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 FA measures from WM regions (set-1) were positively related to each other and negatively related to left thalamus, they were also positively related to visuospatial memory performance and negatively related to lower problem-solving ability (set-2). Conversely, signs on FA in left thalamus (set-1) and criterion variables (set-2) indicate that FA in left thalamus was positively related to lower problem-solving ability and negatively related to visuospatial memory performance.
