本研究旨在探讨重复启动与外显记忆任务之间的功能和神经心理分离。显式和隐式版本的干完成任务管理一组健忘症和一组对照组。在实验1中，显式和隐式干完成显着更高时，相同的呈现方式被用于学习和测试比时，在模式的变化，从学习到测试发生。遗忘者内隐完成能力正常，外显完成能力不足。实验二揭示了优势的语义语音条件下，只有在明确的任务，只有在控制对象。在语音和语义条件下的内隐任务和语音条件下的外显任务中，痴呆患者完成了与正常受试者相同百分比的单词，但在有意完成语义处理的单词方面存在不足。这些结果可能的解释进行了讨论，根据理论模型，区分记忆任务沿着一个显式-隐式二分法（多记忆系统理论）或沿着一个感知-概念二分法（转移适当的程序方法），和替代的理论立场进行评估关于重复启动和记忆缺陷的健忘症患者。版权所有（C）1996 Elsevier Science Ltd.
This study was aimed at investigating functional and neuropsychological dissociations between repetition priming and explicit memory tasks. The explicit and implicit versions of the stem completion task were administered to a group of amnesics and a group of control subjects. In Experiment 1 both the explicit and implicit stem completions were significantly higher when the same presentation modality was used for studying and testing than when a change in modality from studying to testing occurred. Amnesics had normal implicit and deficient explicit completion performance. Experiment 2 revealed an advantage of the semantic over the phonological condition only in the explicit task and only in control subjects. Amnesic patients completed the same percentage of words as normal subjects in the phonological and semantic conditions of the implicit task and in the phonological condition of the explicit task but were deficient in intentionally completing semantically processed words. Possible interpretations of these results are discussed according to theoretical models that distinguish memory tasks along an explicit-implicit dichotomy (multiple memory system theory) or along a perceptual-conceptual dichotomy (transfer-appropriate procedures approach), and alternative theoretical positions are evaluated regarding repetition priming and memory deficits in amnesic patients.
