The Global and Local Patterns of Reading-Related Cognitive and Ecological Variables in Chinese First-Grade Children: A Cross-Sectional Network Analysis.

In the current study, we tested a network model of reading difficulty by using state-of-the-art psychological network analysis. Four hundred and fifty-three Chinese first-grade children (about 38% female, mean age = 7.00, SD = 0.41) were divided into good (n = 154), competent (n = 147), and struggling readers (n = 152) based on their scores of Chinese character reading. The Extended Bayesian Information Criterion graphical lasso (EBICglasso) method was applied to estimate cross-sectional networks for the three groups. Each network included four cognitive nodes (homophone awareness, morphological structure awareness, phonological awareness, and vocabulary) and two ecological nodes (family socioeconomic status and the number of books at home). Chronological age and nonverbal intelligence were also included in the estimated networks. The global (i.e., global structure and global connectivity) and local patterns (i.e., the most important edges and nodes) in each network were reported. The network comparison results showed that global connectivity was significantly lower among struggling readers than for good readers, implying that a holistic impairment of bidirectional connections among multiple variables relates to the difficulty in learning to read. The theoretical and empirical implications and the significance of applying the network approach to reading research are discussed.

Spatiotemporal Neural Network for Sublexical Information Processing: An Intracranial SEEG Study.

Words offer a unique opportunity to separate the processing mechanisms of object subcomponents from those of the whole object, because the phonological or semantic information provided by the word subcomponents (i.e., sublexical information) can conflict with that provided by the whole word (i.e., lexical information). Previous studies have revealed some of the specific brain regions and temporal information involved in sublexical information processing. However, a comprehensive spatiotemporal neural network for sublexical processing remains to be fully elucidated due to the low temporal or spatial resolutions of previous neuroimaging studies. In this study, we recorded stereoelectroencephalography (SEEG) signals with high spatial and temporal resolutions from a large sample of 39 epilepsy patients (both sexes) during a Chinese character oral reading task. We explored the activated brain regions and their connectivity related to three sublexical effects: phonological regularity (whether the whole character's pronunciation aligns with its phonetic radical), phonological consistency (whether characters with the same phonetic radical share the same pronunciation), and semantic transparency (whether the whole character's meaning aligns with its semantic radical). The results revealed that sublexical effects existed in the inferior frontal gyrus, precentral and postcentral gyri, temporal lobe, and middle occipital gyrus. Additionally, connectivity from the middle occipital gyrus to the postcentral gyrus and from postcentral gyrus to the fusiform gyrus was associated with the sublexical effects. These findings provide valuable insights into the spatiotemporal dynamics of sublexical processing and object recognition in the brain.Significance statement Elucidating the intricate neural mechanisms underlying sublexical processing is crucial for understanding the intricacies of language comprehension and object recognition in the human brain. This study employed intracranial stereoelectroencephalography (SEEG) recordings to investigate the spatiotemporal dynamics of sublexical processing during a Chinese character reading task. We constructed a neural network for sublexical processing and depicted its temporal sequence in different brain regions. Furthermore, we identified the information flow within this network and observed its variation with the reading of characters containing different sublexical information. These findings not only advance our understanding of the cerebral mechanisms governing sublexical processing but also offer insights into the broader framework of object recognition processes.

Young Chinese Language Learners’ L2 Motivational Self System and Learning Achievement in Chinese Literacy Acquisition

ABSTRACT This study investigated the impact of young Chinese second language learners’ motivation on their Chinese literacy acquisition. Based on the L2 Motivational Self System (L2MSS), 188 Grade 5 ethnic minority students in Hong Kong were assessed. They completed an L2MSS questionnaire, a Chinese oral vocabulary test, and Chinese literacy measures, which covered Chinese character reading, spelling, reading comprehension, and sentence writing. Structural equation modelling results showed that the L2MSS tripartite predictors—ideal L2 self, ought-to L2 self, and learning experience—predicted the students’ intended learning effort and literacy achievement, controlling for oral vocabulary. The ought-to self had the strongest total effect on effort and achievement, while the ideal self had a substantial effect on the learning experience and indirectly contributed to effort. This study argues that young learners’ perceived social expectation significantly influenced their motivation to learn to read and write Chinese. Their identification as fluent Chinese readers and writers generated positive learning experiences that were conducive to literacy learning.

Visual cortex anodal transcranial direct current stimulation does not alter reading performance for Chinese presented character-by-character to normal peripheral vision in older adults.

Visual cortex anodal transcranial direct current stimulation (a-tDCS) has been shown to reduce crowding in normal peripheral vision and may improve the reading of English words in patients with macular degeneration. Given the different visual requirements of reading English words and Chinese characters, the effect of a-tDCS on peripheral reading performance in English might differ from Chinese. This study recruited 20 participants (59-73 years of age) with normal vision and tested the hypothesis that a-tDCS would improve the reading of Chinese characters presented at 10° eccentricity compared with sham stimulation. Chinese sentences of different print sizes and exposure durations were presented one character at a time, 10° below or to the left of fixation. The individual critical print size (CPS) - the smallest print size eliciting the maximum reading speed (MRS) - was determined. Reading accuracies for characters presented 0.2 logMAR smaller than the individually fitted CPS were measured at four time points: before, during, 5 min after, and 30 min after receiving active or sham visual cortex a-tDCS. Participants completed both the active and sham sessions in a random order following a double-blind, within-subject design. No effect of active a-tDCS on reading accuracy was observed, implying that a single session of a-tDCS did not improve Chinese character reading in normal peripheral vision. This may suggest that a-tDCS does not significantly reduce the crowding elicited within a single Chinese character. However, the effect of a-tDCS on between-character crowding is yet to be determined.

The role of body–object interaction in children’s concept processing: insights from two Chinese communities

A rating of body–object interactions (BOIs) reflects the ease with which a human body can interact physically with a word’s referent. Studies with adults have demonstrated a facilitating BOI effect in language tasks, with faster and more accurate responses for high BOI words (e.g., cup) than low BOI words (e.g., coal). A few studies have explored the BOI effect in children. However, these studies have all adopted adult-rated BOIs, which may differ from children’s. Using child-rated BOIs, the present study investigated the BOI effect in Chinese children and its relationship with age, as well as whether there was a community difference in the BOI effect. Children (aged 7–8) from Mainland China (N = 100) and Hong Kong SAR (HK; N = 90) completed a lexical decision task used to measure the BOI effect. The children were asked to judge whether each item was a real Chinese word; each real word was assigned a child-rated BOI score. After controlling nonverbal intelligence, gender, working memory, and Chinese character reading, a significant BOI effect was observed at the response accuracy and speed levels. The accuracy and latency analyses illustrated a community difference; the BOI effect was smaller in the HK children. This study suggests that BOI measures may be sensitive to the ecological differences between tested communities. The findings support the need for further investigations into the BOI effect across Chinese communities, particularly those in Mainland China.

A genome-wide association study of Chinese and English language phenotypes in Hong Kong Chinese children

Dyslexia and developmental language disorders are important learning difficulties. However, their genetic basis remains poorly understood, and most genetic studies were performed on Europeans. There is a lack of genome-wide association studies (GWAS) on literacy phenotypes of Chinese as a native language and English as a second language (ESL) in a Chinese population. In this study, we conducted GWAS on 34 reading/language-related phenotypes in Hong Kong Chinese bilingual children (including both twins and singletons; total N = 1046). We performed association tests at the single-variant, gene, and pathway levels. In addition, we tested genetic overlap of these phenotypes with other neuropsychiatric disorders, as well as cognitive performance (CP) and educational attainment (EA) using polygenic risk score (PRS) analysis. Totally 5 independent loci (LD-clumped at r2 = 0.01; MAF > 0.05) reached genome-wide significance (p < 5e-08; filtered by imputation quality metric Rsq>0.3 and having at least 2 correlated SNPs (r2 > 0.5) with p < 1e-3). The loci were associated with a range of language/literacy traits such as Chinese vocabulary, character and word reading, and rapid digit naming, as well as English lexical decision. Several SNPs from these loci mapped to genes that were reported to be associated with EA and other neuropsychiatric phenotypes, such as MANEA and PLXNC1. In PRS analysis, EA and CP showed the most consistent and significant polygenic overlap with a variety of language traits, especially English literacy skills. To summarize, this study revealed the genetic basis of Chinese and English abilities in a group of Chinese bilingual children. Further studies are warranted to replicate the findings.

Phonological awareness and RAN contribute to Chinese reading and arithmetic for different reasons.

The present study investigated how phonological awareness and rapid automatized naming (hereafter, RAN), simultaneously contributed to Chinese reading and arithmetic fluency. Specifically, we proposed a new hypothesized mechanism that processing speed would mediate the relations of RAN with Chinese reading and arithmetic fluency. One hundred and forty-five Chinese children at the fifth grade were administered with a battery of measures, including three phonological processing measures, character reading, and whole number computation, as well as nonverbal IQ, and vocabulary knowledge. Path analyses revealed that phonological awareness and RAN were uniquely related to character reading and arithmetic fluency, while phonological memory was not significantly correlated to either character reading or arithmetic fluency, after controlling for age, nonverbal IQ, and vocabulary knowledge. Further analysis indicated that processing speed demonstrated a mediating effect on the importance of RAN in character reading, rather than in arithmetic fluency. Results underscore the potential importance of phonological awareness and RAN in character reading and arithmetic fluency, and the mediating role of processing speed in RAN to promote Chinese character reading fluency.

The cognitive-linguistic profiles and academic performances of Chinese children with dyslexia across cultures: Beijing, Hong Kong, and Taipei.

This study examined the cognitive-linguistic and literacy-related correlates of dyslexia in three Chinese cities and the English word reading and mathematics performances of Chinese children with dyslexia. Chinese children with/without dyslexia were measured with an equivalent test battery of literacy and mathematics in Beijing, Hong Kong, and Taipei. Univariate analysis results suggested that phonological sensitivity distinguished those with and without dyslexia across all three cities in group comparisons. In Taipei and Hong Kong, morphological awareness, delayed copying, and spelling also distinguished the groups. Logistic regression analyses demonstrated that Chinese character reading, as directly compared to Chinese word reading, also distinguished the groups particularly well. In addition, in Beijing and Hong Kong, children with dyslexia performed significantly less well in English word reading than those without dyslexia. In Hong Kong and Taipei, children with dyslexia also had difficulties in mathematics performance. Findings highlight the fundamental importance of some cognitive-linguistic skills for explaining Chinese dyslexia across cultures, the utility of recognizing the individual Chinese character as a foundational unit of analysis in Chinese across cultures, and the generalizability of the comorbidity of both English as a second language (L2) and mathematics with dyslexia in Chinese children in both Beijing and Hong Kong.

The Effectiveness of Diverse Designs of Chinese Stem-Deriving Instruction for Chinese Children With Dyslexia

One of the most well-known instructional methods used to enhance Chinese character reading (CCR) is Chinese stem-deriving instruction (CSDI). In this method, CCR is taught via a group of characters (e.g., 清, 情, and 靚) that share the same stem (e.g., 青). However, the effectiveness of CSDI on the CCR of Chinese children with dyslexia remains inconsistent, and the reason may be the diverse designs of this method across studies. Thus, this study aimed to use a quasiexperiment-design study to compare the effects of various forms of CSDI based on the (in)consistency of the extending characters’ sounds, their appearances, and their amount (i.e., how many of them). In total, 122 Chinese third to sixth graders with dyslexia were recruited from primary schools, and they were randomly assigned to one of three groups: (a) visuospatially controlled CSDI ( n = 37; all taught characters shared the same pronunciation), (b) verbally controlled CSDI ( n = 45; all taught characters shared the same structure), and (c) noncontrolled CSDI ( n = 40; all taught characters selected only on the basis of their frequencies). They were tested by CCR and dictation before and after the instruction. We found that CCR was significantly improved in all three CSDI groups, whereas only the verbally controlled CSDI group showed significant improvements in dictation. Furthermore, verbally and visuospatially controlled CSDI earned the greatest benefits in decreasing the visual errors and phonetic errors in CCR and decreasing the radical errors and homophone errors in dictation. Our findings shed light on the effectiveness of CSDI in terms of diverse designs, and frontline practitioners should take our findings into consideration when using CSDI.

The impact of Home Literacy Environment on Chinese children's character recognition, vocabulary knowledge, and reading comprehension: A developmental cascade model

The impact of Home Literacy Environment on Chinese children's character recognition, vocabulary knowledge, and reading comprehension: A developmental cascade model

A Preliminary Study of Brain Functional Magnetic Resonance Imaging in Text Reading and Comprehension.

Few studies have focused on the changes in human brain function activities caused by reading Chinese characters with different intelligibility and whether it can reflect the understanding and cognitive ability of the human brain. Task-fMRI based on Chinese character reading tasks with different intelligibility was used to explore activated brain regions and their cognitive changes. Volunteers were randomly recruited using advertisements. Forty volunteers were recruited based on strict inclusion and exclusion criteria, and 40 volunteers were recruited. Brain function data of 40 healthy right-handed volunteers in fuzzy/clear Chinese reading tasks were collected using a Siemens Skyra 3.0T magnetic resonance scanner. Data were preprocessed and statistically analyzed using the statistical software SPM12.0 to observe the activation of the cortex and analyze its characteristics and possible changes in cognitive function. Task-fMRI analysis: (1) The main brain regions activated in fuzzy/clear reading tasks were located in the occipital visual cortex (P < 0.001); (2) a paired sample t-test suggested that there was a significant difference in BOLD signals in the brain regions activated by fuzzy/clear reading tasks (P < 0.001, equiv Z = 4.25). Compared with the fuzzy reading task, the brain regions more strongly activated in the clear reading task were mainly located in the right superior frontal gyrus and the bilateral temporal lobe. Compared with the clear reading task, the brain region that was more strongly activated in the fuzzy reading task was mainly located in the right fusiform gyrus. Clear Chinese character information mainly activates the dorsal stream of the visual-spatial network. This reflects the information transmission of the brain after understanding the text content and is responsible for guiding and controlling attention. Fuzzy words that cannot provide clear text content activate the fusiform gyrus of the ventral stream of the visual-spatial network, strengthening the function of orthographic processing.

How Does Visual Temporal Processing Affect Chinese Character Reading in Children With Dyslexia? From the Perspective of Inhibition

Given that inhibition interacts with visual temporal processing (VTP), the past evidence regarding the influence of VTP on the Chinese character reading of children with dyslexia may not disclose the whole picture without considering inhibition. Thus, the present study is among the first to investigate VTP and cognitive inhibition as well as their relationships to Chinese character reading. We compared the performances of 62 Chinese-speaking children with dyslexia in primary school (n = 62, Mage = 11.36 years) on VTP and inhibition tasks to those in a chronological-age-matched group (CA; n = 62, Mage = 11.57 years) and reading-level-matched group (RL; n = 62, Mage = 8.98 years). The results revealed that children with dyslexia performed worse than both the CA-matched and RL-matched groups in VTP and inhibition after controlling for age, nonverbal intelligence, and attention. Moreover, the relationship between VTP and Chinese character reading was moderated by inhibition in children with dyslexia. VTP is positively related to Chinese character reading, but this relationship is observed only at higher levels of inhibition. Our results suggest that inhibition plays a potential role in VTP and Chinese character reading, especially for those with dyslexia whose proficiency in inhibition is not as intact as that of typically developing children.

The neural correlates of sub-lexical semantics and its integration with the lexical meaning in reading Chinese characters

The semantic neural routes in contemporary models of visual word recognition are mainly constructed based on lexical-semantic processing. However, the neural bases of processing semantic cues embodied in sub-lexical units are less clear. The current fMRI study takes the ideographic property of Chinese characters (The semantic radical can provide a semantic cue for the character's meaning) to explore the brain mechanisms of sub-lexical semantic processing and its interaction with lexical-semantic processing in a lexical decision task. The GLM results and further ROI analysis revealed that the lexical-semantic processing relied on the left posterior Middle Temporal Gyrus (pMTG) and Angular Gyrus (AG); the sub-lexical semantic processing relied on the left middle MTG (mMTG) and AG; their integration relied on the left Anterior Temporal Lobe (ATL). It sheds light on investigating the neural circuit of the semantic processing in visual word reading.

Development and validation of the simplified Chinese Author Recognition Test: Evidence from eye movements of Chinese adults in Mainland China

BackgroundIt is well evident that individuals' levels of print exposure are significantly correlated with their reading ability across languages, and an author recognition test is commonly used to measure print exposure objectively. For the first time, the current work developed and validated a Simplified Chinese Author Recognition Test (SCART) and examined its role in explaining Chinese online reading.MethodsIn Study 1, we constructed the SCART for readers of simplified Chinese and validated the test using data collected from 203 young adults in Mainland China. Participants were measured on the SCART and three self‐report tasks about their reading experiences and habits. Study 2 recruited additional 68 young adults in Mainland and measured their print exposure (with the same tasks used in Study 1), reading‐related cognitive ability (working memory, rapid automatic naming, Chinese character reading, and vocabulary knowledge), and Chinese online reading via an eye‐tracking passage reading task.ResultsResults of Study 1 support the high reliability and validity of the SCART. Results of Study 2 indicate that SCART scores significantly predicted participants' online reading processing while controlling for subjective reading experiences and habits, and reading‐related cognitive abilities. Across two studies, we found converging evidence that the in‐depth recognition of the authors (i.e., participants have read the books written by these authors) appears to be a better indicator of print exposure than the superficial recognition of the author names.ConclusionsTaken together, this work filled in the gap in the literature by providing an evidence‐based, objective print exposure measure for simplified Chinese and contributes to a broader understanding of print exposure and online reading processing across different writing systems.

Chinese heritage children learning to read characters: The effects of group reading and frequency of character exposure

Learning to read Chinese has been the main focus of Chinese heritage language education. The frequency of exposure to orthography–phonology and orthography–semantics correspondences and radical awareness play a significant role in character learning. However, limited exposure to characters in Chinese textbooks and the lack of explicit instruction on phonetic radicals have been proposed as limitations of conventional instruction methods used with Chinese heritage language learners. The current study assessed the efficacy of providing frequent character exposure in group reading activities for Chinese heritage children in their early learning to read Mandarin Chinese through a teaching method called Progressive Character Reading. The effectiveness of the teaching method on Chinese character acquisition and Chinese reading comprehension was examined through a quasi-experimental framework that compared a group of children undergoing the new teaching method (experimental group, n = 20) with a group of learners experiencing the traditional textbook-based instruction (control group, n = 20). Significant differences in gains between these two groups were found in measures of Chinese character reading, character–picture matching and Chinese sentence comprehension. These results suggest that group reading activities with frequent character exposure can increase learning for Chinese heritage language learners over that associated with conventional textbook-based instruction.

The difficulty and challenge in Chinese children’s character reading: An analysis based on Chinese curriculum standards and Chinese character reading research

Chinese character reading is the focus of Chinese teaching in the lower grades of primary school, and it is also a difficult point and challenging problem in the transition from kindergartens (K3) to primary school. To understand the learning slope of children's Chinese character reading in this transition, this study assessed the requirements of Chinese curriculum standards for compulsory education over the years based on the number of Chinese characters being learned by children in the lower grades of primary school. The results showed that the requirement of 1600 Chinese characters was, is, and will be the “should level” required at this stage of education. Comparing it with the levels achieved by children in kindergartens and primary schools in the empirical research from 2005 to 2021, it was found that the slope of children's Chinese character reading was not in the transition between K3 and Grade 1 but rather between Grades 1 and 2. The study proposed that to alleviate the slope in this transition, we should pay more attention to Chinese character teaching in Grade 2, improve the abilities of Grade 2 students’ Chinese character reading, and help them reach the requirements of the curriculum standards, in order to prevent the pressure of Chinese character reading from Grade 2 flooding back into Grade 1, causing parents to worry about their children's Chinese character reading before entering primary school.

Cumulative genetic score of KIAA0319 affects reading ability in Chinese children: moderation by parental education and mediation by rapid automatized naming

KIAA0319, a well-studied candidate gene, has been shown to be associated with reading ability and developmental dyslexia. In the present study, we investigated whether KIAA0319 affects reading ability by interacting with the parental education level and whether rapid automatized naming (RAN), phonological awareness and morphological awareness mediate the relationship between KIAA0319 and reading ability. A total of 2284 Chinese children from primary school grades 3 and 6 participated in this study. Chinese character reading accuracy and word reading fluency were used as measures of reading abilities. The cumulative genetic risk score (CGS) of 13 SNPs in KIAA0319 was calculated. Results revealed interaction effect between CGS of KIAA0319 and parental education level on reading fluency. The interaction effect suggested that individuals with a low CGS of KIAA0319 were better at reading fluency in a positive environment (higher parental educational level) than individuals with a high CGS. Moreover, the interaction effect coincided with the differential susceptibility model. The results of the multiple mediator model revealed that RAN mediates the impact of the genetic cumulative effect of KIAA0319 on reading abilities. These findings provide evidence that KIAA0319 is a risk vulnerability gene that interacts with environmental factor to impact reading abilities and demonstrate the reliability of RAN as an endophenotype between genes and reading associations.

Relationships Between First and Second Language Phonological Awareness and Rapid Automatized Naming in Chinese Children with Dyslexia

Relationships Between First and Second Language Phonological Awareness and Rapid Automatized Naming in Chinese Children with Dyslexia

The relationship between auditory temporal processing, phonological processing and reading in Hong Kongese and Taiwanese children: from kindergarten to primary school (La relación entre el procesamiento temporal auditivo, el procesamiento fonológico y la lectura en los niños hongkoneses y taiwaneses: de preescolar a primaria)

ABSTRACT This study aims to compare auditory temporal processing and phonological processing across locations and age levels and to test the direct and indirect effects of auditory temporal and phonological processing on proficiency in Chinese character reading. We recruited 108 typically developing children — 25 and 24 kindergarteners from Taiwan and Hong Kong, respectively, and 34 and 25 primary school students from Taiwan and Hong Kong, respectively. Our findings showed that, before learning PCS, the languages’ phonological complexity did not affect the importance of ATP in Chinese reading. Also, we found the use of PCS could lead to a direct effect from students’ ATP to Chinese character reading as well as through phonological awareness. Our findings indicated that ways of learning to read influence children’s patterns of cognitive and linguistic abilities, which should be considered in teaching designs for reading.

How do the component skills affect Chinese FL reading comprehension? A study based on ridge regression analysis

Abstract This study aimed to investigate the effect of reading components (including Chinese character knowledge, morphological knowledge, vocabulary knowledge, grammar knowledge, and lexical inference) on the reading comprehension of 44 Malaysian child learners of Chinese as a foreign language (CFL). Measures of Chinese character knowledge, morphological knowledge, receptive vocabulary, vocabulary synonym, lexical inference, word order, grammatical judgment, and reading comprehension were used. Drawing upon ridge regression, the study found that grammar knowledge (measured by word order and grammatical judgment) had the largest effect on reading comprehension, followed by morphological knowledge and vocabulary knowledge (measured by receptive vocabulary and vocabulary synonym). Lexical inference and Chinese character knowledge had the least effects on reading comprehension. The findings of the study are discussed with pedagogical implications and future research suggestions.
