Background: Individuals with Angelman syndrome appear strongly motivated by social contact, but there have been few studies that have examined the relationship between sociability and familiarity. In this study we compared social behaviour in Angelman syndrome when in contact with mothers and strangers. Methods: We systematically manipulated adult…

Characteristic patterns of infant-parent relationships were examined in a sample of Black infants presumed to be at low risk for psychopathological development. Infant responses toward parents and a stranger in a structured laboratory play session were analyzed to determine normative patterns of Black infant-parent attachments. Infant exploratory…

Critically evaluates knowledge about relations between early interaction, the "strange situation," and later social behavior in normal and atypical infants including premature infants, abused or neglected infants, and the infants of depressed mothers. Attributes equivocal relations between early interaction behaviors and later attachment…

Social behaviors of 10- and 12-month-old infants were studied as a function of experimental context (home and laboratory) and experimental history (home rearing and day care). Results suggested that the experimental context influenced infant social behaviors. No differences attributable to rearing condition as a main effect were found. (Author/SB)

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)

A total of 87 infants 10 months of age received, either directly or indirectly, a positive nonverbal message, a neutral nonverbal message, or no message about a stranger. Infants, especially those with easy temperaments, were friendlier to the stranger when mothers had spoken positively, but only when the message was directly communicated.…

Forty middle-class mothers and their 12-month-old infants participated in an examination of the extent to which infant sociability and home experiences were correlated with cognitive capacity. (JMB)

This study examined infants' reactions to new people by manipulating the social context in which infants became acquainted with new people. Infants (N=48) met someone new in the presence of another unfamiliar adult and their mothers. The new acquaintance either: (1) chatted and worked on a puzzle with the mother; (2) remained silent and worked on…

This paper reports an 18-month investigation of the differential effects of social context (i.e., characteristics of people in the child's immediate environment) on infants' positive social behavior. The social behaviors of 14 children from 1 to 2-1/2 years of age were observed at home and in a laboratory playroom. The social context was varied…

This study investigated at the age at which infants become able to discriminate between their mothers and females strangers, as measured by differential patterns of pauses during the infants' crying while being spoken to by their mothers and female strangers. The subjects, 14 infants ranging in age from 7 to 20 days, were fed, burped, and changed,…

Discusses observations of sets of infant twins, aged 6 to 24 months, as they interacted with one another and with an unfamiliar peer. Assesses quality of infant-mother attachment. Finds twins are more likely to react with one another than with a peer. Results are discussed in relation to early peer relationships and attachment. (Author/RWB)

Six infants were filmed at 15 and 30 weeks of age while alone and in the presence of an adult (mother or stranger) who interacted with the infant or remained passive. Signal detection analysis of ratings made by judges showed that infant behavior at both ages varied in accord with whether or not an adult was present. (Author/DB)

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)
