Working memory performance tended to intercorrelate across the four tasks and to be related to performance on the cognitive control Stroop task. Working memory was also related to less impulsivity and to better performance on the BART (reward processing). Cognitive control measures did not correlate with each other and displayed few patterns with other indicators apart from working memory. The two measures of reward processing were not highly related but were inversely related to externalizing and internalizing problems. Reversal learning (reward processing) was also related to less impulsivity.
