in the present commentary we expand on two concepts relevant to understanding affliliative bonding. differences and similarities between the functions and actions of oxytocin and vasopressin are difficult to study but may be critical to an understanding of mechanisms for social bonding. what is termed here a “trait of affiliation” may reflect in part the capacity of these same peptides to program the developing nervous system.
