我们使用定向遗忘（DF）范式的项目方法研究了情绪对项目和源记忆的作用。我们预测情绪会产生源记忆障碍，因为情绪会使R和F项目的记忆强度彼此相似，从而使区分要记住的项目（R项目）和要忘记的项目（F项目）变得更加困难。向参与者展示了消极唤起、积极唤起和中性的图片。每拍完一张照片后，他们都会收到一条记住或忘记这张照片的指令。在检索时，参与者被要求回忆 R 和 F 项目，并指出每个项目是 R 还是 F 项目。消极唤起的图片比积极唤起或中性的图片的回忆要高。此外，DF 发生在积极唤起和中性的图片中，而 DF 对于消极唤起的图片不显着。更重要的是，引起负面情绪的图片，尤其是含有暴力内容的图片，比其他图片类型更容易产生错误归因错误，这支持了负面情绪可能会导致源记忆损伤的观点，尽管目前尚不清楚这种损伤是否发生在编码或检索时。
We investigated the role of emotion on item and source memory using the item method of directed forgetting (DF) paradigm. We predicted that emotion would produce source memory impairment because emotion would make it more difficult to distinguish between to-be-remembered (R items) and to-be-forgotten items (F items) by making memory strength of R and F items similar to each other. Participants were presented with negatively arousing, positively arousing, and neutral pictures. After each picture, they received an instruction to remember or forget the picture. At retrieval, participants were asked to recall both R and F items and indicate whether each item was an R or F item. Recall was higher for the negatively arousing than for the positively arousing or neutral pictures. Further, DF occurred for the positively arousing and neutral pictures, whereas DF was not significant for the negatively arousing pictures. More importantly, the negatively arousing pictures, particularly the ones with violent content, showed a higher tendency of producing misattribution errors than the other picture types, supporting the notion that negative emotion may produce source memory impairment, even though it is still not clear whether the impairment occurs at encoding or retrieval.
