Positive and negative affects may bias behavior toward approach to rewards and withdrawal from threat, particularly when the contingencies are ambiguous. The hypothesis was that positive and negative affects would associate predictably with identification of happy, disgusted, or angry expressions that may signal potentially rewarding or aversive social interactions. Healthy volunteers (n=86) completed affect ratings and a facial emotion task that employed morphed continua in which emotional expressions gradually decreased in ambiguity. Relations between mood and intensity thresholds for emotion identification were computed. Anhedonia (low positive affect) predicted thresholds for happy expressions (r=0.24; P=.026) whereas negative affect predicted thresholds for disgust (r=-0.25; P=.022). Even within a normal range of mood, mood predicted emotion identification, supporting constructs of positive and negative affect derived originally from self-report measures.
积极情绪和消极情绪可能会使行为倾向于趋近奖励和远离威胁，尤其是当情况不明确时。研究假设是，积极情绪和消极情绪会与识别快乐、厌恶或愤怒表情有可预测的关联，这些表情可能预示着潜在的奖励性或厌恶性社交互动。健康志愿者（n = 86）完成了情绪评分和一项面部表情任务，该任务采用了渐变连续体，其中情绪表达的模糊性逐渐降低。计算了情绪与情绪识别强度阈值之间的关系。快感缺失（低积极情绪）可预测快乐表情的阈值（r = 0.24；P = 0.026），而消极情绪可预测厌恶表情的阈值（r = -0.25；P = 0.022）。即使在正常情绪范围内，情绪也能预测情绪识别，这支持了最初从自我报告测量中得出的积极情绪和消极情绪的概念。
