The purpose of this study was to detect the differential communicative abilities that distinguishes the communicative exchange between blind and sighted couples, from a referential ecological framework. The sample was composed of 18 children (9 sighted and 9 blind) between 8 and 12 years old. Children were grouped by three conditions according to the vision level of couples (blind-blind; blind-sighted and sighted-sighted). The experimetal task used was the 'organization of a room' designed by Boada and Forns (in this monograph). The task was adapted to tridimensionality, and coded following their autors' instructions. Results suggest that blind children couples need to use more communicative skills to avoid communicative faillur and that they are less specific in he differentiation of emisor-receptor roles.
