Research on Developmental Dyslexia in Chinese

The paper summarized the studies of developmental dyslexia of Chinese school child. The lexical processing of reading disability children was discussed and the relationship between Chinese reading and some cognitive processes, especially basic visual perception, was also examined. It was argued that there was a regularity effect of developmental dyslexia in Chinese character recognition. Children with reading disability tended to rely more on phonological code in access to semantic than the control group, reflecting their difficulty in lexical processing. Subjects suffering developmental dyslexia took more time in naming both Chinese characters and numbers. It was also found that the dynamic motion detection threshold accounted for about 25% differences in orthographic similarity judgement.
