[Disorders in the mechanism of information selection in schizophrenic patients].
Two groups of schizophrenics with negative and positive syndromes were studied by registering cortical evoked potentials in response to acoustic stimuli of different meaning (odd-ball paradigm). Disfunction of selective attention is related to the impaired ability to differentiate relevant and irrelevant information. Disturbances of information selection were more pronounced in the patients with paranoid schizophrenia.
