Inside School Research: Study Suggests Dyslexia Varies Around the Globe:
"Dyslexia looks distinctly different in Chinese speakers than it does in American children, a new study says."
In the U.S., children who are dyslexic have trouble detecting or manipulating the sound structure of oral language, according to a report on the study posted this week in the "Science Daily" blog, and that, in turn, leads to problems mapping speech sounds onto letters.
In China, though, dyslexia is both a phonological problem and a visuospatial disorder, says this group of researchers from the University of Hong Kong. That's due in part to structural differences in the languages. They write:
"Written Chinese maps graphic forms—i.e., characters—onto meanings. Chinese characters possess a number of intricate strokes packed into a square configuration, and their pronounciation must be memorized by rote."
That means the Chinese readers must rely more heavily on visuospatial processing than do readers of English. To test that idea, the researchers asked normal and dyslexic Chinese readers to judge the size of visual stimuli. In keeping with their theory, they found that nondisabled readers excelled at that task.
