Infant feeding behavior: development in patterns and motivation.

Studies of feeding behaviors in human infants not only provide normative data but also allow analyses of the behavioral regulation. Twenty healthy full-term infants were observed by two examiners and were audiovisually and polygraphically recorded under standard conditions at 2, 10, 18, and 26 weeks of age prior to, during, and after breast- or bottle-feeding. The parameters of sucking, breathing and swallowing significantly changed during the first 6 months of age.

Structure and dynamics of human communication at the beginning of life.

Although the beginning of postpartum social integration and communication has been long viewed as relevant to psychiatric theories, early parent-infant communication has become a matter of scientific investigation only recently. The present survey explains the significance of an approach based upon the general systems theory and explores to what extent the early parent-infant interaction can function as a didactic system to support the development of thought and speech. Evidence of this function has been found in those forms of parental behavior that escape the parent's conscious awareness and control, as exemplified in the vocal communication with presyllabic infants.

Biological basis of social interactions: implications of research for an understanding of behavioural deviance.

Among the infant's initial risks, interactional failures have recently been identified as potential links of vicious circles leading from inconspicuous deviance to severe clinical syndromes. The knowledge of the origins of interactional failure has been insufficient. In this paper a basic explanatory model is presented and two major determinants of successful parent-infant interactions are analysed: the infant's integrative competence and the initial forms of parenting.
