The analysis of the 10 FA measures (set-1) as predictors of the 4 neuropsychological task performances (set-2) as criterion measures yielded four dimensions with Rc of 0.72, 0.43, 0.37, and 0.17, respectively. The full model was statistically significant [Wilks’s λ=0.32 criterion, F(40,176.28)=1.53, p<0.034] and explained about 68% of the variance shared between the variable sets. Given the Rc2 effects for each dimension (0.52, 0.19, 0.14, and 0.03), only Dimension one was considered noteworthy in the context of this study (52% of shared variance). The Rs showed that all four neuropsychological performance scores contributed to the synthetic criterion variable (set-2), whereas FA in left thalamus (GM03), left frontal white matter (WM01), left superior longitudinal fasciculus, (WM05), left splenium of corpus callosum (WM08), and left anterior corona radiata (WM09) were main contributors to the predictor synthetic variable (set-1). The respective Rs2 for both criterion and predictor variables supported these conclusions and are highlighted in bold (Table 5). The Rs of visuospatial memory performance scores were positively related to each other and negatively related to lower problem-solving ability. Interestingly, as the Rs of
