Results showed that when information about a target individual was presented in two internally consistent blocks which were mutually contradictory, impressions produced by concrete operational adolescents contained a significantly greater proportion of evaluative statements in the same evaluative direction as the first block of information…

Investigated the autonomic reactions (heart rate and skin conductance) of 17 mothers of five-month-old infants to two landscape scenes and four types of videotaped segments depicting their own baby and an unfamiliar baby smiling or crying. (JMB)

Infants were classified as high or low in differential vocal responsiveness (DVR), and tested for degree of response to stimulation by a stranger and to stimulation by their mothers. The infants' DVR classification was related to scores on the Stanford-Binet and the Illinois Test of Psycholinguistic Abilities. (Author/SS)

A twin analysis was applied to infants' social behavior in standardized situations that permitted the comparison of social responding to mother and a stranger in different contexts. Twenty-one identical twin pairs and twenty-five fraternal twin pairs were observed in their homes using time-sampled observations of specific behaviors. (Author/SS)

No differences were found between home-care and day-care 4- and 5-year-olds on dependency measures. However, home-care girls sought proximity toward their mothers significantly more often than home-care boys, while day-care girls did not differ from day-care boys. This suggests that day-care children may be less sex typed than home-care children.…

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 home-reared and institutionalized infants in Greece to find sex differences in social-vocal behaviors as assessed by Differential Vocal Responsiveness (DVR) to mother/caretaker versus stranger interactions. Results suggest that early differences in vocal-interactional patterns, and possibly cognitive processing, may be attributable to…

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.…

Examines the relation between dyadic synchrony and child compliance during the toddler period. Demonstrates that children are more likely to comply with synchronous caregiver instructions than with asynchronous instructions. Discusses results in light of both cognitive and emotional factors of toddlers. (Author/RWB)

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…

A cross-national comparison of infant behavior in the Strange Situation was designed to determine whether preseparation episodes made any difference in attachment classifications and whether infant behavior before separation from mother was the same in different countries. Infants in different countries made similar primary appraisals of the…
