Abstract： A debated issue in eye movement reading research concerns the extent to which readers preprocess words in the parafovea. There have been convergent findings that readers can extract visual and lexical (e.g., orthographic, phological) information from parafoveal words during reading. However, there is some controversy regarding whether readers can extract higher linguistic level (e.g., semantic and syntactic) information from the parafovea. We reviewed current findings in relation to parafoveal preview benefits during reading of alphabetic languages like English and non-alphabetic language like Chinese, mainly focusing on the processing of semantic and syntactic information of upcoming words in the parafovea, and how the current eye movement control models such as E-Z reader model and SWIFT model explain these findings. Finally, we discussed the implications of semantic and syntactic preview benefits for these models and considered future research directions in this field of eye movement control during reading.

Abstract： The ability to pre-process information from the parafovea, a hallmark component of skilled reading ( Blythe & Joseph, 2011), refers to the fact that readers visually and linguistically analyse upcoming words prior to their direct fixation. Previous findings regarding depth of pre-processing effects that are based on alphabetic language reading are mixed. One very important reason is that there is considerable variability in the length of target words in those studies conducted on alphabetic reading scripts. By contrast, it is possible to conduct such studies in Chinese to allow for parafoveal processing of text to be operationalized over characters without length variability. Chinese is a language with characteristics that are optimal for investigating parafoveal processing. The present project will take advantage of Chinese text characteristics to examine three aspects of parafoveal processing by using the eye tracking technique: (1) the first study aims at exploring how parafoveal load affects the spatial extent of pre-processing; (2) the second study attempts to examine whether and how foveal load influences the spatial extent and depth of pre-processing; on the basis of the first two studies, (3) the third study will investigate how reading skill modulates the spatial and depth effects of parafoveal processing, and also how reading efficiency interacts with spatial extent and depth of pre-processing. The findings of the current project will seek to illuminate currently controversial issues on parafoveal processing, and will be beneficial for examining and extending the current reading models of eye movement control (e.g., E-Z reader model, SWIFT model).

Abstract： A controversial issue in eye movement research investigating reading concerns whether high-level information (e.g., syntactic category information) of parafoveal words can be obtained prior to fixation. Researchers have demonstrated that readers could stably extract syntactic category information from the parafoveal words during English reading, and such findings are in favor of parallel graded processing model (e.g., SWIFT model). Unlike English, Chinese are not rich in inflectional or derivational indicators to specify words’ syntactic properties. For example, there is no inflection with the verb 包装 (pack) no matter whether this action is going to happen or has already happened, nor whether this word is used as a verb or a noun. Therefore, parafoveal syntactic cues in Chinese may be limited relative to English, meaning that the extraction and use of such information when making syntactic commitments may be delayed. The present study was to explore whether parafoveal word class information could be extracted during Chinese reading. Using the boundary paradigm (Rayner, 1975), we manipulated the syntactic category (word class) of preview words to form three conditions: identical preview, preview with the same word class as the target word, preview with the different word class as the target word. 120 college students participated in the experiment. Eye movements were recorded using an Eyelink 1000 eye-tracker, and the recorded results (reading time and fixation probability) are the dependent variables. Participants were asked to read 45 sentences and answered a multiple-choice comprehension question if any (about 30%). Although participants were only exposed to each target word once, all sentences appeared in all preview conditions across three counterbalanced lists. The results showed that readers spent similar duration when they fixed the target word regardless of whether the word class of the preview word in the parafovea was same as the target word or not, and there was no significant difference in fixation probability between them. Supplementary Bayesian analysis supported the null hypothesis. Moreover, all fixation durations were significantly shorter for the identical condition than for the other two previews, skipping rate was higher for identical condition, and regression probabilities were lower for identical condition. The findings in the present study suggest that it is difficult for Chinese readers to extract high-level syntactic category information from parafoveal words. Our results provide support for the sequential attention shift model (e.g., E-Z reader model), which in favor of that high-level information processing occurs in the integration stage (I). The results provide evidence for improving computational models of eye movements about how to process lexical high-level information during reading.

Abstract： According to the lexical quality hypothesis, high proficient (fast) readers have well-specified lexical representations which enable automatic word identification and less context decoding, while low proficient (slow) readers rely on context for word identification during reading due to their imprecise lexical quality. 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. 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 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 and are in support of the linguistic-pro?ciency hypothesis related to individual differences in the E-Z reader model.

Abstract： According to the lexical quality hypothesis, high proficient (fast) readers have well-specified lexical representations which enable automatic word identification and less context decoding (Andrews, 2015; Perfetti, 2007), while low proficient (slow) readers rely on context for word identification during reading due to their imprecise lexical quality. 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.

Abstract： Parafoveal pre-processing contributes to highly efficient reading for skilled readers (Ashby et al., 2012; Rayner, 2009). Research has demonstrated that high-skilled or fast readers extract more parafoveal information from a wider parafoveal region more efficiently compared to less-skilled or slow readers (e.g., Ashby et al., 2012; Chace et al., 2005; Rayner et al., 2010; Veldre & Andrews, 2015a). It is argued that individual differences in parafoveal preview are due to high-skilled or fast readers focusing less of their attention on foveal word processing than less-skilled or slow readers (Rayner, 1986; Veldre & Andrews, 2014). In other words, foveal processing difficulty might modulate an individual’s amount of parafoveal preview (Foveal Load Hypothesis, Henderson & Ferreira, 1990). However, few studies have provided evidence in support of this claim. Therefore, the present study aimed to explore whether and how foveal lexical processing load modulates parafoveal preview of readers with different reading speeds (a commonly used measurement of reading skill or reading proficiency). By using a three-minute reading comprehension task, 28 groups of fast and slow readers were selected from 300 participants (234 were valid) according to their reading speed in the current study. Participants were then asked to read sentences while their eye movements were recorded using an Eyelink 1000 eyetracker. Each experimental sentence contained a pre-target word that varied in lexical frequency to manipulate foveal processing load (low load: high frequency; high load: low frequency), and a target word manipulated for preview (identical or pseudo-character) within the boundary paradigm (Rayner 1975). Global analyses showed that, although fast readers had similar accuracy of reading comprehension to slow readers, they had shorter reading times, longer forward saccades, made less fixations and regressions, and had higher reading speeds compared to slow readers, indicating that our selection of fast and slow readers was highly effective. The pre-target word analyses showed that there was a main effect of word frequency on first-pass reading times, indicating an effective manipulation of foveal load. Additionally, there was an interactive effect between reading group and word frequency for first fixation and single fixation durations, showing that fast readers fixated high frequency pre-target words for less time than low frequency pre-target words, while slow readers made similar duration fixations on the high and low frequency pre-target words. However, the target word analyses did not show any three-way or two-way interactions for the first-pass reading times as well as for skipping probability. To be specific, the first-pass reading times were shorter at the target word with identical previews in relation to pseudocharacter previews (i.e. preview benefit effects); importantly, similar size effects occurred for both fast readers and slow readers. The findings in the present study suggest that lexical information from the currently fixated word can be extracted and can be used quickly for fast readers, while such information is used later for slow readers. This, however, does not result in more (or less) preview benefit for fast readers in relation to slow readers. In conclusion, foveal lexical processing does not modulate preview benefit for fast and slow readers, and the present results provide no support for the Foveal Load Hypothesis. Our findings of foveal load effects on parafoveal preview for fast and slow readers cannot be readily explained by current computational models (e.g., E-Z Reader model and SWIFT model).
