چکیده

We analyzed phonological and visual information processes of four Japanese dyslexic children between 710 years of age. None of them had disability in word retrieval and/or auditory memory. Two of them manifested lower score in phonological awareness tests while the others showed normal score. All children showed subnormal score in a visual cognitive test, a visuo-spacial constructional test, and a visual long-term memory test. 90 % of their errors were formal ones. As results, these four Japanese dyslexic children are thought to have disabilities in visual information processes and are thought to be of a different type from those reported as phonological dyslexia.

Paradoxically, Japanese children have serious difficulty analysing phonological processes when they have dyslexia. Neurobiological deficits in Japanese dyslexia remain unclear and need to be identified, and may lead to better understanding of the commonality an...

Phonological skills, visual attention span, and visual stress in developmental dyslexia.

In this study, we concurrently investigated 3 possible causes of dyslexia-a phonological deficit, visual stress, and a reduced visual attention span-in a large population of 164 dyslexic and 118 control French children, aged between 8 and 13 years old. We found that most dyslexic children showed a phonological deficit, either in terms of response accuracy (92.1% of the sample), speed (84.8%), o...

The dyslexic children showed deficits in most of the skills, with fundamental deficits (worse performance than reading age controls) on phonological skill, naming speed, bead threading, and on some balance tasks. Furthermore, there was...
