Examined whether an infant's reaction to a stranger would be indirectly influenced by the infant observing a stranger-third party interaction. Subjects were 45 15-month-old infants. Results suggest indirect effects influence social interactions and show that significant others can play an important role in mediating these effects. (Author/RH)

Twenty infants were observed at home interacting with their mothers, fathers, and an unfamiliar investigator when they were 15, 18, 21, and 24 months of age. (Author/JMB)

Investigated the autonomic reactions (heart rate and skin conductance) of 17 mothers of five-month-old infants to two landscape scenes and four types of videotaped segments depicting their own baby and an unfamiliar baby smiling or crying. (JMB)

Infants were classified as high or low in differential vocal responsiveness (DVR), and tested for degree of response to stimulation by a stranger and to stimulation by their mothers. The infants' DVR classification was related to scores on the Stanford-Binet and the Illinois Test of Psycholinguistic Abilities. (Author/SS)

A twin analysis was applied to infants' social behavior in standardized situations that permitted the comparison of social responding to mother and a stranger in different contexts. Twenty-one identical twin pairs and twenty-five fraternal twin pairs were observed in their homes using time-sampled observations of specific behaviors. (Author/SS)

No differences were found between home-care and day-care 4- and 5-year-olds on dependency measures. However, home-care girls sought proximity toward their mothers significantly more often than home-care boys, while day-care girls did not differ from day-care boys. This suggests that day-care children may be less sex typed than home-care children.…

Examined home-reared and institutionalized infants in Greece to find sex differences in social-vocal behaviors as assessed by Differential Vocal Responsiveness (DVR) to mother/caretaker versus stranger interactions. Results suggest that early differences in vocal-interactional patterns, and possibly cognitive processing, may be attributable to…

Examines the relation between dyadic synchrony and child compliance during the toddler period. Demonstrates that children are more likely to comply with synchronous caregiver instructions than with asynchronous instructions. Discusses results in light of both cognitive and emotional factors of toddlers. (Author/RWB)

Examines the strange-situation procedure among Japanese mother-infant pairs and analyzes their behavior by comparing them with the data reported in the book by M.S. Ainsworth and others. (HOD)

Twenty 18-month-olds were observed interacting with their mothers and fathers in a structured laboratory setting. Assessed were affiliation and attachment behaviors when the infant was alone with either the mother or father or with both parents and when stranger entered. (Author/MS)
