Dual-route models of reading postulate the existence of two separate mechanisms: The lexical route allows words to be recognized in their holistic form, and the sublexical route proceeds by converting the written sublexical entities of a word or a nonword into their corresponding phonological equivalents. Sublexical reading is assumed to require three stages of processing: graphemic parsing, graphophonemic conversion, and phoneme blending. This study provides evidence in favor of the existence of a graphemic parsing process which occurs prior to grapheme-phoneme conversion. A group of normal subjects read nonwords which contained multiletter graphemes significantly more slowly than graphemically simple nonwords. These results, best interpretable in the context of a recent dual-route model of reading, confirm previous data obtained in pathology which suggest the functional independence of this cognitive procedure.
词汇通道允许单词以整体形式被识别，而次词汇通道则通过将单词或非单词的书面次词汇实体转换为相应的语音等价物来进行。次词汇阅读被认为需要三个处理阶段：字素解析、字素-音素转换和音素合并。本研究提供了证据支持在字素-音素转换之前存在字素解析过程。一组正常受试者阅读包含多字母字素的非单词的速度明显慢于字素简单的非单词。这些结果，在最近的阅读双通道模型的背景下最易于解释，证实了先前在病理学中获得的数据，这些数据表明这种认知过程的功能独立性。
