Description: 3 x 2 ANOVA, between subjects, following the design matrix, for solution time. Main effects for the factor “Einstellung” test the hypothesis of Einstellung effect replications; ANOVA contrasts may test the two experimental groups with Einstellung trials against the baseline control. A potential interaction tests the exploratory question of whether thinking aloud affects the extent of the assumed Einstellung effects. For binary variables like solution success: chi-square contingency tests or logistic dummy regression.
