BACKGROUND
Up to now, in the Deese-Roediger-McDermott (DRM) paradigm, the lower production of false memories in Alzheimer's disease has been explained in terms of non-activation of the critical lure.
OBJECTIVES
The aim of this study was to examine the critical lure activation process from items of DRM lists in Alzheimer's patients, using a free association task.
METHOD
Twenty-six young adults, 25 older adults, and 17 Alzheimer's patients performed a free association task with DRM words.
RESULTS
Analyses indicated that Alzheimer's patients produced as many critical lures in the free association task as healthy older participants, but significantly fewer than younger participants.
CONCLUSION
Our results suggest that the low production of critical lures in DRM tasks usually reported in Alzheimer's patients might not be due to a semantic deficit that prevents the activation of the critical lure.
背景
到目前为止，在 Deese-Roediger-McDermott（DRM）范式中，阿尔茨海默病患者产生虚假记忆的频率较低，这被解释为关键诱饵未被激活。
目的
本研究旨在使用自由联想任务来检查阿尔茨海默病患者从 DRM 列表项目中激活关键诱饵的过程。
方法
26 名年轻成年人、25 名老年成年人和 17 名阿尔茨海默病患者进行了 DRM 词的自由联想任务。
结果
分析表明，阿尔茨海默病患者在自由联想任务中产生的关键诱饵与健康的老年参与者一样多，但明显少于年轻参与者。
结论
我们的结果表明，在阿尔茨海默病患者中通常报告的 DRM 任务中关键诱饵产生率低，可能不是由于语义缺陷阻止了关键诱饵的激活。
