Discriminação auditivo-visual em adultos com deficiência auditiva e implante coclear

Abstract

The expectation of the cochlear implant (CI) user is recovering auditory sensitivity and understands spoken language. Considering the auditory rehabilitation as a prerequisite for the development of language skills, the aim of this study was to investigate the effect of training on the behavior of the listener to speaker in this group, check the emergence of relationships and the generalization to indirectly taught voice different frequency. Participated of the study three adults with profound, bilateral, neurosensory hearing, loss post-lingual, CI users, with time deprivation (TD) ranging from 5 months to 23 years. Data were collected with a computer with touch screen and application programming routines for the teaching and testing. The teaching program, with seven stages, had choice according to the model. Phase 1) Pre-train for habituation, the participant with auditory-visual tasks by fading out, 2) Pre-test naming and reading, to select 8 words for training, 3) Training of relations between dictated words and figures; 4) Training of relations between dictated words and written words; 5) Testing equivalence class, which were not directly taught; 6) generalization testing, with the dictated words, with an adult male voice; 7) Post-test of picture naming and word reading. Two of the three participants learned the tasks (Phases 3 and 4), and showed equivalence class (Phase 5) e generalization (Phase 6). All of the participants improved their ability of speaking after the study (Phase 7). The performance of the participant with 23 years of TD, which presented difficulties in oral language, was low, indicating further investigation of the variables due to flaw on the training, or to the IC operation, or inappropriate use of the device, etc. More studies are required to evaluate the potential of the procedure adopted for the auditory rehabilitation of CI users.
