Toward a neuroscience of parenting : adult attachment and oxytocin affect neural and behavioral responses to infant attachment signals

Abstract

As infants are fully dependent on their parents, correct perception and interpretation of infant signals is crucial for infant survival. It is therefore not surprising that specific brain circuits and neuroendocrine processes have evolved to perceive infant signals correctly and to respond adequately. However, parents vary in their ability to respond to their infants in a sensitive way and several factors may be involved in parental sensitive responsiveness. One important factor influencing parenting behavior is the neuropeptide oxytocin. Of all the hormones involved in parenting and other social behaviors, oxytocin has received the most interest, as evidenced by the high number of scientific studies over the past decade (Bos, Panksepp, Bluthé, & Honk, 2012; Van IJzendoorn & Bakermans-Kranenburg, 2012). Many studies suggest that oxytocin is related to sensitive parenting (Bakermans-Kranenburg & Van IJzendoorn, 2008; Feldman, Weller, Zagoory-Sharon, & Levine, 2007), although the exact mechanism underlying this positive association is not entirely clear yet. Another factor that influences parenting behavior is adult state of mind with respect to attachment (Van IJzendoorn, 1995). In the current dissertation, the role of oxytocin and adult attachment in parenting is examined with a series of functional magnetic resonance imaging experiments.LEI Universiteit LeidenDevelopment Psychopathology in context: famil
