Table 2. Within-group contrasts.

Within-groups significant clusters (p (uncorrected) < 0.005, minimum cluster = 10 voxels), in each of the three contrasts examined: own interest – visual baseline, others’ interests – visual baseline, and own interest – others’ interests. Clusters that survived correction using 5000 iterations of a Monte Carlo simulation are shown in BOLD and denoted with an
