Abstract
Squirrel monkeys classified into 10 categories regarding sex, age and reproductive status were assessed for their responsiveness to young infants. Adult males made significantly fewer contacts with the infant than females, although immature males did not differ from females on this measure. None of the males showed complete retrieval of the infant. Amongst the females, immatures and females close to term in pregnancy were most responsive in terms of contact and retrievals. Neither wild nor laboratory rearing, nor early pregnancy influenced response patterns in females. Different response rates in matures and immatures of each sex and the basic differences between the sexes are considered in terms of possible hormonal determinants.
