Abstract

Introspective accuracy (IA) refers to the ability to accurately assess one's own skills and capabilities. Recent work provides evidence of IA deficits in schizophrenia that are predictive of everyday functioning. Thus, IA deficits are an important target to understand mechanistically. The current study used fMRI to assess neural activation in 32 healthy controls and 31 individuals with schizophrenia as they completed IA and control versions of a social cognitive task (i.e., emotion recognition). Analyses revealed different areas of IA-specific neural activity between groups including activations of rostrolateral prefrontal cortex (rlPFC) and dorsal anterior cingulate cortex in healthy individuals that were absent in patients. Direct group comparisons revealed greater IA-specific activation for healthy individuals in right rlPFC, a region thought to be critical for successful IA. For healthy individuals only, activation in rlPFC was positively correlated with IA ability, but no association was observed for patients. Further, among individuals with schizophrenia, increased activation of rlPFC during judgments of IA was positively correlated with better informant-reported interpersonal functioning. These results suggest that reduced specialization of IA-related neural activation may contribute to impaired IA in schizophrenia and also highlight IA as a potential target for remediation programs aimed at improving real-world functioning.
