这一系列实验试图阐明由于训练和测试之间的上下文变化（上下文转移效应 [CSE]）而导致的检索失败在遗忘中的作用。由于自发性遗忘 (SF) 通常被认为反映检索失败，因此检查了三种已知可减轻 SF 的操作对由于短暂延迟（24 小时）上下文中的显式变化而导致的遗忘的影响。预测试暴露于涉及训练中的强化物（实验1）、预测试安非他明给药（实验2）和过度训练（实验3）的提醒治疗减轻了SF和CSE，支持了CSE反映检索缺陷的观点。讨论了 SF 上下文更改帐户的含义。
This series of experiments sought to clarify the role of retrieval failure in forgetting that results from a change in context between training and testing (the context shift effect [CSE]). Because spontaneous forgetting (SF) is generally considered to reflect a retrieval failure, the effects of three manipulations known to alleviate SF were examined on forgetting due to an explicit shift in context at a short delay (24 hr). Pretest exposure to a reminder treatment involving the reinforcer from training (Experiment 1), pretest amphetamine administration (Experiment 2), and overtraining (Experiment 3) alleviated both SF and the CSE, supporting the view that the CSE reflects a retrieval deficit. Implications for the context change account of SF are discussed.
