Dychotic Rhyme Test in Kannada: A Normative Data on Adults

Abstract

Dichotic speech tests proved to have high sensitivity in assessing binaural integration tasks that often noticed in individuals having CAPD. Research focusing on Dichotic Rhyme test has been relatively scanty. The present study aimed to develop one such test and to collect normative data on kannada speaking normal hearing individuals. Stimulus was developed using 18 pair of cvcv rhyming words that differ only in initial consonants. These stimuli were made similar in total duration and imposed on to stereo tracks and aligned in such a way that there was no onset delay between the two. Normative data was established on young normal hearing kannada speaking adults. Analysis of results revealed that there existed a significant right ear advantage for the dichotic stimuli. Females had greater mean ear correct scores as compared to males for both right and left ears. Females had greater men double correct scores as compared to males. The double correct scores were found to be lower when compared to the ear correct scores.
