Hearing Loss and Auditory Processing Disorders: Clinical and Experimental Perspectives
This chapter focuses on hearing loss and auditory processing disorders (APD) with reference to culture and identity. Hearing impairments constitute a world-wide problem. They affect both language communication and social interactions, and hence, influence personal identity. APD are discussed from both audiological and neuropsychological perspectives. We present demographic data on hearing impairment and the most important methods applied to assessment and treatment of hearing disorders. We also discuss major cognitive deficits associated with hearing impairments across the life span and their psycho-social consequences. We also emphasize the importance of temporal aspects of auditory information processing which are crucial for broad aspects of cognitive function with special reference to language communication and learning ability. The reviewed literature data are illustrated with some results from our studies indicating psychophysical, electrophysiological and neuroimaging correlates of temporal processing after application of Fast ForWord training.
