Abstract:
Patients with focal brain-damage, right/left hemisphere-damage (RHD/LHD) and anterior/posterior region-damage (ARD/PRD), and normal controls (NC) were asked to match photographs of top-bottom facial parts expressing different emotions, positive (happy, surprise), negative-aroused (fear, anger), negative-nonaroused (sad, disgust). The LHD patients performed significantly worse than the RHD patients, and the ARD patients were significantly worse than the PRD patients, in the perceptual-matching task with affective stimuli. NC subjects performed significantly better than any of the brain damaged sub-groups.
