精神分裂症(n= 21),双相(n= 18),和正常对照组(n= 21)进行了比较的语义启动的单词识别措施。该任务涉及相关的,中性的,和不相关的词对的介绍,在每对第二个字(目标词)是在一个降级的形式。促进作用被定义为相关词对的目标词识别准确率减去中性词对的准确率。滴定,通过操纵目标词的降解,实现了,用于保持每个主题的相关和中性项目的整体准确性在约50%。该程序最大限度地减少了总体准确度对差异评分的人为影响。精神分裂症患者的易化能力高于正常对照组和双相情感障碍组。双相情感障碍受试者与对照受试者没有差异。这些结果支持Maher的假设,即语义启动效应在精神分裂症中被增强。(PsycInfo数据库记录(c)2022阿帕,保留所有权利)
Schizophrenic (n= 21), bipolar (n= 18), and normal control subjects (n= 21) were compared on a word recognition measure of semantic priming. The task involved the presentation of related, neutral, and unrelated word pairs; the second word (target word) in each pair was presented in a degraded form. Facilitation was defined as the accuracy of target word recognition for the related word pairs minus accuracy for the neutral word pairs. Titration, achieved by manipulating the degradation of the target word, was used to maintain each subject's overall accuracy for related and neutral items at approximately 50%. This procedure minimized the artifactual effects of overall accuracy on the difference score. Schizophrenics exceeded both normal control subjects and bipolar subjects on facilitation. Bipolar subjects did not differ from control subjects. The results support Maher's hypothesis that semantic priming effects are heightened in schizophrenia.(PsycInfo Database Record (c) 2022 APA, all rights reserved)
