ABSTRACT

Research reveals that long-term memory guides attention. However, it remains unclear how it interacts with emotional arousal to guide attention. To address this issue, we asked participants to learn the locations of a target key embedded within scenes (i.e. a training phase). On the next day, participants’ arousal was manipulated by presenting with a previously fear-conditioned tone (CS+) or a neutral tone that had not been paired with electrical stimulation (CS−), followed by the brief presentation of a scene from the training phase. Participants indicated whether the scene included the target key. The target was presented at the same location as in the training phase. Results revealed that CS+, compared with CS−, led to faster target detection, suggesting that arousal induced by CS+ enhanced the effects of long-term memory in guiding attention. These findings support our hypothesis: Arousal amplifies the effects of priority in visual search due to long-term memory.

摘要

研究表明，长期记忆可引导注意力。但是，尚不清楚它如何与情绪唤醒相互作用以引导注意力。为了解决这个问题，我们要求参与者学习嵌入场景中的目标键的位置（即训练阶段）。第二天，通过呈现先前恐惧条件的音调（CS +）或未与电刺激配对的中性音调（CS-）来操纵参与者的唤醒，然后简短地介绍训练中的场景阶段。与会者指出场景是否包含目标关键点。在训练阶段将目标显示在相同的位置。结果表明，与CS-相比，CS +导致更快的目标检测，表明CS +引起的唤醒增强了长期记忆在引导注意力方面的作用。
