This study examined the sex-specific developmental trajectories of sharing behavior in the Dictator Game with an anonymous other, best friend, and disliked peer and associations with peer likeability and peer dislikeability in 1,108 children (50.5% boys) followed annually across grades 2–6 (ages 8–12) of elementary school. Results showed that sharing with an anonymous other and disliked peer remained stable over time. Sharing with a best friend decreased slightly between grades 2 and 5 and then remained stable. Girls consistently shared more with all recipients than boys. Moreover, children who were liked by classmates shared more with a best friend, while disliked children shared less with all recipients. Findings emphasize the importance of considering characteristics of both recipient and actor when studying the development of sharing behavior.

课堂上同伴的喜好以及与朋友和他人分享行为的发展

这项研究调查了1108名儿童（男生占50.5％）在每年2至6年级的学习过程中与其他匿名，最好的朋友和不喜欢的同伴分享在独裁者游戏中分享行为的性别特定发展轨迹， （8至12岁）。结果显示，与匿名的其他不喜欢的同伴共享随时间保持稳定。在2年级和5年级之间，与最好的朋友的分享略有下降，然后保持稳定。与所有接受者相比，女孩始终比男孩拥有更多的分享。此外，同学喜欢的孩子与最好的朋友分享更多，而不喜欢的孩子与所有收件人分享的更少。研究结果强调了在研究分享行为的发展时考虑接受者和演员特征的重要性。
