Oxytocin and social preference data on young adult relationships to romantic partners, parents, friends, and strangers.

Forty Four young adults (91% female) in ongoing romantic relationships (M duration=21 months) completed a screening survey and two lab visits separated by 4-weeks. Results indicated that oxytocin administration decreased attachment to mothers, decreased attachment to subsidiary figures, and decreased attraction to strangers, but showed no effect on closeness to romantic partners or to the primary attachment relationship.
