Pearson correlations are between habituation (2nd half vs. 1st half) in mean activation across each cluster and psychopathology questionnaire (PSWQ, MASQ-AA). Correlations were calculated separately for activation related to negative and neutral words. L, left; R, right; M, medial; SFG, superior frontal gyrus; MFG, middle frontal gyrus; IFG, inferior frontal gyrus; DLPFC, dorsolateral prefrontal cortex; MTG, middle temporal gyrus; ITG, inferior temporal gyrus; dACC, dorsal anterior cingulate cortex; BA, Brodmann's area.
