Sophisticated neurological research shows that early problems with auditory perception can result in long-range negative effects for the linguistic processes in general, and such long-range effects must be assumed to be correlated with induced degenerative changes in the auditory system and perhaps in the brain's linguistic sector. This research also shows that the reading disabled (RDs) have a significantly different perception of auditory stimuli than normal readers and that dichotic listening reveals these differences. Normal readers can be differentiated from RDs by using binaural audiometry to measure ear advantage. The 62 references assist in documenting that ear advantage is a poor indicator of hemisphere dominance for language, but that it may be a neglected factor in the diagnosis of dyslexia. (RS)
