Developing referential communication skills: The interaction of role-switching and difference rule training

Although both substantive knowledge and enabling skills are important to the development of referential communication, deficits in procedural knowledge may account for a significant portion of preschoolers' communicative failures. The results of this training study with 5-year-olds revealed that they lack two major procedural skills. They do not know the importance of differentiating referents from nonreferents. They also are unaware that the speaking and listening roles are, at least in part, complementary; that is, certain rules are applicable to both. After training which provided specific instruction on the nature of informative messages (in either the speaking or listening mode, but not both) and role-switching experience, performance improved both on tasks in the trained and in the nontrained modalities. Discussion focuses on both the practical implications and the theoretical significance of these results.
