BAGETTI, Tatiana; CERON, Marizete Ilha; MOTA, Helena Bolli and KESKE-SOARES, Márcia. Phonological changes after the application of therapy approach based on distinctive features in the treatment of phonological disorder. J. Soc. Bras. Fonoaudiol. [online]. 2012, vol.24, n.3, pp. 282-287. ISSN 2179-6491. http://dx.doi.org/10.1590/S2179-64912012000300015.
This study aimed to compare the phonological changes due to the application of a speech therapy approach based on distinctive features, using two types of target sounds (the ones which emphasize the contrast, and others which reinforce the distinctive features) in the treatment of phonological disorder. The sample was constituted by seven children with phonological disorder (four boys and three girls), with ages between 3 years and 10 months and 6 years and 9 months. The children were classified according to the severity of the phonological disorder and then underwent treatment based on the Modified Maximal Oppositions Model. Two subjects were grouped for each degree; one subject was treated by "contrast" and the other one by "reinforcement" of the distinctive features in which they showed difficulties. The moderate-severe degree was the only one to include only one subject. After 20 therapy sessions, the phonological changes before and after the treatment were analyzed, considering the type of stimulus presented ("contrast" or "reinforcement"). All subjects, either treated by "contrast" or "reinforcement", showed an increase in their Percentage of Consonants Correct (PCC), in the number of acquired sounds and of generalizations in their phonological inventories. It was verified that both groups presented changes in their phonological inventories. On the comparative analysis between the groups, it was observed that both groups, treated by "contrast" and by "reinforcement", demonstrated differences regarding the types of generalizations studied.
