62 reward control trials. Additionally, SCR will decrease over trials. 3. Compared to baseline corrugator EMG, corrugator EMG (CEMG) will be elevated during shock anticipation and will remain relatively unchanged during prize and control trials. 4. Compared to baseline zygomatic EMG. zygomatic EMG (ZEMG) will increase during prize anticipation. Additionally, a smaller increase may be revealed during shock anticipation. Also, ZEMG will not change from baseline during control trials. Focal Lesion Patients (RHP and LHP) Predictions for the RHD and LHD patients differ depending on the global right hemisphere emotion model versus the bivalent model. Specific predictions for the right hemisphere emotion model will be first presented and then followed by those from the bivalent model. A) Global Right Hemisphere Emotion Model: According to this view, patients with right hemisphere damage are relatively blunted in their emotional responsivity and experience of emotion. Thus, RHD patients will experience less anxiety and positive feelings during the shock and prize conditions, respectively, relative to the NHD and LHD subjects. In contrast, LHD patients may experience more intense emotional responsivity than NHD subjects. Specific predictions are as follows:
