This study compared matched groups of patients with acute schizophrenia and with depression on three tests used in the assessment of schizophrenic thinking disorder. Most measures derived from these tests significantly differentiated the groups; however, within the schizophrenic group there were no significant correlations between scores on the three tests. Further data were available from a choice reaction-time card-sorting task, from which estimates of distractability, stimulus decision time, response decision time, and movement time, were obtained. Only one significant relation was found between these measures and scores on the clinical tests. The possible confounding effects of intelligence and responsiveness are discussed. It is argued that more direct measures of the latter are preferable to interpreting tests of thinking disorder in terms of information processing deficits.
本研究比较了急性精神分裂症患者和抑郁症患者的匹配组，这些患者接受了三项用于评估精神分裂症思维障碍的测试。这些测试得出的大多数指标都能显著区分这两组；然而，在精神分裂症组中，三项测试的得分之间没有显著相关性。从一项选择反应时卡片分类任务中可获得更多数据，通过该任务可得出注意力分散度、刺激决策时间、反应决策时间和动作时间的估计值。在这些指标与临床测试得分之间仅发现了一种显著关系。文中讨论了智力和反应性可能产生的混杂效应。有人认为，对于后者，采用更直接的测量方法比根据信息处理缺陷来解释思维障碍测试更为可取。
