This work studies verbal conflict between parents and preadolescents through analysis of family dinnertime conversations. We move from the assumption that verbal conflict is an educational instrument of interaction and a tool of socialization. The aim of the research is to analyze the participants' strategies in situations of conflict and to highlight the relations between parents and preadolescents in these specific situations. The data collection methodology is mainly ethnographical: videotape recordings of Italian middle class family dinners (the families were selected as being dual career ones with two children) were fully transcribed and codified following the approach of Conversation Analysis. The results of the quantitative (by the use of the log-linear models) and qualitative analyses confirm the importance of verbal conflict in family context as a particular cultural strategy of relationships between parents and preadolescents. The analytical data underline the relations between different aspects of conflict and the pragmatic implications for all family members at dinnertime conversations. (Contains 2 figures, 4 tables, 4 excerpts and 11 notes.)
