Recent work has cast doubt on whether the strength of motivation (strength of avoidance or approach tendencies) experienced while viewing emotion-eliciting pictures is dissociable from felt valence (negative versus positive). The present study extended this work by testing specific discrete emotions (amusement, anger, awe, desire, sadness). Previous work has proposed separate motivational direction (avoid versus approach) from valence. In Study 1, participants ( = 60) rated the motivational direction or valence they experienced while viewing 100 pictures that each evoked one of the five discrete emotions. We found significant differences between average motivational direction and valence ratings for sadness, anger, and amusement. Critically, underlying these averages, we found that while valence responses were highly consistent, there was large variability in motivational direction, with some people indicating they wanted to approach and others indicating they wanted to avoid while viewing the same picture. Individual differences in motivational direction were largest for sadness, so in Study 2 ( = 100) we tested whether they were predicted by appraisals of the situation (e.g., ratings of how welcome or useful people believed their help would be). The three appraisals tested accounted for 64% of the variance in motivational direction, after which valence made a very small unique contribution. These findings highlight that motivational direction and valence can diverge. Given the variability in individuals' motivational direction responses, future studies designed to assess the effects of motivational direction on cognitive processes need to tailor stimuli for each participant to ensure they activate the intended motivational direction.

最近的研究对观看引发情绪的图片时所体验到的动机强度(回避或趋近倾向的强度)是否与感觉的效价(负面与正面)可分离提出了质疑。本研究通过测试特定的离散情绪(愉快、愤怒、敬畏、欲望、悲伤)扩展了这项工作。先前的研究从动机方向(回避与趋近)和效价两个方面对情绪进行了区分。在研究 1 中,参与者(n=60)对观看 100 张图片时所体验到的动机方向或效价进行了评价,每张图片都能引发五种离散情绪中的一种。我们发现,悲伤、愤怒和愉快的平均动机方向和效价评分之间存在显著差异。关键是,在这些平均值的基础上,我们发现,虽然效价反应高度一致,但动机方向存在很大的可变性,有些人表示他们想趋近,而另一些人则表示他们想回避,而观看的是同一张图片。在观看相同图片时,人们的动机方向差异最大的是悲伤,因此在研究 2(n=100)中,我们测试了这些差异是否可以由对情境的评价来预测(例如,评价人们认为自己的帮助会有多受欢迎或有用)。测试的三个评价因素解释了动机方向变异的 64%,之后效价只做出了很小的独特贡献。这些发现强调了动机方向和效价可能会出现分歧。鉴于个体的动机方向反应存在可变性,未来旨在评估动机方向对认知过程影响的研究需要为每个参与者量身定制刺激,以确保它们能激活预期的动机方向。(PsycInfo 数据库记录(c)2023 APA,保留所有权利)。
