Unlike visual and tactile stimuli, auditory signals that allow perception of timbre, pitch and localization are temporal. To process these, the auditory nervous system must either possess specialized neural machinery for analyzing temporal input, or transform the initial responses into patterns that are spatially distributed across its sensory epithelium. The former hypothesis, which postulates...

The present study attempted to study perception of time-compressed speech and the effect of compression ratio for phonemically balanced (PB) word lists in Kannada and monosyllables. The test was administered on 30 normal hearing individuals at compression ratios of 40%, 50%, 60%, 70% and 80% for PB words in Kannada and monosyllables. The results of the study showed that the speech identificatio...

In addition to aberrant features in the speech, children with Autism Spectrum Disorder (ASD) may present unusual responses to sensory stimuli, especially to auditory stimuli. We investigated the auditory ability of children with ASD by using Auditory Brainstem Responses (ABR) as they can directly judge both hearing status and the integrity of auditory brainstem pathways. One hundred twenty-one ...

PURPOSE To compare the performances of children with dyslexia and a control group in behavioral tests of (Central) Auditory Processing and Long Latency Auditory Evoked Potentials (P300). METHODS Participants were 22 individuals with dyslexia (study group) and 16 individuals with typical development (control group). All individuals underwent behavioral and electrophysiological assessment of (C...

A 17-item questionnaire probing professional preparation and current practices in central auditory assessment was mailed to 500 audiologists selected randomly from the membership directory of the American Academy of Audiology. Data from 183 respondents, representing a 37 percent response rate, were analyzed. The majority of respondents reported minimal academic and clinical preparation in asses...

Fragile X Syndrome (FXS), a neurodevelopmental disorder, is the most prevalent single-gene cause of autism spectrum disorder. Autism has been associated with impaired auditory processing, abnormalities in the auditory brainstem response (ABR), and reduced cell number and size in the auditory brainstem nuclei. FXS is characterized by elevated cortical responses to sound stimuli, with some eviden...
