Summary
Schizophrenia patients exhibit distinct visual scan paths, scanning faces more than staring. This visual behavior is linked to their positive and negative symptoms.
Area of Science:
- Neuroscience
- Psychiatry
- Cognitive Psychology
Background:
- Visual scan path as a physiological marker of information processing.
- Investigating positive symptomatology in schizophrenia.
Purpose of the Study:
- To highlight the role of visual scan path in information processing.
- To investigate positive symptomatology in schizophrenia.
Main Methods:
- Literature review using Medline database.
Main Results:
- Schizophrenic patients exhibit either extensive scanning or staring.
- Staring is associated with negative symptoms.
- Schizophrenics show increased scanning when viewing human faces.
Conclusions:
- Visual scan paths are significant in schizophrenia, especially when viewing meaningful stimuli like faces.
- Abnormal visual perception in schizophrenia correlates with symptomatology.
