Brain-behavior correlations and mediation effects. A, Mental calculation scores were correlated with brain activation of right MFG in the AMC group (r = 0.501, p = 0.008) but not for the control group (r = −0.272, p = 0.209). B, Brain activation of right MFG was correlated with VSWM performance in the AMC group (r = 0.522, p = 0.005) but not for the control group (r = −0.137, p = 0.534). C, D, Brain activation of right MFG significantly mediated the relation between arithmetic scores and VSWM performance in the AMC group. All paths are reported as standardized regression coefficients. **p < 0.01, *p < 0.05.
