Abstract：
Both parasympathetic nervous system regulation and receipt of social support from close relationships contribute to prosocial development, although few studies have examined their combined influences in adolescence and particularly within racially and ethnically minoritized populations. In this longitudinal study of 229 U.S. Mexican-origin adolescents (48% female-identifying), youths reported on receipt of social support from family and friends from 10 to 16 years, had their baseline respiratory sinus arrhythmia (RSA) measured at 17 years, reported their prosocial behavior and completed the Mind in the Eyes test to assess cognitive empathy at 17 and 19 years, and reported their prosocial civic behavior (i.e., community activity) at 19 years. Family social support predicted prosocial behavior at 17 years, and friend social support predicted prosocial civic behavior at 19 years. Compared to youths with lower or higher baseline RSA, youths with moderate RSA reported more prosocial civic behavior, had greater cognitive empathy, and tended to report more general prosocial behavior at 19 years. The quadratic association between baseline RSA and cognitive empathy was stronger for youths with greater family social support. These findings are the first to extend the evidence that moderate baseline parasympathetic nervous system activity supports prosocial development into late adolescence and with the U.S. Mexican-origin community, and these findings address calls for more integrative biopsychosocial studies of prosociality.

摘要：
副交感神经系统调节和从亲密关系中获得社会支持都有助于亲社会发展，尽管很少有研究研究它们在青春期，特别是在种族和少数民族人群中的综合影响。在这项针对229名美国墨西哥裔青少年的纵向研究中(48%为女性认同)，据报道，10至16岁的年轻人接受了家人和朋友的社会支持，他们在17岁时测量了基线呼吸性窦性心律失常(RSA)，报告了他们的亲社会行为，并完成了“眼睛中的心灵”测试，以评估17岁和19岁时的认知移情，并报告了他们的亲社会公民行为(即，社区活动)在19岁。家庭社会支持预测17岁时的亲社会行为，朋友社会支持预测了19岁时的亲社会公民行为。与基线RSA较低或较高的年轻人相比，中度RSA的年轻人报告了更多的亲社会公民行为，有更大的认知同理心，并倾向于在19岁时报告更一般的亲社会行为。对于具有更大家庭社会支持的年轻人，基线RSA与认知移情之间的二次关联更强。这些发现是第一个将适度的基线副交感神经系统活动支持青春期后期和美国墨西哥裔社区的亲社会发展的证据。这些发现解决了对亲社会的更综合的生物心理社会研究的呼吁。（PsycInfo数据库记录（c）2024APA，保留所有权利)。
