Sixty white middle-class infants were seen in the Ainsworth Strange Situation at 12 months of age; 50 of these participants (21 males, 29 females) were recontacted 20 years later and interviewed using the Berkeley Adult Attachment Interview (AAI). The interviewers were blind to the participants' Strange Situation classifications. Overall, 72% (36/50) of the infants received the same secure versus insecure attachment classification in early adulthood (kappa = .44, p < .001). As predicted by attachment theory, negative life events, defined as (1) loss of a parent, (2) parental divorce, (3) life threatening illness of parent or child (e.g. diabetes, cancer, heart attack), (4) parental psychiatric disorder, and (5) physical or sexual abuse by a family member were an important factor in change. Fifty-six percent (10/18) of the infants whose mothers reported negative life events changed attachment classifications from infancy to early adulthood. Only 28% (9/32) participants who reported no such events changed classification (p < .05). These results support Bowlby's hypothesis that individual differences in attachment security can be stable across significant portions of the lifespan and yet remain open to revision in light of experience. The task now is to use a variety of research designs, measurement strategies, and study intervals to clarify the mechanisms underlying stability and change.One of Bowlby's primary goals in developing modern attachment theory was to preserve what he considered Freud's genuine insights about close relationships and development. These included insights about (1) the complexity of social, cognitive, and emotional life in infancy, (2) underlying similarities in the nature of close relationships in infancy and adulthood, and (3) the importance of early experience.In order to preserve these insights, Bowlby recast Freud's insights in terms of control systems and ethological theories. He also placed his own imprint on them, replacing cathectic bonding with evolved secure base patterns as the common thread in infant and adult relationships. He also placed greater emphasis on the openness of early relationships to change, especially in light of real-life experiences.
Irisin is associated with increased risk of MetS, cardiometabolic variables, and CVD in humans, indicating either increased secretion by adipose/muscle tissue and/or a compensatory increase of irisin to overcome an underlying irisin resistance in these subjects.
A focus on the secure base phenomenon creates a framework for exploring the function of the attachment system in adulthood. Engaged couples (N = 157) were videotaped in a problem-solving interaction and assessed using the Secure Base Scoring System (SBSS), a system based on Ainsworth's analyses of infant-parent secure base use and support. Study 1 showed behavior was significantly related to representations assessed with the Adult Attachment Interview (M. Main & R. Goldwyn, 1994). In Study 2, the interactions were independently scored with the Rapid Marital Interaction Coding System (RMICS; R. E. Heyman & D. Vivian, 1993), a communication-based system. The SBSS predicted relationship variables beyond the RMICS, especially for women. Results indicate that the secure base phenomenon provides a cogent perspective on adult attachment behavior.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
