Abstract

Abstract

Based on studies in English speakers, it has been proposed that speech-evoked brainstem responses (ABRs) may be used clinically to assess central auditory function. Whether the same procedure can be used across speakers of different languages remains unclear, because recent findings suggest that language experience affects even subcortical processing of speech. The goal of the present study was to characterize brainstem responses to the syllable /da/ in Arabic and Hebrew speakers using the US developed BioMARK procedure. To that end, ABRs evoked by clicks and the syllable /da/ were collected from 37 normal-hearing students from the University of Haifa. Neither the transient nor the sustained components of the brainstem response differed significantly between Arabic and Hebrew speakers. Across the two groups, timing of the major components of the speech-evoked response as well as the correlations between the speech- and click indices were well within the US norms. Therefore, brainstem processing of the syllable /da/ does not differ between speakers of English and speakers of Semitic languages such as Arabic and Hebrew.

Sumario

Con base en los estudios realizados en hablantes del inglés se ha propuesto que las respuestas del tallo cerebral evocadas por lenguaje (ABR) pueden utilizarse clínicamente para evaluar la función auditiva central. Aun no queda claro si el mismo procedimiento puede utilizarse (transversalmente) entre los hablantes de diferentes lenguas ya que algunos hallazgos recientes sugieren que la experiencia lingüística afecta incluso el procesamiento subcortical del lenguaje. El objetivo del presente estudio fue caracterizar las respuestas del tallo cerebral ante la sílaba /da/ en hablantes del árabe y el hebreo utilizando el procedimiento BioMARK desarrollado en EUA. Para tal fin, se colectaron respuestas de ABR evocadas por clicks y por la sílaba /da/ de 37 estudiantes normoyentes de la Universidad de Haifa. Ni los componentes basales ni los transitorios de las respuestas evocadas difirieron significativamente entre los hablantes del árabe y del hebreo. A través de los dos grupos la temporalidad de los componentes mayores de las respuestas evocadas por lenguaje así como la correlación entre los índices con lenguaje y con clicks estuvieron dentro de las normas de los EUA. Por lo tanto, el procesamiento del tallo cerebral de la sílaba /da/ no difiere entre los hablantes del inglés y los hablantes de las lenguas semíticas como el árabe y el hebreo.
