However, our previous studies demonstrated that print-specific N170 for transparent Japanese Hiragana script consists of at least two subcomponents under rapid stimulus presentation: an attention-related left-lateralized N170 and a bilateral N170 associated with more automatic orthographic processes (Okumura, Kasai & Murohashi, 2014, 2015). The present study aimed to confirm the latter component by controlling presentation frequency of letters and nonlinguistic visual controls (i.e., symbols), but found a quite different pattern of results; an enhanced occipito-temporal positivity for words (80-120 ms poststimulus) followed by the typical left-lateralized N170 and an enhanced parietal negativity for nonwords (150-200 ms). These results should provide further insights into the interaction processes between attention and early stages of print processing.Elsevier2017-05-22engjournal articleAMhttp://hdl.handle.net/2115/73709https://doi.org/10.1016/j.neulet.2017.04.020284125330304-3940AA00754925Neuroscience letters6507781https://eprints.lib.hokudai.ac.jp/dspace/bitstream/2115/73709/1/uno_NSL_sumbit_rev2.pdfapplication/pdf810.89 KB2017-05-22
