146 emotional content of the situation. Thus, the subjects' abilities to comprehend the emotional context of these in vivo situations is not confounded with the perceptual problems that are common in patients with RHD. Third, multiple response systems of emotion were examined in the present study. Specifically, skin conductance responding was used because it seems to be sensitive to emotional arousal (Greenwald, et al., 1989). Corrugator and Zygomatic EMG were examined because they have found to be useful indicators of emotional valence (Greenwald, et al., 1989). Additionally, heart rate was examined because it has been found to be useful in the study of anticipation (Lang et al., 1978). By using multiple response systems, the presence of potential differential breakdown, (i.e., dissociation between verbal report and autonomic responding), could be examined following hemispheric stroke. Before discussing the manner by which hemispheric strokes affected emotional experience in this study, the data from the normal subjects is discussed. It is important to present the data on the normal subjects first to insure that the tasks produced data that fits with the current knowledge base regarding the psychophysiology of emotion. The summary of the findings based on the differential responding in the normal subjects is presented below,
