在两个实验中,我们评估了失忆症患者在单次接触图片后表现出持久知觉启动的能力。学生在单一场合尽可能快地说出图片的名字,然后把相同的图片和新的图片混合起来命名。在实验1中,失忆症患者表现出至少持续7天的完整启动效应。在实验2中,两组的启动效应被证明既依赖于高度具体的视觉信息,也依赖于较少视觉的概念性信息。相比之下,通过准确性和反应时间来评估,患者的识别记忆严重受损。研究结果首次报道了在失忆症患者中,基于一次偶遇而产生的持久启动效应,这种效应在失忆症患者中与在正常患者中一样强烈。再加上最近的其他发现,研究结果表明,持久启动效应和识别记忆依赖于不同的大脑系统。(PsycINFO数据库记录(c) 2017 APA,版权所有)
In 2 experiments, the ability of amnesic patients to exhibit long-lasting perceptual priming after a single exposure to pictures was evaluated. Ss named pictures as quickly as possible on a single occasion and later named the same pictures mixed with new pictures. In Exp 1, amnesic patients exhibited fully intact priming effects lasting at least 7 days. In Exp 2, the priming effect for both groups was shown to depend on both highly specific visual information and on less visual, more conceptual information. In contrast, recognition memory was severely impaired in the patients, as assessed by both accuracy and response time. The results provide the 1st report of a long-lasting priming effect in amnesic patients, based on a single encounter, which occurs as strongly in the patients as in normal Ss. Together with other recent findings, the results suggest that long-lasting priming and recognition memory depend on separate brain systems.(PsycINFO Database Record (c) 2017 APA, all rights reserved)
