本研究通过两个实验考察词根词素频率和词频在句子语境中前缀词编码中的作用。两个替代词，这是等同的其他指标，但不同的词根词素频率或词频，嵌入在同一个句子框架。在实验1中，有一个显着的词根词素频率效应的注视时间，但只有一个边际词频效应。事后分析表明，词的长度影响这两种效果，词频效应占主导地位的较短的话和词根词素效应占主导地位的较长的话。在实验2中，单词长度也被操纵。词根频率对长词缀词有显著影响，对短词缀词有显著影响。最好的解释结果的双路线模型（与竞争的全字访问和组成的路线），其中增加单词长度抑制全字的过程中，相对于组成的路线。
Two experiments were performed to investigate the roles of root morpheme frequency and word frequency in the encoding of prefixed words in sentence context. Two alternative words, which were equated on other indices but differed with respect to either root morpheme frequency or word frequency, were embedded in the same sentence frame. In Experiment 1, there was a significant root morpheme frequency effect on gaze duration but only a marginal word frequency effect. Post hoc analyses indicated that word length influenced both effects, with word frequency effects predominating for shorter words and root morpheme effects predominating for longer words. In Experiment 2, word length was also manipulated. There was a significant root frequency effect for longer prefixed words and a significant word frequency effect for shorter prefixed words. The results were best explained by a dual-route model (with competing whole-word access and compositional routes), in which increasing word length inhibited the whole-word process, relative to the compositional route.
