The objective was to determine whether mismatch negativity (MMN) is suitable to supplement subjective psychometric subtests of central hearing. We assessed 13 healthy children and 32 children with central auditory processing disorder (CAPD). Three different types of sound deviants were presented in a multi-deviant MMN design. At group level, the incidence of MMN was always higher in clinically ...

The term 'central auditory processing disorder' (CAPD; in German-speaking countries: 'auditive Verarbeitungs- und Wahrnehmungsstörung', AVWS) embraces various complex disorders of central auditory function. The purpose of this preliminary study was to develop a functional magnetic resonance imaging (fMRI) test set in order to extend the diagnostic work-up to include imaging, and thus to improve...

The purpose of this study was to quantify how the use of two different cutoff criteria affects the test failure rate and potential diagnosis of central auditory processing disorder ([C]APD) in a sample of children subjected to central auditory processing ([C]AP) assessment. Test failure rates for the central test battery (CTB) using two different cutoff criteria (1 and 2 SDs below the mean) wer...

BACKGROUND: Psychoacoustics is a fascinating developing field concerned with the evaluation of the hearing sensation as an outcome of a sound or speech stimulus. Neuroaudiology with electrophysiologic testing, records the electrical activity of the auditory pathways, extending from the 8th cranial nerve up to the cortical auditory centers as a result of external auditory stimuli. Central Audito...

Language processing from the cochlea to auditory association cortices shows side-dependent specificities with an apparent left hemispheric dominance. The aim of this article was to propose to nonspeech specialists a didactic review of two complementary theories about hemispheric asymmetry in speech processing. Starting from anatomico-physiological and clinical observations of auditory asymmetry...
