Previous studies have shown that children suffering from developmental dyslexia have a deficit in categorical perception of speech sounds. The aim of the current study was to better understand the nature of this categorical perception deficit. In this study, categorical perception skills of children with dyslexia were compared with those of chronological(More)
PURPOSE This study investigated whether adults with dyslexia show evidence of a consistent speech perception deficit by testing phoneme categorization and word perception in noise. METHOD Seventeen adults with dyslexia and 20 average readers underwent a test battery including standardized reading, language and phonological awareness tests, and tests of(More)
Language and literacy are cognitive skills of exceptional complexity. It is therefore not surprising that they are at risk of impairment either during development or as a result of damage (e.g. stroke) later in life. Impaired language and literacy can arise from a general learning impairment. However, two developmental disorders, specific language(More)
PURPOSE The claim that speech perception abilities are impaired in dyslexia was investigated in a group of 62 children with dyslexia and 51 average readers matched in age. METHOD To test whether there was robust evidence of speech perception deficits in children with dyslexia, speech perception in noise and quiet was measured using 8 different tasks(More)
In a previous experiment, we showed that the vowel-vowel token [ai] is perceived by adult French listeners as / ai/ for transition durations between the 2 vowels lesser than 200 ms (50% of the response) and as /αΕι/ for larger durations. Recall that the /ai/ formant trajectory in the F1-F2 plane crosses the region of the vowel /Ε/. Further, the 200 ms(More)
PURPOSE In this study, the authors aimed to determine whether children with dyslexia (hereafter referred to as "DYS children") are more affected than children with average reading ability (hereafter referred to as "AR children") by talker and intonation variability when perceiving speech in noise. METHOD Thirty-four DYS and 25 AR children were tested on(More)
