Validação de sinais enunciativos de aquisição da linguagem de 13 aos 24 meses

Abstract

This dissertation aimed to validate the enunciative signs of language acquisition (SEAL) for the age group of 13 to 24 months. To this end, we counted on the collaboration of judges specialized in validation of content and the longitudinal monitoring of 77 mother-infant dyads between 13 and 17 months (SEAL Phase 3) and 89 dyads between 18 and 24 months (Phase 4 ), accompanied by means of filming their playful and dialogical interaction. The filming was analyzed by two speech therapists experienced in babies' clinic and able to understand the enunciative proposal of language acquisition. For statistical analysis, the computational applications STATISTICA 9.1 and PASW 17.0 were used. As a result, the preliminary validation of two instruments, corresponding to two age groups denominated Phase 3 - 13 to 17 months composed of 7 items and Phase 4 - 18 to 24 months composed of 5 items was obtained. After factorial analysis, in Phase 3, we obtained two factors: the one factor representing the child as a subject in language, sustained in the dialogue by the adult, progressing lexically; the factor two, consisting of a single item that encompasses a set of signals indicative of typical language development. In Phase 4, all items made up a single factor, indicating that all evidence a similar direction of analysis. The results demonstrate that the signs of these two phases can differentiate groups regarding the acquisition of language, which makes them promising instruments in the process of early identification if something is not going well in the process of children's linguistic constitution.
