Schizophrenia is a complex mental disorder impacting cognitive function.
Previous research has yielded mixed results on cognitive deficits in schizophrenia.
Purpose:
To compare cognitive functions in schizophrenic patients versus a matched control group.
To investigate differences in association tasks of varying complexity.
Summary:
Schizophrenic patients showed no significant difference in basic cognitive tasks compared to controls.
In complex tasks, schizophrenic patients exhibited overinclusion and overexclusion of associations, suggesting a cognitive organizing principle deficit.
Impact:
Findings suggest a specific cognitive deficit in higher-order processing in schizophrenia.
Implications for understanding rehabilitation, creativity, and art in schizophrenic individuals.
