本研究以字彙判斷作業之方式，利用左右視區所呈現之促發作用，探討中文「字形」、「字音」與「字義」知識之腦側化現象。在實驗一中控制促發項和目標項之「字形」關係，實驗二中控制促發項和目標項之「字音」關係，而實驗三則控制促發項和目標項之「類目」關係，結果發現左視區呈現「字形」之促發作用，右視區則呈現「字音」與「字義」之促發作用，顯示右腦半球對於「字形」知識之觸接能力較強，對於「字音」與「字義」知識之觸接，則是左腦半球佔優勢。

The lexical decision paradigm was used to investigate the priming effect of Chinese character in both visual fields. Three lateralized lexical decision experiments employed various types of priming to distinguish the lateralization of lexical knowledge. The priming effect was obtained for orthographically similar stimuli, when the targets were presented to the left visual field. The priming effects based on phonological relatedness and semantic relatedness were obtained as the targets were presented to the right visual field. These results suggested that hemispheres utilize different lexical knowledge to achieve lexical access.
