     All mammalian species must perform some basic types of social behavior- mothers must care for their infants, at least to the extent of lactation; and males and females must interact in order to mate. However, many mammals, and most primates, develop a much more complex array of social relationships and attachments. There appear to be many commonalities between the physiological bases of these different types of behaviors, often involving competing emotions of fear and attraction. Hormones involved in these behaviors include not only steroids such as estrogens, progestogens, and corticosteroids, but also peptides such as oxytocin and vasopressin. I will give a short history of this field of research in primates, with additional information derived from my own research, including fecal monitoring studies of wild golden lion tamarins (Leontopithecus rosalia), neurobiological studies of rhesus macaques (Macaca mulatta), and comparative data from another social mammal, the prairie vole (Microtus ochrogaster). In particular, I will concentrate on hormonal and neurobiological underpinnings of two social behaviors, parental care and pair-bonding.
