Abstract This research assessed the significance of variation in dyadic neonatal interaction for subsequent infant development in pig-tailed macaques. Adult females were selected which differed in parity and reproductive risk. The 29 dyads were housed individually to reduce external environmental influences. Large variation was observed in maternal and neonatal behavior, but it was not significantly associated with maternal or infant risk variables and could not identify six unsuccessfully reared pairs. Among the 23 successfully reared dyads, variation in nutritional and behavioral measures hypothesized to be associated with infant growth were found to be independent of neonatal weight gain. These 23 infants were separated from their mothers after 30 days and their responses at reunion were observed. Some infants clung to the mother's ventrum (attached response) while others jumped away quickly (aloof response). Prior dyadic interactions were not significantly associated with this dichotomous response, nor were maternal and most infant variables. These results suggest that dyads at risk for neonate separation when living in captive groups are not necessarily at risk in individual housing conditions. Further, pig-tailed neonates appear unaffected by variations in mother-infant interactions that do not result in separation, but neonatal characteristics may show continuity across development.
