Title

DEFICIT OF AUDITORY TEMPORAL PROCESSING IN CHILDREN WITH DYSLEXIA-DYSGRAPHIA

Pages

  76-83

Abstract

 Background and Aim: AUDITORY TEMPORAL PROCESSING reveals an important aspect of auditory performance, in which a deficit can prevent the child from speaking, language learning and reading.Temporal resolution, which is a subgroup of temporal processing, can be evaluated by gap-in-noise detection test. Regarding the relation of AUDITORY TEMPORAL PROCESSING deficits and phonologic disorder of children with DYSLEXIA-dysgraphia, the aim of this study was to evaluate these children with the gapin-noise (GIN) test.Methods: The GAP-IN-NOISE TEST was performed on 28 normal and 24 dyslexic-dysgraphic children, at the age of 11-12 years old. Mean approximate threshold and percent of corrected answers were compared between the groups.Results: The mean approximate threshold and percent of corrected answers of the right and left ear had no significant difference between the groups (p>0.05). The mean approximate threshold of children with DYSLEXIA-dysgraphia (6.97 ms, SD=1.09) was significantly (p<0.001) more than that of the normal group (5.05 ms, SD=0.92). The mean related frequency of corrected answers (58.05, SD=4.98%) was less than normal group (69.97, SD=7.16%) (p<0.001).Conclusion: Abnormal temporal resolution was found in children with DYSLEXIA-dysgraphia based on GAP-IN-NOISE TEST. While the brainstem and auditory cortex are responsible for AUDITORY TEMPORAL PROCESSING, probably the structural and functional differences of these areas in normal and dyslexic-dysgraphic children lead to abnormal coding of auditory temporal information. As a result, AUDITORY TEMPORAL PROCESSING is inevitable.
