摘要	An experiment was conducted to examine the hemispheric dominance in semantic processing of Chinese characters. Results showed that NI is the earliest component that reflects the semantic processing of Chinese characters. Although NI of the left hemisphere is larger in amplitude, that of the right hemisphere is shorter in latency. Based on these findings, the authors propose that the left hemisphere does not start processing until the necessary information has been transferred from the right hemisphere. Once the left hemisphere starts processing, its intensity is stronger. Thus, it is more appropriate to differentiate hemispheric processing dominance into two dimensions: speed and intensity. Moreover, the semantic cognition onset of Chinese characters occurs from 100 ms to 160 ms in the posterior perceptual processing area of brain.; An experiment was conducted to examine the hemispheric dominance in semantic processing of Chinese characters.
