Cognitive concomitants of hemispheric dysfunction in schizophrenia.

R E Gur

    Archives of General Psychiatry
    |March 1, 1979
    PubMed
    Summary

    Schizophrenic patients exhibit slower reaction times and lower response quality compared to controls. However, they show faster processing for successive visual stimuli, suggesting overactivation of the left hemisphere.

    Area of Science:

    • Neuroscience
    • Cognitive Psychology
    • Psychiatry

    Background:

    • Schizophrenia is a complex mental disorder affecting cognitive functions.
    • Previous research suggests lateralized brain dysfunction in schizophrenia.

    Purpose of the Study:

    • To investigate visual processing differences in schizophrenic patients.
    • To explore hemispheric activation patterns during a visual detection task.

    Main Methods:

    • Forty-eight schizophrenic patients and 24 controls performed a picture-difference detection task.
    • Stimuli were presented successively and simultaneously.
    • Performance was measured by reaction time and response quality.

    Main Results:

    • Controls outperformed schizophrenics in overall performance.
    • Schizophrenics showed faster reaction times in successive presentation, unlike controls.
    • Depressed patients displayed results similar to controls, not schizophrenics.

    Conclusions:

    • Schizophrenic patients may exhibit overactivation of their dysfunctional left hemisphere.
    • These findings are specific to schizophrenia and not a general characteristic of psychosis.
