Genetics and the development of social behavior in mammals.

Abstract

This paper summarizes recent work on the development of social behavior in animals, together with some evaluation of the results in relation to human problems. Social development results in the formation of social relationships, and the time when the first social attachments are formed is a critical period in determining the nature of these and future relationships. Heredity produces important differences in development both within and between species. The course of social development in any one species is directly related to the normal type of social organization found in the species. Consequently, either deviations from normal development or gross alterations of social organization should produce maladjustment. Basic social needs of human infants are discussed in the light of these concepts.
