Despite the abundance of research on attachment and on the effects of separation, very little research examines the actual processes of separation occurring daily when mothers leave their children (age 6-18 months) in out-of-home group care. In the current study, this everyday process of separation was observed for three months…

Is infant looking behavior in ambiguous situations best described in terms of information seeking (social referencing) or as attachment behavior? Twelve-month-old infants were assigned to 1 of 2 conditions (Study 1); each infant's mother provided positive information about an ambiguous toy and an experimenter provided positive information. In…

Thirty-eight infants at age one were seen with their mothers in a strange situation test. On the basis of reunion behavior in this situation, each infant was rated for security of attachment to the mother. Maternal behaviors were observed in a mother-child free-play setting when the infants were 21 months old. (JMB)

The consistency of eight attachment behaviors across a four-month period was investigated in two samples of infants. Multiple correlations revealed significant amounts of consistency in attachment behavior for vocalizing, visual regard, proximity to the mother from 10 to 14 months, and for touching and proximity to her from 14 to 18 months. (SE)

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…

Investigates whether, and under what conditions, mothers of irritable infants, in contrast to mothers of less irritable babies, become less responsive/sensitive over time. (HOD)

Presents a developmental study of changes in infant attachment behaviors. Five groups of female infants, 8, 11, 14, 19, and 24 months of age, were observed during varying types of separation experiences. Changes in proximity behaviors and contact behaviors were analyzed. (BD)

Investigates factors associated with outcomes in attachment relationships between 30 well-educated, full-time working mothers and their 18-month-old firstborn sons. Suggests maternal employment effects on mother-son attachment are mediated primarily by a woman's affective state, which becomes manifested in her style of caregiving and child-care…

Using the Ainsworth Strange Situation Procedure, a study examined the interrelations between dimensions of emotion and social interactive behaviors to explore the regulatory role of each in mother-infant interaction and how these roles may change in the second year. (HOD)

Research on characteristics of Down Syndrome infants affecting the interaction between mother and child is reviewed. Differences in the development of the social communication behaviors of state control (sleep and awake); gaze patterns; coordination of gesture, gaze, and vocalization; and frequency of vocalization have implications for parental…

Examines the validity of a maternal rating scale for pacifier-attachment in a laboratory setting. Once mothers' abilities to assess their children's attachment behavior were ascertained, a second study was designed to contrast the patterns of attachment to pacifiers, blankets, and hard objects in children between 1.5 and 63 months. (Author/MP)

Despite recent widespread claims about the importance of early contact for facilitating mother-infant bonding, the effects of early contact have not been convincingly demonstrated. Methodological and procedural difficulties, contributing to a "Hawthorne" effect, may account for the pattern of inconsistent and unclear findings to date.…
