Item-based directed forgetting (DF) was tested using 2-alternative forced-choice recognition to examine the effects of forgetting instructions on memory for perceptual detail and gist of categorised pictures of scenes and objects in three experiments. When the distractor is from the same category as the target (exemplar test condition), discrimination must be based on memory for perceptual details, whereas recognition can be based on gist or general category information when the distractor is from a novel category (novel test condition). Recognition accuracy was greater for Remember-cued than Forget-cued pictures when discrimination must be based on perceptual details in the exemplar test condition but not when discrimination could be based on gist in the novel test condition. Accuracy in scene and object recognition is greater for gist than for perceptual details, and DF instructions serve to reduce recognition memory based on perceptual details.
项目导向的定向遗忘（DF）通过 2 种选择强制识别来进行测试，以检验遗忘指令对场景和物体分类图片的知觉细节和概要记忆的影响。当分心物与目标（范例测试条件）来自同一类别时，必须基于知觉细节进行辨别，而当分心物来自新类别（新测试条件）时，识别可以基于概要或一般类别信息。在必须基于范例测试条件中的知觉细节进行辨别时，与忘记提示的图片相比，记住提示的图片的识别准确率更高，但在可以基于新测试条件中的概要进行辨别时则不然。在场景和物体识别中，概要的准确性高于知觉细节，而 DF 指令则有助于减少基于知觉细节的识别记忆。
