Development of Dichotic Word Test in Tamil Speaking Children

Anitha Selvaraj, Ranjith Rajeswaran, and Deepika Jayachandran

Abstract

Objective

The present study was aimed to developing dichotic word test in Tamil speaking children and also to generate the normative data. The word list consists of two different sets of lists, each list containing 25 pairs of monosyllabic words. These word pairs have equal duration and aligned in such a way that both words were presented simultaneously in both ears.

Method

The Data were administered from 100 children between the age ranges of 7-12 years. Each group consists of 20 participants with 10 males and 10 females.

Analysis

Responses were scored in terms of single correct scores (right correct score and left correct score) and double correct scores.

Results

The results revealed that there was an improvement in the single and double correct scores for both Lists I and List II with an increase in age. The mean scores for right correct score and left correct score for both the lists, right ear scores were greater, compared to left ear scores and double correct scores. This indicates the Right Ear Advantage (REA). However, there was no significant difference between list and gender.

Conclusion

The developed dichotic word test in Tamil can be used clinically as diagnostic tool to assess the auditory processing disorder in Tamil speaking children between 7years to 12.11 years of age.

Keywords: Dichotic Word Test in Tamil Speaking Children, Dichotic, Right Ear Advantage, Double correct score, auditory processing.

Introduction

Central auditory processing is described as “what we do with what we hear” (Katz, Steeler & Henderson, 1992). Auditory processing disorders (APDs) refer to problems in the perceptual processing of auditory information at the level of central auditory nervous system as demonstrated by difficulties some aspects such as sound localization, lateralization, auditory discrimination, temporal aspects of audition, auditory pattern recognition, auditory performance in competing acoustic signal, and auditory performance in degraded acoustic signal (American Speech - Language -Hearing Association [ASHA] 2005).

CAPD is also frequently a component of the aging process (American Academy of Audiology [AAA] 2010). About two to three percent of children, with a 2:1 ratio between boys and girls (Chermak & Musiek, 1997). It is also estimated that CAPD occurs in 10 to 20% of adults (Cooper & Gates, 1991). Patients with APD frequently experience unusual difficulty hearing or understanding speech in various adverse acoustic and listening situations, such as listening to distorted or rapid speech, or hearing in noisy or reverberant environments, even though normal-hearing thresholds. One very common complaint of APD is difficulty hearing in the presence of noise (AAA, 2010).
