Our research explores the biological correlates and consequences of individual differences in adult attachment. We are particularly interested in hormones linked with nurturance (e.g., estradiol, testosterone) and stress (e.g., cortisol). Estradiol, for instance, has been associated with bonding and caregiving in humans and other mammals, suggesting that it may be quite relevant to close relationships. Our work provides novel evidence that avoidant individuals have lower baseline estradiol levels (Edelstein, Stanton, Henderson, & Sanders, 2010), which may at least partially explain their difficulties with intimacy. In an experimental test of this idea, we found that emotionally intimate stimuli (but not other positive stimuli) elicited increases in estradiol; however, highly avoidant women did not show these effects (Edelstein, Kean, & Chopik, 2012). Our other ongoing projects explore the role of attachment in physiological and psychological responses to intimate relationship experiences, such as cuddling (van Anders, Edelstein, Wade, & Samples-Steele, 2013).
