Perception catégorielle et autres compétences phonologiques : pertinence pour l'évaluation de la dyslexie

Abstract : The aim of the present study is to evaluate the relevance of subtests measuring syntagmatic categorical perception as well as other phonological skills associated with reading (phonological awareness, rapid automatized naming and working memory). We elaborated a protocol, which we proposed to 62 children who served as our control group, 14 dyslexics of the same age and 32 older dyslexics with the same reading level. We found that dyslexics, including those with the same reading level as the control group, display an atypical categorical identification slope, related to allophonic perception (i.e. the over-discrimination of intraphonemic differences). Subtests assessing other phonological skills and reading, in particular isolated words and pseudowords, also revealed deficits specific to dyslexics. Discriminant analyses allowed us to determine the most relevant subtests to be included in a battery of written language assessments. In particular, they bring out the one pertaining to categorical perception. However, the inclusion of this last subtest into the battery is currently hampered by technological constraints.
