Co-speech hand gestures offer a rich avenue for research into studying emotion communication because they serve as both prominent expressive bodily cues and an integral part of language. Despite such a strategic relevance, gesture-speech integration and interaction have received less research focus on its emotional function compared to its cognitive function. This review aims to shed light on the current state of the field regarding the interplay between co-speech hand gestures and emotions, focusing specifically on the role of gestures in expressing and understanding both others’ and one's own emotions. The article concludes by addressing current limitations in the field and proposing future directions for researchers investigating gesture-emotion interaction. Our goal is to provide a roadmap to researchers in their exploration of the role of gestures in emotions, ultimately contributing to a more comprehensive understanding of how gestures and emotions intersect.

通过共同言语手势探索情绪：注意事项和新方向


共同言语手势为研究情感交流提供了丰富的途径，因为它们既是突出的身体表达线索，又是语言的组成部分。尽管具有如此的战略相关性，但与认知功能相比，手势-语音整合和交互的情感功能研究较少。这篇综述旨在阐明共同言语手势与情感之间相互作用的领域现状，特别关注手势在表达和理解他人和自己的情感中的作用。文章最后解决了该领域当前的局限性，并为研究手势情绪交互的研究人员提出了未来的方向。我们的目标是为研究人员探索手势在情感中的作用提供一个路线图，最终有助于更全面地理解手势和情感如何交叉。
