Experiments previously reported in the literature suggest that people with dyslexia have a deficit categorical perception. However, it is still unclear whether specific to perception of speech sounds or more generally affects auditory function. In order investigate relationship between and dyslexia, as well nature this categorization deficit, not, discrimination responses children who those average readers sinewave analogues were compared. These presented two different conditions, either...
Phonological dyslexics (Ph-DYS) are characterized by a phonological deficit, while surface (S-DYS) an orthographic deficit. Four issues were addressed in this study. First, we determined the proportion of Ph-DYS and S-DYS population French applying Castles Coltheart's (1993) regression method to two previously unused diagnostic measures: pseudo-word irregular-word processing time. Thirty-one matched 19 average readers same age (10 years, CA controls) younger children reading level (8 RL...
Speech perception in dyslexia is characterized by a categorical (CP) deficit, demonstrated weaker discrimination of acoustic differences between phonemic categories conjunction with better within categories. We performed meta-analysis studies that examined the reliability CP deficit dyslexia. The results show reliable individuals compared to both chronological-age and reading-level controls. stronger for than identification, suggesting latter may only reveal between-category do not fully...
The present study investigates the perception of phonological features in French-speaking children with cochlear implants (CIs) compared normal-hearing (NH) matched for listening age.Scores discrimination and identification minimal pairs all defining consonants (e.g., place, voicing, manner, nasality) vowels frontness, nasality, aperture) were measured each listener.The results indicated no differences "categorical perception," specified as a similar difference between CI controls. However,...
We tested the hypothesis that categorical perception deficit of speech sounds in developmental dyslexia is related to phoneme awareness skills, whereas a visual attention (VA) span constitutes an independent deficit. Phoneme tasks, VA tasks and identification discrimination using d/t voicing continuum were administered 63 dyslexic children control matched on chronological age. Results showed significant differences between children. Significant correlations found reading. Although correlated...
Categorical perception of phonemes and visual-attention span are cognitive processes that contribute independently to poor reading skills in developmental dyslexia. We here explored whether training programs specifically targeting one or the other process do improve performance dyslexic children. The participants were trained using either RapDys program designed phonemic MAEVA visual attention span. Each participant was provided two successively for intensive training. Results show...
To investigate the capacity of young children and adults with normal hearing to discriminate speech on basis either relatively slow (temporal envelope, E) or fast fine structure, TFS) auditory cues.Vowel-consonant-vowel nonsense disyllables were processed preserve E TFS information in 16 adjacent frequency bands. The band signals then recombined resulting stimuli presented for discrimination 5-, 6-, 7-year-old using an odd-ball paradigm. Discrimination scores (d') response latencies measured...
The aim of the present study was to evaluate impact literacy on phoneme perception. It built previous research by using more controlled stimuli than in former studies and independently examining impacts age Participants were adult children beginning readers, skilled readers. They presented with identification discrimination tasks, a voicing continuum. In addition their categorical perception speech sounds precision phonemic categories, participants' level carefully evaluated. results...
