Note. t = t-value for two-tailed, independent samples t-test; + p < .10; g = Hedges’ g effect size value with bolded values indicative of moderate to strong effect size (g > .40);

Levene’s test for equality of variances indicated unequal variances (ps < .05), therefore t-test conducted with adjusted degrees of freedom.
