The use of linguistic context in positively thought-disordered (TD) schizophrenics was investigated through examination of their performance on an on-line word-monitoring task. Controls and non-TD schizophrenics took longer to recognize words preceded by linguistic anomalies compared with words in normal sentences. Compared with both other groups, TD schizophrenics showed significantly smaller differences in reaction time, suggesting that they were relatively insensitive to linguistic violations. TD schizophrenics were also less sensitive to linguistic violations in an off-line version of the task, in which they judged whether the sentences "made sense." Finally, these participants produced more errors on a verbal fluency task than did non-TD schizophrenics or normal controls. These findings are consistent with the theory that schizophrenic thought disorder arises from a deficit in the use of linguistic context to process and produce speech.
通过考察积极思维紊乱（TD）的精神分裂症患者在一项在线单词监测任务中的表现，对语言语境在他们身上的运用情况进行了研究。与正常句子中的单词相比，对照组和非TD精神分裂症患者识别语言异常前面的单词花费的时间更长。与其他两组相比，TD精神分裂症患者在反应时间上的差异显著更小，这表明他们对语言违规相对不敏感。在该任务的离线版本中，即让他们判断句子是否“有意义”时，TD精神分裂症患者对语言违规也较不敏感。最后，这些参与者在言语流畅性任务上比非TD精神分裂症患者或正常对照组产生了更多错误。这些发现与精神分裂症思维障碍源于利用语言语境来处理和产生言语方面存在缺陷这一理论相一致。
