A abordagem contrastiva na terapia fonológica em diferentes gravidades do desvio fonológico

Abstract

This study aimed at comparing three models of contrastive approach in the treatment of different severities of phonological disorder and analyzes the structural generalization obtained. The sample was composed by nine subjects with phonological disorders, being them with the age 4:2 and 6:6 years old. All subjects were evaluated, before and after phonological therapy. Three groups were established for the treatment, having them three subjects each. Every group had one representative with severe, moderate-severe and mild-moderate disorder and each one was treated by one different model Minimal Opposition, Maximal Opposition/Empty Set and Multiple Oppositions. The initial and final phonological assessments were compared taking into consideration the number of phonemes in the phonological systems, the number of sounds in the phonetic inventory, the distinctive features changed, the Percentage of Consonants Correct (PCC) and the generalizations (to non used items during treatment, for other positions in the word, inside a sound class and for other sound class). After, it was carried out the statistical analysis using the Friedman Test, considering p<0, 05 and it was done the descriptive analysis among the models. There was no statistical difference among the models considering the severity of phonological disorder. The Minimal and Maximal Opposition/Empty Set approaches favored a greater number of acquisitions of sounds in the phonetic inventory in subjects with severe and moderate-severe degrees while the Multiple Oppositions approach favored a better performance in the acquisition of sounds in the phonological system and a decrease in the impaired distinctive features in severe and moderate-severe disorder. It was verified an increase of PCC and the occurrence of different types of generalization in all groups however there was no statistical difference among them. The models of therapy were effective in the treatment of different severities of phonological disorders and favored the occurrence of structural generalization observing the best performance in children with severe and moderate-severe disorder.
