Fig. 2: Cross-loadings for each behavioral variable on to the multimodal imaging variate.

A cross-loading exceeding ±0.3 is considered substantial (threshold marked with red line). Cognitive test scores across psychomotor speed, verbal memory, and verbal fluency were associated with the multimodal imaging variate (cross-loadings: RBANS Coding [0.58], RAVLT Delayed [0.43], RAVLT Trial VI [0.42], RAVLT Trial I-V [0.39], Verbal Fluency D [0.37], RAVLT Recognition [0.36], and TMT-A [0.31]). The multimodal imaging variate comprised task activation within the left DLPFC (top right) and right supramarginal gyrus (bottom right).
