This study was designed to examine how Chinese learners of Japanese in an advanced class process Kanji-words under the condition of pre-presentation of Japanese sentence. In the experiment based on Schwartz & Kroll (2006), the participants were required to read Japanese sentence and read orally Japanese words (Kanji or Katakana words). Reaction times in oral-reading of the words were measured as dependent variables. Form and phonological similarities between Chinese and Japanese words, and sentence constraints were operated as independent variables. The results showed that constraints of sentences influence processing of Japanese words differently according to the types of words. The facilitatory effect of form similarity was observed regardless of the sentence constraints. It was suggested that both of Japanese and Chinese form representations and concept representation (meaning) were simultaneously activated in processing of Japanese Kanji-words.
