55 It is important to consider the constraints that are placed on evaluating emotional experience in patients with focal lesions. For example, left hemisphere damaged patients often have difficulty with language, which may affect their verbal report data. To minimize this problem in the present study, severely aphasic patients would not be used and only verbal report measures with simple language were used. Also, right hemisphere damaged patients often have difficulties with visual attention, neglect, and vigilance. Consequently, adequate attention to the task at hand must be insured among RHD patients. To study emotional experience, it is important to measure all three response systems; verbal report, overt behaviors, and physiological indices. One way to better understand the neuropsychology of emotional experience is to use paradigms which are highly sensitive to emotional responding. The present study focused on an anticipation paradigm (Reiman et al., 1989) designed to investigate verbal report, heart rate, skin conductance, and facial responses associated with emotion. In order to examine the psychophysiology of emotional experience, an "in vivo" situation was used. Using anticipation of "in vivo" aversive and pleasant stimuli, it was easier for patients to interpret the emotional meaning of the situations because they did not have to analyze the affective quality of various perceptual stimuli.
