Examines the ability of infants at various age levels between three and nine months to discriminate between their mother and a stranger, and relates such ability to the infants' developmental quotient at age nine months. (Author/MP)

Two-year-olds' reactions to strangers were related to ratings of their emotionality, sociability and activity and to ratings of parental love and control by both fathers and mothers. Each child received two sessions with strangers, one male and one female. Four times per session a stranger, in a friendly manner, approached each child as it sat in…

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)

A total of 134 mothers and their newborn infants were studied in order to evaluate the relationship between neonatal characteristics and mother-infant interaction. (SB)

This study identifies elements in the attachment behaviors of 7-month infants which predict the quality of their attachment to their mothers at 13 months. At 7 months 147 infants were observed (and videotaped) during a free play period with their mothers present, during a separation from their mothers and then during a reunion period. At 13 months…

This paper presents an overview of the literature on mother-infant attachment behavior. Attachment is defined by Ainsworth as involving affection, discrimination, observable behavior, active participation by both parties, and reciprocal response. The process of attachment is seen by Stone, Smith, and Murphy as taking place in three stages over the…

The impact of two levels of infant organization and marital satisfaction on parent-infant interaction patterns was investigated in 25 couples. It was predicted that (1) disorganized infants would have a negative impact on the parent-infant relationship, and that (2) parent-infant interaction with disorganized infants would be more negative among…

Presents a study of the early home experiences of a group of 2-week-old infants, equally divided according to social class, birth order and sex. (JMB)

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…

The purpose of this study was to investigate whether or not infants who had experienced different types of naturally-occurring, significant separations from an attachment figure during the first year of life differed in their response to separation at 12 months of age. Thirty-three 12-month-old Caucasian infants from middle class, intact families…

Gazing behavior of 10 twin infants (five male and five female) and their mothers were recorded weekly during the babies' fourth month of life. Videotape equipment was used in the home; data were gathered as naturalistically as possible. (Author/MS)

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…
