In a masked cross-modal priming experiment with ERP recordings, spoken Japanese words were primed with words written in one of the two syllabary scripts of Japanese. An early priming effect, peaking at around 200ms after onset of the spoken word target, was seen in left lateral electrode sites for Katakana primes, and later effects were seen for both Hiragana and Katakana primes on the N400 ERP component. The early effect is thought to reflect the efficiency with which words in Katakana script make contact with sublexical phonological representations involved in spoken language comprehension, due to the particular way this script is used by Japanese readers. This demonstrates fast-acting influences of visual primes on the processing of auditory target words, and suggests that briefly presented visual primes can influence sublexical processing of auditory target words. The later N400 priming effects, on the other hand, most likely reflect cross-modal influences on activity at the level of whole-word phonology and semantics.

视觉素数对口语识别的快速调制

在使用 ERP 录音的屏蔽跨模态启动实验中，口语​​日语单词是用日语的两个音节脚本之一写的单词启动的。片假名素数的左侧电极位点出现了早期启动效应，在口语目标出现后约 200 毫秒达到峰值，而后期效应则在 N400 ERP 组件上的平假名和片假名素数中都能看到。早期效果被认为反映了片假名文字中的单词与口语理解中涉及的亚词汇语音表示接触的效率，这是由于日本读者使用这种文字的特殊方式。这证明了视觉素数对听觉目标词的处理的快速影响，并表明简要呈现的视觉素数可以影响听觉目标词的亚词汇处理。另一方面，后来的 N400 启动效应很可能反映了在全词音系和语义层面对活动的跨模态影响。
