Six studies (two pre-registered, total N = 1861) examined whether individuals would be more likely to give advice to close rather than non-close others against engaging in prosocial behaviours. The results consistently showed that participants were less inclined to advise close (vs. non-close) others to donate blood (Studies 2 and 3), to donate money (Study 5) and to engage in volunteer activities (Studies 1–6). Moreover, Studies 3, 5 and 6 also provided evidence suggesting that prosocial advice given to close others was more contingent on cost judgements than that given to non-close others. These findings have significant implications for the understanding of social influences on prosocial behaviours.

亲社会建议关闭与非关闭他人

六项研究（两项预先注册，总共N  = 1861）检查了个人是否更有可能向亲社会而不是非亲近的他人提供建议以反对参与亲社会行为。结果一致表明，参与者不太倾向于建议亲近（与非亲近）其他人献血（研究 2 和 3）、捐款（研究 5）和参与志愿者活动（研究 1-6）。此外，研究 3、5 和 6 还提供了证据，表明给予亲密他人的亲社会建议比给予非亲密他人的更取决于成本判断。这些发现对于理解社会对亲社会行为的影响具有重要意义。
