Deficient gaze pattern during virtual multiparty conversation in patients with schizophrenia.

Area of Science:

• Psychiatry
• Neuroscience
• Virtual Reality Applications

Background:

• Social interaction deficits are key in schizophrenia, but often studied in simplified one-on-one settings.
• Real-world social interactions frequently involve multiple people, presenting greater complexity.
• Virtual reality (VR) offers a controlled environment to study complex social behaviors.

Purpose of the Study:

• To investigate social behavior patterns in patients with schizophrenia during virtual multiparty conversations.
• To identify specific gaze behaviors and their correlation with cognitive abilities in this context.
• To explore the utility of VR for assessing social impairments in schizophrenia.

Main Methods:

• Twenty-three patients with schizophrenia and 22 healthy controls participated.
• Participants engaged in a virtual three-party conversation task.
• The task involved varying conversational roles, emotional contexts, and speaking/listening phases.

Main Results:

• Schizophrenia patients showed a negative correlation between gaze in the between-avatar space and reasoning ability during listening.
• Patients exhibited increased gaze in the between-avatar space during speaking, unrelated to attention.
• These findings suggest active avoidance of eye contact in multiparty social settings.

Conclusions:

• Patients with schizophrenia display distinct eye contact avoidance patterns in virtual multiparty conversations.
• VR-based social interaction tasks may be valuable for understanding and measuring social deficits in schizophrenia.
• This approach could lead to novel diagnostic and therapeutic strategies.
