Commentary Brain-behavior relations in reading and dyslexia: Implications of Chinese results

By Charles A. Perfetti A, Li Hai Tan B and Wai Ting Siok B


It is ironic that our recent report on the neural correlates of Chinese dyslexia (Siok, Perfetti, Jin, & Tan, 2004) raises a concern by Ziegler (2006) that this report could undermine an agreed-upon conclusion favoring a phonological deficit as the cause of reading disability. Our past research over 20 years in English (Perfetti, 1985) and Chinese (Perfetti, Liu, & Tan, 2005; Pollatsek, Tan, & Rayner, 2000; Tan & Perfetti, 1998) has argued that phonological processes are intrinsic to word reading and universal across writing systems, and we certainly have no reason to minimize the importance of these processes for understanding reading disability. We address Ziegler’s concern by making two observations.
