The case of a 4 year old congenitally blind child, with developmental alterations, was analyzed, according to assumptions of constitutive language (Franchi, 1977) and semiotic mediation (Rodríguez & Moro, 1999). Seven sessions of intervention were transcribed and analyzed, comprising a period of two years. The adaptation of the methodology of Rodríguez & Moro allowed the observation of the following aspects: the acquisition of use of objects (from less conventional uses to more conventional uses), the participation in play activities (eg: nursery rhymes) and the appearance of different modes of communication. Different aspects of the adult-child interaction were given significance, expanding the scope of the original proposition in relation to the role of semiotic mediation. The implications of the study to the area of Special Education were discussed.
