Total trials and errors taken during each reversal for Object Pair 2 testing. Repeated measures ANOVA revealed an overall effect of reversal but not treatment [F(3,18) = 4.74, p=.0.01], pairwise comparisons with Bonferroni corrections show that fewer errors were made during the 3^rd reversal compared to the 1^st (p < 0.006).
