Attachment research has predominantly focused on two hormones: oxytocin and cortisol. Oxytocin is a critical hormone in lactation, nurturance, and trust. Higher oxytocin levels are associated with maternal sensitivity to infants (Feldman, Weller, Zagoory‐Sharon, & Levine, 2007), quality of play and contact with infants (Feldman, Gordon, Schneiderman, Weisman, & Zagoory‐Sharon, 2010), and maternal trust in adolescents (Venta et al., 2017). Further, cortisol, a hormone released by the HPA axis in response to stress, has been found to differ between secure, disorganized, and insecure children (Spangler & Grossman, 1993). Similarly, Schieche and Spangler (2005) found that securely attached and behaviorally inhibited infants experienced declines in cortisol after a challenging task, whereas avoidant infants experienced a decrease in cortisol early on, followed by an increase in cortisol after the task. While the design and findings of these studies are complex, they lend some support for a cortisol‐coping hypothesis (Spangler & Grossman, 1993).
