Between-group contrast of least vs most socially meaningful condition of happy faces reveals differential activity in the ventral visual system. The low callous trait group showed significantly greater activity relative to the high callous trait group in (A) left fusiform gyrus (p < 0.001; p<0.05 corrected) and (B) left middle temporal gyrus (p < 0.001; p<0.05 corrected), when happy eyes-only was contrasted with happy eyes-removed. Follow-up comparisons revealed that the low callous trait group showed greater activity in these regions when viewing the least socially meaningful condition (happy eyes-only) relative to the most (happy eyes-removed), whereas the high callous trait group showed greater activity in these regions for the most socially meaningful condition relative to the least.
