While persistence of subtle phonological deficits in dyslexic adults is well documented, deficit of categorical perception of phonemes has received little attention so far. We studied learning of phoneme categorization during an activation H(2)O(15) PET experiment in 14 dyslexic adults and 16 normal readers with similar age, handedness and performance IQ. Dyslexic subjects exhibited typical, ma...
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, rega...
Stress assignment to Italian polysyllabic words is unpredictable, because stress is neither marked nor predicted by rule. Stress assignment, especially to low frequency words, has been reported to be a function of stress dominance and stress neighbourhood. Two experiments investigate stress assignment in sixth-grade, skilled and dyslexic, readers. In Experiment 1, skilled readers were not affec...
The reading performance of two groups of dyslexic children with either a phonological (PH) or a visualattentional (VA) deficit was compared to that of control groups matched on chronological age (CA) and reading age (RA). In both groups and on all the reading measures, the dyslexic children performed worse than the CA-controls but similarly to the RA-controls. Performance of the VA dyslexic par...
In the pursuit of a remedy for the poor spelling of dyslexic writers, a software system has been developed which features centrally a user model of the writer’s spelling error patterns. Dyslexic writers are poorly catered for by most spelling programs because of their diverse errors. In this system, Babel, a user model directs the search towards likely corrections considering the writer’s commo...
The background noise of response times is often overlooked in scientific inquiries of cognitive performances. However, it is becoming widely acknowledged in psychology, medicine, physiology, physics, and beyond that temporal patterns of variability constitute a rich source of information. Here, we introduce two complexity measures (1/f scaling and recurrence quantification analysis) that employ...
In this paper we describe a connectionist model of the development of alphabetic spelling, and show that its performance resembles that of dyslexic spellers if its computational resources are restricted during learning. We then describe the results of an experiment which tests the predictions of the model on normal and dyslexic spellers. Our results suggest that dyslexic children show a similar...
________________________________________________________________________________________________________ Reading and prosody in dyslexic children, pause patterns Dyslexia is widely associated with a deficit in phonological awareness. Only few works in suprasegmental phonology showed that prosody is involved in the processes of decoding and reading comprehension. We developed a corpus (DySpoLec)...
We investigated crossmodal temporal performance in processing rapid sequential nonlinguistic events in developmentally dyslexic young adults (ages 20-36 years) and an age- and IQ-matched control group in audiotactile, visuotactile, and audiovisual combinations. Two methods were used for estimating 84% correct temporal acuity thresholds: temporal order judgment (TOJ) and temporal processing acui...
Abstract: We report the results of tasks that measured whether the syllable is a frequency-modulated prelexical and segmental unit available in French dyslexic children. Thirty-three French dyslexic children were compared to 66 chronological agematched and reading-level-matched controls. We designed a visual syllable detection task (Exp. 1), a visual masked priming paradigm (Exp. 2), and a revi...
