volume (RMeOFV), and right caudal middle frontal volume (RCMiFV) were the main contributors to the predictor synthetic variable (set-1). The respective squared structure coefficients (Rs2) for both criterion and predictor variables supported these conclusions and are highlighted in bold (Table 4). The Rs of visuospatial memory performance scores were positively related to each other and negatively related to lower problem-solving ability (EM_3B) in the criterion variable (set-2). Interestingly, as the Rs of volumetric measures in the predictor variable (set-1) were positively related to each other, they were also positively related to visuospatial memory performance and negatively related to lower problem-solving ability in the criterion variable (set-2).
