Table 2. Individual behavioral task performance correlations with subject specific weights on C1-IC2 and C2-IC3.

Examination of individual behavioral metrics for Cohort 1 (top) revealed that the relational processing accuracy, progressive matrices task, and 2-back working memory task were correlated with all four modalities at significant or trend-level p-values. In contrast, the flanker task was significantly correlated with only resting state MRI. Examination of individual behavioral metrics for Cohort 2 (bottom) revealed that the relational processing accuracy and progressive matrices tasks were correlated with all four modalities at significant or trend-level p-values. While less significantly correlated, both 2-back working memory task accuracy and the flanker task correlated at trend-level or significant p-values for a subset of the modalities.
