This article argues that individuals paradigms have predominated social scientific explanations for gendered behavior in intimate relationships but that a microstructural paradigm adds necessary additional information. The results of a study designed to test the relative strengths of individualist and microstructural explanations for “mothering behavior” are presented. The microstructural hypothesis is that single fathers will adopt parental behavior that more closely resembles that of women who mother than that of married fathers. Parenting behaviors of single fathers, single mothers, married parents (...) with mothers at home, and married two-paycheck couples are compared. Overall, the hypothesis is supported. The article ends with a discussion of the implications of the microstructural perspective for social change in a feminist direction. (shrink)
