T he mesolimbic dopamine (DA) system is part of the brain’s reward circuitry (see the figure). It controls an individual’s responses to rewards such as food, social interactions, and money, and is therefore an important determinant of motivation. Midbrain DA neurons projecting to the striatum are causally involved in reward-like processes. Less clear is how another apparent target of midbrain D...
The deficits in feeding and drinking that result from 6-hydroxydopamine (6-OHDA) lesions of the mesostriatal dopamine system are often explained using either sensorimotor arousal or anhedonia hypotheses. Sensorimotor arousal hypotheses posit that dopamine systems facilitate the capacity of sensory stimuli to activate any motor output. The anhedonia hypothesis suggests that dopamine systems ampl...
BACKGROUND Anhedonia and amotivation are substantial predictors of poor functional outcomes in people with schizophrenia and often present a formidable barrier to returning to work or building relationships. The Temporal Experience of Pleasure Model proposes constructs which should be considered therapeutic targets for these symptoms in schizophrenia e.g. anticipatory pleasure, memory, executiv...

Subjects identified by Perceptual Aberration-Magical Ideation (Per-Mag) scores (n=97), Social Anhedonia (SocAnh) scores (n=45), and Physical Anhedonia (PhysAnh) scores (n=31) as well as normal controls (n=94), underwent psychophysiological and clinical assessment. This is the first published investigation of pursuit system functioning in three groups of questionnaire-identified at-risk individu...
Assessment of Score Dependability of the Wisconsin Schizotypy Scales Using Generalizability Analysis
To investigate the reliability of the Wisconsin Schizotypy Scales, this study applied generalizability analysis with two college student samples who completed the scales at two time points. The results indicated that the Revised Social Anhedonia Scale had acceptable levels of score dependability, but that the score dependability for the other scales (the Physical Anhedonia Scale, the Perceptual...
