In my Event-Related Potential studies, these two factors are analyzed collectively. Two dichotic listening experiments, one word phonological priming experiment, and one sentence semantic violation experiment are conducted. The results indicate that the linguistic role (e.g. semantics) causes the tone processing toward the left side, whereas the physical property causes the tone processing toward the right side.In this dissertation, I discuss the effects of the linguistic role and the physical property on the hemispheric specialization (lateralization) of the lexical tones. In the previous studies of lateralization, there are two contradictory hypotheses. One emphasizes the linguistic role and predicts a left lateralization of tone perception, while the other emphasizes the physical property and predicts a right lateralization of tone perception. Both hypotheses have their supporting evidence.No previous tone lateralization studies have analyzed the underlying factors. Following the philosophy that language is built upon multiple cognitive functions, I further examine the effects of semantic memory and pitch processing on the lateralization of tones in various language tasks. My findings help bridge the previous theoretical discrepancies and unify the conflicting experimental results regarding tone lateralization.Shuai, LanAdviser: William S-Y.
