For each variable tested, the table displays the descriptive statistics, t values, uncorrected p values, and Bayes factors (BFs), for which values smaller than 0.33 indicates substantial evidence for the null hypothesis. Gender effects were assessed by comparing males and females with an unpaired sample t test, all other variables were assessed using robust linear regressions. Bold font indicates significant differences from the null distribution for p values and substantial evidence for the null hypothesis for bayes factors.
