This paper attempts to indicate the relevance of Broadbent's recent views on the methods by which the systematic selection of information takes place, for the study of attention deficits in schizophrenia. A two-stage model of attention is briefly described, the distinction between "filtering" (stimulus set) and "pigeon-holing" (response set) being emphasized. In an attempt to clarify the nature of the schizophrenics attention defect, various experiments are reviewed and interpreted within Broadbent's theoretical framework. Studies indicate inefficiencies in both the "filtering" and "pigeon-holing" mechanisms. The need for experiments specifically designed to identify the locus of the schizophrenic attention defect, in various subgroups of schizophrenics, is indicated.
本文试图指出布罗德本特近期关于信息系统选择方式的观点与精神分裂症注意力缺陷研究的相关性。简要描述了一个两阶段的注意力模型，强调了“过滤”（刺激集）和“分类”（反应集）之间的区别。为了阐明精神分裂症患者注意力缺陷的本质，在布罗德本特的理论框架内对各种实验进行了回顾和解读。研究表明“过滤”和“分类”机制均存在低效性。指出了需要专门设计实验来确定精神分裂症不同亚组中注意力缺陷的位置。
