Central auditory processing disorder (CAPD), as defined by the American Speech-Language-Hearing Association (ASHA), refers to difficulties in the perceptual processing of auditory information in the central nervous system and the neurobiological activity that underlies that processing and gives rise to electrophysiologic auditory potentials (ASHA,…

Children with reading disability and normal reading development were compared in their ability to discriminate native (English) and novel language (Mandarin) from nonlinguistic sounds. Children's preference for native versus novel language sounds and for disyllables containing dominant trochaic versus non-dominant iambic stress patterns was also…

This study tested if children with specific language impairment (SLI) or children with specific reading disability (SRD) have abnormal brain responses to sounds. We tested 6- to 12-year-old children with SLI (N = 19), children with SRD (N = 55), and age-matched controls (N = 36) for their passive auditory event-related potentials (ERPs) to tones,…

Few studies have examined the ability of individuals with learning disabilities, in general, or with Down syndrome, specifically, to discriminate speech. The purpose of this study was compare the speech discrimination abilities of eight children with Down syndrome (aged 5.7 to 12.8 years) to seven nonverbal mental-age matched controls (aged 4.0 to…

Twelve children (4 1/2 to 8 1/2 years old) with normal language development, 12 normal adults, and 12 dysphasic children (6 to 9 years old) were tested for their ability to perceive binary sequences of nonverbal auditory stimuli. (Author/SBH)

Results of a study with 52 dyslexic children and 52 normal readers show that reading acceleration through computer-controlled reading rates improves reading performance in both groups, but auditory masking by playing a song is beneficial only to the dyslexic children. Implications are discussed in terms of phonological processing. (SLD)

Twenty-five dysfunctional (either autistic-like or with reading disorders) Ss ranging in age from 2 months to 25 years were studied to determine whether they respond to the same sound more than once. (Author/SB)

A proximal cause of reading disabilities is a deficit in phonological processing. A consequence of this deficit is inferior performance in one or more cognitive operations that use phonological information, including phonological awareness, lexical retrieval, and verbal memory. Some assert that these phonological processing difficulties are the…

This paper describes adult symptoms of Central Auditory Processing Disorder and provides strategies for dealing with this disability. Symptoms include talking or turning on the television louder than normal, interpreting words too literally, needing remarks repeated, having difficulty sounding out words, ignoring people, being unusually sensitive…

The origins and nature of auditory dysfunction in school age children and the role of the audiologist in the evaluation of the learning disabled child are reviewed. Specific structures and mechanisms responsible for the reception and perception of auditory signals are specified. (Author/SEW)

Methods to evaluate central hearing deficiencies and to localize brain damage are reviewed beginning with Bocca who showed that patients with temporal lobe tumors made significantly lower discrimination scores in the ear opposite the tumor when speech signals were distorted. Tests were devised to attempt to pinpoint brain damage on the basis of…

This book offers the latest available information on central auditory processing disorders (CAPDs) drawn from a State University of New York at Buffalo conference on CAPDs in September of 1996. It is divided into three parts: introduction, management approaches, and specific methods and populations. Chapters include: (1) "Overview and Update…
