*SE, standard error; DF, degrees of freedom; t, t-statistic; P, p-value. P values were adjusted for multiple comparisons using a Bonferroni correction. Corrections were applied to each main effect, i.e., for three contrasts. Effect size is Cohen’s d with bootstrap 95% confidence intervals (adjusted for three comparisons using Bonferroni correction).
