Hypothesizes that infants with attentive mothers will interact more positively with consistent partners than with matched strangers. Finds that when mothers were attentive infant dyads composed of consistent partners interacted more than stranger dyads. Suggest that withdrawal of maternal attention may be equivalent to physical separation by a…

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)

Demonstrates that eye contact per se, and not solely the inherent attractiveness of the eyes and face, is salient to five-month-old infants. Five-month-old infants can distinguish when another person is looking at them, rather than at a nearby location. (Author/MP)

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)

The attachment behavior of 35 white, middle-class 3 1/2- to 4-year-olds who had experienced different rearing histories was observed through a series of standardized episodes involving separations and reunions with the mother and a stranger. (Author/JMB)

This study compares the face-to-face interaction of infants with fathers to their interaction with mothers and with strangers. Five infants were videotaped in individual interaction with their mothers, fathers, and unfamiliar adults at weekly intervals from the second week until the infants were 6 months old. Infants were seated in a laboratory…

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,…

The Ainsworth-Wittig strange situation was used to compare 12 42-month-old children with approximately 6 months of day care experience to individually matched children who had not had group child rearing experience. Results did not support the idea that day-care experience impairs attachment to the mother. (JMB)

This study was designed to compare the inter-/intra-correlational and the behavioral commonalities approaches to the assessment of attachment behaviors of infants to their mothers. At 7 months, 147 infants were observed (and videotaped) sequentially during a free play period with their mothers present, a separation from their mothers and then a…

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 study of the bidirectional effects of parent-child relations, focuses on the exchange of attachment behaviors, investigating the interactions of twelve 3-member nuclear families in a strange-situation condition. Dyadic and triadic conditions involving parents with their 12-, 18-, or 24-month-old children were observed and videotaped in a…

This longitudinal study investigated mother-infant interaction patterns and infant social and emotional development as influenced by maternal and non-maternal infant care and by selected maternal and infant characteristics. Extensive data (including maternal attitude scores, demographic infomration, infant care observations, developmental test…
