In contrast, the predictive coding framework assumes that high proficient readers rely more on their reading experience to predict the upcoming context compared to low proficient readers (Hawelka et al., 2015). However, it is still unclear how skilled readers with different levels of reading proficiency rely on context information (e.g., predictability) for word processing during Chinese reading. In two experiments, the present study aimed to investigate individual differences in the use of predictability for word identification by using the eye-tracking technique. In Experiment 1, eye movements of fast and slow readers were recorded while they were reading sentences containing predictable or unpredictable target words, with the aim to investigate the differences in predictability effects between the two groups. Sixty pairs of predictable-unpredictable target words were selected, each of which was embedded into the same sentence frame. Fifteen fast and 15 slow readers, selected from a group of 66 participants based on their reading rates, participated in Experiment 1. In Experiment 2, parafoveal previews of the 60 predictable target words (identical word, visually similar pseudocharacter, unpredictable word or visually dissimilar pseudocharacter) were manipulated by using the boundary paradigm (Rayner, 1975) to explore how parafoveal preview influences processing of predictability information in the fast and slow readers. The eye movements of 20 fast and 20 slow readers, selected from a group of 80 participants on the basis of their reading rates, were recorded while they were reading sentences containing predictable target words with different previews in Experiment 2. The results showed that fast readers fixated shorter and less on the target words and were more likely to skip the target words than slow readers. In Experiment 1, although reliable predictability effects with shorter fixations for predictable than unpredictable words were found, it did not interact with reading groups. However, results in Experiment 2 showed robust parafoveal preview effects on the target word which interacted with reading groups. In particular, the two groups had the same first-pass fixation times (i.e., FFD, SFD, GD) at the target words under the identical previews, while slow readers made longer fixations than fast readers at the targets with unpredictable previews or unrelated previews. In addition, fast readers skipped target words at a similar probability under both the identical preview and unpredictable preview conditions, while slow readers were less likely to skip target words with unpredictable previews than identical previews. The current findings indicate that fast and slow readers rely on context to a similar degree during their foveal lexical processing whereas the two groups show different utilization of previews of the predictable word during their parafoveal processing. To be specific, compared to fast readers, slow readers are inefficient in activating the predictable word with a visually similar preview; moreover, slow readers are disturbed more by the unpredictable preview or the visually dissimilar preview for their lexical processing, which suggests that slow readers are less effective in suppressing unrelated or inappropriate information during reading. Such findings provide evidence for the lexical quality hypothesis (Perfetti, 2007) and are in support of the linguistic-pro?ciency hypothesis related to individual differences in the E-Z reader model (Reichle et al., 2013). 预测性中央凹加工副中央凹预视快速读者慢速读者中文阅读来自：张慢慢分类：心理学 >> 认知心理学引用： ChinaXiv:202206.00179 (或此版本 ChinaXiv:202206.00179V1 ) doi:10.12074/202206.00179 CSTR:32003.36.ChinaXiv.202206.00179.V1 推荐引用方式：张慢慢,胡惠兰,张志超,李鑫,汪强,白学军,臧传丽.(2022).预测性对快速读者和慢速读者词汇加工的影响.中国科学院科技论文预发布平台.[ChinaXiv:202206.00179] 版本历史 [V1] 2022-06-27 18:21:11 ChinaXiv:202206.00179V1 下载全文
