Abstract

Abstract: Using the “false survey report” paradigm, this study conducted two experiments to examine how different levels and types of protective behavioral norms influence junior high school students’ protection willingness to act as bystanders in school bullying, as well as the mediating role of self-determined motivation in this relationship. The results showed that: 1) high levels of both descriptive and injunctive protective behavior norms significantly enhanced bystanders’ protection willingness; 2) introjected motivation mediated the effect of both high descriptive and high injunctive protective behavior norms on bystanders’ protection willingness; 3) autonomous motivation mediated the relationship between high injunctive norms and bystanders’ protection willingness. In summary, high descriptive and injunctive protective norms not only directly increase the junior high school student-bystanders’ protection willingness in school bullying but also indirectly enhance it by stimulating introjected motivation.

Key words: school bullying, bystander protection willingness, protective behavior norms, normative focus theory, self-determined motivation

摘要： 研究采用“虚假调查报告”范式，通过两个实验考察不同水平和不同类型的保护行为规范对初中生校园欺凌旁观者保护意愿的影响，以及自我决定动机在这一路径中的中介作用。研究发现：(1)高描述性和高命令性保护行为规范可以显著提高初中生校园欺凌旁观者的保护意愿；(2)内摄动机在高描述性和高命令性保护行为规范影响初中生校园欺凌旁观者保护意愿的过程中均起中介作用；(3)自主动机在高命令性保护行为规范影响初中生校园欺凌旁观者的保护意愿过程中起中介作用。高水平的描述性与命令性保护行为规范能直接提高以及通过激发内摄动机间接提高初中生校园欺凌旁观者的保护意愿。
