The present study focused on post-error slowing and tested the hypothesis that post-error slowing is driven by attentional mechanisms elicited by the unexpected nature of the error. Outcome expectancy was manipulated by using an adaptive task allowing us to control accuracy (either 35% or 75% accuracy). We showed that patients slow down after unexpected feedback, and most interesting, that this effect was enhanced and larger than the slowing in controls when the intertrial interval was short. This suggests increased orienting to unexpected action outcomes in schizophrenia in line with previous studies demonstrating increased distractibility in schizophrenia.
