Cerebral lateralization of bilingual functions after handedness switch in childhood.
Chinese-English bilingual undergraduates who had been forced to switch their preferred hand from the left to the right during childhood were identified. In hemifield perception of Chinese and English words, ordinary left-handers and handedness-switch subjects showed a less strong left-hemisphere advantage when compared with right-handers. The latter showed a significant superiority in identifying words presented in the right visual field. Handedness switch during early childhood did not seem to affect lateralization of language functions, although other motor functions may be affected.
