Abstract

We review evidence that, from birth, infants have purposeful consciousness of rhythmic whole‐body movement, with multi‐modal perception of objects outside their body, and self‐related emotional appraisal of experiences. Newborns also exhibit a special human awareness of the vitality of company in actions and feelings, and a capacity to use imitation of action signs for dialogic exchange of intentions. These abilities are prepared by specific systems of body and brain that develop before birth. Through the first two years, a baby shows age‐related advances with growth of motor powers in use of intersubjective play and object awareness. These developments are adapted for life‐time learning how to identify and share meaningful conventions of a culture, and the description of experiences in words of a living language. Teaching is stimulated and assimilated by the affections, playful humor, and imaginative curiosity of the child in the company of people they know well.
