General Design This study had three main parts. In Part I, we searched for any occipitotemporal areas that might be specialized for face perception by looking within each subject for regions in the ventral (occipitotemporal) pathway that responded significantly more strongly during passive viewing of photographs of faces than photographs of assorted common objects. This comparison served as a scout, allowing us to (1) anatomically localize candidate ‘‘face areas’’within individual subjects,(2) determine which if any regions are activated consistently across subjects, and (3) specify precisely the voxels in each subject’s brain that would be used as that subject’s previously defined region of interest (ROI) for the subsequent tests in Parts II and III. We used a stimulus manipulation with a passive viewing task (rather than a task manipulation on identical stimuli) because the perception of foveally …
