The fight or flight phenomena is of evolutionary origin and responsible for the type of defensive behaviours enacted, when in the face of threat. This review attempts to draw the link between fear and aggression as behavioural motivations for fight or flight defensive behaviours. Hence, this review intends to examine whether fight or flight behavioural responses are the result of fear and aggression. Furthermore, this review investigates whether human biological motion captures the affective states associated with the fight or flight phenomenon. This review also aims to investigate how threat informed emotion and motor systems have the potential to result in empathetic appraisal modulation. This is of interest to this systematic review, as empathetic modulation is crucial to prosocial drive, which has the potential to increase the inclination of alleviating the perceived threat of another. Hence, this review investigates the role of affective computing in capturing the potential outcome of empathy from threat perception. To gain a comprehensive understanding of the affective states and biological motion evoked from threat scenarios, affective computing methods used to capture these behavioural responses are discussed. A systematic review using Google Scholar and Web of Science was conducted as of 2023, and findings were supplemented by bibliographies of key articles. A total of 22 studies were analysed from initial web searches to explore the topics of empathy, threat perception, fight or flight, fear, aggression, and human motion. Relationships between affective states (fear, aggression) and corresponding motor defensive behaviours (fight or flight) were examined within threat scenarios, and whether existing affective computing methods are succinct in capturing these responses, identifying the varying consensus in the literature, challenges, and limitations of existing research.

翻译：“战或逃”现象源于进化，决定了面对威胁时防御行为的表现类型。本综述旨在建立恐惧与攻击作为战或逃防御行为动机之间的联系，进而考察战或逃行为反应是否由恐惧与攻击共同作用所致。此外，本文探究人类生物运动能否捕捉与战或逃现象相关的情感状态，并分析威胁驱动的情绪与运动系统如何可能引发共情评价的调节。共情调节对于亲社会驱动力至关重要，能够增强缓解他人感知威胁的倾向，因此本系统综述重点关注这一机制。为此，本文考察情感计算在捕捉威胁感知可能引发的共情结果中的作用。为全面理解威胁场景所诱发的情感状态与生物运动，本文讨论了用于捕捉这些行为反应的情感计算方法。基于Google Scholar与Web of Science截至2023年的系统检索，并辅以关键文献的参考文献补充，从初始网络检索中分析22项研究，探讨共情、威胁感知、战或逃、恐惧、攻击与人体运动等主题。在威胁场景中考察情感状态（恐惧、攻击）与相应运动防御行为（战或逃）之间的关联，并评估现有情感计算方法能否有效捕捉这些反应，同时识别文献中的共识分歧、现有研究的挑战与局限性。
