Purpose: To study auditory temporal processing performance in 30 children with stuttering (CWS) and compare it with 30 age -matched controls. Materials and Methods: Auditory temporal processing was compared in two groups of children: With and without stuttering; in the age -range of 9 -14 years using Gap Detection Test (GDT) and Duration Pattern Test (DPT). Ear differences in the gap detection thresholds and duration pattern scores were also studied in both the groups. GDT was carried out using the GDT CD developed by Shivprakash and Manjula (2003) and DPT was carried out using the DPT CD developed by Gauri and Manjula (2003). Results: No significant difference was seen in the gap detection thresholds and DPT scores between the right ear and left ear scores in typical children and between the scores of the two ears in CWS. The performance of CWS group was significantly poorer as compared to that of typical children in both GDT and DPT. These auditory temporal processing deficits may interfere with the auditory feedback loop that is crucial to fluent speech production. Fluency inducing conditions like slow reading, DAF, or frequency -altered feedback reduce the dependence on auditory feedback thus inducing fluent speech. The results of the present study show that deficient auditory temporal processing in CWS may add to the demands placed on the feedback mechanism thereby increasing stuttering. Conclusions: As a group, CWS show evidence of compromise in their auditory temporal processing abilities. Tests of temporal processing should be included in assessment of IWS as a pre-therapy assessment tool along with assessment of stuttering.
