Correlation table for Spearman correlation coefficient (p-values in parentheses; significant correlations bolded) for the relationship between task performance in each domain (VOCAB=Vocabulary, SPEED=Perceptual Speed, FLUID=Fluid Reasoning, MEM=Episodic Memory) and each internetwork connection by participant age group (Young Adult or YA; Middle Adulthood or MA, and Older Adult or OA).

Note: CO=Cingulo-Opercular Network, DMN=Default Mode Network, MEM=Memory Network, FP=Fronto-Parietal Network, SAL=Salience Network, DAN=Dorsal Attention Network. Bolded correlation coefficients represent those that are significant at p<.05; correlation coefficients with an asterisk represent those that survive multiple comparison correction.
