Mechanisms of Japanese and English Lexical Information Processing and Language Learning

词汇层面的三项信息--正字法、音位和意义--以一种复杂的方式交织在一起。本研究的目的是揭示日语书面语中词汇信息加工的某些方面。已经处理了六个主题。首先，测量了汉字中双字词和非字词的词汇决定潜伏期，并观察了配价效应。其次，测量了高频汉字和低频汉字的事件相关电位，发现高频有意义汉字的事件相关电位为N400。第三，使用汉字和假名的命名潜伏期，考察了词义和音韵的时间进程。第四，对山崎等人(1997年)S的命名潜伏期数据进行了再分析。第五，对国家语言研究所1988年的数据进行了重新分析，重点分析了初中生和高中生的错误模式。最后，比较了两读汉字和一读汉字的命名潜伏期。

Three items of information at the lexical level, orthography, phonology, and meaning, are entwined in a complicated manner. The goal of this study is to reveal some aspects of lexical information processing in written Japanese. Six topics have been dealt with. First, lexical decision latencies were measured for two-character words and nonwords in kanji, and the effect of valence was observed. Second, event-related potentials were measured for high-and low-frequency kanji characters, and N400 was found for high-frequency meaningful characters. Third, a time course for meaning and phonology was investigated, using naming latencies for kanji and kana. Fourth, the Yamazaki et al.'s (1997) data for naming latencies were reanalyzed in terms of ease of acquisition. Fifth, the National Language Institute's (1988) data were reanalyzed, focusing on error patterns for middle and high school students. Finally, naming latencies were compared between kanji with two readings and those with one reading.
