Note. N = 54; DGM = Donoho-Gasko median; MVE = minimum volume ellipsoid estimator; ACC = anterior cingulate cortex; DLPFC = dorsolateral prefrontal cortex; Underline = the Skipped correlation using MVE differs from the other three robust estimators, which are comparable to the Pearson estimate; Bolded = Confidence interval excludes 0.
