The treatment with rothics and generalization obtained in two models of phonological therapy.

This study had the aim to analyze both the phonological changes and the generalization obtained in the treatment with rothics in two models of phonological treatment. The sample consisted of four subjects diagnosed with phonological disorder, with ages between four and six years. All of them were assessed before and after the phonological therapy. Two groups were established for the treatment with rothics. One group was treated with ABAB - Withdrawal and Multiple Probes Model, and the other group with the Maximal Opposition Model. The phonological system and the occurrence of generalizations before and after the treatment were analyzed. It was found that none of the subjects acquired the rothics that were practiced in the treatment, however, the occurrence of generalization to untreated items was observed only in the subjects treated by the ABAB - Withdrawal and Multiple Probes model. The other types of generalization occurred in both models. The Maximal Opposition Model provided greatest changes in the phonological system of the subjects, which can have been favored by the other target-sound of the pair.
