Gliederung

Abstract

Dyslexia is a specific developmental impairment in the ability to read and spell despite adequate educational resources, an average intelligence quotient, no sensory deficits and appropriate social and cultural opportunity. A number of findings point to an organic etiology of the disorder. An atypical organization of the auditory cortex in dyslexic readers could be demonstrated. On a functional level the core deficit in dyslexia is assumed to reading decoding processes. Problems with auditory attention, concentration, analysis are observed. Phonological deficits are very common theory now. Auditory processing and reading disorders have been linked in a number of studies. One way to delineate the cognitive difficulties associated with developmental dyslexia is the use of event-related brain potentials (ERPs). Thanks to them it is possible to analyze information of processing reactions.

The aim of the study were to observe ERPs in dyslectic children, to determine the presence of auditory processing disorders and to investigate the differences in dyslectic children taking into consideration age, sex, intensity of cognitive difficulties described by psychologists, and also duration of rehabilitation process.

Subjects were aged 7-18, had no history of hearing problems with normal hearing threshold. Each child suffered from dyslexia. Electric evoked potentials were preformed. Event-related potentials (ERPs) particularly MMN and P300 were in the special interest. The results will be discussed.
