摘要情绪增强记忆(EEM)描述了情绪刺激相对于非情绪刺激的强健记忆优势。虽然对情绪项目进行了广泛的研究,但尚不清楚EEM效应是否延伸到中性项目的情绪背景的来源记忆。在两项预先登记的研究中,我们系统地操纵了参与者之间的来源效价(正、负)和参与者内部的来源唤醒(高、低、中性-低)。在实验一(Lab Study,N = 80)中,我们使用情绪声源,并将它们与中性图片一起呈现。在实验2(Online Study,N = 172)中,我们使用带有中性词的情绪背景图片来类似地操控来源情绪。基于多项模型的分析表明,在两个实验中,效价或唤醒对源记忆没有普遍影响。在实验1中,源记忆因负性高唤醒源而受损,但在实验2中没有重复。总体而言,我们得出结论:源情绪(价态、唤醒或它们的任何特定组合)对源记忆没有增强记忆的作用,分离了源记忆和项目记忆之间的情绪效应。此外,我们认为,如果使用的情感材料在数量上有限,那么依赖于材料的影响具有更大的权重,就像标准的来源监控范式只使用很少的来源一样。
ABSTRACT Emotion-enhanced memory (EEM) describes the robust memory advantage of emotional over non-emotional stimuli. While extensively investigated with emotional items, it is unclear whether the EEM effect extends to source memory for a neutral item's emotional context. In two pre-registered studies, we systematically manipulated source valence (positive, negative) between participants and source arousal (high, low, neutral-low) within participants. In Experiment 1 (lab study, N = 80), we used emotional sound sources and presented them together with neutral pictures as items. In Experiment 2 (online study, N = 172), we used emotional background pictures with superimposed neutral item words to similarly manipulate source emotionality. Multinomial model-based analysis showed no general effects of valence or arousal on source memory across both experiments. Source memory was impaired for the negative high-arousing source in Experiment 1 but this did not replicate in Experiment 2. Altogether, we conclude that there are no memory-enhancing effects of source emotionality (valence, arousal, or any specific combination thereof) on source memory, dissociating emotionality effects between source and item memory. Additionally, we propose that material-dependent influences carry more weight if the used emotional material is limited in number, as is the case in the standard source-monitoring paradigm employing few sources only.
