A nonparametric bootstrap analysis of the indirect effects of testosterone was conducted for each significant cluster (and sub-cluster) identified in a sex-differences ANCOVA of spatial working memory. There were no significant indirect or mediation effects of testosterone. CI = Confidence Interval, R=right, L=left.
