Abstract
Central auditory processing disorder (CAPD) is a deficit in one or more of the central auditory processes. These processes include sound localization and lateralization, auditory discrimination and pattern recognition, auditory temporal processing, auditory performance with degraded acoustic signals and auditory performance with competing acoustic signals (ASHA, 1996). Many other neurocognitive mechanisms are deployed in the processing of acoustic signals such as memory and attention (Jerger and Musiek, 2000). Furthermore, the interhemispheric transfer is an important neural process that helps integration of auditory processes across hemispheres (Musiek, 1999). Central auditory processing disorders have been casually linked to developmental language disorders. Moreover, they are responsible for a relatively high percentage of learning disability among school children.
Temporal aspects of auditory processing have received much attention, since it was claimed that children with developmental language problems have difficulties in discriminating pairs of complex tones differing only in fundamental frequency when presented in rapid succession (Tallal, 1980). Accordingly, direct skill remediation for the affected abilities was considered the most important line of management (Bellis, 1996, ASHA, 2005).
The objective of the current study was to evaluate the performance and to standardize the developed Arabic computer-based remediation program for central auditory processing disorders. The program was standardized on 60 normal children ranging in age from 5-12 years. The results showed improvement in the scores of these games with increase age in normal children. Meanwhile, the performance of normal children was not affected by the gender and I.Q. Socioeconomic level has a significant effect on the performance of normal children in game II. There was significant effect of change frequency pair in game I and II, with no effect of change frequency in game III and IV.
