“…The high performance in the directed attention stages in the dichotic listening tests, when compared with the binaural integration stage, has been reported previously (19) . The studies have shown that the difficulties observed in the stages of binaural integration, in dichotic listening tests, may occur because of the alterations in the skills of attention and/or working memory (20) .…”

RESUMO Objetivo: Comparar o desempenho, na versão em português brasileiro, do teste de identificação de sentenças dicóticas (DSI) entre: as orelhas direita e esquerda e escolaridade em indivíduos audiologicamente normais. Métodos: Foram avaliados 200 indivíduos normouvintes, destros, separados em sete grupos de acordo com os anos de escolaridade.Todos os sujeitos foram submetidos à audiológica básica e comportamental do processamento auditivo (teste de localização sonora, teste de memória para sons verbais e não verbais em sequência, testedicótico de dígitos e DSI). Resultados: Os sujeitos avaliados apresentaram média de escolaridade de 13,1 anos e resultados adequados nos testes selecionados para a avaliação audiológica e do processamento auditivo. Em relação ao teste DSI, a escolaridade teve relação de dependência com as porcentagens de acertos em cada etapa do teste e com a orelha avaliada. Houve correlação positiva estatisticamente significante entre a escolaridade e a porcentagem de acertos para todas as etapas do teste DSI em ambas as orelhas. Também houve efeito do grau de escolaridade nos resultados obtidos em cada etapa do teste DSI, com exceção da etapa de escuta direcionada à direita. Conclusões: Na comparação do desempenho considerando as variáveis estudadas no teste DSI, concluiu-se que: há vantagem da orelha direita e quanto maior o nível educacional, melhor o desempenho dos indivíduos.

“…To participate in the study, the subjects should meet the following eligibility criteria: age between 18 and 40 years; hearing thresholds within the normal range, i.e. a maximum of 25 dB at frequencies between 250 Hz and 8000 Hz, and at least complete secondary education, in order to avoid the variable "schooling" from interfering with the responses (13) . Individuals who did not accept to participate, did not meet the selection criteria or presented any factor that could interfere with the test, such as neurological changes and/or verbal fluency disorders, were excluded from the sample.…”

Purpose: To develop Brazilian Portuguese Dichotic Sentence List Test, check its applicability and propose an application protocol for auditory processing assessment. Methods: The lists of sentences were taken from the original material, analyzed in detailed and adapted to form the new test. To compose pairs of sentences with as much of the same duration as possible, the duration of each sentence was statistically analyzed within the same list and among lists. The lists were combined in increasing order of length, within each list; and combinations of the lists were formed according to the length of sentences, resulting in 42 different sets of lists. Then, the test was performed with 42 normal hearing individuals. Individuals were instructed on how to answer: initially, they should repeat the sentences presented to both ears (attention divided between the right and the left ears). Then, the steps for the right ear phrases (attention directed to the right ear), and finally for the left ear (attention directed to the left ear) were performed. Results: The new material was composed as follows: track 1, pure tone calibration; track 2, modified 1A list; and tracks 3 to 44, the 42 possible combinations among the lists. After the test was applied, an application protocol was suggested. Conclusion: The Brazilian Portuguese Dichotic Sentence List Test was developed and proved to be an instrument that can be used in adults. Therefore, a protocol was proposed with two different combinations of lists and presentation sequence for auditory processing assessment.Keywords: Hearing; Speech discrimination tests; Auditory perception; Audiology; Hearing Tests RESUMO Objetivo: Desenvolver o teste Listas de Sentenças Dicóticas em Português Brasileiro, verificar sua aplicabilidade e propor um protocolo de aplicação para avaliação do processamento auditivo. Métodos: As listas de frases foram extraídas do material original, submetidas a uma análise criteriosa e ao processo de adaptação, para compor o novo teste. Para formar pares de frases com duração mais aproximada possível, foi analisado estatisticamente o tempo de duração de cada sentença, dentro de uma mesma lista e entre listas. Estas foram combinadas em ordem crescente de duração, dentro de cada lista, e realizadas as combinações das listas entre si, de acordo com a duração das sentenças, gerando 42 conjuntos distintos de listas. Em seguida, o teste foi aplicado em 42 indivíduos normo-ouvintes. Os indivíduos foram instruídos sobre a forma de resposta, devendo repetir, inicialmente, as sentenças de ambas as orelhas (atenção dividida entre orelha direita e esquerda), em seguida, as frases da orelha direita (atenção direcionada para a orelha direita) e, finalmente, as da orelha esquerda (atenção direcionada para a orelha esquerda). Resultados: O novo material ficou composto da seguinte forma: faixa 1, tom puro de calibração; faixa 2, lista 1A modificada e faixas 3 a 44, as 42 possibilidades de combinação entre as listas. Após a realização do teste, foi sugerido um protocolo ...

“…Brain imaging studies (Abe et al, 2002;Janowsky, Kaye & Carper, 1996;Johnson, Farnworth, Pinkston, Bigler & Blatter, 1994;Nusbaum, Tang, Buchsbaum, Wei & Atlas, 2001;Salat et al, 2005) suggest that age-related changes to the microstructure of the corpus callosum may occur, which may lead to a deficit in the interhemispheric transfer process. This degenerative change has the potential to alter the normal processing of auditory stimuli that are presented binaurally, and may help to explain left ear performance deficits observed in behavioural tests using dichotic measures, particularly for males (Gootjes, Van Strien & Bouma, 2004;Roup, Wiley & Wilson, 2006).…”

Older adults, with and without measured hearing loss, often report difficulties in following rapid speech and difficulties in understanding speech in noisy environments. It is likely that these difficulties arise from: (a) deteriorating peripheral hearing and/or (b) structural changes to the central auditory system (CAS) and/or (c) changes to normal cognitive function. This review will focus on the structural changes to the CAS and the likely central auditory processing (CAP) abnormality arising from these changes. Older, compared with young normal hearing adults, show neurophysiological and behavioural differences on measures of sound localisation, and in the detection of small and/or rapid changes to the temporal properties of various auditory stimuli. This article will review these differences together with prevalence and risk factors for CAP abnormality in older adults. The impact of this condition on the older adult as well as potential approaches to rehabilitation and (re)training will also be reviewed.Hearing is estimated to deteriorate at around 9 dB per decade over the age of 55 years (Davis, Ostri & Parving, 1991) and the likelihood for measured hearing loss increases by around 14% for each year of age over 50 years (Mitchell, 2002). Loss of this sensory input can be debilitating, with a recent publication by the Australian Institute of Health and Welfare identifying hearing loss and agerelated vision disorders among the top 12 causes of years of life lost due to disability in Australia (Mitchell, 2002). The existence of measured hearing loss alone however, does not fully account for the increased difficulties in understanding speech that are so often reported by older adults.In 1988, the working group on speech understanding and aging (Working Group on Speech Understanding and Aging, 1988) proposed the existence of three models that attempt to explain age-related decline in the ability to understand speech. These models were: (a) deterioration in peripheral hearing; (b) structural changes to the central auditory system (CAS), which consists of the brainstem and forebrain (Humes, Christopherson & Cokely, 1992;Webster, 1999); and (c) changes to normal cognitive processes.While it is quite possible that all three models are equally important in understanding age-related changes to understanding speech, the purpose of this review article will be to focus on the second model, that is, the structural changes to the central auditory system, and the likely central auditory processing (CAP) abnormality arising from this. This review article will examine: (a) the anatomical, behavioural and electrophysiological evidence for CAP abnormality, (b) prevalence and risk factors for the condition and (c) the possibility of remediation for this condition. It should be noted that when statistical significance is reported, a p value < .05 is implied unless otherwise specified.
