Zusammenfassung: | Cortical contributions to human emotional expression are examined with a focus on interhemispheric (right vs. left) and intrahemispheric (anterior vs. posterior) mechanisms. This article reviews behavioral studies of emotional expression in brain-damaged patients with unilateral lesions and in normal adults. Studies involving facial, prosodic, and lexical (verbal) communication channels are reviewed for patients; facial asymmetry studies are reviewed for normal subjects. Data are presented separately for posed and spontaneous conditions and for positive and negative emotions. Findings support right-hemisphere dominance for emotional expression, especially for prosodic and lexical expression in brain-damaged patients and for facial expression in normal subjects. Methodological factors are suggested to account for differences among facial expression studies in brain-damaged patients. The data are discussed in terms of neuropsychological theories of emotion and directions for future research. |
