While not itself a cross-cultural study, the present work makes a significant contribution to cross-cultural research by providing an updated coding system and scores on parental nurturance (based on the past 25 years of attachment theory) for all societies of the Standard Cross-Cultural Sample (SCCS) . Aronoff describes the existing literature and coding systems as they inform and relate to the development of his own coding scheme. Subsequently, Aronoff presents the multi-leveled coding system that integrates several conceptions of parental nurturance, as well as codes for the SCCS societies.

This study tests the claim that male and female investment in the socioemotional and economic aspects of family life are inversely related. Results suggest that this hypothesis is not supported, although a significant inverse relationship between male and female infant care does exist.
