Responsiveness to babies: Life-situation specific sex differences in adulthood

Responsivity to babies was observed in 96 mature adults representative of three junctures of parenthood: parents of infants, parents of 8-to-9-year-olds, and parents of adolescents. Among the measures used were reactions to an unfamiliar infant in a waiting room, interest in pictures of babies versus other objects, and sex-role concept and attitudinal questionnaires. Stage of family life cycle affected women's responsivity, but not men's. New mothers displayed a heightened generalized interest in babies which is optimally timed and functional in terms of sex-differentiated role requirements. A possible confounding between cohort effects and stage in the family life cycle was examined and rejected. Traditionally sex-typed behaviors were reinterpreted as life-situation specific rather than general traits.This study was supported by grants from NIMH (1 R03 MH28264-01) and from Boys Town Center for the Study of Youth Development, Stanford University.
