While the role of morphology in alphabetic language processing has been extensively explored, it remains unclear how the human brain encodes the various aspects of morphological processing in Chinese word reading. This thesis focuses on the salience of Chinese morphological system and examined its brain bases by using electroencephalography (EEG) and functional near-infrared spectroscopy(fNIRS)data concurrently.The first experiment investigated the spatio-temporal brain activation patterns associated with morphological constraint encoding in reading single Chinese compound words. It was found from ERP data that semantic processing occurred earlier (N400, 300-450 ms) than morphological effect (LAN, 450-570 ms), while spatial activation pattern detected by fNIRS revealed a disassociation between the neural engagements of morphological parsing (the left IFG) and semantic analysis(the left temporal cortex including the MTG).The second experiment further inspected the temporal and spatial brain activities that are related to the morphological priming effect (compound/derivation constitute priming vs. non-morphological priming) and word structure (compound vs. derivation) modulation. Interestingly, morphological priming effect was mainly detected by the behavioral performance and spatial brain activation in the left prefrontal cortex. In addition, Chinese derivations exhibited significantly enhanced brain activation in the frontal cortex and involved more brain networks as compared to lexicalized compounds.The third experiment investigated the neural bases of morphological processing in bilingual population. FNIRS results revealed a neural dissociation between morphological and semantic priming in the left fronto-temporal network, while L1 Chinese engaged enhanced activation in the left prefrontal cortex for morphological parsing relative to L2 English. In the early stage of lexical processing, cross-language morphological processing manifested a difference in degree, not in kind, as revealed by early left anterior negativity (ELAN) effect. In addition, L1 andL2 shared both early and late structural parsing processes (P250 and 300~500 ms negativity, respectively).In conclusion, the three experiments collectively shed light upon the notion that morphology constitute an integral component in the human mental lexicon, which is independent of semantic representation.
