Testing the automatization deficit hypothesis of dyslexia via a dual-task paradigm.

Fourteen children with dyslexia were compared with controls matched for age and reading age on automatic processing under a dual-task paradigm. The primary task was a motor balance one, and the secondary task was an auditory-choice task. Main results show that the dyslexic group was more impaired in the dual-task condition compared to the single-task condition. The findings support the automatization deficit hypothesis of dyslexia.
