Note. Data are presented as mean (standard deviation). The significance values are for the F statistic. Cohen’s dis calculated as ($({\overline{\mathrm{x}}}_{\text{Negative}}-{\overline{\mathrm{x}}}_{\text{Positive}})∕{\text{SD}}_{\text{pooled}}$) and represents the effect size (Cohen 1988).

^*n = 153 for SO and VP

^**n = 161 for VP
