PURPOSE: To analyze the generalization based on the implicational relationships obtained by the "ABAB Withdrawal and Multiple Probes Model" in children with different severity degrees of phonological deviation. METHODS: Speech data analysis of eight subjects with phonological deviations. Evaluations of receptive and expressive language, oral sensory-motor oral system, psychomotricity, hea-ring discrimination and phonology were carried out, in addition to audiological, otorhinolaryngological and neurological evaluations. Next, the severity degree of the phonological deviation was determined, and the treatment was initiated, using the "ABAB Withdrawal and Multiple Probes Model". RESULTS: Generalizations based on implicational relationships were observed. CONCLUSIONS: The "ABAB Withdrawal and Multiple Probes Model" was effective in the treatment of subjects with phonological deviation. The generalization based on implicational relationships coincided, partly, with the Implicational Model of Features Complexity.
