Decreased predictive performance was associated with more stringently thresholded models for the empirical brain-behavior associations. Variance explained, R², for four brain-behavior associations (nBack predicting TC, SST predicting SSRT, nBack predicting SSRT, SST predicting TC) were examined using the PVS_U, PVS_B, thresholded variants of the PVS_B, and min-P. Significant associations were identified for the nBack-TC and SST-SSRT, but not for the nBack-SSRT and SST-TC associations. For the two significant associations, the best prediction performance was achieved by the PVS_B where all vertices where included in the model. Predictive performance decreased as more stringent thresholds were applied. All brain and behavioral variables were preresidualized for age and categorical variables including sex, parent marital status, highest level of parental education, household income, self-reported race and ethnicity, and MRI scanner ID.
