  • A, Clusters are listed which showed significantly (p < 0.05, FDR corrected, cluster size threshold >10 mm2) greater activation to Approaching versus Withdrawing face stimuli, as well as one cluster in the inferior parietal cortex showing greater activation to Withdrawing, compared with Approaching, faces (n = 21). B, Clusters are listed which showed a significantly greater approach bias (Approach > Withdrawal) to face compared to car stimuli (n = 21). No cluster showed a greater approach bias to cars compared with faces. Clusters falling within the predefined anatomical regions-of-interest (DIPS, PMv) are indicated with a and b (a, DIPS; b, PMv). Figs. 2, 3. Note that although the peak activations shown at the bottom are in the right hemisphere only, this is because the FDR threshold was higher for the left than for the right hemisphere (because of overall higher levels of activation in the right (vs the left hemisphere). At a non-FDR corrected threshold (p < 0.0005, cluster size >20 mm2), there is activation for this contrast in both the left (−18, −72, 43; z = 4.5; p = 7 × 10 −6; 88 mm2) and right (11, −53, 57; z = 4.7; p = 3 × 10 −6; 213 mm2) DIPS and left (−52, −3, 28; z = 4.4; p = 1 × 10−5; 97 mm2) and right (54, −1, 24; z = 3.9; p = 8 × 10−5; 47 mm2) PMv.
