Main effects are reported in columns 3–4 and planned contrasts in columns 5–6. Coordinates reported are the points of maximal activation of the contrast human show>no-show (column 5, in italics) and/or main effect of opponent type (human>computer, column 4, in italics) within the same clusters of activation. Note that the VLPFC is the only region that did not have a significant main effect of opponent type, indicating no differences in activation between human and computer runs
L left, R right, TPJ temporoparietal junction, TP temporal pole, FG fusiform gyrus, VLPFC ventrolateral prefrontal cortex, MPFC medial prefrontal cortex, ACC anterior cingulate cortex, S ‘show’ opponent's response, NS ‘no-show’ opponent's response, H human-opponent, C computer-opponent
Maximal activation in both contrasts overlap
