Abstract：
Efficient word recognition is important to facilitate reading comprehension. Two important factors influence word recognition-word frequency (WF) and contextual diversity (CD)-but studies have not reached consistent conclusions on their role. Based on previous studies, the present study strictly controlled the anticipation of sentence context on target words. In the context of the semantic incongruence of Chinese sentences-that is, when the context is equivalent and low in anticipation of the target noun-CD effects were found on late processing indicators of the eye movement data of parafoveal words, and the CD feature of parafoveal words led to a significant parafoveal-on-foveal effect. However, none of these results were found in the semantically reasonable (semantic congruence) context. The results suggested that high CD words are better at adapting to unexposed or learned contexts, which was not the case for high WF words.
摘要：
有效的单词识别对于促进阅读理解很重要。影响单词识别的两个重要因素-单词频率（WF）和上下文多样性（CD）-但研究尚未就其作用得出一致的结论。根据以前的研究，本研究严格控制句子上下文对目标词的预期。在汉语句子语义不一致的背景下，当上下文相等且对目标名词的预期较低时，在后凹词的眼动数据的后期处理指标上发现CD效应，半凹词的CD特征导致了中央凹对半凹的明显影响。然而,这些结果均未在语义合理（语义一致性）的上下文中发现。结果表明，高CD单词更好地适应未暴露或学习的上下文，高WF单词的情况并非如此。
