AbstractExecutive dysfunctions have been consistently demonstrated in patients with schizophrenia. This study aimed to investigate deficits in specific executive functioning components, namely working memory and inhibition, in schizophrenia. In study 1, a set of neurocognitive function tests was administered to 41 patients with schizophrenia and 25 healthy controls to capture specific components of executive functioning, including semantic inhibition (the Stroop-like paradigm and the Chinese Version of the Hayling Sentence Completion Test (HSC)), working memory (the spatial n-back), and response inhibition (the stop signal task (SST)). Results showed that schizophrenia patients did significantly worse than controls under both working memory and inhibition demands in the Stroop-like paradigm. In particular, patients were impaired when inhibiting a semantically associated response; and performance was correlated with negative symptoms. In study 2, we employed a modified semantic inhibitory error monitoring paradigm to examine whether patients with schizophrenia (n = 11) were impaired in semantic inhibitory error monitoring or not as compared to 11 healthy controls. The results suggested that patients with schizophrenia in this study remained intact in semantic inhibition error monitoring. There was no difference in the semantic inhibitory monitoring performance between healthy controls and patients with schizophrenia. Taken together, these results suggested impaired working memory context maintenance and semantic inhibition in schizophrenia patients, and these impairments were related to clinical symptoms of schizophrenia.
