Retrieval-induced forgetting (RIF) is the observation that retrieval of target information causes forgetting of related nontarget information. A number of accounts of this phenomenon have been proposed, including a context-shift-based account (Jonker, Seli, & Macleod, 2013). This account proposes that RIF occurs as a result of the context shift from study to retrieval practice, provided there is little context shift between retrieval practice and test phases. We tested both claims put forth by this context account. In Experiment 1, we degraded the context shift between study and retrieval practice by implementing a generative study condition that was highly similar to retrieval practice. We observed no degradation of RIF for these generated exemplars relative to a conventional study control. In Experiment 2, we conceptually replicated the finding of RIF following generative study, and tested whether context differences between each of the three phases affected the size of RIF. Our findings were again contrary to the predictions of the context account. Conjointly, the 2 experiments refute arguments about the potential inadequacy of our context shifts that could be used to explain either result alone. Overall, our results are most consistent with an inhibitory account of RIF (e.g., Anderson, 2003).
提取诱发遗忘(RIF)是指对目标信息的提取会导致相关非目标信息被遗忘的现象。针对这一现象已提出了多种解释,其中包括基于情境转换的解释(琼克、塞利和麦克劳德,2013年)。该解释认为,若在提取练习和测试阶段之间情境转换较少,那么提取诱发遗忘是由于从学习到提取练习的情境转换所致。我们对这一情境解释所提出的两种观点都进行了测试。在实验1中,我们通过实施一种与提取练习高度相似的生成性学习条件,来削弱学习与提取练习之间的情境转换。相对于传统学习对照组,我们观察到这些生成范例的提取诱发遗忘并未减弱。在实验2中,我们从概念上重复了生成性学习后提取诱发遗忘的发现,并测试了三个阶段中每个阶段之间的情境差异是否会影响提取诱发遗忘的程度。我们的发现再次与情境解释的预测相悖。综合来看,这两个实验驳斥了那些认为我们的情境转换可能不充分,而单独用其来解释任何一个结果的观点。总体而言,我们的结果与提取诱发遗忘的抑制性解释(例如,安德森,2003年)最为一致。
