Early Visual Processing Is Associated With Social Cognitive Performance in Recent-Onset Schizophrenia

Area of Science:

• Neuroscience
• Cognitive Psychology
• Psychiatry

Background:

• Early-stage visual processing deficits are common in chronic schizophrenia.
• Impaired visual processing is linked to social cognition deficits in schizophrenia.
• The relationship between early visual processing and social cognition in recent-onset schizophrenia (ROSz) is not well understood.

Purpose of the Study:

• To investigate early-stage visual processing and social cognitive performance in recent-onset schizophrenia (ROSz).
• To examine the association between early visual processing and social cognition in ROSz.
• To test a cascade model of information processing in early schizophrenia.

Main Methods:

• Thirty-two individuals with ROSz and 20 healthy controls (HC) completed a visual backward masking task (Object Masking) to assess early visual processing (0-125 ms).
• Participants also completed emotion identification (Emotion Biological Motion, EmoBio) and theory of mind (The Awareness of Social Inference Test, TASIT) tasks.
• Group differences were analyzed using ANOVAs and t-tests; associations were examined using correlations and regressions.

Main Results:

• ROSz patients exhibited impaired object identification in the visual masking task compared to HC.
• ROSz patients performed worse on both EmoBio and TASIT tasks, with particular difficulty in sarcasm detection on TASIT.
• Better performance on Object Masking in ROSz was correlated with better performance on both social cognition tasks.

Conclusions:

• Individuals with ROSz demonstrate significant impairments in early visual processing and both low-level and high-level social cognition.
• Early visual processing deficits in ROSz are associated with social cognitive impairments, supporting a cascade model.
• Findings suggest that interventions targeting early visual processing may positively impact social cognitive functions in ROSz.
