[ERA and dichotic test by Feldmann of dyslectic children (author's transl)]

Many elementary school-children (nearly 20%-for the West German Republic) have difficulties in reading and writing. In most cases these troubles will cease during the further school development, only very few must be classified as dyslectic. Dyslexia and its audiological problems was studied in over 100 children ranging from the age of 5-16 years. Hearing thresholds showed only in a few cases pathological results. The dichotic discrimination test by Feldmann revealed significant lower results compared with normal children and same age group. EEG audiometry (ERA) showed in over 30% of all dyslectic children a two phasic curve with two negative deflections. Most of these pathological curves could be separated into groups by superimposing them accordingly to the first and second negative deflection.
