The effectiveness of the auditory training in the central auditory processing disorder: a case study

[摘要] The objective of this study is to present the effectiveness of auditory training in the evaluation of a 9 year-old individual with a learning disorder, which have been evaluated through objective and behavioral tests, including audiometric test, imitanciometry, auditory brain response, P300 and central auditory processing evaluation. The diagnosis of Central Auditory Processing Disorder (CAPD) was confirmed by a normal performance on an audiometric test battery and an increased P300 latency time and the central auditory processing evaluation, which have shown the presence of a severe hearing processing disorder, characterized by the alteration of decoding, integration and memory process, and significant difficulties, particularly in selective attention and auditory closure. Auditory training to enhance development of the altered hearing abilities was conducted for four months. The progress observed in P300 latency time and the hearing processing disorder was still present but now at a moderate level at the end of the study. Also, this improvement was more significant in the integration process and showed an improvement in the auditory closure. It is concluded that the effectiveness of the auditory training through the development of the hearing abilities could be verified through the P300 and behavioral tests.
