Background: A review of literature shows that cochlear implant (CI) users face difficulties in terms of music interpretation when compared to regular hearing (RH) counterparts. The electrically pulsing nature of the CI acts differently than sound waves in a normally functioning ear, leading to different interpretations of musical concepts such as pitch or timbre. An exceptional case however has been observed in a university-level violinist with bimodal hearing (congenitally deaf in the right ear, and with very minimal residual hearing in the left; they use one CI and one hearing aid) at the University of Ottawa. Objective: This study will compare the pitch recognition, timbre preference and audiation (linked to pitch and rhythmic perception) abilities between an exceptional CI user and case-control RH violinists. Data has previously been collected on CI users not playing the violin due to CI technology's limitations in pitch processing. Since the violin is considered a pitch-heavy instrument to play, it is expected that the study participant has exceptional pitch recognition skills when compared to other CI users (and perhaps RH peers), while still demonstrating comparable timbre preference and rhythmic audiation abilities to an RH comparison group. Method: Three tests were administered relating to pitch recognition on a violin-like interface, timbre preference between two heard tones, and an Advanced Measures of Music Audiation (AMMA) test for general musical knowledge in pitch and rhythm-based melodic discrimination. Results were compared between the critical case-study with CIs and RH control participants to quantify a basis in pitch perception, timbre preference and melodic audiation (applied to pitch and rhythm) skills. Implications: The study participant demonstrated comparable timbre preference and rhythmic discrimination skills to an RH comparison group. The study participant demonstrated pitch perception skills higher than previously tested CI users, despite being lower than the RH comparison group. The CI-using study participant would have developed these higher-than- average pitch perception skills through rigorous early-age training, and passion and persistence of music training on a pitch-heavy instrument despite known recommendations. This sheds light on the CI's technology not necessarily limiting users' choice of instrument due to its pitch processing, despite previous recommendations.

Uma questão de pesquisa e intervenção diz respeito às condições sob as quais estes repertórios se estabelecem e se expandem a partir do uso do IC. Este estudo teve como objetivo verificar se implantados cocleares pré-linguais aprenderiam relações condicionais entre palavra ditada e figura (AB) e entre figura e palavra impressa (BC) via exclusão; e se a aprendizagem destas relações seria condição para a emergência de relações transitivas (AC) e simétricas (CB), para a nomeação de figuras (BD) e de palavras impressas (CD) e para o responder generalizado diante das mesmas palavras ditadas no ensino (voz feminina de adulto), mas com outra intensidade e freqüência de voz (voz masculina de adulto e de criança). Foram realizados dois estudos com objetivos semelhantes, porém, com uma diferença procedimental. No Estudo 1, três crianças entre seis e sete anos de idade, com surdez pré-lingual e usuárias de IC modelo Nucleus 24k foram expostas a tarefas de emparelhamento de acordo com o modelo, pelo software MTS®. As sessões foram realizadas individualmente e gravadas em fitas VHS para registro e análise das vocalizações. O procedimento iniciava com o Pré-treino e, posteriormente, o repertório inicial era avaliado no Pré-teste, a partir do qual eram escolhidos os estímulos que participariam do ensino e testes subseqüentes. O procedimento de ensino da linha de base (AB e BC) foi o ensino por exclusão. Após a aquisição da linha de base, eram conduzidos testes de formação de classes (AC e CB), seguidos pelos testes de generalização, de nomeação de figuras (BD) e de palavras...

A case of research and intervention describes the conditions in which these repertories are established and expand from the use of CI. The present study aimed to verify if prelingual cochlear implanted subjects, would learn conditional discriminations between the dictated word and the picture (AB) and between the picture and the printed word (BC) by exclusion; and if learning these discriminations would be a condition for the emergence of transitive relations (AC) and symmetric (CB), for the nomination of pictures (BD) and printed words (CD) and for answering in a general way, facing the same words dictated when teaching (adult female voice), with different intensity and voice frequency (male voice of adult and child). Two studies, with similar objectives were realized, employing a different procedure. In study n° 1, three children whose ages ranged from six to seven years of age, with prelingual deafness and users of CI, model Nucleus 24k were exposed to matching-to-sample, according to the model, using software MTS®. The sessions were realized individually and recorded in VHS for registering and analysis of the vocalizations. The procedure started with the Pre-training and afterwards, the initial repertory was evaluated on the Pre-test and then the stimuli were selected in order to take part of the teaching and subsequent tests. The baseline teaching procedure (AB and BC) was by exclusion. After the acquisition of the baseline, classes of equivalent stimuli tests were conducted (AC and CB), followed by the generalization tests, nomination of pictures (BD) and words (CD).

The purpose of this investigation was to determine the prevalence of specific learning disabilities in school-aged hearing impaired children based on the proposed theoretical definition of the National Joint Committee for Learning Disabilities (1981) and the theoretical definition constructed by the Canadian Association for Children and Adults with Learning Disabilities (1981). The operationalization of these theoretical definitions, coupled with the current operational definition issued by the Texas Education Agency (1983), formulated the investigative framework.
