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…

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…

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)

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)

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.

This study applied Meehl's taxometric techniques for distinguishing latent types from late continua to Strange Situation data on 1,139 fifteen-month-olds from the NICHD Study of Early Child Care. Results indicated that variation in attachment patterns was largely continuous, not categorical. Implications of dimensional models for individual…

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)

Advocates renewed efforts toward assessing attachment on a single continuum of emotional security. Contends that theory is essential to guide attachment assessment and that the constructs of secure base and emotional security provide the needed conceptual foundation. Addresses challenges to the scoring of attachment on a security continuum.…

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…

Examined were differences in attachment behaviors of 14 abused and seven nonabused infants. Videotapes were taken during brief separation and reunion from their mothers and a habituated nonfamiliar figure. Ratings were made of exploration, distress, head turning, following, crying with separation, soothing, positive greeting, differential…
