The current study analyzed the interactions of one family, in a laboratory context, by means of interviews with the parents and of family members participation in tasks similar to those in everyday life - Lunch, Poster, Play and Organization of the Room. An ABACA design was employed. Condition A was baseline. The independent variable was a written text describing behaviors of a traditional family (Condition B) and of a contemporary family (Condition C). Based on the categorization of all participants interactions and the partial interval recording, it was observed that family interactions differed more among the tasks, independent of the condition, than between the baseline and experimental conditions. The results indicated that the behavior of the participants were similar to those observed in the natural environment.
