Previous studies on intentional and incidental face memory have investigated the effects of emotional facial expression on facial recognition itself. However, it is still uncertain whether facial expression influences later recognition of other emotional stimuli, such as emotional scenes. To address this issue, participants during the encoding phase were presented with emotional scenes together with facial expressions. The emotion of the scenes was either congruent or incongruent with that of the facial expression. In order to increase the attention towards faces/facial expressions, the task was related to faces rather than scenes, for example, the participants were asked either to memorize the facial identities (intentional face learning, Experiment 1) or to identify the gender of the faces (incidental face learning, Experiment 2). Subsequently, the participants were asked to perform an unexpected old/new recognition task regarding the scene pictures. In general, the results showed that recognition of threat-related scenes was enhanced by a preceding emotionally incongruent facial expression irrespective of intentional or incidental face learning. The findings indicate that facial expression influences recognition of contextual threat-related scenes.

通过在情感上不一致的面部表情之前增强对上下文威胁相关场景的识别

先前对有意和偶然面部记忆的研究调查了情绪面部表情对面部识别本身的影响。然而，面部表情是否会影响对其他情绪刺激的后续识别，如情绪场景，目前尚不确定。为了解决这个问题，在编码阶段向参与者展示了情感场景和面部表情。场景的情绪与面部表情的情绪或一致或不一致。为了增加对面部/面部表情的关注，任务与面部而非场景相关，例如，要求参与者记住面部身份（故意面部学习，实验 1）或识别性别人脸（附带人脸学习，实验 2）。随后，参与者被要求对场景图片执行一项意想不到的旧/新识别任务。总的来说，结果表明，无论是有意还是无意的面部学习，先前情绪不一致的面部表情都会增强对威胁相关场景的识别。研究结果表明，面部表情会影响对上下文威胁相关场景的识别。
