进行了4个实验,探讨启动效应在配对联想学习中的作用。所有4个实验的受试者为5名男性和3名女性患有Korsakoff综合征的酗酒者(平均年龄53.8岁; WAIS-R智商85-203)。对照组为26名男性酗酒者(平均年龄47.6岁)。实验一说明了遗忘型(Korsakoff)学生的记忆损害与其完整启动能力之间的区别。在实验二中,健忘的Ss表现出良好的配对联想学习相关的单词对,但控制表现显着更好。实验二还发现,遗忘者对相关词对的遗忘与词启动的衰减具有相同的时程。实验三表明,健忘的Ss一样好,在学习相关的词对时,词联想测试。实验四表明,健忘的学生表现出正常的启动时,他们被要求自由联想到的话,语义相关的先前提出的话。结果表明,启动效应和相关词的配对联想学习依赖于激活,这是一个过程中保存的健忘症。激活是一种短暂的现象,被认为是对预先存在的表征起作用并促进对预先存在的表征的访问。(67参考)(PsycInfo数据库记录(c)2022阿帕,保留所有权利)
Conducted 4 experiments investigating the role of priming effects in paired-associate learning. Ss for all 4 experiments were 5 male and 3 female alcoholics (mean age 53.8 yrs; WAIS—R IQs 85–203) with Korsakoff syndrome. Control Ss were 26 male alcoholics (mean age 47.6 yrs). Exp I illustrated the distinction between the memory impairment of amnesic (Korsakoff) Ss and their intact priming ability. In Exp II, amnesic Ss showed good paired-associate learning for related word pairs but controls performed significantly better. Exp II also showed that the forgetting of related word pairs by amnesic Ss followed the same time course as the decay of word priming. Exp III showed that amnesic Ss were as good as controls at learning related word pairs when word-association tests were used. Exp IV showed that amnesic Ss exhibited normal priming when they were asked to free associate to words that were semantically related to previously presented words. Results indicate that both priming effects and paired-associate learning of related words depended on activation, a process that is preserved in amnesia. Activation is a transient phenomenon presumed to operate on and facilitate access to preexisting representations.(67 ref)(PsycInfo Database Record (c) 2022 APA, all rights reserved)
