摘　　要：目的探讨词频和语境预测性在老年人阅读中的作用。方法使用眼动追踪技术,采用2(年龄:老年人、青年人)×2(目标词词频:高、低)×2(语境预测性:高、低)的多因素混合实验设计,分析老年人阅读目标词的眼动特征。结果与青年人相比,老年人在阅读时需要更多的阅读时间和注视次数,有更多地向右眼跳次数,更容易发生跳读。结论词频和语境预测性同样会对老年人阅读产生影响,老年人的词频效应更明显。Objective To explore the effect of word frequency and word predictability in reading of elderly people and the eye movement characteristics of older adults.Methods The participants were sixteen older adults and sixteen young adults with normal or corrected-to-normal vision.The eye movement technique was used in the present research.It was the mixed experimental design which was designed as 2（age： older adults and young adults）×2（frequency： high frequency and low frequency）×2（predictability： predictable context and unpredictable context）.Results Older adults read more slowly,made more fixations and forward saccade counts than younger readers,They were more likely to skip a target word than younger readers.Conclusions Older readers are influenced by word frequency and word predictability.The frequency effect is larger for the older adults than for the younger adults.
