Results from a path analysis testing the indirect effects of 2D:4D ratio on trait aggression through variability in dorsal anterior cingulate cortex gray matter identified in our ROI analyses (see Results 3.2.1, Figure 1) as a function of gender. Values represent standardized parameter estimates with standard errors presented in parentheses after controlling for age. Gray matter reductions in the dACC mediate the indirect effect of 2D:4D ratio on trait aggression in women, but not men. The circles labeled e1 and e2 denote the variance in anterior cingulate gray matter volume and trait aggression scores unaccounted for by the model. *p<0.05, **p<0.005
