Assessing Binaural Auditory Processing in Native Tamil Speaking Children

The objective of this study is to develop and validate the Binaural Fusion Test (BFT) in the Tamil language for children with learning disability. As many children with learning disability exhibit an auditory processing deficit there is a need for language specific assessment tool for these children. The BFT in Tamil comprises 100 words organized into four lists, with each list containing 25 words. A total of 84 children with normal auditory processing and 45 children diagnosed with learning difficulties were administrated the BFT in Tamil. Test-retest reliability was evaluated in a sample of 30 children who exhibited normal auditory processing. The results of BFT in children with normal auditory processing demonstrated satisfactory reliability by the Cronbach Alpha test. A statistically significant difference was seen in the mean scores of BFT in Tamil when comparing the groups. The present study offers novel normative data for the binaural fusion test in Tamil, which has not been previously documented in the existing literature. For children, the BFT in Tamil, which is a part of the CAPD test battery, can be used to find binaural interaction deficiencies.
