亲社会行为既受到环境特征的影响，也受到个体特质因素的影响。拒绝敏感特质的本质是对拒绝动机的过分敏感，同时对可能发生的拒绝表现出一系列过度的认知情感反应。拒绝敏感特质高的个体可能采取增加或减少亲社会行为的策略，去降低拒绝情境发生的可能性。目前，关于社会拒绝和亲社会行为的研究多在实验室情境中展开。这些研究通过设置社会排斥范式，来探究个体面临模拟排斥后产生的一系列生理和心理反应。但在日常生活中，社会排斥对个体的影响并不仅仅停留在排斥发生后的短暂时间，而是对个体日后行为、逻辑和情感等产生一系列影响，这是实验室实验无法探究的。以往研究对日常情境中的拒绝敏感特质与亲社会行为关系的研究十分罕见，基于归属需求理论观点，本实验认为归属需求可能是拒绝敏感性影响亲社会行为的重要因素之一。因此，本研究采用线上问卷的方式，探讨日常情境下归属需求、拒绝敏感特质与亲社会行为的关系。通过在线发布广告方式收集有效数据共150人份。其中，女生113名（75.3%），男生37名（24.7%）。绝大多数被试年龄处在18~24之间（85.7%）。结果发现：(1)高拒绝敏感性个体表现出更少的亲社会行为意愿；(2)高拒绝敏感性个体的归属感需求水平相对更低，因而使个体具有更低的亲社会行为意愿；(3)归属感需求在拒绝敏感性和亲社会行为意愿的关系之间起到部分中介作用。

Prosocial behavior is influenced not only by environmental characteristics, but also by individual characteristics. The essence of rejection sensitivity is to be excessively sensitive to rejection motivation, and show a series of excessive cognitive and emotional responses to possible rejection. Individuals with high rejection sensitivity may adopt the strategy of increasing or reducing prosocial behavior to reduce the possibility of rejection situation. At present, the research on rejection sensitivity is mostly carried out in the laboratory situation. These studies set up social exclusion paradigm to explore a series of physiological and psychological reactions after individuals face simulated exclusion. However, in daily life, the impact of social exclusion on individuals does not only stay in the short time after exclusion, but also has a series of effects on individuals' behavior, logic and emotion in the future, which cannot be explored by laboratory experiments. Previous studies on the relationship between rejection sensitivity and prosocial behavior in daily situations are rare. Based on the theory of need to belong, this experiment believes that the need to belong may be one of the important factors that rejection sensitivity affects prosocial behavior willingness. Therefore, this study explored the relationship between need to belong, rejection sensitivity and prosocial behavior willingness in daily situations by means of online questionnaire. Through the internet advertisement, we collected 150 valid questionnaires. Participants consist of 113 females(75.3%) and 37 males(24.7%), and most of them are between 18 and 24 years old(85.7%). The results showed that: (1) high rejection sensitive individuals showed less prosocial behavior willingness; (2) High rejection sensitive individuals have a relatively lower level of need to belong which makes individuals have lower prosocial behavior willingness; (3) The need for need to belong plays a partial mediating role in the relationship between rejection sensitivity and prosocial behavior willingness.
