Psychologists have long debated the role of early experience in social and cognitive development. However, traditional approaches to studying this issue are not well positioned to address this debate. The authors present simulations that indicate that the associations between early experiences and later outcomes should approach different…

Longitudinal studies have shown how early developmental contexts contribute significantly to self-development; their influence extends through adulthood, informs sociality, and affects resilience under severe stress. While the importance of sociality in trauma recovery is recognized, the relationship between developmental and posttrauma contexts…

Tested the hypothesis that development of secure attachments is predictable from synchronous, and insecure attachments from asynchronous interactions across the first year. Findings from 30 dyads (10 secure, 10 avoidant, 10 resistant) supported the hypothesis at one and three months, with synchronous interaction observed at significantly,…

Two studies examined the relationship between maternal sensitivity and infant security of attachment in home and hospital contexts. Results are discussed in terms of links between methodology and effect sizes, the generality of links between maternal care and child security, need for research on caregiving in ordinary and emergency situations, and…

According to attachment theory, the quality of care plays a key role in the organization of infants' secure base behavior across contexts and cultures. Yet information about attachment relationships in a variety of cultures is scarce, and questions remain as to whether Ainsworth's conceptualization of early care quality (sensitivity; M. D. S.…

Used meta-analysis to examine premise that the early child-parent bond is reflected in interpersonal relationships across the life span. Found that overall effect size (ES) for child-mother attachment was small to moderate. ESs were similar in studies using Strange Situation and Q-sort methods. ESs were larger for middle childhood and adolescent…
