Notes: Within each row, means that do not share any superscript differ significantly at p < .05 based on Bonferroni-corrected post hoc tests conducted within each ANOVA, η 2p = partial eta-squared. ANOVA = analysis of variance; BART = Balloon Analogue Risk Task; SD = standard deviation.
*p < .05. **p < .01.
