Abstract：
Aggression is one of the public social issues affecting campus harmony and stability, and social exclusion is an important interpersonal contextual factor among many factors affecting aggression. However, studies examining the influence of social exclusion on aggression and its mediating mechanism are not systematic enough. Based on the general aggression model (GAM), we intend to explore the role of hostile attribution bias (HAB) in both trait and state levels of social exclusion, which leads to aggression through a combination of questionnaire and experimental methods. Study 1 surveyed 388 current high school students (Mage = 16.09, SD = 1.01) and found that HAB mediates the relationship between long-term social exclusion (trait level) and aggression tendency. Study 2 experimented with 181 high school students (Mage = 16.95, SD = 1.13) to examine whether short-term social exclusion (state level) after initiating the Cyberball paradigm could still influence aggressive behavior through the mediating role of HAB. Results found that the mediating role of HAB still holds. The findings of the study further enrich the GAM and have important implications for a more targeted approach to aggression prevention and intervention.
摘要：
侵略是影响校园和谐稳定的公共社会问题之一,社会排斥是影响侵略的众多因素中重要的人际背景因素。然而,研究社会排斥对侵略的影响及其中介机制的研究还不够系统。基于一般侵略模型(GAM)，我们打算探讨敌意归因偏见(HAB)在特质和国家层面的社会排斥中的作用，通过问卷调查和实验相结合的方法导致侵略。研究1调查了388名当前高中生（Mage=16.09，SD=1.01），发现HAB介导了长期社会排斥（特质水平）与侵略倾向之间的关系。研究2对181名高中生（Mage=16.95，SD=1.13）进行了实验，以检查启动Cyberball范式后的短期社会排斥（州水平）是否仍然可以通过HAB的中介作用影响攻击行为。结果发现，HAB的中介作用仍然有效。该研究的发现进一步丰富了GAM，并对更有针对性的侵略预防和干预方法具有重要意义。
