Correlations between CR factors and cognitive function. CR-COGNITIVE scores were positively correlated with performance on the rapid visual information processing (RVP; r = 0.392, p < 0.001), a measure of sustained attention. CR-SOCIAL scores were inversely correlated with Spatial Working Memory Strategies (r = −0.330, p < 0.001), indicating stronger working memory performance in participants with high scores on this factor. Finally, surprisingly, CR-Exercise factor scores were inversely correlated with the number of correct responses on the PAL (r = −0.251, p < 0.05), a measure of episodic memory, suggesting weaker memory performance in participants with the highest scores on this factor.
