Infants learn from adults readily and cooperate with them spontaneously, but how do they select culturally appropriate teachers and collaborators? Building on evidence that children demonstrate social preferences for speakers of their native language, Experiment 1 presented 10-month-old infants with videotaped events in which a native and a foreign speaker introduced two different toys. When given a chance to choose between real exemplars of the objects, infants preferentially chose the toy modeled by the native speaker. In Experiment 2, 2.5-year-old children were presented with the same videotaped native and foreign speakers and played a game in which they could offer an object to one of two individuals. Children reliably gave to the native speaker. Together, the results suggest that infants and young children are selective social learners and cooperators and that language provides one basis for this selectivity.

“母语”对象和合作者：婴儿的对象选择和给予行为反映了对母语者的偏爱而不是外国说话者

婴儿很容易向成年人学习并自发地与他们合作，但他们如何选择适合文化的教师和合作者？基于儿童表现出对母语使用者的社会偏好的证据，实验 1 向 10 个月大的婴儿展示了录像事件，其中母语者和外语者介绍了两种不同的玩具。当有机会在物体的真实样本之间进行选择时，婴儿优先选择由母语人士建模的玩具。在实验 2 中，2.5 岁的儿童被呈现给相同的母语和外国说话者的录像带，并玩了一个游戏，他们可以向两个人中的一个人提供一个物体。孩子们可靠地给予母语者。一起，
