Adolescent Psychological Development, Part I: Cognitive Development

My reaction to David Moshman’s Adolescent Psychological Development (2005) is of a different sort than my nine-part reaction to Cognitive Development by Flavell, Miller, & Miller. There, I found parts of the chapter that interested me and typically criticized it, sometimes throwing in articles I was already familiar with in the process. The reason for this is that I am not all that interested in child cognitive development. Children start out small and cute and whiny and, unless they are horribly mistreated, seem to end up all right in the end.

The same is not true of adults, and adolescents certainly are adults. Indeed, it’s not clear if adults actually can be all right at all. Moshman nears his conclusion by writing “Objectivity, in this view, is a guiding ideal, not an achievable goal” (46) and much of the chapter is written in the rhetoric of limitation. I agree with this approach. Man is a flawed species, and educational psychologists must embrace those flaws to device a truly human education.

Adolescent Psychological Development (the field and the book) properly centers on two concepts: rationality and rational agency. To the best of my understanding, I agree completely with Moshman’s description of both rationality and rational agency. If I do have a disagreement with Moshman, it is this: the latter is not necessary for the former.

“Rationality, in its oldest, broadest and deepest sense,” Moshman (16) writes, “is a matter of having good reasons for one’s beliefs and actions.” This rationality “consists in large part of appropriately applying and coordinating our various reasoning processes” (25). Clearly agreeing with certain theoriests, Moshman on the same page writes that they “see metacognition, broadly construed, as central to rationality” and concludes two pages later that “The development of rationality, as suggested in the previous section, is in large part the development of metacognition.”

Moshman describes a “rational agent” as “an individual who uses epistemic cognition to engage in reasoning” (25). Epistemic cognition is “knowledge about the fundamental nature and justifiability of knowledge and inference” (27). Therefore, a rational agent is he who uses knowledge about knowledge to determine what is true and what is false, or put another way a rational agent is he who justifies his beliefs with a developed argument.

Rationality is thus executive control over one’s cognition, whereas rational agency is rational control over one’s belief. Rational agency is an extension of rational agency, and might even be considered a domain-specific application of rationality. However, (and here I believe I disagree with Moshman) it should not be assumed that rationality agency, whether engaged in or encouraged in others, is itself rational. Rather, if belief formation is under rational control then one must have good reasons why one must have good reasons, or at least better reasons to rely on good reasons than not to rely on them with respect to belief formation. The literature does not support such a stance.

A first approach to the question, is it rational to rely on rational agency, would be to determine if people who have good reasons for their actions in some domain are better than those who do not. Published articles with titles such as “Thinking too much: introspection can reduce the quality of preferences and decisions” (Wilson & Schooler, 1991) suggest, at least when beliefs involve outcomes that actually matter, there is such a thing as too much thought. A concrete example is an experiment where students were allowed to take a poster for free, but one in condition had to present reasons why they chose the poster they did (Wilson, et al. 1993). This rational agency condition resulted in lower satisfaction than was otherwise the case.

Camerer, Loewenstein, & Prelec (2005) divided cognition into four “quadrants”, with “cognitive” and “affective” as columns and “controlled processes” and “automatic processes” as rows (16). Rational agents, desiring to control their reasoning, would be left with one of only four of these quadrants to work with. Yet there is much to life beyond controlled cognition! Automaticity, the movement of thinking in a domain from controlled via “repeated rehearsals” (Cramer, 2006, 4), has been demonstrating in many fields of thought (Morris, Taber, & Lodge., 2003). The role of automaticity in expertise is beyond argument. However, affect is also important. Affect, or emotions broadly defined, combined both information about a task and a utility assessment of the worth of the task. Better to have access to expertise, information, and utility than to be a mere rational agent. Better to exploit all your cognition than just one quadrant of it.

The goal of this first reaction on Adolescent Psychological Development is to describe rationality and rational agency, and begin the work of separating the two concepts. The next thee sections of the book, “Moral Development,” “Identity Formation,” and “Advanced Psychology Development,” will provide the framework for more in-depth discussion of rationality and the benefits of irrational agency. These reactions will build to a discussion of rational moral personhood, the development of which is the proper goal of education.
