Relationship between abstract thinking and eye gaze pattern in patients with schizophrenia

Area of Science:

• Cognitive Neuroscience
• Psychiatry

Background:

• Abstract thinking relies on visual information integration.
• Schizophrenia is associated with altered eye movement and limited visual exploration.
• Understanding these deficits is crucial for cognitive rehabilitation.

Purpose of the Study:

• To investigate the relationship between abstract thinking ability and eye gaze patterns in schizophrenia.
• To utilize a novel theme identification task to assess cognitive function.
• To explore objective measures for abstract thinking in schizophrenia.

Main Methods:

• Twenty schizophrenia patients and 22 healthy controls performed a theme identification task.
• Participants selected words describing picture themes.
• Eye gaze patterns were recorded using an eye tracker.

Main Results:

• Schizophrenia patients had lower theme identification accuracy and fewer fixations/saccades.
• A significant positive correlation was found between correct rate and fixation count in patients.
• No significant correlation was observed in healthy controls.

Conclusions:

• Schizophrenia is characterized by impaired abstract thinking and reduced gaze quality.
• These cognitive and oculomotor deficits are positively associated.
• Theme identification and eye gaze metrics offer objective assessment tools for abstract thinking in schizophrenia.
