Forty-three low-income Brazilian families (mother, father, and child) were observed in free play interaction. Multidimension assessments of the degree of dyadic and triadic interactional synchronies were made (interpersonal distance, visual and body orientation, play involvement, and shared affect). Results indicated that father每child dyadic interaction was more strongly associated with triadic family interaction than mother每child interaction. Furthermore, father每daughter dyads and triads with girls were more attuned than all other family compositions. Taken together, these results expand research in the field and suggest that fathers may have a greater impact on child gender development than previously thought. Our findings also add empirical evidence to the unique contribution of the triadic family context for understanding of parental roles and family dynamics %K mother每child interaction %K father每child interaction %K triadic interaction %K family processes %K gender socialization %U https://journals.sagepub.com/doi/full/10.1177/0192513X19832938
