Abstract

The performance of 15 participants with schizophrenia-spectrum disorders (SCZ) on an inferential-reasoning task was compared with that of 15 healthy-control participants (HC). The SCZ group showed poorer inferential reasoning than HCs, independent of their negative or positive symptoms. These findings are consistent with previous research showing deficits of reasoning in schizophrenia, and indicate that this deficit is independent of severity of delusions.
