No studies have ever tried to demonstrate the nature of the issue with evidences in neurophysiology. We approach the issue by analyzing the records of Event-related brain potentials (ERP) in spoken word priming paradigm of 16 Taiwaneses. Our results elucidate the psychological processes that underlie the N400 component suggest the psychological reality of Southern-Min language tone sandhi and, in line with model of tone snadhi processing which assume that a dual-syllable whole word is a treatment unit during semantic comprehensive processing. Processing of tone sandhi in sentential context aside, however, for assignments, there still an unidirectional transform mechanism is working. Another, analysis of RP (recognition potential) shows that the minimum duration signal necessary to discriminate tone value of a spoken word is about 200ms after onset of stimuli, identified up to 300ms. After all, the implication of our results for the linguistic processes underlying the N400 is biphasic, not only associated with lexical access ( pre-lexical phonological analysis stage) but also post-lexical integration processes.
