A review of the importance of top-down processing assessment in auditory processing disorder

Abstract

Introduction: Auditory perception process is a transient phenomenon, which enables the person to make the relationship between events and auditory factor by working memory and obtain the sequence of auditory features and be able differentiate the auditory sources by using these component. In auditory processing, the basis formed by bottom - up process (data - driven). This pathway is dependent on the central auditory integration and also on acoustic signal input and interpreting auditory information is involved top-down process (concept - driven), which this pathway is dependent on central higher resource such as perception, attention, working memory and its span. The purpose of this study was to address information about top-down processing and auditory processing disorder. Materials and methods: A review of the latest literature on (central) auditory processing disorders and top-down processing was performed using PUBMED, EBSCO, SCIENCE DIRECT, ASHA, GOOGLE SCHOLAR, THIEME, PROQUEST data sources. Conclusion: Deficit in cognitive processing of auditory information in children cause difficulty in processing auditory information and outbreak auditory processing disorder symptoms. Cognitive evaluation (especially working memory) in this subject is important as bottom-up processing evaluation.
