Previous studies showed that attentional task performance of schizophrenics was significantly inferior to that of normals. The classical Stroop Color-Word Interference Test is an example of such attentional tasks and performance on the "reverse" Stroop task is reported to discriminate schizophrenics from normals better than the regular Stroop task. These results suggest that schizophrenics are more susceptible to "reverse" Stroop interference in reading incongruent word-color combinations than normals. The group version of the Stroop and reverse-Stroop Color-Word Test, where the response is to choose a matching alternative, was used to test the hypothesis. The results virtually supported the hypothesis. In addition, interference was closely related to the patient's control of impulsiveness. It was suggested that schizophrenics have generation (or translation) deficits between different codes.
先前的研究表明，精神分裂症患者的注意力任务表现明显低于正常人。经典的斯特鲁普颜色-文字干扰测试就是这类注意力任务的一个例子，据报道，在“反向”斯特鲁普任务中的表现比常规斯特鲁普任务更能区分精神分裂症患者和正常人。这些结果表明，与正常人相比，精神分裂症患者在阅读不一致的文字-颜色组合时更容易受到“反向”斯特鲁普干扰。斯特鲁普和反向斯特鲁普颜色-文字测试的团体版本（即通过选择匹配的选项来做出反应）被用于检验这一假设。结果实际上支持了这一假设。此外，干扰与患者对冲动的控制密切相关。有人提出，精神分裂症患者在不同代码之间存在生成（或转换）缺陷。
