ABSTRACT
Abstract

Introduction:

Tinnitus is a central auditory disorder in which different processing systems are involved as a network. One of these networks is memory. Previous studies have demonstrated some deficits in various types of memory in chronic tinnitus.

Objectives:

The main purpose of the present study was to investigate the semantic memory, which is not yet investigated in the tinnitus population.

Methods:

In this case-control study, 15 subjects with chronic tinnitus and 16 matched healthy controls were included. 40 semantically related and 40 semantically unrelated word pairs were presented to the participants in a counter-balanced fashion. They were asked to make decision about their semantic relatedness. Then the participants' reaction times and the accuracy of responses were calculated.

Results:

Mean of reaction times were significantly longer in the tinnitus group (M = 1034 ms, SD = 0.31) compared to the control group (Mean = 1016 ms, SD = 0.13), p < 0.05. However, no significant difference was found for the mean percentage of correct responses between the two groups.

Conclusion:

The current study provided behavioral evidence that chronic tinnitus can affect the semantic memory. Such behavioral outcomes may provide new insights into more research activities in the field of electrophysiology and neuroimaging in the tinnitus population.
RESUMO
Resumo

Introdução:

O zumbido é um distúrbio auditivo central, no qual diferentes sistemas de processamento estão envolvidos como em uma rede. Uma dessas redes é a memória. Estudos anteriores demonstraram alguns déficits em vários tipos de memória no zumbido crônico.

Objetivos:

Investigar a memória semântica, que ainda não foi investigada na população com zumbido.

Método:

Neste estudo de caso-controle, 15 indivíduos com zumbido crônico e 16 controles saudáveis pareados foram incluídos; 40 pares de palavras semanticamente relacionados e 40 semanticamente não relacionados foram apresentados aos participantes de forma contrabalançada. Eles foram instruídos a tomar decisões sobre sua relação semântica. Em seguida, os tempos de reação dos participantes e a precisão das respostas foram calculados.

Resultados:

A média dos tempos de reação foi significativamente maior no grupo com zumbido (M = 1,034 ms, DP = 0,31) em comparação ao grupo controle (média = 1,016 ms, DP = 0,13), p< 0,05. Entretanto, nenhuma diferença significante foi encontrada para a porcentagem média de respostas corretas entre os dois grupos.

Conclusão:

O presente estudo forneceu evidências comportamentais de que o zumbido crônico pode afetar a memória semântica. Tais resultados comportamentais podem levar a novas percepções em mais atividades de pesquisa no campo da eletrofisiologia e neuroimagem na população com zumbido.
