We present an MEG study of heteronym recognition, aiming to distinguish between two theories of lexical access: the 'early access' theory, which entails that lexical access occurs at early (pre 200 ms) stages of processing, and the 'late access' theory, which interprets this early activity as orthographic word-form identification rather than genuine lexical access. A correlational analysis method was employed to examine effects of the heteronyms' form and lexical properties on brain activity. We find support for the 'late access' view, in that lexical properties did not affect processing until after 300 ms, while earlier activation was primarily modulated by orthographic form.
我们展示了一项关于异形词识别的脑磁图（MEG）研究，旨在区分两种词汇通达理论：“早期通达”理论，该理论认为词汇通达发生在加工的早期（200毫秒之前）阶段；以及“晚期通达”理论，该理论将这种早期活动解释为正字法单词形式识别，而非真正的词汇通达。我们采用了一种相关分析方法来检验异形词的形式和词汇属性对大脑活动的影响。我们发现支持“晚期通达”观点，即词汇属性直到300毫秒之后才影响加工，而早期激活主要受正字法形式的调节。
