Understanding the symptoms of schizophrenia using visual scan paths.
BACKGROUND
This paper highlights the role of the visual scan path as a physiological marker of information processing, while investigating positive symptomatology in schizophrenia.


METHODS
The current literature is reviewed using computer search facilities (Medline).


RESULTS
Schizophrenics either scan or stare extensively, the latter related to negative symptoms. Schizophrenics particularly scan when viewing human faces.


CONCLUSIONS
Scan paths in schizophrenics are important when viewing meaningful stimuli such as human faces, because of the relationship between abnormal perception of stimuli and symptomatology in these subjects.
