Schizophrenics, depressives, and normal controls were tested on a binaural listening task in which pairs of simultaneous continuous prose passages were presented. Subjects were required to shadow one passage of each pair and ignore th other. The passages in each pair, although differing markedly in content, were inseparable on the basis of their physical features. As predicted, the performance of schizophrenics on such a task was markedly worse than that of the other groups. The results were interpreted within the framework of Broadbent's model of selective attention (Broadbent, D.E. Decision and Stress. Academic Press, London, 1971). This makes a distinction between "pigeonholing" (response set) and "filtering" (stimulus set). The present findings are compatible with a schizophrenic defect at the pigeonholing stage. In contrast, the evidence for a defect in filtering specific to schizophrenia remains weak, due to the use of inappropriate control groups in a number of studies reviewed.
对精神分裂症患者、抑郁症患者和正常对照组进行了一项双耳聆听任务测试,在该任务中呈现成对的同时连续散文段落。要求受试者跟读每对段落中的一个段落,并忽略另一个。每对段落虽然内容明显不同,但根据其物理特征无法区分。正如预测的那样,精神分裂症患者在这项任务上的表现明显比其他组差。研究结果在布罗德本特的选择性注意模型(布罗德本特,D.E.《决策与压力》。学术出版社,伦敦,1971年)框架内进行了解释。该模型区分了“分类”(反应集)和“过滤”(刺激集)。目前的研究结果与精神分裂症患者在分类阶段的缺陷相符。相比之下,由于在一些综述研究中使用了不适当的对照组,关于精神分裂症特有的过滤缺陷的证据仍然不足。
