Abstract

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.
