To document movement patterns and to examine developmental interrelationships, the ontogeny of rooting, lip, lateral tongue, mouth opening, biting, and Babkin reflexes and the development of emerging chewing behaviors were observed in two normal infants over a period from 1 week to 35 weeks of age.

Examined consistency in behavioral state organization for 30 fetuses and neonates. Assessed heart rate pattern and presence or absence of eye and gross body movements during sleep, finding quiet sleep (QS), active sleep (AS), and indeterminate states in nearly identical proportions. Duration of enclosed QS epochs provided only stable measure of…

Studied 112 preterm infants to determine developmental changes and stability of individual differences. Results indicate significant developmental gains with age, and highly significant individual stability of performance across age. (RJC)

Reviews research on infants classified by Ainsworth's "Strange Situation" assessment as insecure/ambivalent, and examines studies exploring attachment theory beyond infancy. Presents a theoretical discussion of the ways in which patterns of mother and child behaviors associated with the insecure/ambivalent pattern may work together to…

Examined the concordance between mother-infant attachment behavior and patterns of mother-child reunion responses when the children were age six. Found that concordance between four types of attachment status was 82%. Also found a correlation between children's observed social competence at age five and their reunion patterns at age six. (MDM)
