Substantively, three hypothesis were made: increasing cognitive load will alter positive cooperation, increasing cognitive load will alter neutral cooperation, and increasing cognitive load will alter negative cooperation. In statistical notation, the null hypotheses for these can be written as follows:
Hpositive,0,: Î¼positive cooperation,high cognitive load = Î¼positive cooperation,low cognitive load,
Hneutral,0: Î¼neutral cooperation, high cognitive load = Î¼neutral cooperation, low cognitive load
Hnegative,0: Î¼negativecooperation,high cognitive load = Î¼negative cooperation, low cognitive load.
Because three separate questions are tested using the same sample variation, a Bonferroni adjusted was made. Therefore, results are reported using both .05 and a .017 (Î± = Î± / k = .05 / 3 = .017) levels, and .01 and .0033 ( Î± = Î± / k = .01 / 3 = .0033) levels. Through the experiment, the independent variable (IV) is cognitive load condition, and the dependent variable (DV) is the type of cooperation being examined.
