Description: Among others: Test whether thinking aloud participants take more time than subjects of the silent control group (included in the 3 x 2 ANOVA from the main analyses). Investigate how often participants from the condition "Einstellung with critical trials" choose the Einstellung solution in the critical trials and compare these numbers for thinking aloud vs. silent thinking (e.g., chi square, logistic regression). From the coded verbal protocols: identify if subjects of the non-Einstellung control group show the direct solution more often as a first attempt and take less solution attempts than subjects of the Einstellung condition. Control for effects of age (correlation) and sex (t-tests, eventually inclusion as a covariate in ANOVA or dummy regression).
