Judgment of facial expression of emotion in unilateral brain-damaged patients.
Patients with unilateral brain damage and normal controls were asked to give (1) inter-emotion judgment within the photographs of six facial emotions in terms of mutual similarities, and (2) intra-emotion judgment within the hemifacial composite photographs of an emotion in terms of intensity of expression. Right brain-damaged patients could differentiate between the emotion of happiness and all other emotions. Left brain-damaged patients differentiated between aroused-nonaroused emotions. Normal controls differentiated between positive-negative as well as aroused-nonaroused emotions. Left-left facial composites were judged to have expressed more intensely than right-right facial composites or normal/mirror-reversed facial orientations of emotions (except fear) by any group (p >.05).
