Abstract

Recent research has shown that infants are more likely to engage with in-group over out-group members. However, it is not known whether infants' learning is influenced by a model's group membership. This study investigated whether 14-month-olds (= 66) selectively imitate and adopt the preferences of in-group versus out-group members. Infants watched an adult tell a story either in their native language (in-group) or a foreign language (out-group). The adult then demonstrated a novel action (imitation task) and chose 1 of 2 objects (preference task). Infants did not show selectivity in the preference task, but they imitated the in-group model more faithfully than the out-group model. This suggests that cultural learning is beginning to be truly cultural by 14 months of age.
