两个实验使用Deese/Roediger-McDermott （DRM）范式检验了注意力资源减少对情绪性刺激产生错误记忆的影响。先前的研究表明，情绪信息通常比中性信息更容易被记住，并且对情绪信息的增强记忆依赖于自动或受控的神经处理。旨在减少编码时注意资源的行为研究支持神经影像学研究结果，表明高唤醒负性刺激更多地依赖于自动加工，而高唤醒正性刺激更多地依赖于控制加工。目前还没有研究考察产生情绪性错误记忆所需的注意力资源。在实验1中，在完全注意或分散注意（DA）条件下研究了消极、积极和中性DRM列表；在实验2中，在快速（20 ms）或慢速（2000 ms）条件下研究了消极和中性DRM列表。在DA和快速呈现条件下，阴性临界诱饵的错误记忆识别率高于阳性（实验1）和中性（实验1和2）临界诱饵。这是我们第一次意识到消极的错误记忆与自动神经处理有关，而积极的和无价的中性错误记忆与更受控制的处理有关。
Two experiments examined the effect of reduced attentional resources on false memory production for emotionally valenced stimuli using the Deese/Roediger-McDermott (DRM) paradigm. Prior research has demonstrated that emotional information is often better remembered than neutral information and that enhanced memory for emotional information is dependent on either automatic or controlled neural processing. Behavioral studies designed to reduce attention resources at encoding have supported neuroimaging findings that indicate high arousal negative stimuli rely more on automatic processing but positive high arousal stimuli rely more on controlled processing. No study has yet examined the attentional resources required to produce emotionally valenced false memories. In Experiment 1, negative, positive, and neutral DRM lists were studied under full or divided attention (DA) conditions, and in Experiment 2, negative and neutral DRM lists were studied under fast (20 ms) or slow (2,000 ms) presentation conditions. Under DA and speeded presentation conditions, higher false memory recognition rates were found for negative compared with positive (Experiment 1) and neutral (Experiments 1 and 2) critical lures. This is the first demonstration of which we are aware that suggests negative false memories are associated with automatic neural processing, whereas positive and nonvalenced neutral false memories are associated with more controlled processing.
