The behaviours of infants were observed using home videos, in an attempt to identify social difficulties characteristic of infants with autistic disorder. Three groups of infants were analysed: 15 infants who had later been diagnosed with autism, 15 infants who had a developmental or language delay, and 15 typically developing infants. Social…

In this study of early peer interaction, 32 first born infants (16 boys, 16 girls) were videotaped in pairs at 6, 9 and 12 months. Each 15 minute session consisted of Toys Present (TP) and Toys Absent(TA) conditions counterbalanced across dyads. Three questions were addressed: (1) Are infants as young as 6 months capable of interacting with a…

Compares patterns of friendship in infants, toddlers, and preschool children who attended either a child-care center or a program for emotionally disturbed children. Younger children had fewer and more stable friendships; emotionally disturbed children limited friendships to single partners. Complexity of social interaction increased most within…

Two studies, labeled A and B, were conducted (1) to investigate relationships between early infant and mother behaviors over situations and over time, (2) to explore relationships between maternal experiences and behavior, (3) to compare infant-mother pairs with and without interaction problems, and (4) to compare infant-mother pairs in which…

The purpose of this study was to examine the effect of group size on toddlers' peer interactions and social interactions with mothers. In particular, the study sought to answer the following questions: (1) When both mothers and peers are available to the child, with whom does he/she prefer to play? and (2) Are there differences in the types of…

This study compares interactions between infants and parents to interactions between infants and strangers. Infants from 2 weeks to 6 months of age were taped in face-to-face interactions with unfamiliar male and female adults. Tapes of parent-infant interactions were available from a prior study. Specific infant and adult behaviors were coded and…

A study tracked the developmental and behavioral recovery of infants and preschool children (N=12) who had suffered brain injuries. Significant developmental recovery and behavioral progress occurred during the first 3.5 to 4 months following insult. However, self-stimulatory and atypical rhythmic habit patterns increased as the children passed…

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)

Ten parents of preschoolers with autism and 10 parents of typical preschoolers were given the Detection of Autism by Infant Sociability Interview, which elicits reports on 19 aspects of social engagement characteristics. Findings indicate that infants with autism had marked limitations in both person-to-person and person-person-object social…

This paper describes five experimental studies which explored the influence of fathers' home caregiving and interactional characteristics on their infant's laboratory behavior. Approximately 300 families with children ranging in age from 6 to 24 months were studied. Each infant's reactions were observed as a function of the manipulation of the…

Thirty-three deaf and 33 hearing children were videotaped playing with their hearing mothers at 22 months and 3 years of age. The deaf and hearing dyads differed at 22 months only on communicative competence. In addition, interactions in deaf dyads were mother dominated and less harmonious than in hearing dyads. At 3 years, the deaf children also…

This study investigated the response behavior of nine infants, aged 13-15 weeks, to a recurrent pattern of visual and verbal stimuli presented by their own mothers and by female strangers. The infants were presented with the following 2-minute sequence (repeated 3 times): (1) one-half minute of an unknown female leaning over the crib with a…

This guide for parents discusses social competence in 2-year-old children, drawing upon anecdotal data to provide a sampling of 2-year-old children's social behavior and their parents' child rearing techniques. The data were collected from questionnaires, telephone interviews, and home visits in a 12-month study of the interactions of 86…
