Children (predominantly white and middle class) between 3 and 6 years (M = 55.12 months, N = 145 at Time 1, N = 102 at Time 2) participated in the prosocial choice test at two time points approximately 10 months apart. Children could share with strangers, close friends, nonfriends, and in a control, no recipient condition. Children shared more rewards with friends over time. Age interacted with recipient type such that older children had a higher probability of prosocial allocations toward friends and strangers compared to younger children. Theory of mind (ToM) predicted more prosocial allocations to friends over time, and the youngest children with higher ToM scores showed the largest increase in sharing with friends over time.
儿童(主要为白人和中产阶级)年龄在 3 至 6 岁之间(M=55.12 个月,T1 时 145 名,T2 时 102 名),大约 10 个月后在两个时间点参加亲社会选择测试。孩子们可以与陌生人、亲密朋友、非朋友和控制组(无接受者)分享奖励。随着时间的推移,孩子们与朋友分享的奖励更多。年龄与接受者类型相互作用,即与年幼的孩子相比,年龄较大的孩子更有可能对朋友和陌生人进行亲社会分配。心理理论(ToM)预测随着时间的推移,孩子们会有更多的亲社会分配给朋友,而具有较高 ToM 分数的最小的孩子随着时间的推移,与朋友分享的意愿增加幅度最大。
