The present report is of the application of Treisman's (1964) model of perceptual functioning 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 (1957b) 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.
本报告阐述了将特雷斯曼(1964年)的知觉功能模型应用于精神分裂症幻觉研究的情况。研究假设,幻觉症患者在听觉阈限任务中的表现,就好像他们拥有一个显示出高水平自发神经活动(In)的知觉系统。在纯音强度的韦伯函数方面,对三组人群进行了比较:精神分裂症幻觉症患者、老年人和焦虑神经症患者。根据这些函数,使用巴洛(1957b)的方法计算出In的估计值。未发现组间差异。本文提出了对精神分裂症幻觉的另一种解释,即对正常水平的背景感觉活动的反应性增加。
