Fourty right‐handed brain‐damaged subjects (20 left‐ and 20 right‐injured; 8 patients with a visual field defect in each group) were submitted to a matching task of facial expressions under various conditions of photographic clearness. Results indicate that right‐damaged subjects, particularly with a visual field defect, produce the lowest performances, although this defect appears only if the stimuli are not too foggy. Our data on neurological subjects agree thus with the literature on normal subjects indicating that the right brain (of normal subjects) is more involved in visual processing of emotional aspects of a face than the left brain. These facts suggest also that this asymmetry appears only under the everyday life conditions of visual clearness.
