Peer relations during adolescence contribute significantly to the development of socio-cognitive skills and pro-sociality. The current study probed the characteristics of adolescent socio-cognitive processing through a card game where they earn money for self and friend. We investigated the choice preference and temporal dynamics of information processing by measuring ERP responses to wins or losses (valence) directed toward self and friend (recipient). Choice data showed that despite adults and adolescents earning equivalent amounts across recipients combined, adults won significantly more for self than a friend; no such difference was found in adolescents. The ERPs in response to choice outcomes showed that the valence information was processed earlier (at P2) in adults, while it was processed later (at P3) in adolescents. Furthermore, a strong effect of recipient was present in adults later in the time course (at P3), while such an effect was weak in adolescents; if any, adolescents showed sensitivity to recipient information earlier at P2. These ERP data suggest a relatively equal allocation of the P3-mediated attentional process to both self and friend's outcomes in adolescents, which parallels the choice behavior. Collectively our results characterize adolescent pro-sociality toward friends, reflecting the importance of peer relationship during this unique developmental period.

为我赚钱和为朋友赚钱：针对青少年和成年人的社会奖励处理的ERP研究。

青春期的同伴关系极大地促进了社会认知能力和亲社会性的发展。当前的研究通过纸牌游戏探讨了青少年社会认知处理的特征，他们通过这种游戏为自己和朋友赚钱。我们通过测量针对自身和朋友（接收者）的成败（效价）ERP响应，研究了信息处理的选择偏好和时间动态。选择数据显示，尽管成年人和青少年在受助者上的总收入相等，但成年人的自我赢得远胜于朋友。在青少年中没有发现这种差异。响应选择结果的ERP显示，成人价价信息处理较早（P2），而青少年则较晚处理（P3）。此外，在接受治疗的成人中，接受治疗者的强烈反应在时间过程的后期（P3）出现，而在青少年中这种作用较弱；如果有的话，青少年在P2之前对接收者信息表现出敏感性。这些ERP数据表明，P3介导的注意力过程相对于青少年自身和朋友的结局分配相对均等，这与选择行为相似。我们的研究结果总体上体现了青少年对朋友的亲社会性，反映了在这个独特的发展时期同伴关系的重要性。这些ERP数据表明，P3介导的注意力过程相对于青少年自身和朋友的结局分配相对均等，这与选择行为相似。我们的研究结果总体上体现了青少年对朋友的亲社会性，反映了在这个独特的发展时期同伴关系的重要性。这些ERP数据表明，P3介导的注意力过程相对于青少年自身和朋友的结局分配相对均等，这与选择行为相似。我们的研究结果总体上体现了青少年对朋友的亲社会性，反映了在这个独特的发展时期同伴关系的重要性。
