This paper reviews the literature concerning differences in the linguistic style of girls/boys in everyday interactions, and presents empirical data from a study with Greek school children. Two age groups were studied, 6.5 years (N=100) and 9.5 years (N=100), respectively. Everyday life situations were presented, asking children to express what they would do if a certain situation occurred. Our main hypothesis predicted that girls would adopt a more passive and submissive conversational style whereas boys would express themselves using more dominant and more aggressive communication styles. The results confirmed the above prediction: gender differences were observed when children responded to hypothetical everyday life situations. However, at 9.5 years, differences in dominant/submissive style and also in talkativeness became much milder. Results are interpreted in the frame of a combined socio-cultural and social-developmental account. The differences observed appear to be related to specific "masculine" and "feminine" roles, attributed to the two sexes by societal norms. (Contains 4 tables.)
