Developmental Trajectories of Reading Development and Impairment from Ages 3 to 8 Years in Chinese Children.

BACKGROUND Early prediction of reading disabilities in Chinese is important for early remediation efforts. In this 6-year longitudinal study, we investigated the early cognitive predictors of reading skill in a statistically representative sample of Chinese children from Beijing. METHOD Two hundred sixty-one (261) native Chinese children were administered seven language-related skills over three years between the ages of 3 and 6 years. Performances on these skills were then examined in relation to subsequent word reading accuracy and fluency. Individual differences in developmental profiles across tasks were then estimated using growth mixture modeling. RESULTS Four developmental trajectories were classified - the typical (control), catch-up (with low initial cognitive performances but adequate subsequent reading), literacy-related-cognitive-delay (with difficulties in morphological awareness, phonological awareness, and speeded naming and subsequent word recognition), and language-delay (relatively low across all tasks) groups. CONCLUSION Findings suggest that the combination of phonological awareness, rapid naming and morphological awareness are essential in the early prediction of later reading difficulties in Chinese children.

Eye-voice span during rapid automatized naming of digits and dice in Chinese normal and dyslexic children.

We measured Chinese dyslexic and control childrens eye movements during rapid automatized naming (RAN) with alphanumeric (digits) and symbolic (dice surfaces) stimuli. Both types of stimuli required identical oral responses, controlling for effects associated with speech production. Results showed that naming dice was much slower than naming digits for both groups, but group differences in eye-movement measures and in the eye-voice span (i.e. the distance between the currently fixated item and the voiced item) were generally larger in digit-RAN than in dice-RAN. In addition, dyslexics were less efficient in parafoveal processing in these RAN tasks. Since the two RAN tasks required the same phonological output and on the assumption that naming dice is less practiced than naming digits in general, the results suggest that the translation of alphanumeric visual symbols into phonological codes is less efficient in dyslexic children. The dissociation of the print-to-sound conversion and phonological representation suggests that the degree of automaticity in translation from visual symbols to phonological codes in addition to phonological processing per se is also critical to understanding dyslexia.

Poor Readers of Chinese and English: Overlap, Stability, and Longitudinal Correlates

We tested the overlap in the bottom 25% of scorers (termed “poor readers”) in word reading in Chinese and English, respectively, among statistically representative groups of 8-year-olds from Hong Kong and Beijing in order to determine the chances of being a poor reader in English given that one was already a poor reader in Chinese. The overlap in the status of poor reader was 32% in Hong Kong and 40% in Beijing. For the Beijing sample only, we also examined longitudinal correlates of children who were poor readers of Chinese only, of English only, or poor readers in both, relative to controls at age 8. Poor readers of either Chinese or English scored the same on phonological awareness relative to controls, and poor readers of Chinese were lower than those who were poor readers of English on morphological awareness. Those children who were poor in both scored significantly lower in phonological awareness and morphological awareness, as well as slower in rapid automatized naming, over time, relative to the other groups. Results suggest that it is possible to be poor in reading of either Chinese or English or both and that the cognitive correlates of such difficulties may differ by orthography.

Parafoveal Load of Word N+1 Modulates Preprocessing Effectiveness of Word N+2 in Chinese Reading.

Preview benefits (PBs) from two words to the right of the fixated one (i.e., word N + 2) and associated parafoveal-on-foveal effects are critical for proposals of distributed lexical processing during reading. This experiment examined parafoveal processing during reading of Chinese sentences, using a boundary manipulation of N + 2-word preview with low- and high-frequency words N + 1. The main findings were (a) an identity PB for word N + 2 that was (b) primarily observed when word N + 1 was of high frequency (i.e., an interaction between frequency of word N + 1 and PB for word N + 2), and (c) a parafoveal-on-foveal frequency effect of word N + 1 for fixation durations on word N. We discuss implications for theories of serial attention shifts and parallel distributed processing of words during reading.

Chinese Deaf Readers Have Early Access to Parafoveal Semantics.

In the present study, we manipulated different types of information available in the parafovea during the reading of Chinese sentences and examined how deaf readers make use of the parafoveal information. Results clearly indicate that although the reading-level matched hearing readers make greater use of orthographic information in the parafovea, parafoveal semantic information is obtained earlier among the deaf readers. In addition, a phonological preview benefit effect was found for the better deaf readers (relative to less-skilled deaf readers), although we also provide an alternative explanation for this effect. Providing evidence that Chinese deaf readers have higher efficiency when processing parafoveal semantics, the study indicates flexibility across individuals in the mechanisms underlying word recognition adapting to the inputs available in the linguistic environment.

Saccade-target selection of dyslexic children when reading Chinese.

This study investigates the eye movements of dyslexic children and their age-matched controls when reading Chinese. Dyslexic children exhibited more and longer fixations than age-matched control children, and an increase of word length resulted in a greater increase in the number of fixations and gaze durations for the dyslexic than for the control readers. The report focuses on the finding that there was a significant difference between the two groups in the fixation landing position as a function of word length in single-fixation cases, while there was no such difference in the initial fixation of multi-fixation cases. We also found that both groups had longer incoming saccade amplitudes while the launch sites were closer to the word in single fixation cases than in multi-fixation cases. Our results suggest that dyslexic childrens inefficient lexical processing, in combination with the absence of orthographic word boundaries in Chinese, leads them to select saccade targets at the beginning of words conservatively. These findings provide further evidence for parafoveal word segmentation during reading of Chinese sentences.

Rapid Automatized Naming and Its Unique Contribution to Reading: Evidence from Chinese Dyslexia

Rapid automatized naming (RAN) is suggested to be a significant predictor of reading. However, how it is related to reading and whether it contributes uniquely to reading with phonological awareness statistically controlled is unclear. In this chapter, we reported a study of 45 fourth and fifth grade Chinese children with dyslexia and 45 age-matched controls. They were administrated processing speed tasks, auditory temporal processing, RAN, phonological awareness, Chinese character recognition, and timed word list reading. Results showed that Chinese dyslexic children performed poorer than typical developing children in all tasks. And principal component analyses revealed that RAN loaded in both phonological processing and processing speed component. RAN uniquely predicted Chinese timed and untimed word reading, while phonological awareness predicted only untimed Chinese word reading. The underlying mechanism and the role of RAN in Chinese were discussed.

Parafoveal processing in silent and oral reading: Reading mode influences the relative weighting of phonological and semantic information in Chinese.

We examined how reading mode (i.e., silent vs. oral reading) influences parafoveal semantic and phonological processing during the reading of Chinese sentences, using the gaze-contingent boundary paradigm. In silent reading, we found in 2 experiments that reading times on target words were shortened with semantic previews in early and late processing, whereas phonological preview effects mainly occurred in gaze duration or second-pass reading. In contrast, results showed that phonological preview information is obtained early on in oral reading. Strikingly, in oral reading, we observed a semantic preview cost on the target word in Experiment 1 and a decrease in the effect size of preview benefit from first- to second-pass measures in Experiment 2, which we hypothesize to result from increased preview duration. Taken together, our results indicate that parafoveal semantic information can be obtained irrespective of reading mode, whereas readers more efficiently process parafoveal phonological information in oral reading. We discuss implications for notions of information processing priority and saccade generation during silent and oral reading. (PsycINFO Database Record

Perceptual Span in Oral Reading: The Case of Chinese

ABSTRACT The present study explores the perceptual span, that is, the physical extent of the area from which useful visual information is obtained during a single fixation, during oral reading of Chinese sentences. Characters outside a window of legible text were replaced by visually similar characters. Results show that the influence of window size on the perceptual span was consistent across different fixation and oculomotor measures. To maintain normal reading behavior when reading aloud, it was necessary to have information provided from three characters to the right of the fixation. Together with findings from previous research, our findings suggest that the physical size of the perceptual span is smaller when reading aloud than in silent reading. This is in agreement with previous studies in English, suggesting that the mechanisms causing the reduced span in oral reading have a common base that generalizes across languages and writing systems.

Parafoveal activation of sign translation previews among deaf readers during the reading of Chinese sentences

In the present study, we manipulated the different types of information available in the parafovea during the reading of Chinese sentences and examined whether deaf readers could activate sign translations of Chinese words during reading. The main finding was that, as compared to unrelated previews, the deaf readers had longer fixation durations on the target words when sign-phonologically related preview words were presented; this preview cost effect due to sign-phonological relatedness was absent for reading-level-matched hearing individuals. These results indicate that Chinese deaf readers activate sign language translations of parafoveal words during reading. We discuss the implications for notions of parafoveal processing in reading.
