    The Lt. Dr. should submit his work, which has obvious military implications, to the Small Wars Journal. Unless, of course, he is going after a bigger publisher.

    Anyway, this post is over the following articles:

    The challenge faced by measurement specialists is that of devising valid and reliable standardized measures of writing skills. An information-processing approach to the assessment of writing ability suggests a way of meeting this challenge. (Benton & Kiewra, 1986, 378)

    Good writers outperformed poor writers on these tests in both high school and college samples, when reading comprehension, reading speed, general knowledge, verbal ability, and achievement were controlled (Benton et al.). Such findings support models of writing that acknowledge the role of complex organizational skills in writing (Collins & Gentner, 1980; Hayes & Flower, 1980), and speak to the relevance of the information-processing approach to writing assessment. (Benton & Kiewra, 1986, 378)

    Lectures are as effective as other methods for teaching information, but not more effective. Forty studies suggested that unsupervised reading is better than lecturing… Lectures are quite ineffective for stimulating higher order thinking…Lectures cannot be relied on to inspire, or to change students’ attitudes favorably… Students like really good lectures, but as a rule prefer well conducted group work (Biggs 1999 98)

    Sustained and unchanging low-level activity lowers concentration. Sitting listening to a lecture is such an activity. Yet it requires concentrated effort to follow lecture content. (Biggs 1999 99)

    The attention span of students under these [lecture] conditions can be sustained for about 10 to 15 minutes, after which learning drops off rapidly… A short rest period, or simply a change in activity, after about 15 minutes leads to a restoration of performance almost to the original level… A brief period of consolidation after prolonged learning greatly enhances retention. Getting students to review at the end of the lecture what has been learned leads to much better and more lasting retention than simply finishing and dismissing the students.” (Biggs 1999 100)

    But the basic point remains: do not talk longer than 15 or 20 minutes without a pause, unless you are certain you still have their attention. When you do pause, get the students to change their activity. (Biggs 1999 100-101)

    Think of the large-class situation as a plenary session rather than as a ‘lecture.’ This carries the strong suggestion that there are other ways of using the time than listening to the chair endlessly talking. (Biggs 1999 102)

    Large classes need much more meticulous preparation than small classes. The larger the class, the slower things get done. A spur of the moment change of direction, perhaps in response to a student question, highly desirable and manageable within a group of 30, becomes perilous with 200. (Biggs 1999 103)

    You should make the purposes of each session clearly explicit well in advance. (Biggs 1999 103)

    Notes, handouts, overhead transparencies etc need to be organized before class, ready to be used. (Biggs 1999 103)

    David and McLeod suggest playing lively music to accompany discussion; when it stops, it’s back to the lecturer. (Biggs 1999 104)

    The structure of the lecture is ideally a reflection of the structure of the topics or content being taught. Brown and Atkins (1988) refer to several lecture structures:
    Classical, where the lecture addresses several broad areas…
    Problem-centered: a problem is presented and alternative solutions are suggested…
    Comparative: two or more theories, views, perspectives, etc. are offered and compared. Students need to know the different theories or positions first.
    Thesis: a position is taken and then supported with evidence, argument, hypothesis.
    Whatever the structure, explain it specifically on an overhead or handout. (Biggs 1999 105)

    Stand in front of the lectern, not behind it, which also means don’t read from your notes. Walk about, up and down the aisles if feasible. Get students to leave a few rows empty, so you can move along them. Such plyos give the impression of accessibility, not distance. Stand still, however, when delivering important points. (Biggs 1999 106)

    Partners could be matched by the teacher: alphabetically, or on the basis of the way students complement each other… Alternatively, studnets could choose their own partners, and that probably is the best way. (Biggs 1999 110)

    There is no best method of teaching, ‘but the second best is students teaching other students’ (McKeachie et al 1986:63).(Biggs 1999 110)

    The most prolific resource in large classes is the students themselves, and using them appropriately engages a different set of verbs that address a range of objectives scarcely touched by teacher-directed TLAs (Biggs 1999 117)

    This paper proposes a simple neural model of racial attitude formation that makes an important distinction between socially shared and idiosyncratic racial attitudes. Socially shared attitudes reflect evaluations that are culturally transmitted and may not necessarily represent an individual’s personal views. In contrast, idiosyncratic attitudes represent a sense of interpersonal ‘chemistry’ that may be at odds with dominant social norms. (Craemer, 2006, 2)

    The main difference is that implicit attitudes tend to reflect attitudes that have been rehearsed for a longer period of time and have become automatic. Such automatic responses require no conscious thought while newer attitudes require conscious effort. According (Craemer, 2006, 3)

    The model further assumes that both types of sensory perception, internal as well as external, are subjected to a process of Hebbian learning (Donald O. Hebb 1949), whereby repeated rehearsal leads to automaticity. This process is equivalent to the rehearsal process described in Wilson’s et al. (2000) dual attitude model and its neural basis will be described in greater detail in section 2.2. Finally, on the inter-personal level, the model of racial norms evolution is inspired by Motoo Kimura’s (1983) theory of neutral evolution. (Craemer, 2006, 4-5)

    Idiosyncratic perceptions of internal body states can be expressed in a communicable format with probability p(idiosyncratic). This probability depends on the level of difficulty translating internal body sensations into a communicable format2. It may be easier, for example, to express the internal body state of ‘feeling hungry’ than the complex sensation of feeling a ‘sense of chemistry’ with a complete stranger. (Craemer, 2006, 5-6)

    The principle of Hebbian learning suggests that both types of racial attitudes discussed in section 2.1 – idiosyncratic as well as socially shared – should become automatic after frequent activation (rehearsal). Thus, both types of racial attitudes should be detectable on the unconscious (implicit) level outside of an individual’s conscious control. This leads to a two-by-two classification scheme of racial attitudes distinguishing (1) implicit idiosyncratic attitudes, (2) implicit socially shared attitudes, (3) explicit idiosyncratic attitudes, and (4) explicit socially shared attitudes. (Craemer, 2006, 7-8)

    Nonetheless, a process invariably occurs by which one out of any number of equal alternatives eventually emerges as a socially dominant majority attitude. This process, referred to in biological theory as ‘random drift,’ has been mathematically analyzed by Motoo Kimura (1983) in his theory of neutral evolution. (Craemer, 2006, 8-9)

    Since this evolutionary model is new to the social sciences, a brief description of its biological origin is in place. It was developed by Kimura (1983) to explain evolutionary phenomena that cannot be explained by the Darwinian principle of natural selection. It became necessary when molecular genetics in the late 1960s, to their own surprise, encountered unequal distributions of selectively neutral synonymous alleles. Synonymous alleles are different DNA-sequences, that code for the same protein. Since an organism’s selective advantage relies on the proteins it is composed of, these synonymous DNA-sequences are indistinguishable from one another by natural selection. This puzzle was solved by the strange dynamic of the Neutral Theory of Evolution that demonstrates how a purely random process will inevitably lead to distinct patterns in which one neutral alternative will dominate and eventually replace other equal alternatives. (Craemer, 2006, 9)

    Interestingly, the use of random evolution models in political science precedes Kimura’s neutral theory. In 1968 William N. McPhee (1968) proposed a “Campaign Simulator” (p. 169) based on similar ideas and his colleagues Jack Ferguson and Robert B. Smith applied a related model to voting behavior. (Craemer, 2006, 9)

    Interestingly, on a personal level Thurmond appears to have acknowledged his African American daughter at the same time he publicly uninvited Virgin Island Governor Hastie with the following racist statement: “Governor Hastie knows that neither he nor any other Negro will ever be a guest at the Governor’s house in Columbia so long as I am Governor” (Thurmond on Oct. 25, 1948 cited in Stroud 2003, emphasis added TC). At the same time he secretly received his African American daughter Essie Mae Washington at the Governor’s Mansion (Stroud 2003). (Craemer, 2006, 11)

    That his first acknowledged fatherhood had been in violation of the very anti-miscegenation laws that Thurmond had so desperately fought to maintain flies in the face of any attempt to explain political behavior rationally. (Craemer, 2006, 11)

    The fact that implicit idiosyncratic feelings of closeness towards African Americans appear to be large and significant predictors of racial policy liberalism supports the construct validity of this implicit idiosyncratic measure. The fact, however, that racial priming measures appear to be unrelated to racial policy liberalism at first blush casts doubt on their validity as a measures of implicit socially shared racial attitudes. (Craemer, 2006, 23)

    A number of studies suggest that non-White participants, especially African Americans, display as much pro-White and anti-Black bias in their implicit word associations as their White American counterparts. (Craemer, 2006, 24)

    White and Asian American participants express significantly more pro-White than pro-Black attitudes, while African Americans express overwhelmingly pro-Black attitudes (all deviations from the neutral zero-point are significant at p<.01). (Craemer, 2006, 25-26) In his Address at the Conclusion of the Selma to Montgomery March on March 25th, 1965 Martin Luther King counter-intentionally invoked ingrained linguistic and racial associations while explicitly criticizing such stereotypes: “How long will prejudice blind the visions of men, darken their understanding, and drive bright-eyed wisdom from her sacred throne?” (King in Carson & Shepard 2001, p. 130, emphasis added TC). The explicit attitudes expressed give voice to the views of the Civil Rights Movement, while the figures of speech invoked implicitly represent ingrained elements of the overall linguistic culture. (Craemer, 2006, 26) The tendency for computational models of social communication processes to produce unanimity as a function of random rather than systematic processes has been noted with puzzlement by some social scientists. Andrzej Nowak et al. (1990), for example, criticize: “the implicit null hypothesis seemingly held by most social psychologists is that group processes, if allowed to work themselves through to their conclusion, would lead to a final distribution of opinion … with zero variance” (Nowak et al. 1990, p. 363). (Craemer, 2006, 34-35) Research on threats that involve the potential for physical harm such as crime, natural disasters, and violent conflicts provide clear evidence that personal threat increases one’s sense of vulnerability and motivates action designed to minimize personal risk (Browne and Hoyt 2000; Ferraro 1996; Sattler et al 2000; Smith and Uchida 1988). (Huddy, Feldman, & Weber, 2006, 1) Studies conducted to date find a clear relationship between national threat and support for national and domestic security policies (Davis and Silver 2004; Huddy et al 2005). (Huddy, Feldman, & Weber, 2006, 1-2) Psychologist Abraham Maslow (1943) placed security just above the satisfaction of basic physiological needs in his hierarchy of human needs (and below love and self-actualization). And political scientist Ronald Inglehart (1997), building on Maslow’s work, viewed the fulfillment of basic economic and security needs as a necessary societal precondition to the pursuit of postmaterialist values which emphasize freedom, self-expression and quality of life. (Huddy, Feldman, & Weber, 2006, 2) Bowlby’s attachment theory (1982/69) is an evolutionary-developmental account of social behavior that posits a need for social proximity to protective others under conditions of threat and danger, implicitly assuming a need to maintain a sense of security under threat. Building on Bowlby’s original insights (1969) on the universality of a human need for attachment as way to deal with insecurity, scholars have theorized about the evolutionary advantage of adult attachment under conditions of threat (Ainsworth, Blehar, Water, and Well, 1978; Mikulincer and Shaver, 2003; Fraley, Brumbaugh, and Marks, 2005; Kirkpatrick, 1998; Tancredy and Fraley, 2006). (Huddy, Feldman, & Weber, 2006, 2-3) As noted by Sroufe and Waters (1977), the goal of attachment behaviors is to reduce anxiety through an established sense of “felt security”. The attachment system emerges in early infancy, particularly in the context of the caregiver-child relationship, and operates as a functional system organizing interpersonal beliefs throughout development (Bowlby, 1969). While the attachment system is universal, operating in all humans and a host of other organisms (e.g., Fraley et al., 2005), individual differences often emerge from variations in attachment histories. (Huddy, Feldman, & Weber, 2006, 3) Once established, attachment styles are relatively constant across the lifespan, suggesting that they serve as a stable individual difference (Fraley, 2002; Ainsworth, 1991) that may be mediated by distinct neural and hormonal reactions to threat. For instance, Kraemer (1992) found that physiological indicators of stress such as norepinephrine varied depending on whether rhesus monkeys were reared in isolation versus with mothers or peers. And humans with an enduring sense of insecurity release higher levels of glucocorticoids in stressful situations than those with a secure attachment (Goldberg, 2000). (Huddy, Feldman, & Weber, 2006, 4) Mikulincer and colleagues (Mikulincer, Florian and Weller 1993) examined the effects of the Gulf War, and Iraqi Scud missile attacks, on Israelis with different attachment styles and found that securely attached individuals perceived lower levels of threat, reported higher levels of self-efficacy, actively sought out social support, and pursued constructive problem solving strategies. (Huddy, Feldman, & Weber, 2006, 4) According to attachment theory, one of the key correlates of a secure attachment is a general willingness to trust other people. (Huddy, Feldman, & Weber, 2006, 13) Overall, it appears that insecure individuals respond to the threat of terrorism with enhanced ingroup attachment as reflected in higher levels of reported patriotism. But outgroup derogation is driven simply by threat. (Huddy, Feldman, & Weber, 2006, 15)
    People frequently misuse word pairs such as fewer and less and that and which. But why is this so? Perhaps it is because the concepts they represent do not have a visual referent. That is, it can be difficult for one to create a mental image of what is meant by the word which. (Igo, Kiewra, & Bruning, 2004)

    Pictures, it seems, can be especially important to word learning. In fact, extensive research indcates that pictures are powerful learning tools that can aid in (a) the resilient recall of discrete information over time… (b) the performacne of procedural tasks, such as first aid… (c) the effectiveness of psychology lectures… (d) the learning of cause and effect relationships regarding lightning formation… and (e) memory for prose (Levin & Lesgold, 1978). Critical to this study, however, is that pictures can make word learning easier and vocabulary instruction better… This is especially true for words that represent concrete concepts. (Igo, Kiewra, & Bruning, 2004)

    Two prominent theories regarding how people process pictures and words are dual coding theory (Paivio, 1991) and Baddeley’s (1999) theory of working memory. Each theory explains the integration of words and pictures differently (Mayer, 2001). The dual coding model postultaes the existence of separate verbal and nonverbal memory channels that combine separate memories to make singular mental models. The Baddeley model describes the existence of working memory subsystems for the simultaneous processing of separate verbal and nonverbal information. (Igo, Kiewra, & Bruning, 2004)

    The hallmark of a complex system is that there are many small parts that interact with each other only in loosely coupled ways, sometimes producing surprising and unexpected results (Casti, 1997;DeAngelis and Gross, 1992;Epstein and Axtell, 1996;Kauffman, 1993). (Johnson 2)

    A sincere organization will simply offer citizens a policy package that reflects its “true” organizational policy, while a more sophisticated organization may offer citizens a policy package that differs from the truth. (Johnson 12)

    Consider a“democratically governed group”(Paul E. Johnson, 1990). The members of the organization exercise self-determination. The current members are asked to create the organization’s policy, and the new group policy is used in the advertising effort to attract new members. The multi-dimensional median is offered as a representation of the outcome of an internal decision-making process. Policy change is expected to occur frequently as people are drawn in and out of the organization. Such organizations might gain members as their policy changes, but they also risk alienating existing members who find the organization’s policy moving away from them. (Johnson 21)

    Recall that the ideal points of the citizens are a multivariate normal “hillside.” As discussed elsewhere (Paul E. Johnson, 1996), policy in democratically governed groups is expected to drift, as new positions are adopted that alienate some existing members but draw in new members. Since group members are, more or less, a random sample of people who would find a given position to be tolerable, then we expect that organizations that are positioned on the edges of the policy space will their policy positions drawn toward the center. In other words, although the members of these organizations do not consciously intend to do so, they tend to be hill climbers. (Johnson 21)

    Learning from text can be difficult because of a reader’s limited processing capacity (Turner & Engle, 1989). Cognitive load theory suggests that some texts and learning environments impose greater information processing demands on working memory than others (Chandler & Sweller, 1999; Sweller, van Merrienboer, & Paas, 1998). Cognitive load may vary because of intrinsic or extraneous demands. Intrinsic-load demands stem from the properties of the tobo-learned information (Sweller, 1994) (McCrudden, Schraw, Hartley, & Kiewra, 2004)

    Overall, research reveals that reducing extraneous cognitive load in one design characteristic improves learning (Mayer, 9 1999; Mayer & Moreno, 2002, 2003). (McCrudden, Schraw, Hartley, & Kiewra, 2004)

    Research has shown that different text presentation formats differently affect extraneous cognitive load. For example, Mayer and Chandler (2001) examined the amount of viewer control on the pace of presentation (e.g., computer-controlled pace or self-paced). The computer-controlled pace imposed a higher load than the self-paced presentation because readers were forced to process information without stopping or looking back to previous information. As predicted, readers in the self paced format outperformed those in the computer-paced format. (McCrudden, Schraw, Hartley, & Kiewra, 2004)

    According to cognitive load theory, the effects of each extraneous variablemake a contribution to total cognitive load. When total cognitive load is withinw orking memory limitations, extraneous load exerts minimal influence on learning. When total cognitive load exceeds working memory limitations, learning suffers. The laod imposed by extraneous variables is addititive (Sweller et al., 1988). Reducing extraneous cognitive load reduces overall cognitive load, which may prevent working memory from being overloaded. (McCrudden, Schraw, Hartley, & Kiewra, 2004)

    The first question was whether extraneous variables affect learning. Text presentation had a clear impact on fact and concept learning. Reading text that is presented sentence-by-sentence, as compared with a whole-text presentation, resulted in less fact and concept learning. In other words, performance was better when the reader could refer to the text presented as a whole. This replicated the work of Dillon (2991), who found that requiring mental integration of offscreen information (which has been viewed previously) with current on-screen informaiton decreased learning compared with whole-text presentations. (McCrudden, Schraw, Hartley, & Kiewra, 2004)

    The second question was whether readers perceive differences in ease of comprehension among the three extraneous variables. Results show that readers perceived greater ease of comprehension for low-load versions of text presentation and text organization. This is concistent with previous research in cognitive load (Sweller, 1999) and text processing (McKoon & Ratcliff, 1990; van den Broek et al., 1995; van Oostendorp, 1994) in which learners reported differences in perceived cognitive load resulting from the manipulation of extraneous load variables. (McCrudden, Schraw, Hartley, & Kiewra, 2004)

    Collectively, these findings are consistent with the cognitive resource sharing model described by Miyake (2001), which states that limited cognitive resources in working memory can be allocated flexibly between storage and processing activities. (McCrudden, Schraw, Hartley, & Kiewra, 2004)

    For example, at least since the Eisenhower administration, the gap between Republican and Democratic citizens’ approval of the president has never been as wide as it has become under George W. Bush (Jacobson 2007). (Mutz 3)

    If citizens remain unaware of any legitimate opposition, then political conflict itself seems petty and unnecessary (see Hibbing and Theiss-Morse 2002). Moreover, if the losing side in any given controversy perceives no legitimate basis for the positions of the winning side, then the losers are unlikely to cooperate in maintaining and perpetuating the rules of the game (see Anderson et al. 2005). (Mutz 4)

    Watching others discuss opposing perspectives on television is qualitatively different from participation in face-to-face discussion, and the evidence on face-to-face deliberation is mixed in what it suggests about its outcomes (see Mendelberg 2002). (Mutz 5)

    Granting legitimacy to those with whom one has significant differences of opinion is a complex and cognitively difficult task. To comprehend the logic and motivation behind views that are not one’s own is an effortful, multi-step process (see Gilbert 1991). (Mutz 6)

    Indeed, those involved in the production of political television routinely argue that lively and passionate debate is a necessary ingredient for a successful television program involving political topics. Anything less is probably too boring to attract the attention of television audiences (see, e.g., Christianson 1986, Bradley et al. 1992, Christianson et al. 1986). (Mutz 7)

    In one study, Storms and Thomas (1977) showed subjects a mock survey supposedly filled out by a person the subject was about to meet. The surveys were rigged to convince each subject that the confederate’s attitudes were either very similar to or highly dissimilar from his or her own, based on random assignment… When the confederate sat abnormally close to the subject, violating the norms for personal space, close physical distance interacted with attitude similarity to intensify attitudes toward the confederate (see also Schiffenbauer & Schiavo 1976; Middlemist, Knowles & Matter 1976). (Mutz 8)

    This pattern of reactions to interpersonal distance has been well documented in the realm of face-to-face interaction. Dissimilarity breeds dislike, and closeness generally intensifies whatever kind of reaction – positive or negative – a person has to another person or object. (Mutz 8)

    Likewise, Reeves and Nass (1996) find that viewers’ levels of attention and recall respond to mediated simulations of interpersonal distance (manipulated through the use of close-ups versus long shots, and through the size and distance of the image from the viewer) in much the same way that they do to interpersonal distance in face-to-face contexts. (Mutz 9)

    The sense of threat experienced by television viewers is not likely to be a cognitive acknowledgment of some real threat; after all, few people would claim they feel imminent danger from a politician on a television screen. Instead, it is a subconscious feeling of threat based on the perception of being physically very close to someone who is disagreeable, and who thus presents an unwelcome invasion of personal space (Persson 1998). (Mutz 10)

    On one hand, some level of arousal is absolutely necessary in order to produce attention to the content of political discourse. The arousal produced by “in your face” political discourse should heighten levels of physiological arousal, and thus enhance attention to content and promote greater awareness of oppositional perspectives. Viewers cannot be expected to learn anything about oppositional perspectives unless they are paying attention. (Mutz 10)

    Recall of arguments was enhanced by the same factors that enhance arousal: incivility and a close-up camera perspective. For awareness of oppositional issue arguments, the interaction of incivility and close-up camera perspective was significant (F=4.36, p<.05). For awareness of arguments on one’s own side, only incivility significantly enhanced recall (F=5.13, p<.05), though the pattern is very similar to the left-hand side of Figure 2. The uncivil, close-up conditions consistently stand out in producing higher levels of recall. (Mutz 20) Levels of civility mattered a great deal to perceptions of the legitimacy of opposition views when subjects viewed the uncivil exchange in one of the close-up conditions. (Mutz 22) In contrast to this rational-essentialist view it has been shown that individuals do “irrationally” cooperate in both a Prisoner’s Dilemma game and in real life scenarios that are parallel to it (Axelrod, 1984; Ridley, 1996; Field, 2004). (Sautter 2) Evolution has cultivated a multitude of personality traits that vary amongst humans. This phenotypic variation allows for selective advantages on the group level (Wilson, 2002). (Sautter 4) Studies of autism, violent behavior and other asocial disorders indicate that genetic inheritance, as well as environmental conditioning, is an important determinant of patterns of behavior (Ebstein, Benjamin, and Belmaker, 2003; Pericak-Vance, 2003). (Sautter 5) Empathy can be defined and interpreted under the auspices of three main sub-characteristics: concern for others, perspective taking (also called theory of mind empathy) and personal distress, or the ability to have emotional reactions to others in need. A study of 800 twin-pairs that compared monozygotic to dizygotic dyads estimated the combined inheritance of these three components of empathy to be estimated at 32% (Davis et al., 1994). (Sautter 5) Indeed, this sort of emotional capacity has been important to researchers looking at what motivates moral and pro-social actions, finding that higher levels of empathy tend to make individuals more likely to be morally outraged or to take action to prevent unjust acts (Davis, 1996; Smith-Lovin, 1995). (Sautter 5) There are three main evolutionary arguments for the development of empathy. First, is the well known theory of kin selection (Hamilton, 1964)… The second evolutionary theory focuses more on the interaction with those who are not genetically related. Reciprocal altruism hypothesizes that the empathetic bonds that develop in friendships or working relationships evolved out of an iterated sequence of encounters where conspecifics mutually benefited from cooperation (Axelrod, 1984)… Finally, the group-selection model of human evolution posits that inter-group conflict promoted the adoption of empathetic characteristics because natural selection would have rewarded those groups that worked together well over groups that would not have contained the frequency of individuals with cooperative dispositions (Sober and Wilson, 1998). (Sautter 6) The Prisoner’s Dilemma has been invoked time and again in explanation of the evolutionary origins of human behavior. It represents in a simplified manner the continual problem of reciprocity, trust and collective action (Rapoport and Chammah, 1965; Axelrod, 1984; Ridley, 1996; Fehr and Schmidt, 1999) that is ever-present in iterated interactions between human beings. This makes the Prisoner’s Dilemma framework ideal for a test of pro-social emotional disposition in an incentive based game because it is simple enough for those first exposed to it in an experimental setting to comprehend, yet theoretically sophisticated so as to allow a rich interpretation of the results.2 (Sautter 7) In contrast to Olson’s more traditional economic view of collective action, Hardin (1982) frames the free-rider problem as really an N-person Prisoner’s Dilemma (PD) game. (Sautter 7) Much in line with the way that evolutionary theorists suggest that reciprocal behavioral situations may have evolved in humans some theorists, including Palfrey and Rosenthal (1983) as well as Axlerod (1984), suggest that if certain conditions are met cooperative behavior is a predictable outcome of the PD. First, individuals need to have a low rate of time-preference, or in other words they should not discount the future too much. The second condition is that the game theoretic scenario needs to be repeated several times. This mitigates the standard oneshot strategy of defection. Similarly, the third condition requires there to be uncertainty among the players about when the game will end. Under rational choice assumptions players will always defect in the final round if information is available on when the game will end. The final condition involves punishment. If each player is capable of punishing other players that defect over the course of the game then an incentive structure is created that discourages defection. Theoretically, these conditions work best when there is no central authority and agents are left to their own to decide whether to defect or cooperate. (Sautter 8) Andreoni and Miller (1993) find that altruists even exist in the finitely repeated PD, where individuals are aware of when the game will end… By separating the two groups Andreoni and Miller are able to show that reputation is not as important to altruistic behavior as it might be thought. Indeed, their findings suggest that people probably have what they refer to as “homemade” altruistic preferences, or in other words, people tend to have individual dispositions making them more likely to cooperate. (Sautter 8-9) Fehr and Schmidt (1999) look at the PD in an entirely different way. Somewhat similar in manner to Hibbing and Alford’s (2002) notion of people as wary cooperators, they see individuals as being inequality averse. People in this conception of the PD have an evolved inclination toward seeing equal distribution of payoffs. Framing becomes the key in this case. If players are more optimistic about the other player’s probability of cooperating then inequality-averse players will cooperate more often than the standard theoretical completely rational agent. They present this idea as a social utility function, where each player calculates their payoff in regard to how that payoff relates to the other player’s payoff, thus making inequality-averse players conditional cooperators. (Sautter 9) This notion of egalitarianism coincides with the way that evolutionary psychology theorizes that individuals have innate preferences for fairness. Absolute outcomes are not as important as relative outcomes. The process of how the game is played in relation to the other player becomes the most important aspect. Both evolutionary theories of multilevel selection and reciprocal altruism reflect this focus on relative outcomes. In the case of collective action, individuals should be disposed toward equal and fair outcomes that reflect an innate desire to achieve what is implicitly best for the group, not for the individual (Fehr and Gachter, 2000). (Sautter 10) Evolutionary pressure equipped humans with emotions in order to guide their decision making in the group context (Bowles and Gintis, 2003). From this perspective it is not rationality per se that a researcher should be investigating, but the emotions that lead to intra-group rationality that are designed to deal with conflict and compromise. (Sautter 10) At the base of this emotional temperament is a pro-social empathetic disposition that varies from individual to individual. As Sober and Wilson (1998) imply throughout their polemic, empathy is the veritable context with in which all choices are made.4 Indeed, McCabe et al. (2001) found that different parts of the brain are used when a player is competing against a computer versus another human. When playing against another human a large part of the pre-frontal cortex becomes activated, while in contrast when playing a computer only a small area in the rear of the brain that is used in mental calculation, like arithmetic, becomes activated. (Sautter 11) Hypothesis I: A more robust empathetic psychological disposition will lead to higher rates of “punishment” or mutual defection in the face of an initial defection by another player. (Sautter 11) Hypothesis II: Empathy will predict more forgiving behavior in a player during a period when the opposing player attempts to re-establish mutual cooperation. (Sautter 11) Students made their decisions simultaneously with their opponent. They were given the impression that they were playing another person when in reality they were playing a computer programmed to either cooperate or defect. (Sautter 12) However, the hypothesis for this experiment is that those with a higher level of empathy will defect at a higher rate than those with lower levels because of their group-oriented leanings. (Sautter 14) The third stage in the experiment is the most interesting part. According to Hibbing and Alford’s (2002) theory of humans as wary cooperators that want to be neither leeches (take advantage of others) nor suckers (to be taken advantage of), when the computer begins cooperating individuals should feel as though they are being leeches on a cooperative person. (Sautter 14) Independent variables used in regression analysis included age, gender, income, population of hometown, race and grade point average. It was felt necessary to control for these differences in socioeconomic status in order to isolate the effects of empathy. As Schieman and Van Gundy (2000) show, empathy is a context specific phenomenon that is particular to one’s socioeconomic status.6 By documenting the relationship between education, age, income and gender over an entire community, they are able to demonstrate that empathy levels are relative to one’s social position. For instance, Shieman and Van Gundy present evidence that empathy tends to decrease with age, but that increases in higher education, income and by being female can mitigate this general trend. If these factors were not taken into account it would lead to a misguided analysis of the role that a particular individual’s relative level of empathy plays in their decisionmaking process. (Sautter 15-16) The experimental results are presented below in a statistical appendix. Two types of regression analysis were used in examining the data. The first consisted of a standard ordinary least squares regression. The second type used was a tobit regression model. Tobit (0,X) estimation models were used because of the truncated nature of each of the dependent variables. This statistical methodology can control for the two different types of theoretical participants in the experiment: those that defect all of the time (or, 0 cooperation) and those that cooperate to varying degrees (or, X cooperation). (Sautter 17) In the ordinary least squares (OLS) regression the first thing one should notice is that the F – statistic, or model fit test, is not significant, meaning that little to none of the variance present in the dependent variable is being explained by the independent predictors. What variance is explained is being predicted by the round one variable, which is significant at p < .01 level. (Sautter 18) Not surprisingly, the round one predictor is a very strong indication that participants would cooperate during the entire experiment. However, in these regressions no other independent predictors, including empathy, were significant. (Sautter 19) The first hypothesis presented was that empathy would be a significant predictor of participants’ defection in the second stage of the experiment. In both the OLS and tobit estimations a participant’s empathetic disposition was a significant predictor of defection in retaliation to the opposing player’s second stage defections. For these two analyses, the null hypothesis can be rejected. Empathy was a factor. (Sautter 20-21) The second hypothesis that an empathetic disposition would lead to higher rates of re-cooperation in the final stage of the experiment was flat out wrong… Truly, empathy was not a facilitator of restoring cooperation after reciprocal trust had been broken. (Sautter 21) This indicates that there is a possible “J-curve” to empathy, or that high levels of empathy can produce either more defection or more cooperation depending on the individual, but that participants with a median level of empathy will converge toward cooperating about 50 percent of the time.9 (Sautter 22) This indicates that there is a possible “J-curve” to empathy, or that high levels of empathy can produce either more defection or more cooperation depending on the individual, but that participants with a median level of empathy will converge toward cooperating about 50 percent of the time.9 (Sautter 24) Finally, an analysis of the possible differences between individuals with high levels of empathy residing in the more cooperative empathy peak and the less cooperative empathy peak was conducted. All possible variables that were gathered from the survey after the experiment were investigated. The size of a participant’s home town and the level of their family income were found to be statistically significant predictors. Figures 7 and 8 show the results of the difference of means test for each variable. Essentially, those individuals with high levels of empathy present in the “more cooperative peak” tended to have been raised in smaller towns and come from families with a relatively lower level of income. (Sautter 24-25) The results of this experiment suggest social conditioning could be very important to the manner in which an empathetic disposition manifests itself in social decision making. Being from a larger urban area during an individual’s childhood would likely diminish the reputation effects of continued social interaction. (Sautter 25) Higher rates of empathy tended to have two contrary effects by either making an individual more likely to defect or more likely to cooperate, but not to converge toward the median level of cooperation as the majority of participants in this experiment. (Sautter 25) Contrary to the hypotheses originally being tested, it is not that empathy has a simple positive linear relationship with a desire for egalitarian outcomes. Rather, an empathetic emotional disposition likely cultivates a sensitivity to social decisions, which depending on an individual’s social conditioning, leads to a more intense display of cooperation and defection. (Sautter 26) For example, when comparing professional historians and high school students, Wineburg (1991) found taht historians read texts from a critical perspective in which they actively questioned and transformed text, whereas high school students interested in history read from a less critical perspective without seriously questioning the legitimacy of text assertions. (Schraw & Bruning, 1996, 290) In analogous research, Dweck and Leggett (1988) found that older students and even adults often have little specific awareness of the theories and models they use to understand the world. (Schraw & Bruning, 1996, 302)

    Learning Evolved, Part III: Coalitionary Education

    Altruistic punishment is another tool to rely on. People will forfeit rewards if it means they can punish free-riders and others who have treated them unfairly (Sanfey et al, 2003, 1755). Give students a meaningful opportunity to punish free-riders in their group, such as being able to deduct a point from another’s students project at a cost to one point to the punishing student. The more free-riders free-ride, the more they will be punished, and such a system will significantly increase contributions from students as a whole (Fehr and Gachter, 2000). The benefits of punishing increases with each cheater deterred from free-riding (Boyd et al, 2003, 3533). This sort of punishment is absolutely critical to group work, because without it the human drive to avoid an unfair deal (Smith, 2006) may cause students to give up rather than labor under unfair conditions. Likewise, the presence of free-riders can increase tension and complaints within a group (Price, 2006, 32). Just as we eschew types of instruction that destroys self-efficacy, and so lessons motivation (Chemers, Hu, and Garcia, 2001, 56), we must view free-riding as serious and organize groups such that students can punish, and thereby eliminate, shirking behavior.

    Another threat to motivation is the outbreak of intergroup peace. That is, if one group believes the other will not try hard, it may not try hard. Worse, this peace can snowball, because cooperation reduction is most common between groups which have made it a habit (Sapolsky, 2004). Fortunately, human competitiveness should minimize the chances of this. All a teacher must do is make sure that student groups perceive a threat from another groups, and the behavior will follow automatically. A “perception of threat makes [some people] more likely to perceive threat-based messages as credible” (Lupia, 2002, 321), and such messages can be facilitated by having public group meetings at the end of class or in other ways. Humans are naturally biased thinkers (Lodge and Taber, 1-2), and teachers should design classes to exploit the natural human bias towards group competition, and against intergroup stasis.

    Of course, there are problems here too. Certain populations are more averse to punishing cheaters than others (Kotulak 2006; Singer et al, 2006), or more be more aggressive than others McDermott 35 2006). Fully a quarter of the population does not punish cheaters in laboratory experiments (Kurzban, DeScioli, and O’Brien, 2006) and these types that do not are stable — they perform the same behavior in experiment after experiment (Smith et al, 2004). Interestingly, it appears to be possible to quickly identify who will act cooperatively and who won’t based on simple games (Kurzban and DeScioli, 2005), which implies teachers can use quick “fun-day” session to know how to group students for maximal group output. Likewise, in general required Classes, students may be sorted by major as certain fields of study attract more cooperative students than others (Guth and Tietz, 1990). This can be done by making sure that enough punishers exist in every group to get the most best effort out of the free-riders (Orbell et al, 2004) — to motivate the unmotivated, in other words. If predictive performance sorting such as standardized test scores (Robbins et al, 2005, 262) GPA (Weissberg and Owen, 2005, 308), and standardized test scores (Robbins, Le, and Lauever, 2005, 411) are accepted as valid , then gameplay and majors should be, as well.

    Throughout series I have argued for an approach in which, while the system is designed by the teachers, much of the everyday work is done by the students. This does not take away old methods, such as having a well defined syllabus (Barker, 2002, 382), but rather complements those methods with new knowledge.. Sometimes the best thing that teachers can do is to sit back and not pretend to know every answer (Roth, 1996, 203), or for that matter to know the best way to motivate in every circumstance. Researchers in other fields have now confirmed this, demonstrating that decentralized reward-and-punishment models do not need an all-seeing governing authority (Orbell et al, 2004, 1). Likewise, complex group assignments will allow students to specialize their tasks to their learning styles (Halonen ,2002). Some types of behavior can be adaptive in one setting but ordinarily disruptive in classrooms (Ding, 2002; Harpending and Cochran, 2002), and by allowing the same sort of specialization we see everywhere else in our society, we can design classrooms to get the best motivation out of everyone while still delivering concrete projects, reports, and other academic goods.
