已经发现，经历妄想的精神分裂症受试者在执行抽象概率判断任务时，要求较少的信息，并且比控制受试者更确定他们的决定的正确性（Huq，Garety和Hemsley，1988）。本研究采用了一个以熟悉的情境为刺激的归纳推理任务，考察了被试的推理策略和推理过程。12名被诊断为精神分裂症并患有妄想症的受试者与匹配的抑郁症患者和正常对照组进行了比较。结果发现，与早期的研究一致，被欺骗的受试者在做出决定之前要求的信息较少，并且产生了更差的判断。它的结论是，存在一个核心赤字，独立的任务或背景。
Schizophrenic subjects who experience delusions have been found to request less information and are more certain about the correctness of their decision than control subjects when performing abstract probability judgment tasks (Huq, Garety & Hemsley, 1988). The present study employed an inductive reasoning task using familiar contextual stimuli to investigate the strategies employed and to observe the stages in reasoning. Twelve subjects with a diagnosis of schizophrenia and experiencing delusions were compared with matched depressed patients and normal controls on a version of the “Twenty Questions Game”. It was found, consistent with the earlier study, that the deluded subjects requested less information before making a decision, and produced poorer judgments. It is concluded that there exists a core deficit, independent of task or context.
