Abstract: Two experiments were conducted to examine the effects of polysemy in the identification of Chinese two-character words in the lexical decision tasks. In experiment 1, with a filler word(e.g.,镜社)consisting of two Chinese characters ranged randomly, a polysemous advantage effects was observed only in the error rates. In Experiment 2, however, with a filler word(e.g.,冲烽)as composed of two Chinese characters which were pseudohomophonetic and similar-graph with the two Chinese characters forming a polysemous word(e.g.,冲锋), there were a robust polysemous advantage effects mainly in low frequent words and a significant interaction between polysemy and frequency. The results of two experiments showed that when different foils were used in the lexical decision tasks, subjects adopted different strategies in the different foils contexts, and acceded to the different semantic levels of words. The implications of these results for conclusions were best accounted for in terms of the the feedback accounts.
