AbstractA large literature has demonstrated an abnormal sense of agency (SOA) in schizophrenic individuals. One limitation of such studies is that they focus exclusively on cognitive or perceptual judgments, thus failing to address affective aspects of SOA. In our recent work, we have used instrumental divergence – the distance between outcome probability distributions associated with available actions – as a formal measure of agency, demonstrating an influence of this novel decision variable on behavioral choice preferences and associated neural computations in neurotypical adults. Here, we show that the preference for high instrumental divergence (i.e., for high-agency environments) is significantly modulated by individual differences in positive and negative schizotypy dimensions. Implications for future assessments of clinical populations are discussed.
