第三方干预对亲社会行为的影响:一项三水平元分析
The effects of third-party intervention on prosocial behavior:A three-level meta-analysis
摘要
Abstract
As an important force in maintaining social norms,third-party intervention has attracted widespread attention from researchers for its potential to promote prosocial behavior.To systematically examine the strength of this prosocial effect and its influencing factors,this study employed a three-level meta-analytic approach,synthesizing 130 effect sizes from 40 empirical studies involving a total of 10,289 participants.Main effect analyses revealed that third-party intervention has a moderately strong positive effect on prosocial behavior.Moderator analyses indicated that greater intensity and higher probability of third-party intervention were associate with stronger prosocial effects,whereas no significant moderating effects were observed for age,gender,intervention type,form,agent,cost,prosocial behavior measurement paradigm,or control group setting.These findings provide robust evidence for the positive impact of third-party intervention on prosocial behavior and clarify key moderating factors,offering valuable insights for future theoretical and experimental research.关键词
