Electrophysiological responses to images ranging in motivational salience: Attentional abnormalities associated with schizophrenia-spectrum disorder risk.

ABSTRACT: Individuals at risk for schizophrenia-spectrum disorders display abnormalities related to motivational salience, or the ability of stimuli to elicit attention due to associations with rewards or punishments. However, the nature of these abnormalities is unclear because most focus on responses to stimuli from broad "pleasant" and "unpleasant" categories and ignore the variation of motivational salience within these categories. In two groups at risk for schizophrenia-spectrum disorders-a Social Anhedonia group and a Psychotic-like Experiences group-and a control group, the current study examined event-related potential components sensitive to motivational salience-the Early Posterior Negativity (EPN), reflecting earlier selective attention, and the Late Positive Potential (LPP), reflecting s
