The Effects Of Positive Conditioning And Contingent Reinforcement On Dual Modality Reaction Times Of Chronic Nonparanoid Schizophrenics

Chronic schizophrenics have consistently been shown to exhibit slower reaction time (RT) than normal individuals when required to respond as rapidly as possible to the presentation or cessation of a stimulus. RT deficit occurs whether stimuli are presented visually or in both visual and auditory modalities. The RT resulting from a subject responding to a known perceptual modality or stimulus has been compared to the RT resulting from a subject responding to an unknown perceptual modality or stimulus.
