Twenty matched mother-infant dyads were studied one, two, and three months after expected date of birth. Full-term infants were more active than pre-terms at four weeks, and their interactions were related to maternal experiences. Mothers of pre-terms showed differences in their interactions at all times. Degree of neonatal illness was correlated…

This study examined the functions of structured modeling and mother-child play settings upon the development of pretend actions in young Down Syndrome children. Subjects were 30 pairs of Japanese children, with a developmental age range of 12-35 months, and their mothers. The children were individually administered five phases of premodeling,…

In this study of prominent characteristics of parenting in the United States, France, and Japan, 72 mother-infant dyads were examined. The study focused on three prominent interactive domains of visual and vocal exchange between mother and baby (nurturing, social exchange, and didactic stimulation), examining their frequency of occurrence and…

Tested a proposed developmental pathway for toddlers' mastery of skills in generating non-ritualized forms of cooperative coordinated action with peers. Studied nonverbal imitative acts among U.S. toddlers and toddlers of the Seltaman people of Papua New Guinea. Found that ready imitation of one another emerged during the same developmental period…

This paper describes the ongoing action research program at a residential school for students with emotional and behavior disorders in England.
