“…Note that in the current study, participants presented with worse hearing thresholds in the LE than the RE despite showing no significant difference between ears (Table 2). Consistent with Dorman et al (1985), poorer auditory thresholds, even in the presence of normal age-appropriate hearing, is associated with older adults’ difficulties to process spectrotemporal acoustic cues to identify stop consonant syllables. In addition, CV-syllables minimize the relevance of cognitive-control processes and lexical component (i.e., internal redundancy) in DL tasks as opposed to digits and sentences which provide more lexical information (Findlen & Roup 2011).…”

Association Between the Right Ear Advantage in Dichotic Listening and Interaural Differences in Sensory Processing at Lower Levels of the Auditory System in Older Adults

Objective: Current evidence suggests that an enhanced right ear advantage (REA) in dichotic listening (DL) among older adults may originate from age-related structural changes in the corpus callosum and age-related decline in cognitive processes. Less is known about the effect of information processing at lower portions of the auditory system on DL performance. The present study investigates whether interaural differences (ID) in sensory processing at lower levels of the auditory system are associated with the magnitude of the REA in DL among older adults. Design: Sixty-eight older adults participated in the study. Participants were assessed with a DL test using nonforced (NF) and forced attention paradigms. Hearing sensitivity, transient-evoked otoacoustic emission (TEOAE), contralateral suppression of TEOAE, a proxy measure of medial olivocochlear activation, and auditory brainstem response to speech stimuli (speech-ABR) were tested in both ears separately. The ID in sensory processing at lower levels of the auditory system was derived by calculating the difference between the RE and LE for each auditory measure. Bivariate and multivariate regression models were performed. One multivariate model for each DL paradigm (NF and forced attention) was independently constructed. Measures of cognitive speed of processing and cognitive flexibility were accounted for in the regression models. Results: For both multivariate regression models, ID in pure-tone thresholds and ID in MOC suppression of TEOAE were significantly associated with the magnitude of the REA for DL among older adults. Cognitive measures of speed of processing and cognitive flexibility also contributed to the magnitude of the REA. Conclusion: These results suggest that ID in sensory processing at lower levels of the auditory system account, at least in part, for the increased magnitude of the REA in DL among older adults.

“…It has also been suggested that a greater LE deficit among older adults may be linked to age-related declines in cognitive functions (Davis et al 2015). Hällgren et al (2001) showed that working memory and speed of processing were significantly associated with DL when subjects had to selectively attend to the LE stimuli.…”

“…The effect of aging on dichotic listening tests has already been reported by several authors (3,4,20) , even when there is no great variation in an age group or when in young population, it is possible to observe differences between the performance of younger and older individuals, where young people obtained better results (3,4,20) . This fact stems from the structural and morphological changes arising from the aging process (19) and the reduction of other capacities related to superior mental functions such as memory, language, planning and sequence capacity (21,22) .…”

RESUMO Objetivo Avaliar a influência das variáveis idade, escolaridade e gênero na ocorrência de pausas após o tempo padrão no teste de identificação de sentenças dicóticas. Método A amostra foi constituída por 200 indivíduos destros distribuídos em quatro grupos segundo a faixa etária: grupo I - 13 a 19 anos de idade, grupo II - 20 a 29 anos de idade, grupo III - 30 a 39 anos de idade e o grupo IV - 40 a 49 anos de idade. Cada grupo continha 50 sujeitos (25 homens e 25 mulheres) pareados por escolaridade. Foram adotados os seguintes critérios de elegibilidade: língua materna português brasileiro, normouvinte, leitura fluente independentemente do grau de escolaridade. O teste de identificação de sentenças dicóticas foi aplicado nas etapas de integração binaural e escuta direcionada e a necessidade de pausas no teste após o tempo padrão foi anotada. Foram realizadas estatísticas descritivas e inferenciais. Resultados Para as etapas de integração binaural, houve associação positiva entre idade e ocorrência de pausas. A variável escolaridade apresentou associação negativa com a ocorrência de pausas em todas as etapas do teste. A variável gênero não apresentou nenhuma associação com a ocorrência de pausa em nenhuma das etapas do teste. Conclusão Com o aumento da idade, há um aumento na incidência de pausas na etapa de integração binaural do teste. Quanto mais anos de estudo menor a chance de o indivíduo necessitar de pausas para realizar o teste em todas as etapas de apresentação. A variável gênero não influenciou na ocorrência de pausas.

“…There are several objective and subjective behavioral and physiological measures sensitive to the amount of effort required for listening [58]. Delayed recall [23,76], dual-task procedures [56], perceived effort [25,55], ERPs [27,49,50] and cardiac measures63 have been used as indicators of listening effort.…”
