Visual and Auditory Processing Disorders. By: National Center for Learning Disabilities (NCLD) Introduction Visual and auditory processing are the processes of recognizing and interpreting information taken in through the senses of sight and sound. The terms, "visual and auditory processing" and "visual and auditory perception", are often used interchangeably. Although there are many types of perception, the two most common areas of difficulty involved with a learning disability are visual and auditory perception. For the sake of consistency, the terms used in this packet are visual processing disorder and auditory processing disorder. Visual processing disorder What is it? A visual processing, or perceptual, disorder refers to a hindered ability to make sense of information taken in through the eyes.
Common areas of difficulty and some educational implications: Spatial relation This refers to the position of objects in space. Visual discrimination Visual closure Object recognition (Visual Agnosia) Whole/part relationships What is it? Listen up: Abnormality in auditory processing underlies dyslexia. People with dyslexia often struggle with the ability to accurately decode and identify what they read. Although disrupted processing of speech sounds has been implicated in the underlying pathology of dyslexia, the basis of this disruption and how it interferes with reading comprehension has not been fully explained. Now, new research published by Cell Press in the December 22 issue of the journal Neuron finds that a specific abnormality in the processing of auditory signals accounts for the main symptoms of dyslexia. "It is widely agreed that for a majority of dyslexic children, the main cause is related to a deficit in the processing of speech sounds," explains senior study author, Dr.

College of Allied Health - University of Oklahoma Health Sciences Center. The Central Auditory processing Disorders (CAPD) Clinic provides a multidisciplinary team approach to the assessment of school-age children and adults who are suspected of presenting higher-level language and/or auditory processing disorders. This team approach includes the following members and procedures: An audiologist will investigate the auditory skills and auditory system capability and provide the diagnosis. The classroom teacher or educational diagnostician will provide information concerning academic difficulties. A psychologist may evaluate cognitive functioning in a variety of different areas. The parent will provide information concerning the overall health, development, and interactions with family members and friends.
Other team members may be include as needed. The goal of the testing is to identify the strengths and weaknesses in auditory abilities for the individual and to determine if behavioral and academic symptoms represent a central auditory processing disorder.
