PURPOSE OF REVIEW: Anhedonia, traditionally defined as a diminished capacity to
experience pleasure, has long been considered a core symptom of schizophrenia.
However, recent research calls into question whether individuals with
schizophrenia are truly anhedonic, suggesting intact subjective and
neurophysiological response to rewarding stimuli in-the-moment. Despite a
presumably intact capacity to experience pleasure, people with schizophrenia
still engage in fewer reward-seeking behaviors. This discrepancy has been
explained as a dissociation between "liking" and "wanting", with dopaminergic and
prefrontal influences on incentive salience leading hedonic responses to not
effectively translate into motivated behavior. In the current review, the
literature on a key aspect of the wanting deficit is reviewed, anticipatory
pleasure. RECENT FINDINGS: Results provide consistent evidence for impairment in
some aspects of anticipatory pleasure (e.g., prospection, associative learning
between reward predictive cues and outcomes), and inconsistent evidence for
others (e.g., anticipatory affect and affective forecasting). SUMMARY: Mechanisms
underlying anticipatory pleasure abnormalities in schizophrenia are discussed and
a new model of anticipatory pleasure deficits is proposed. Findings suggest that
anticipatory pleasure may be a critical component of impairments in wanting that
impact motivated behavior in schizophrenia.
