Abstract
Triesman''s model of perceptual functioning was applied to the study of schizophrenic hallucinations. It was hypothesized that hallucinators would perform on an auditory threshold task as if possessing a perceptual system showing high levels of spontaneous neural activity (In). Three groups were compared on the Weber functions for pure tone intensity: schizophrenic hallucinators, old people and anxiety neurotics. From these functions, estimates of In were calculated using Barlow''s method. No group differences were found. An alternative explanation of schizophrenic hallucinations, in terms of increased responsiveness to normal levels of background sensory activity, is proposed.This publication has 4 references indexed in Scilit:
