This study summarizes the current knowledge of behavioral and functional neuroimaging in salience, prediction error, and reward. Despite being specific processes, they are integral to decision making and cognition more generally. The dysfunctions in salience and reward processing may be primarily centered in the subcortex during the earliest stages of psychosis, with cortical abnormalities becoming more prominent in established psychotic illness/schizophrenia. The neural circuits underlying salience and reward processing may be potential targets for delaying or preventing behavioral and neurobiological decline.
The processing of salient and rewarding stimuli is integral to engaging our attention, stimulating anticipation for future events, and driving goal-directed behaviors. Widespread impairments in these processes are observed in psychosis, which may be associated with worse functional outcomes or mechanistically linked to the development of symptoms. Here, we summarize the current knowledge of behavioral and functional neuroimaging in salience, prediction error, and reward. Although each is a specific process, they are situated in multiple feedback and feedforward systems integral to decision making and cognition more generally. We argue that the origin of salience and reward processing dysfunctions may be centered in the subcortex during the earliest stages of psychosis, with cortical abnormalities being initially more spared but becoming more prominent in established psychotic illness/schizophrenia. The neural circuits underpinning salience and reward processing may provide targets for delaying or preventing progressive behavioral and neurobiological decline.
