Abstract

The purpose of the current study was to investigate whether phonological information of the visually presented word is activated before lexical access. To do so, the present study compared ERPs of the irregular words and regular words. Since N320 component has been known as an ERP component reflecting grapheme to phoneme conversion, we would expect different N320 waves between irregular and regular words if phonological information is activated before lexical access. As expected, the results showed larger N320 for irregular words than regular words. The present study supported the idea that phonological information is activated from the sublexical level during visual word recognition processing.
