alterations in motivation and/or hedonic responses. It is important for future studies to assess measures that can index anticipatory components of positive emotion. Notably, this dysfunction emerged only in trials following omission of reward for a correctly identified rich stimulus. reward-related dysfunction in psychiatric disorders have grown substantially. In addition, the postauricular and startle blink reflex suggested consummatory processes but were not good measures of anticipatory processes. problems in bladder control, sexual dysfunction. Findings on LPP supported previous findings that show the measure reflects context insensitivity to emotional stimuli. Hedonic adaptation refers to a reduction in the affec- tive intensity of favorable and unfavorable. Results for the postauricular reflex and P3 amplitude to anticipatory emotional stimuli supported the theory of emotional dysfunction that emphasizes the lower levels of positivity in depression. A majority of the psychophysiological tools used supported the low positive emotionality model of depression. In addition, several different hypotheses of emotional dysfunction were evaluated to accurately model deficits in positive emotionality. Five clinical profiles were identified in the literature review (persistent negative symptoms, pregnancy, cognitive dysfunction, addictive comorbidity and. Korsakoff patients who have cholinergic dysfunction) and assessing their. The current study employed several psychophysiological tools, postauricular reflex, startle blink reflex, and event-related potential (ERP) components such as P3 and the late positive potential (LPP), to assess the dissociable components in positive emotion (consummatory and anticipatory processes). Other coping strategies associated with relaxation orientation are instead avoidant in a clear dysfunctional sense, such as mental and behavioral disengagement. Overmier and his students are generally concerned with how hedonic events not. Past studies have emphasized controlling negative affect, but there is an emerging trend in the depression literature to focus on positive emotion. Depression is characterized by low positive emotion and a lack of pleasurable experiences, or anhedonia.
