Bruner's (1973) review of infant skill development is updated and extended by (a) placing it in the context of recent motor learning research; (b) discussing the concept of efference in its most recent conceptualization; and (c) explicating certain implicit themes relevant to a theory of infant motor intelligence.

Used weekly-obtained longitudinal observational data of infant crying, fretting/fussing, and smiling and the time spent in physical contact with mother to examine behavioral variability over a 15-month period. Found evidence of an important intraindividual variability between newborn and 5 months, and 5 and 10 months, but not between 10 and 15…

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…

Examined effect of familiarization on 3.5-month-olds' retention of visual stimuli with varying delay times. Found support for retention models in which direction of attentional preferences (novel, familiar, or null) depends on memory accessibility. Short lookers showed better retention over time than long lookers, indicating that much of the…

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…

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…

It is difficult to make progress in the study of emotions and emotional development if the meanings assigned to central constructs vary widely across investigators. This book clarifies and synthesizes the different ways in which emotion researchers approach fundamental questions about the nature of emotion and emotional development. Theorist and…

A study of the advantages and disadvantages of various types of infant care provided by someone other than the mother is presented. Problems listed as occurring in intervention programs include: maternal-child attachment, individual differences among infants, planning problems, and emotional-social development. Types of intervention studied are:…
