This target article presents a theory of human cultural learning. Cultural learning is identified with those instances of social learning in which intersubjectivity or perspective-taking plays a vital role, both in the original learning process and in the resulting cognitive product. Cultural learning manifests itself in three forms during human ontogeny: imitative learning, instructed learning, and collaborative learning – in that order. Evidence is provided that this progression arises from the developmental ordering of the underlying social-cognitive concepts and processes involved. (...) Imitative learning relies on a concept of intentional agent and involves simple perspective-taking. Instructed learning relies on a concept of mental agent and involves alternating/coordinated perspective-taking (intersubjectivity). Collaborative learning relies on a concept of reflective agent and involves integrated perspective-taking (reflective intersubjectivity). A comparison of normal children, autistic children and wild and enculturated chimpanzees provides further evidence for these correlations between social cognition and cultural learning. Cultural learning is a uniquely human form of social learning that allows for a fidelity of transmission of behaviors and information among conspecifics not possible in other forms of social learning, thereby providing the psychological basis for cultural evolution.

!Kung San (Bushman) hunter-gatherers have unusually high levels of mother-infant contact and represent one of the environments of human evolutionary adaptedness (EEAs). Studies among the !Kung show that levels of crying—the most basic sign of mammalian infant distress—are low, and response to crying is high, and some suggest that responses are overwhelmingly maternal. We show that although !Kung mothers respond to crying most often, one-third of crying bouts are managed solely by someone else. Mothers responded to all bouts lasting ≥30 (...) s, but in half of these responses they were joined by one or more others. Mothers are the most consistent responders, but multiple caregiving is common. The mother is rarely alone when her baby cries; others often substitute or join her in interventions. This social support may facilitate the high levels of maternal responsiveness characteristic of the !Kung, and of hunter-gatherers generally, but it is also consistent with recent theory emphasizing nonmaternal care (allocare) and cooperative breeding.
