Auditory discrimination, attention, learning, and memory in paranoid schizophrenics.
The present research was designed to assess auditory discrimination, attention, memory, and learning in paranoid schizophrenic patients using a dichotic listening procedure consisting of attending to a signal or a story channeled only to one ear. A sample of 24 paranoid schizophrenics and 24 normal controls volunteered. In Experiment 1, 12 schizophrenics and 12 controls attended to the signal while shadowing the story. The task of the other 12 clinical and 12 normal subjects in Experiment 2 was identical to Experiment 1 with the exception that the subjects did not shadow the story. In each experiment, subjects completed three trials as well as three evaluations of the story. The results indicated that schizophrenics showed substantial attentional deficits in comparison to normal controls.
