Orientador: Ana Cláudia Moreira Almeida-Verdu / Banca: Adriane Lima Mortari Moret / Banca: Alessandra Turini Bolsoni Silva / Resumo: Estudos da parceria entre a Fonoaudiologia e Análise do Comportamento têm investigado sob quais condições de ensino implantados cocleares pré-linguais aprendem habilidades auditivas e as relações que estabelecem com a produção oral. Uma rota que permite a extensão do controle entre repertórios verbais é o Ensino por Múltiplos Exemplares (do inglês Multiple Exemplar Instruction, MEI), que tem sido pouco explorada em estudos com usuários de implante coclear. Este estudo objetivou investigar o efeito do ensino por MEI sobre a integração entre repertórios de ouvinte e falante em crianças com Desordem do Espectro da Neuropatia Auditiva (DENA) e usuárias de implante coclear (IC). Participaram três crianças com 6 anos de idade, uma do sexo feminino e duas do sexo masculino, com o diagnóstico de DENA e um quadro de perda auditiva severa-profunda, bilateral e pré-lingual. Todos os participantes usavam implante coclear uni ou bilateral, frequentavam o ensino regular e recebiam atendimento multidisciplinar no follow-up do serviço de implante coclear. Os participantes apresentavam maturidade intelectual típica e reconhecimento auditivo inferior à idade cronológica, aferidos pela Escala Colúmbia de Maturidade Intelectual e o Peabody Picture Vocabulary Test (PPVT-4R). Foram adotados estímulos auditivos e figuras que corresponderam às palavras (substantivos) e sentenças de dois termos (substantivos+adjetivos), que foram convencionais (para GABI e SOZA) e não convencionais (para DOZA).

A route that can be to promote the extension of control between verbal repertoires is designated Multiple Exemplary Instruction (MEI), which has been little explored in studies with cochlear implants users. This study aimed to investigate the effect of MEI' teaching on the integration between listening and speaking repertoires in children with Auditory Neuropathy Spectrum Disorder (DENA) and cochlear implants users (CI). Participants were three 6-year-old children, one female and two males, with the diagnosis of DENA and a severe-profund, bilateral and pre-lingual hearing loss. All participants used a uni or bilateral cochlear implant, attended regular education and received multidisciplinary care in the follow-up of the cochlear implant service. Participants had typical intellectual maturity and auditory recognition lower the chronological age, measured by Columbia and PPVT-4R tests. Auditory stimuli and figures that corresponded to words (nouns) and sentences of two terms (nouns + adjectives) were used, which were conventional (GABI and SOZA) and nonconventional (DOZA). The study employed a multiple probe design and was composed of probes and teaching. The probes were intercalated with the teaching and evaluated the conditional a...

The cochlear implant represents a radical intervention in the hearing-impaired child's life, which has a profound influence on the feelings and emotions of the child's family. In this study it is endeavoured to identify and to describe this influence. A literature study was done. Families of implanted children in Scotland and in South Africa filled in questionnaires and interviews were held. This study illuminates the fact that parents suffer stress and have various concerns before as well as after the implant. Different reasons why parents decide to give their child a cochlear implant are described. The researcher came to the conclusion that the implanted child functions in a more balanced way and that parents are very satisfied after the implantation. The effect of the implant is described under the following categories: communication, feelings of parents, effect on the deaf child, normality, effect on parents, effect on siblings. / Education / M.Ed.(Guidance and Counselling)

A avaliação eletrofisiológica tem sido recomendada para complementar a avaliação comportamental do processamento auditivo. Objetivo: Verificar e comparar as respostas auditivas comportamentais de processamento temporal e resposta de média latência com o processamento cognitivo em idosos, candidatos e novos usuários de próteses auditivas. Métodos: Participaram do estudo 60 idosos, sendo 20 sexo masculino e 40 sexo feminino, cuja faixa etária era 61 a 85 anos (média 71,7 anos), atendidos no Núcleo Integrado de Assistência, Pesquisa e Ensino da Audição (NIAPEA) da Escola Paulista de Medicina da Universidade Federal de São Paulo, todos novos usuários de prótese auditiva. Os indivíduos foram reunidos em dois grupos segundo o grau da perda auditiva, ao considerar as frequências de 500 a 4000 Hz do audiograma, denominados de Grupo I (GI) e Grupo II (GII). No GI os indivíduos apresentavam grau de perda auditiva inferior ou igual a 50 dB, e no GII, superior ou igual a 51 dB. Os aspectos cognitivos foram avaliados por meio do Potencial Evocado Auditivo de Longa Latência – P300, Mini-Exame do Estado Mental (MEEM) e Escala de Avaliação da Doença de Alzheimer (ADAS-COG). Os procedimentos selecionados para contemplar os objetivos foram o Potencial Evocado Auditivo de Média Latência (PEAML), no qual foi estudada a latência das ondas Na e Pa (milissegundos), amplitude do complexo Na-Pa (microvolts) e quando ocorreu a presença de efeito auditivo e/ou eletrodo o exame foi considerado alterado. Ainda, foram aplicados o Teste Padrão de Duração (TPD) e Teste de Detecção de Gap no Ruído (GIN) no qual foram analisadas as respostas de identificação correta, e o limar de acuidade temporal. Resultados: Os idosos usuários de prótese auditiva apresentaram menor limiar de acuidade temporal, maior reconhecimento de gaps e de discriminação do padrão de duração, menor latência e diminuição das alterações do PEAML em relação ao momento em que eram candidatos. Quando mostravam déficits no processamento da informação em área auditiva primária, apresentaram prejuízo na habilidade auditiva de resolução temporal, que piorava na presença de alteração cognitiva. Conclusão: Houve deterioração das habilidades de resolução e ordenação temporal, independente do grau da perda auditiva, mostrando o efeito- idade originado pelo envelhecimento. As respostas do Potencial Evocado de Média Latência também não foram influenciadas pelo grau da perda auditiva e ocorreu mudança significativa na reavaliação após a aclimatização. Assim, o efeito de estimulação acústica pelo uso de prótese auditiva melhorou a habilidade auditiva de ordenação temporal, resolução temporal e o processamento das informações do Sistema Nervoso Auditivo Central até o córtex temporal primário. O comportamento de ordenação temporal não se modificou nos idosos com alterações cognitivas, no entanto indivíduos sem alteração cognitiva têm menor déficit na integridade funcional das áreas auditivas primárias e melhora no comportamento de resolução temporal. / Introduction: Aging can cause alterations in temporal processing and cognitive functions. Electrophysiological evaluation has been widely recommended to complement the behavioral evaluation of auditory processing. Objective: Verify and compare the behavioral auditory responses of temporal processing and the auditory middle latency response with cognitive processing in elderly candidates for and users of hearing aids. Methods: Sixty elderly people participated in the study, 20 males and 40 females, ranging in age from 61 to 85 (avg. 71.7) who are attended at the Integrated Hearing Assistance, Research and Education Center (NIAPEA) of the Federal University at São Paulo, and who are all new users of hearing aids. The individuals were organized in two groups according to their degree of hearing loss, considering frequencies of 500- 4000 Hz on the audiogram, denominated Group I (GI) and Group II (GII). In GI, the individuals had a degree of hearing loss lower than 50 dB and in GII above 50 dB. The cognitive factors were evaluated by means of long-latency auditory evoked potential tests– P300, Mini mental state examination (MMSE) and the Alzheimer Disease Assessment Scale (ADAS-COG). The procedures selected to achieve the objectives were the Middle Latency Auditory Evoked Potentials (MLAEP) tests, which studied the latency of the Na and Pa waves in milliseconds, and the amplitude of Na-Pa (μv). When an auditory and or electrode effect was present, the exam was considered altered. The Duration Pattern Tests (TPD) and Gap in Noise (GIN) test were used to analyze the responses of correct identification, and the gap detection threshold. Results: Elderly people who use hearing aids display a lower gap detection threshold, greater recognition of gaps and of discrimination of the duration pattern, lower latency and decrease in MLAEP in relation to the time when they were candidates. When they displayed deficits in information processing in auditory cortex, they displayed losses in the temporal resolution ability, which became worse in the presence of cognitive alteration. Conclusion: The temporal ordering and temporal resolution abilities deteriorated independent of the degree of hearing loss, revealing the age effect. The responses to Middle Latency Auditory Evoked Potentials tests were not influenced by the degree of hearing loss and significant changes in reassessment occurred after acclimatization. Thus, the effect of acoustic stimulation by the use of a hearing aid improved the hearing ability of temporal ordering, temporal resolution and the processing of information from the Central Auditory Nervous System to the primary auditory cortex. The behavior of temporal ordering did not change in the elderly with cognitive alterations; however, individuals without cognitive alterations had lower deficits in the functional integrity of the primary hearing areas and improvement in the behavior of temporal resolution. / TEDE / BV UNIFESP: Teses e dissertações

abstract: The present study describes audiovisual sentence recognition in normal hearing listeners, bimodal cochlear implant (CI) listeners and bilateral CI listeners. This study explores a new set of sentences (the AzAV sentences) that were created to have equal auditory intelligibility and equal gain from visual information. The aims of Experiment I were to (i) compare the lip reading difficulty of the AzAV sentences to that of other sentence materials, (ii) compare the speech-reading ability of CI listeners to that of normal-hearing listeners and (iii) assess the gain in speech understanding when listeners have both auditory and visual information from easy-to-lip-read and difficult-to-lip read sentences. In addition, the sentence lists were subjected to a multi-level text analysis to determine the factors that make sentences easy or difficult to speech read. The results of Experiment I showed that (i) the AzAV sentences were relatively difficult to lip read, (ii) that CI listeners and normal-hearing listeners did not differ in lip reading ability and (iii) that sentences with low lip-reading intelligibility (10-15 % correct) provide about a 30 percentage point improvement in speech understanding when added to the acoustic stimulus, while sentences with high lip-reading intelligibility (30-60 % correct) provide about a 50 percentage point improvement in the same comparison. The multi-level text analyses showed that the familiarity of phrases in the sentences was the primary driving factor that affects the lip reading difficulty. The aim of Experiment II was to investigate the value, when visual information is present, of bimodal hearing and bilateral cochlear implants. The results of Experiment II showed that when visual information is present, low-frequency acoustic hearing can be of value to speech understanding for patients fit with a single CI. However, when visual information was available no gain was seen from the provision of a second CI, i.e., bilateral CIs. As was the case in Experiment I, visual information provided about a 30 percentage point improvement in speech understanding. / Dissertation/Thesis / Doctoral Dissertation Speech and Hearing Science 2015
