Coppery titi monkeys (Plecturocebus cupreus) are socially monogamous South American monkeys that display strong social bonds. Infants form selective bonds with their fathers, making them ideal for studying father-daughter bonds. We established a method for quantifying variability in expression of bond-related behaviors in females (n = 12), and the present study is the second to use this method for explaining titi monkey responses to behavioral tests. We also investigated how manipulations of oxytocin (OT) and vasopressin (AVP) influenced juvenile behavior and physiology. Subjects received acute intranasal treatments of saline, low/medium/high OT, low/high AVP, or OT receptor antagonPsychoneuroendocrinologyTiti monkey father-daughter bond-related behaviors explain stress response variability.PMC11759130R01 HD092055P51 OD011107Freeman SMBaxter AWitczak LRArias-Del Razo RLau ARSavidge LEGoetze LRDufek MKaraskiewicz CRothwell ESFerrer ESamra JBales KLfalseTiti monkey father-daughter bond-related behaviors explain stress response variability.Social interactions regulate our behavior and physiology, and strong social bonds can buffer us from stress.
