Experiment 3. TOP LEFT: Group median of behavioral choices from the 50 items in Questionnaire 3.b coinciding with the highest hedonic rating to one of the four mathematical items proposing a different solution in Questionnaire 3.a. This figure pools the right and wrong choices. The chance behavior is higher than 0.25 because the tied ratings, which increased the probability for coincidence, are taken into ccount. Wilcoxon matched pairs sign rank test = 5, P = 0.004. TOP RIGHT: Group median of behavioral choices from the 50 items in Questionnaire 3.b coinciding with the lowest highest hedonic rating to one of the four mathematical items proposing a different solution in Questionnaire 3.a. This figure pools the right and wrong choices. The chance behavior is higher than 0.25 because the tied ratings, which increased the probability for coincidence, are taken into account. Wilcoxon matched pairs sign rank test = 5, P = 0.018. Experiment 3. Proportion of coincidence of highest hedonic rating in Questionnaire 3.a with behavioral choice of wrong solutions in Questionnaire 3.b, plotted against the number of correct choices, i.e. mathematical proficiency. Each dot is the result obtained for a given subject. For the group: Y = 0.011 X = 0.21, F-5.9, r = 0.61, P = 0.035.
