Previous research has revealed that dyslexic children may be more sensitive to backward-masking effects in auditory perception than control children. In this study, we asked whether a CV transition masks a preceding VC transition to a greater extent in dyslexic children than in controls. The results suggest that dyslexic children are severely impaired on the discrimination of VC sequences, regardless of whether these sequences are followed or not by a CV sequence. These results provide further evidence that dyslexia is associated with a deficit in the perception of speech.
