The present experiments examined the encoding and retrieval conditions in an item-method-directed forget (IMDF) study that included a novel control condition. In the IMDF condition, half of the items were followed by a remember cue whereas the other half were followed by a forget cue. In a remember-both control condition, half of the items were followed by an item identifier called Set A; whereas the other half of the items were followed by a Set B identifier. At the test, items were recalled as a function of the instruction cue or the set identifier. Across two experiments, directed-forgetting effects and associated benefits were found. Further, results from both studies revealed a new way to demonstrate the benefit of IMDF - directed-forgetting participants made more correct source attributions compared to remember-both participants. These benefits were obtained using a within-subjects IMDF paradigm (Experiment 1) as well as a between-subjects IMDF paradigm (Experiment 2). These patterns of results are consistent with several current theories of item-method-directed forgetting.
本实验在包含一种新的控制条件的项目导向遗忘（IMDF）研究中检查了编码和提取条件。在 IMDF 条件下，一半的项目后面跟着一个记住的提示，而另一半后面跟着一个忘记的提示。在“记住两者”的控制条件下，一半的项目后面跟着一个称为 A 集的项目标识符；而另一半的项目后面跟着 B 集标识符。在测试中，根据指令提示或集合标识符来回忆项目。在两项实验中，都发现了定向遗忘效应和相关的益处。此外，两项研究的结果都揭示了一种展示 IMDF 定向遗忘益处的新方法——与“记住两者”的参与者相比，定向遗忘参与者做出了更多正确的来源归因。这些益处是使用被试内 IMDF 范式（实验 1）和被试间 IMDF 范式（实验 2）获得的。这些结果模式与几种当前的项目导向遗忘理论一致。
