The consonant/vowel pattern determines the structure of orthographic representations in the left fusiform gyrus

PUBLISHED STUDY. Recent findings demonstrated readers’ sensitivity to the distinction between consonant and vowel (CV) letters. Especially, the way consonants and vowels are organised within written words determines their perceptual structure. One consequence of these results is the need to revise current models of visual word recognition. Before tackling such a challenge, two further assumptions need to be tested, namely, first, that effects of CV structure occur at an early stage during letter string processing, and second, that the CV pattern determines the units at one level in the hierarchy of neural detectors coding orthography. The aim of the paper is to directly test these two claims using MEG recording while participants perform a same-different matching task.

一项已公开发表的研宄揭示了读者对辅音与元音（CV）字母之间差异的敏感性。特别是，辅音与元音在书面词汇中的组织方式决定了其感知结构。这些研究结果的一个后果是，有必要修订现有的视觉词汇识别模型。在应对这一挑战之前，需要进一步验证两个假设，即首先，CV结构的影响发生在字母字符串处理的早期阶段，其次，CV模式决定了神经探测器编码正字法时的一级层次中的单位。该论文的目的是在参与者执行相同与不同匹配任务的同时，通过脑磁图（MEG）记录直接验证这两个论断。
