Follow-up Pearson’s correlation analyses were performed to examine the relationship between the z-transformed PPC and DLPFC correlation coefficients and behavioral performance during the supra-span VWM task. Number of missed responses during the supra-span VWM task was negatively correlated with functional connectivity between the right PPC and left DLPFC [r(40) = −.42, p = .007]. Further examination within groups revealed that FHP youth did not exhibit significant correlations between PPC and DLPFC functional connectivity and behavioral performance measures (ps > .23); however, number of missed responses during the supra-span VWM task was negatively correlated with PPC and DLPFC functional connectivity among FHP youth [r(20) = −.63, p = .002]. Significant correlations were not observed between functional connectivity findings and other measures of behavioral performance, such as accuracy or reaction time.
