Purpose: We examined the role of distal (parents' education, family's income, parents' expectations, and parents' attitudes to the home teaching of literacy) and proximal (formal and informal home literacy environment, access to literacy resources, and extracurricular activities) parental factors in children's early literacy skills and whether the relations vary across affluent and disadvantaged societies in China. Method: Five hundred fifty-three third-year kindergarten Chinese children (M[subscript age] = 74.59 months) were recruited from Jining, Luqiao, and Mapo and were assessed on measures of phonological awareness, vocabulary, pinyin knowledge, and word reading. Their parents filled out a questionnaire on their education and income as well as on the frequency of engaging in different home literacy activities, their expectations and attitudes to the home teaching of literacy, and their children's extracurricular activities. Results: Results of multigroup analyses and mediation analyses revealed both direct and indirect effects of both distal and proximal parental factors on emergent literacy skills and word reading. In addition, the models were strikingly similar across the two settings. Conclusion: The findings suggest that the pathways of differential influences from parental factors to children's early literacy skills may be similar across socioeconomic contexts.

The Triangle Model of Reading proposes that phonology, orthography, and semantics are crucial to understand word reading and reading disability (RD). Morphology has been added as a binding agent to this model. However, it is unclear how these variables relate to word reading in children with attention deficit/hyperactivity disorder (ADHD) or comorbid ADHD and RD (ADHD+RD). This study examined the performance of Chinese children with RD, ADHD, or ADHD+RD in phonology, orthography, semantics, and morphology, and investigated whether morphology made an additional contribution beyond the other skills in explaining word reading fluency. Participants were 151 Grade 1 to 3 Chinese students: RD (n = 31), ADHD (n = 43), ADHD+RD (n = 27), and typically developing controls (TD, n = 50). Results indicated that children with ADHD+RD (a) showed similar performance to RD and ADHD in tone awareness, orthographic legality, and homophone morpheme awareness; (b) had similar performance to RD but worse than ADHD in phonology, semantics, and morpheme production; and (c) had more severe deficits than RD and ADHD in orthographic reversal, morpheme identification, and homograph awareness. Morphology significantly predicted word reading fluency beyond the other skills, and its predictive effect was more salient for ADHD+RD, ADHD, and TD. The findings provide evidence of both shared and additive effects of RD and ADHD. Morphology may be an important diagnostic factor in identifying Chinese reading and behavioral deficit groups and a worthwhile target for intervention.

A long-standing question in developmental science is how the neurodevelopment of the brain influences cognitive functions. Here, we examined the developmental change of resting EEG power and its links to vocabulary acquisition in school-age children. We further explored what mechanisms may mediate the relation between brain rhythm maturation and vocabulary knowledge. Eyes-opened resting-state EEG data were recorded from 53 typically-developing Chinese children every 2 years between the ages of 7 and 11. Our results showed first that delta, theta, and gamma power decreased over time, whereas alpha and beta power increased over time. Second, after controlling for general cognitive abilities, age, home literacy environment, and phonological skills, theta decreases explained 6.9% and 14.4% of unique variance in expressive vocabulary at ages 9 and 11, respectively. We also found that beta increase from age 7 to 9 significantly predicted receptive vocabulary at age 11. Finally, theta decrease predicted expressive vocabulary through the effects of phoneme deletion at age 9 and tone discrimination at age 11. These results substantiate the important role of brain oscillations at rest, especially theta rhythm, in language development. The developmental change of brain rhythms could serve as sensitive biomarkers for vocabulary development in school-age children, which would be of great value in identifying children at risk of language impairment.

We examined the developmental relationship between cognitive-linguistic skills (nonverbal IQ, vocabulary, phonological awareness, rapid automatised naming [RAN]), home environment factors (direct teaching, shared book reading, access to literacy resources, parents' expectations, family's socioeconomic status [SES]), and pinyin letter knowledge in kindergarten, pinyin reading accuracy at the beginning of Grade 1, and pinyin reading fluency at the middle of Grade 1 in a sample of 159 Chinese children (mean age = 72.70 months). Results showed that phonological awareness, RAN, and direct teaching were associated with pinyin letter knowledge. RAN consistently predicted pinyin reading accuracy and fluency. Moreover, parents' expectations and family's SES predicted pinyin reading indirectly through RAN and direct teaching. These findings suggest that the cognitive-linguistic and home environment predictors of pinyin reading are similar to those for Chinese reading, except that vocabulary and access to literacy resources may be less important for pinyin reading.

Although several studies have examined the role of home literacy environment (HLE) in learning to read in Western societies, little is known about the role of HLE in Chinese reading. In addition, the few studies in Chinese have not tested the possible effects of HLE on reading comprehension. Thus, the purpose of this study was to examine the direct and indirect effects of different aspects of HLE (formal literacy experiences, informal literacy experiences, and access to literacy resources) on reading comprehension in Chinese. One hundred fifty-nine third year kindergarten children (70 girls and 89 boys; M[subscript age] = 72.62 months) participated in the study. In kindergarten, they were assessed on emergent literacy skills (vocabulary, phonological awareness, pinyin knowledge, rapid naming), in Grade 1, on word reading, and, in Grade 2, on reading comprehension. In addition, parents filled out a questionnaire on their education and income, the frequency of different HLE activities, the number of children's books at home, and their expectations, when their children were in kindergarten. Results of structural equation modeling showed that formal literacy experiences predicted reading comprehension through the effects of pinyin knowledge on word reading. Access to literacy resources predicted reading comprehension through the effects of rapid naming, phonological awareness, and vocabulary. Finally, informal literacy experiences did not predict any of the emergent literacy skills or reading outcomes. Our findings provide only partial support of the home literacy model and suggest that the culture in which environmental effects take place may determine what aspects of the home literacy environment contribute to children's reading performance and what not.

The purpose of this study was to examine which of the components of executive functions (EF)--inhibition, shifting, and working memory--predict reading and mathematics achievement and if the effects of these components are the same across two cultures (Western and East Asian). One hundred twenty English-speaking Canadian (65 females, 55 males; M[subscript age] = 82.12 months) and 181 Mandarin-speaking Chinese (82 females, 99 males; M[subscript age] = 85.85 months) children were assessed on nonverbal IQ, speed of processing, rapid naming, inhibition (Color-Word Stroop), shifting (Planned Connections), working memory (Digit Span Forward and Backward), reading (word identification and reading comprehension), and mathematics (numerical operations and math reasoning). The results of structural equation modeling indicated first that among the EF components only working memory predicted reading and mathematics in the Canadian sample, while inhibition and working memory predicted reading and mathematics in the Chinese sample. The results also showed that inhibition was a stronger predictor of reading and mathematics in the Chinese sample. Taken together, these findings suggest that not all EF components are equally important for reading/mathematics and that culture may influence the relations between specific EF components and academic achievement.

The authors examined whether different measures of print exposure assess the same underlying concept and how these different measures relate to vocabulary breadth and depth. One hundred forty-seven students attending the third year of kindergarten in Jining, China, were assessed on nonverbal IQ, vocabulary breadth and depth, and their knowledge of book titles. Parents also participated in the study by filling out a questionnaire on the frequency of shared book reading and the number of children's books at home, recording their daily parent-child reading activities (diary), and completing the children's title and author recognition checklists. Results of exploratory factor analysis indicated that the measures of print exposure were loading on three interrelated factors. The items measuring the frequency of shared book reading at home along with diary formed one factor, the children's title recognition checklist and number of children's books at home formed a second factor, and children's knowledge of book titles formed a third factor. In addition, the results of hierarchical regression analyses indicated that whereas all factors accounted for unique variance (3-6%) in vocabulary breadth, only children's knowledge of book titles predicted vocabulary depth, after controlling for children's age, parents' education and income, and children's nonverbal IQ. Taken together, these findings suggest that different measures of print exposure may capture different aspects of print exposure and that these aspects may exert a different role in vocabulary breadth and depth.

Although rapid automatized naming (RAN) is one of the best predictors of reading across languages, its nature remains elusive. In the present study, we aim to elucidate the nature of RAN by examining the cognitive and environmental correlates of RAN. One hundred forty-one second-year kindergarten Chinese children (71 girls, 70 boys; mean age = 58.99 months) were assessed on measures of nonverbal cognitive ability, attention, visual processing, conceptual processing, semantic processing, phonological processing, short-term memory, articulation, speed of processing, RAN (digits and objects), and discrete naming. We also collected information on mothers' education and occupation, and children's home learning experiences. The results showed that formal home learning experiences, visual processing, phonological processing, and articulation were unique correlates of both RAN tasks. Semantic processing also correlated significantly with RAN objects. However, controlling for the effects of discrete naming eliminated the effects of most subprocesses on RAN. These findings suggest that RAN is indeed multicomponential, but not all components contribute the same way to RAN performance. Theoretical and practical implications of these findings are discussed.

Both reading difficulties (RD) and mathematics difficulties (MD) are common neurodevelopmental disorders. The co-occurrence of RD and MD, known as comorbid RDMD, is estimated to range between 21% and 45% of children with learning disabilities. Deficits in working memory have been reported in both RD and MD groups, as well as among comorbid RDMD. However, previous comorbidity studies have only examined the role of some components of working memory, and they do not strictly match their groups on relevant reading and mathematics tasks. Thus, the purpose of this study is to examine the nature of working memory deficits in comorbid RDMD after matching groups based on reading and mathematics tasks. We assessed four groups of children (RD [n = 21, Mage = 10.96 years], MD [n = 24, Mage = 11.04 years], comorbid RDMD [n = 26, Mage = 10.90 years], and chronological-age controls [n = 27, Mage = 10.96 years]) on measures of the phonological loop (word span and digit span forward tasks), central executive (complex word and digit span), and updating tasks (word and digit 2-back). The results of ANCOVA (covarying for gender and non-verbal IQ) showed first that the RD and RDMD groups performed significantly worse than the MD and control groups in both measures of the phonological loop. For the central executive and updating tasks, we found an effect based on stimulus type. For word-related tasks, the RD and comorbid RDMD groups performed worse than the MD and control groups, and for number-related tasks, the MD and comorbid RDMD groups performed worse than the RD and control groups. Taken together, our findings provide support for the correlated liability model of comorbidity, which indicates that working memory deficits experienced by the RDMD group are an additive combination of deficits observed in the RD and MD groups, suggesting that working memory tasks used to examine underlying deficits in reading and/or mathematics difficulties may dictate whether or not significant group differences are found.

The purpose of the present study was twofold: (a) to examine the extent to which Chinese dyslexic children experience deficits in phonological and orthographic processing skills and (b) to examine if Chinese dyslexia is associated with deficits in Planning, Attention, Simultaneous, and Successive (PASS) processing. A total of 27 Grade 4 children with dyslexia (DYS), 27 Grade 4 chronological age (CA) controls, and 27 Grade 2 reading age (RA) controls were tested on measures of phonological awareness, rapid naming, phonological memory, PASS, reading accuracy, and reading fluency. The results indicated that the DYS group performed significantly poorer than the CA and RA groups on both measures of phonological awareness and on a measure of orthographic processing but comparably to the RA group on a measure of rapid naming and both measures of phonological memory. In regard to the PASS processing skills, the DYS group performed worse than the CA controls on Successive and Simultaneous processing but comparably to the RA group on all PASS processing skills. Implications of these findings for early identification and intervention of reading difficulties are discussed. (Contains 3 tables.)

The purpose of this 4-year longitudinal study was to specify the direction of the relationship between RAN and word reading (accuracy and fluency) in Chinese. This is important in light of arguments that the developmental relationships between RAN and reading can disclose changes in the reading processes underlying reading as development proceeds. One hundred thirty-five Mandarin-speaking Chinese children (65 boys, 70 girls;Mage = 96.40 months) were assessed on RAN (digits), word-reading accuracy (Character Recognition), and word-reading fluency (One-Minute Reading). The children were assessed on the same measures when they were in Grades 3, 4, and 5. The results of path analysis indicated that the effects between RAN and word reading were unidirectional and subject to the type of reading outcome: Only RAN predicted word reading and only when word reading was operationalized with a reading fluency measure.

We examined (a) the cross-lagged relationships between the home learning environment and academic achievement in Chinese, and (b) whether parents’ socioeconomic status (SES) and child's gender moderate the relations. One hundred seventy-seven Chinese children were followed from Grade 1 to Grade 2 and were assessed on reading and mathematics. Their parents also responded to a questionnaire assessing the frequency of engaging in different home literacy and numeracy activities. Results showed that reading ability in Grade 1 negatively predicted informal home literacy activities in Grade 2. In turn, mathematics ability in Grade 1 negatively predicted formal home numeracy activities in Grade 2. Neither parents’ SES nor child's gender moderated any of the observed cross-lagged relationships. These findings suggest first that different facets of the home learning environment may relate to reading and mathematics in Chinese. Second, once children go to Grade 1, the relationship between home learning environment and academic achievement becomes unidirectional: early reading/mathematics ability predicts future home literacy/numeracy activities and the effect is negative. This suggests that parents engage more frequently in home activities when they notice that their children experience difficulties in reading or mathematics. However, it is also possible that parents change their teaching in order to be in accord with the expectations of the school system. [ABSTRACT FROM AUTHOR]

The present study examined both the development of behavioral and electrophysiological rhythm processing and their contribution to phonological awareness and word reading in Chinese. We followed a sample of 47 Mandarin-speaking Chinese children from age 9 (Grade 3) to age 11 (Grade 5). Results showed first a significant improvement over time in behavioral beat perception and in P3as for small beat changes. Second, behavioral and neural beat sensitivities at age 9 predicted phonological awareness (phoneme deletion and tone identification) at age 11 and its development over the two-year span of the study. Neural beat sensitivities at age 9 also explained unique variance in reading accuracy (but not reading fluency) at age 11 and its two-year development. Taken together, these findings suggest that rhythm and Chinese reading-related skills are intricately related. Neural rhythm sensitivities could serve as predictive biomarkers for the development of phonological awareness and reading in Chinese school-age children. [ABSTRACT FROM AUTHOR]

Previous studies have shown that the ability to simultaneously process multiple items when these appear in serial format (called "cascaded" processing) is an important element of reading fluency. However, most evidence in support of cascaded processing comes from studies conducted in European orthographies. Thus, the purpose of the current study was to examine whether the same findings generalize to nonlinear and nonalphabetic orthographies (i.e., Korean and Chinese). Serial and discrete naming of digits and objects were measured in a sample of 610 Chinese and Korean children from Grades 1, 3, 5, and 6. Children were also assessed on discrete word reading and on word- and text-reading fluency. Results of hierarchical regression analysis showed that discrete naming was the main predictor of discrete word reading in both languages as early as Grade 1. Serial digit naming was the main predictor of word-reading fluency across grades and languages. Finally, serial object naming made a unique contribution to word- and text-reading fluency in Chinese upper grades. Taken together, these findings suggest that, beyond accurate and fast word recognition, there is a universal multi-item (or cascaded) processing skill involved in serial naming and reading fluency., (Copyright © 2022 Elsevier Inc.

The purpose of this commentary is to discuss the key points addressed in the papers included in the special issue on child and adolescent development in China. The reviews included here suggest that, for the most part, child and adolescent development in China is not significantly different from that reported in Western countries. I further argue that to better understand the role of Chinese culture in academic achievement (this appears to be the major outcome in most studies), we need more cross-cultural studies that contrast the role of multiple factors (e.g., cognitive, linguistic, environmental) simultaneously., (© 2019 Wiley Periodicals, Inc.)

We examined in a series of studies the mechanism that may underlie the relationship between Rapid Automatized Naming (RAN) and reading (accuracy and fluency) in Mandarin Chinese. Study 1 examined the "arbitrary" connections hypothesis in a sample of Grade 2 children (N=182). Study 2 contrasted the phonological processing, orthographic processing, and speed of processing hypotheses in a sample of Grade 2 children followed until Grade 5 (N=72). Finally, Study 3 contrasted the same hypotheses in a sample of Grade 4 children with dyslexia (n=30) and chronological-age controls (n=30). The results indicated that (a) RAN is unrelated to Paired Associate Learning (PAL) tasks that tap the ability to form arbitrary connections between characters and their pronunciation, (b) controlling for nonverbal IQ and orthographic processing was sufficient to explain the RAN-reading accuracy relationship but not the RAN-reading fluency relationship, and (c) the observed differences between dyslexics and controls in RAN diminished after controlling for orthographic processing. Taken together, these findings suggest that RAN is related to reading accuracy (and partly to reading fluency) because children must access orthographic representations from long-term memory. Although accessing these representations is sufficient for accurate word recognition, it is not sufficient for fluent reading, which also requires efficient parafoveal processing., (Copyright © 2014 Elsevier Inc.
