Abstract [en]

This study examined number processing in 10-year-olds with developmental dyslexia (DD). The, phonological deficit and double deficit hypotheses imply that children with DD might have a connection deficit that affects their ability to establish links between number symbols and magnitude representations. The double deficit hypothesis also posits that symbolic number difficulties may emerge due to difficulties with processes underlying rapid automatic naming (RAN). The DD group displayed difficulties with symbolic number processing but not with non-symbolic number processing. However, the underlying processes of this access or connection deficit appeared not to be related to phonological awareness or RAN. The DD group displayed impaired arithmetic fluency and calculation that were accounted for by defective processes. underlying RAN. In view of the triple-code model, children with DD have impaired-verbal number codes or defective access to verbal number codes but an intact core magnitude representation. (C) 2016 Elsevier Inc.
