Abstract： The irrelevant speech effect (ISE) refers to the interferential performance in visual cognitive task when the background speech is presented at the same time. In the present paper, we first introduced two main theoretical accounts of the mechanism underlying ISE in reading: interference-by-content hypothesis and interference-by-process hypothesis. Then extant studies of ISE in reading were summarized and discussed over these two opposite hypotheses. Lastly, we proposed several issues which are worth to be focused in the future studies: a) what and how the relevant factors impact on ISE; b) the cognitive stages concerning ISE during reading; c) the application of new technologies including brain imaging technology and eye-tracking technology into studies of ISE in reading.

Abstract： Compared with hearing readers, orthographic information and phonological information may play different roles in the word recognition process for hearing-impaired readers. As a communication mode for hearing-impaired readers, sign language may also affect their word recognition process. A large number of studies have examined the activation of orthographic representation, phonological representation, and sign language representation during visual word recognition in hearing-impaired readers. Previous studies have found that hearing-impaired readers could activate stable orthographic representations, but there were inconsistent results in the activation of phonological representations, whereas studies on hearing-impaired readers who primarily use sign language have found that they can activate stable sign language representations. Hearing-impaired readers grow up in a complex language environment, which leads to great individual differences in language experience and reading ability. However, previous works have not clearly identified the effect of language experience and reading ability on the cognitive mechanism of reading in hearing-impaired readers. Continuous attention to this problem will help to provide a reference to guide reading instruction for hearing-impaired readers. This study conducted two semantically related decision tasks to investigate the activation of orthographic, phonological, and sign language representations during Chinese visual word recognition in hearing-impaired college students. Orthographic and phonological representations play an important role in word recognition for hearing readers, but sign language representations are a phenomenon unique to deaf readers. In the current study we investigated the activation of orthographic and phonological representation in Experiment 1 and the activation of sign language representation in Experiment2. To investigate the effects of individual differences, according to their language experience and reading fluency, hearing-impaired college students were divided into deaf college students with oral language experience and higher reading ability (Skilled Oral Deaf, SOD), deaf college students with sign language experience but higher reading ability (Skilled Sign Deaf, SSD), and deaf college students with sign language experience and lower reading ability (Less-Skilled Sign Deaf, LSSD). The results of Experiment 1 showed that (a) hearing students showed a stable orthographic interference effect, whereas the phonological interference effect was weak. (b) The SOD group and the SSD group showed similar performance. Both showed a stable orthographic interference effect but did not show a significant phonological interference effect. (c) The SSD group and the LSSD group showed similar performance. Both groups showed a stable orthographic interference effect but did not show a phonological interference effect. Experiment 2 found that (a) hearing students did not show a sign language interference effect. (b) The SOD group and the SSD group differed in performance. The SSD group exhibited a sign language interference effect, whereas this effect was absent in the SOD group. (c) The SSD group performed similarly to the LSSD group. Both groups showed a stable sign language interference effect. Taken together, the following conclusions were drawn from the two studies: (a) after controlling for reading ability, language experience affected Chinese lexical recognition in deaf college students; lexical representation of oral deaf college students was similar to that of hearing readers., orthographic representations were mainly activated; and the activation of phonological and sign language representations was weak. Deaf college students who used sign language developed a unique cognitive mechanism, and they activated stable orthographic and sign language representations during visual word recognition. (b) After controlling for language experience, reading ability did not affect lexical representation during Chinese word recognition in hearing-impaired college students. (c) Based on the results of this study, combined with the representation and processing models of Chinese word recognition, we attempted to construct a cognitive model of Chinese word recognition for hearing-impaired college readers.

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).

Abstract： 研究探讨汉语读者选择眼跳目标时, 中央凹注视词的加工负荷是否影响副中央凹获取信息量, 进而调节随后的眼跳长度。采用眼动追踪技术, 操纵了中央凹注视词的词频(高频、低频)和副中央凹词的笔画数(多笔画、少笔画)。结果发现：从中央凹词到副中央凹少笔画词的眼跳长度显著地长于到多笔画词的, 且这种笔画数效应并不受中央凹加工负荷的调节; 从高频中央凹词到副中央凹词的眼跳长度显著地长于低频词的。在本实验条件下结果提示：中央凹加工负荷在眼跳目标选择中的作用不是通过调节副中央凹获取信息量的多少来实现的。

Abstract： Visual information is essential to deaf people given their early auditory deprivation. Some researchers have proposed a perspective in which the distribution of deaf visual attention resource shifted from the central to the extrafoveal visual field. This study explores how this unique visual processing ability may influence reading in deaf people and proposes ‘the effect of parafoveal visual attention enhancement in deaf reading.’ We hypothesise that visual attention resources are reorganised due to the absence of auditory input for deaf people. This reorganisation increased distribution toward the extrafoveal field, but decreased it in the foveal field, resulting in poor reading efficiency. A total of 29 severely to profoundly deaf students (DS) from a deaf school in Tianjin participated in the present study. Their hearing loss is ≥ 90 dB in the better ear. Participants are either born deaf or became deaf before three years old, and they use Chinese Sign Language (CSL) as their main communication mode. None of them received a cochlear implant. The age control group (AC) has 29 hearing middle school students, which indicated no significant difference in chronological age with DS. In addition, 29 hearing primary students comprised the reading-level control group (RC). The DS and RC were examined through a series of reading tests, including orthographic judgment task, reading fluency and reading comprehension, to match their reading levels. All participants read Chinese sentences for comprehension as their eye movements were tracked. A total of 48 pairs of target words (48 high frequency and 48 low frequency words) were embedded in two different sentence frames. All sentences consisted of seven or eight double-character words. These sentences were either presented normally or in a disappearing text paradigm that, as each word (n) was fixated, the word (n) or the next word (n + 1) remained visible only for a short period (40 ms) before disappearing. The paradigm was utilised to manipulate the display duration for the parafoveal word n + 1 (Experiment 1) or the foveal word N (Experiment 2) respectively, to compare the efficiency (speed) of encoding visual text information in sentence reading. In Experiment 1, when word n + 1 was presented briefly (40 ms), the overall sentence reading times were prolonged only for reading-level control group, but no difference was observed between deaf students and age control group. The effect of word frequency on target words was normal for all three groups. By contrast, in Experiment 2, during which word n was presented briefly (40 ms), the overall sentence reading times were prolonged only for deaf students. For gaze duration, the effect of word frequency for target words disappeared for deaf students. Therefore, deaf students showed higher efficiency of encoding parafoveal text information than their reading-level controls in Experiment 1 and were equal to their age controls. However, in Experiment 2, deaf students showed lower efficiency in encoding foveal text information than those in the hearing controls. In conclusion, the present study confirmed that deaf readers have enhanced parafoveal processing of linguistic information, but their foveal processing was hampered as a consequence. Thus, parafoveal visual attention was enhanced in deaf reading, which may be one of reasons for reading difficulty. Further research is necessary to explore this issue.
