Abstract It is well-understood that biospheric personal values (i.e., finding it important to care about nature and the environment) predict individuals' pro-environmental engagement (i.e., motivations, beliefs, attitudes, actions). Yet, little is known about the potential influence group's biospheric values may have on individuals' pro-environmental engagement. In the current paper we hypothesized that when individuals perceive their group to prioritize biospheric values more strongly, their pro-environmental engagement becomes stronger (H1), and that this relationship is particularly pronounced among individuals who strongly identify with the group (H2) and who do not already strongly endorse biospheric values themselves (H3). Our study among 1711 Americans, who depending on the condition answered questions about either their American or political identity (i.e., liberal or conservative, depending on the respondent's political affiliation), found consistent support for our hypotheses across all groups. Our findings have important implications for theory on values and groups, as well for practice. Discussion provides new avenues for future research and interventions, particularly for how to motivate individuals who are not strongly personally motivated.

他人重视的价值：当感知到的生物圈群体价值观影响个人的环保参与时。

摘要 众所周知，生物圈个人价值观（即发现关心自然和环境很重要）预测个人的环保参与（即动机、信念、态度、行动）。然而，人们对群体的生物圈价值观可能对个人环保参与的潜在影响知之甚少。在目前的论文中，我们假设当个人更强烈地认为他们的团体优先考虑生物圈价值时，他们的亲环境参与会变得更强（H1），并且这种关系在强烈认同该团体的个人（H2）和谁尚未强烈支持生物圈价值本身（H3）。我们对 1711 名美国人的研究，谁根据情况回答了关于他们的美国身份或政治身份（即自由派或保守派，取决于受访者的政治派别）的问题，发现所有群体都一致支持我们的假设。我们的发现对价值和群体的理论以及实践具有重要意义。讨论为未来的研究和干预提供了新的途径，特别是如何激励那些没有强烈个人动机的人。
