OBJECTIVE: It has been claimed that @entity1 with @entity5545 show @entity1650 and a training of auditory perception is recommended as a therapy. this study addresses the question whether a causal connection between auditory perception and @entity5545 can be proven empirically. METHOD: 27 dyslexic @entity1 with average intelligence and normal hearing and 31 controls were examined. The auditory perception ability was judged with non-linguistic (pitch, tone duration, sound discrimination tasks) and verbal (speech in noise, compressed speech) tasks. In addition auditory short-term memory, nonverbal IQ, spelling and language ability were assessed. RESULTS: Group differences were found in tone processing tasks, but not in sound discrimination or auditory verbal tasks. Despite significant main effects in tone processing tasks the individual values of the dyslexic @entity1 lay predominantly in the range of the controls. In addition, there was no correlation between tone processing and spelling ability. CONCLUSION: Dyslexic @entity1 do not show remarkable @entity1650 . Auditory low level deficits can only be observed within a small subgroup. There is no evidence for @entity29175 as a cause of @entity5545 . The relevance of auditory processing training for treatment programmes for @entity5545 should be questioned.
