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)

Associations between mother's models of attachment and mother and child behaviors related to separation were explored in a study of 45 mothers and their 2- to 4-year-old children. Results showed that mother behaviors before and after separation and child reunion behaviors varied according to attachment classification. (SH)

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…

Tested two models of the relationship between a hypothetical attachment mechanism and an incompatible motivation (a tendency to explore) by pitting two levels of attachment motivation against two levels of exploratory motivation among 15- to 18-month-old infants, alternating freely between play with novel toys at one end of the room and visits…

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.…

Highlights usefulness of the categorical approach to measuring infant attachment by reviewing some major advances in the field that have been fostered by that approach. Advances include identification of the disorganized attachment group, development of the concept of conditional behavior strategies, creation of systems for coding attachment…

Ainsworth's system of classifying attachment patterns will not be easily displaced primarily because of difficulties involved in a dimensional approach. Problems include the number of dimensions involved, need to develop reliable scales, and need to describe how behavior changes across age and in the Strange Situation. Only when an alternative…

Examines the strange-situation procedure among Japanese mother-infant pairs and analyzes their behavior by comparing them with the data reported in the book by M.S. Ainsworth and others. (HOD)

Focuses on three questions related to attachment theory: whether it requires distinct patterns of attachment, how taxonomic analysis contributes to understanding individual differences in attachment security, and whether attachment theorists are asking the right questions. Asserts that attachment theory is indifferent to the structure of…

Discusses four questions concerning commentaries on the taxometric analysis of Strange Situation behavior related to: (1) whether the categorical model of attachment facilitates theoretical and empirical innovations; (2) whether and how a continuum of security fits into the two-dimensional model; (3) the role of types and dimensions in…
