Auditory temporal processing and dyslexia in an orthographically consistent language

We examined two hypotheses relating auditory processing to dyslexia in Greek an orthographically consistent language Study I examined the P center or beat detection hypothesis (Goswami et al 2002) in a sample of Grade 6 dyslexics Grade 6 chronological age (CA) controls and Grade 4 reading age (RA) controls Study II examined the temporal processing or rapid auditory processing hypothesis (Tallal 1980) in a sample of Grade 7 dyslexics CA controls and in two groups of CA matched children with low frequency discrimination or low tone sequencing performance Both studies indicate that (a) as a group dyslexic children did not perform significantly worse on auditory processing measures than the control groups (b) measures of auditory processing mostly did not account for unique amount of variance in phonological processing reading or spelling and (c) at an individual level of analysis some of the dyslexic children experienced auditory temporal processing deficits Implications on the importance of auditory processing in reading in orthographically consistent languages are discussed (C) 2010 Elsevier Srl All rights reserved
