[Emergence and development of competence in young children].

Background: The childhood emergence and development of motor behavioural skills is imperfectly understood despite intensive study. This report is of the development of motor skills and social behaviour in young children.

Population And Methods: 17 infants (9 boys and 8 girls) in good health, aged 8 to 11 months at the beginning of the research, were studied.

Alternative child care in France: advances in the study of motor, interactive, and social behaviors of young children in settings allowing them to move freely in a group of peers.

This paper reports new data on the emergence and development from the 9th to 19th month of age of motor, interactive, and social behaviors of 17 children with peers in a milieu that allows the "conquest" of the third dimension of space without limitation of their motor activity. Their motor skills and social behaviors appear more precocious and complex than previously indicated by scientific publications, clinical observations, and developmental scales. 1.
