Association between differential neural fear conditioning responses (CS+>CS− contrast) and Youth Psychopathic traits Inventory (YPI) impulsive-irresponsible traits (left; positive association), and callous-unemotional traits (right; negative association). Single dimension regression analysis effects (red), unique effects (green; i.e. corrected for the other psychopathy dimensions in a multiple regression analysis) and their overlap (yellow) are displayed at P<0.001, k⩾10 uncorrected for display purposes, and are overlaid on an anatomical template. CS, conditioned stimuli.
