对新异联系的启动效应是内隐记忆的一种形式 ,又称联想启动。采用知觉辨认任务 ,探讨额叶损伤与联想启动的关系。 2 5例额叶损伤病人及 18例匹配的正常被试参与实验。结果表明 ,额叶受损病人辨认旧词对与重组词对的正确率没有明显差别 ;而且 ,轻度记忆损伤的额叶病人再认成绩正常 ,但联想启动值低于对照组 ,内隐记忆和外显记忆相分离。相关分析还发现了联想启动值与威斯康星卡片分类测验中的坚持性错误数、坚持性反应数和语词流畅性等有中度相关。这些结果提示 ,额叶不仅与情节记忆、工作记忆等外显记忆有关 ,也参与了以非相关词对为材料的联想启动。
The starting effect on the new relationship is a form of implicit memory, also known as Lenovo started. Using perceptual identification task to explore the relationship between the frontal lobe injury and the initiation of the association. Twenty-five patients with frontal lobe injury and 18 matched normal subjects participated in the experiment. The results showed that there was no significant difference between the correct word recognition and the correct word recognition in the frontal lobe patients. Moreover, the patients with mild memory impairment in the frontal lobe recognized the normal results, but the association values were lower than those in the control group and implicit memory Separated from explicit memory. Correlation analysis also found that there was a moderate correlation between association initiation values and adherence errors in the Wisconsin Card Sorting Test, persistence of sexual responses, and verbal fluency. These results suggest that the frontal lobe is not only related to episodic memory, working memory and other explicit memory, but also involved in the association of unrelated words as the starting material.
