In this thesis a study is made of the organisation and biological significance of the smiling response in early hu~an infancy. It is based in part on the results of previous empirical studies of smiling, the relevant evidence from which is syste~atizedanj critically exacined, and in part on exploratory experiments carried out by the writer in a pilot study of infants in the first eight months of life. The mode of development of the response over this period is examined, taking account of the detailed variations in its characteristics as it occurs in association with other behaviour in various types of situation. The changing nature of the external and internal factors that control it is traced. The trenJ of increasing limitation of occurrence of the response to situations of social interaction, first with other people in general and then with particular individuals, especially the @other-figure, is elaborated. In relation to this trend the effects of processes of hlaturation and learning on the development of the mechanism that subservos the response arc considered. Viewing the trend in the perspective of evidence from stUdies of the development of early social relations in a variety of classes of animal, the role of the response as a means of social communication, and its biological function in contributing to the development of the infant's attachment to his mother ~re worked out. This function is further elaborated by consideration of the descriptive, causal and functional relations of smiling both with the responses of laughing and crying and with homologous responses at other primate levels. Such comparative study leads also to a hypothesis about the derivation of smiling as a greeting response from smiling as low-intensity laughing. The ontogeny of the greeting response is seen as the natural outcome of trends discerned in the evolution of the infant mother relationship.
