This study examined the relations among family socialization, loneliness, linguistic skills, and reading comprehension in 78 Mandarin-speaking Chinese third graders with a mean age of 8.67 years old. The participants were administered a battery of tasks to assess their non-verbal intelligence, linguistic-skills, word reading, and Chinese reading comprehension, and asked to complete loneliness, trait anxiety, family socialization, and demographic questionnaires. Regression analysis showed that family socialization, loneliness, and linguistic-skills were significant predictors of reading comprehension after controlling for SES, non-verbal intelligence, trait anxiety, and word reading. Mediation analysis showed that linguistic skills fully mediated the relation between loneliness and reading comprehension after accounting for the variance of controlled variables. These findings suggest that family socialization and loneliness significantly affect the development of reading comprehension.

The co-occurrence of reading comprehension difficulties for first language (L1) Chinese and second language (L2) English and associated longitudinal cognitive-linguistic correlates in each language were investigated. Sixteen poor comprehenders in English and 16 poor comprehenders in Chinese, 18 poor readers in both, and 18 children with normal performance in both were identified at age 10. The prevalence rate for being poor in both was 52.94%, suggesting that approximately half of children who are at risk for Chinese reading comprehension difficulty are also at risk for English reading comprehension difficulty. Chinese word reading, phonological, and morphological awareness were longitudinal correlates of poor comprehension in Chinese. English word reading and vocabulary were longitudinal correlates of poor comprehension in English. Chinese phonological awareness was an additional correlate of poor comprehension in English. Moreover, poor comprehenders in both Chinese and English showed slower rapid automatized naming scores than the other groups. Findings highlight some factors that might be critical for reading comprehension in L1 Chinese and L2 English; fluency is likely to be a critical part of reading comprehension across languages.

In this study, we investigated the contribution of morphological awareness (MA) in one language to word reading and vocabulary in another language in Hong Kong Cantonese–English speaking children, who learn Chinese and English in school in parallel from the age of 3.5 years onwards. Our sample consisted of 97 Cantonese–English speaking children including 34 first graders, 28 second graders, 21 third graders and 14 fourth graders. All children were administered tasks of nonverbal reasoning, phonological awareness in Chinese, and lexical compounding, vocabulary, and word reading in both Chinese and English. Results revealed that second language (L2) English MA significantly contributed to first language (L1) Chinese word reading and Chinese vocabulary knowledge. However, L1 Chinese MA was not uniquely associated with either L2 English word reading or vocabulary knowledge. Findings suggest that among Chinese children learning in Chinese medium of instruction schools with English taught as a second language, compounding skills in English may be useful for facilitating Chinese word reading and vocabulary acquisition, but Chinese compounding skills are not uniquely important for learning in English.

In the present study, we used a three-time point longitudinal design to investigate the associations of morphological awareness to word reading and spelling in a small group of those with and without dyslexia taken from a larger sample of 164 Hong Kong Chinese children who remained in a longitudinal study across ages 6, 7 and 8. Among those 164 children, 15 had been diagnosed as having dyslexia by professional psychologists, and 15 other children manifested average reading ability and had been randomly selected from the sample for comparison. All children were administered a battery of tasks including Chinese character recognition, word dictation, morphological awareness, phonological awareness and rapid automatized naming. Multivariate analysis of variance and predictive discriminate analysis were performed to examine whether the dyslexic children showed differences in the cognitive-linguistic tasks in comparison with controls. Results suggested that the dyslexic groups had poorer performance in morphological awareness and RAN across all 3 years. However, phonological awareness was not stable in distinguishing the groups. Findings suggest that morphological awareness is a relatively strong correlate of spelling difficulties in Chinese, but phonological awareness is not. Copyright © 2017 John Wiley & Sons, Ltd.

This study investigated the reciprocal relationship between Chinese syntactic awareness and Chinese reading comprehension among 129 Hong Kong Chinese-speaking children participating in a 10-year longitudinal study. All children were tested on tasks of nonverbal reasoning, phonological awareness, morphological awareness, vocabulary knowledge, word reading, syntactic judgment/correction, conjunction cloze, and reading comprehension. Results showed that children's syntactic awareness at age 11 was significantly associated with their reading comprehension at age 12 even after taking into account early nonverbal reasoning ability, phonological awareness, morphological awareness, word reading, vocabulary knowledge, and the previous year's reading comprehension. The results also showed that children's performance in reading comprehension at age 11 accounted for substantial variance in syntactic awareness at age 12. These findings suggest that the relation between syntactic awareness and reading comprehension is bidirectional, and they may mutually reinforce each other during reading development in Cantonese-speaking children.

The current study adopted the MMN additivity approach to examine the pre-attentive perceptual integration of vowels and tones. Twenty Cantonese listeners participated in the ERP experiment. Using the passive oddball paradigm, we elicited tone-MMN, vowel-MMN and double-MMN in the speech condition; and fundamental frequency-MMN, formant frequency-MMN and double-MMN in the non-speech condition. In both conditions, the double-MMNs were significantly smaller in amplitude than the sum of single feature MMNs. Morphological comparisons showed no significant difference in the latency and topographic patterns between vowel-MMN and tone-MMN, and marginal significant differences between formant frequency-MMN and fundamental frequency-MMN. Collectively, results reflect the perceptual integration of tones and vowels at the phonological level, and partial integration of fundamental frequency and formant frequency at the auditory level.

This study investigated Chinese children’s development of sensitivity to positional (orthographic), phonological, and semantic cues of radicals in encoding novel Chinese characters. A newly designed picture-novel character mapping task, along with nonverbal reasoning ability, vocabulary, and Chinese character recognition were administered to 198 kindergartners, 172 second graders and 165 fifth graders. Children’s strategies in using positional, phonological, and semantic cues of radicals varied across grades. The higher the children’s grade level, the more commonly children used semantic and positional cues of radicals. Regression analyses showed that the contribution of semantic radical awareness for explaining Chinese character reading increased as children’s grade increased, whereas the contribution of positional regularity awareness decreased. These findings suggest that learning Chinese characters involves a transition from a sound- and position-based approach to a meaning-based approach.

The nature of the relations among morphological awareness, vocabulary and word reading in Chinese children remains relatively unclear. The present study aimed to distinguish between sublexical morphological awareness, referring to the ability to use the meaning cues of semantic radicals embedded in a compound character, and lexical level morphological awareness, defined as the ability to understand and manipulate single characters (i.e., morphemes) comprising Chinese compound words, on word reading. We also examined the role of vocabulary knowledge on the relation between morphological awareness and word reading at both the sublexical and lexical levels. A group of 172 Chinese second graders were administered measures of sublexical and lexical level morphological awareness, vocabulary knowledge, phonological awareness, orthographic knowledge, nonverbal ability, and word reading. Both sublexical and lexical levels of morphological awareness were moderately correlated with word reading. Vocabulary knowledge appeared to partially mediate the effect of sublexical morphological awareness on word reading, but it fully mediated the effect of lexical level morphological awareness on word reading. These results suggest that sublexical and lexical level morphological awareness play distinct roles in Chinese word reading; vocabulary knowledge is an important factor influencing the relation between morphological awareness and word reading in Chinese.

We investigated the influence of nonparental caregivers, such as foreign domestic helpers (FDH), on the home language spoken to the child and its implications for vocabulary and word reading development in Cantonese- and English-speaking bilingual children. Using data collected from ages 5 to 9, we analyzed Chinese vocabulary, Chinese character recognition, English vocabulary, and English word reading among 194 native Cantonese-speaking children in Hong Kong with English-speaking FDHs (n = 46), children with Cantonese-speaking FDHs (n = 32), and children with no FDHs who were spoken to in Cantonese (n = 116). Multilevel modeling results showed potential advantages in initial English vocabulary and disadvantages in initial Chinese character recognition among children in the English-speaking FDH group, with no evidence for compounding or diminished costs or benefits over time. Results are discussed in relation to both theoretical and practical aspects of home language and literacy development.

Visual expertise in distinguishing words from objects and word-like stimuli is a fundamental skill that is important for children to become proficient readers. This expertise can be indexed by the N1 component of ERPs at the neural level. However, the nature of N1 tuning for print is controversial in terms of onset of the latency, lateralization and the neural mechanism of the N1. This study aimed to investigate whether two groups of Chinese children could discriminate characters/character-like stimuli from visual controls (i.e., coarse N1 tuning) and distinguish characters from character-like stimuli (i.e., fine N1 tuning). We also explored the cognitive-linguistic correlates of N1 tuning. Seventeen children in the younger group (M=7.7 years) and 13 in the older group (M=9.4 years) were all required to finish a character decision task with character, pseudocharacter, noncharacter, and stroke combination conditions using ERP testing. Both the pseudocharacters and noncharacters were unpronounceable, and the main difference between the two conditions was in orthographic presentation (i.e., radical position). Children were also administered measures of reading fluency, reading accuracy, RAN, phonological skill and vocabulary knowledge. ERP results showed that a significantly larger N1 was observed in the characters, pseudocharacters, and noncharacters as compared to the stroke combinations in both groups. The N1 for characters and pseudocharacters was also significantly larger than that for noncharacters in both groups. Both coarse and fine N1s were larger for younger children than for older children, and the N1 was bilateral in younger children, but left lateralized in older children. Correlational analyses showed that the coarse N1 tuning of real characters versus visual controls was moderately correlated with reading fluency and accuracy but not RAN, phonology, or vocabulary. Taken together, our study suggests that both coarse and fine N1 tuning occurs in both younger and older children, when performing character decisions. Under such task demands, orthography, rather than phonology or semantics, seems to be the driver of coarse N1 tuning for print in Chinese children.

Children traditionally learn to read Chinese characters by rote, and thus stretching children’s memory span could possibly improve their reading in Chinese. Nevertheless, 85% of Chinese characters are semantic-phonetic compounds that contain probabilistic information about meaning and pronunciation. Hence, enhancing children’s metalinguistic skills might also facilitate reading in Chinese. In the present study, we tested whether training children’s metalinguistic skills or training their working-memory capacity in 8 weeks would produce reading gains, and whether these gains would be similar in Chinese and English. We recruited 35 second graders in Hong Kong and randomly assigned them to a metalinguistic training group (N = 13), a working-memory training group (10), or a waitlist control group (12). In the metalinguistic training, children were taught to analyze novel Chinese characters into phonetic and semantic radicals and novel English words into onsets and rimes. In the working-memory training, children were trained to recall increasingly long strings of Cantonese or English syllables in correct or reverse order. All children were tested on phonological skills, verbal working memory, and word reading fluency in Chinese and in English before and after training. Analyses of the pre- and post-test data revealed that only the metalinguistic training group, but not the other two groups, showed significant improvement on phonological skills in Chinese and English. Working-memory span in Chinese and English increased from the pre- to post-test in the working-memory training group relative to other two groups. Despite these domain-specific training effects, the two training groups improved similarly in word reading fluency in Chinese and English compared to the control group. Our findings suggest that increased metalinguistic skills and a larger working-memory span appear equally beneficial to reading fluency, and that these effects are similar in Chinese and English.

Visual specialization for print is an essential structural element of fluent reading. Previous research suggests that lateralization of N1 print tuning may depend on both the writing system and the skill level. Here, we tested which of these effects was more prominent in beginning readers of Chinese (L1) and English (L2). Using an ERP measure with an implicit one-back repetition detection task, we investigated the neural basis of visual specialization for print in Chinese and English among eleven 7-to-8-year-old Hong Kong children, who were learning to read Chinese and English in parallel, though showing lower skills in English. N1 print tuning was found for both Chinese and English words, but was bilateral for Chinese and right-lateralized for English. In addition, the specialization effect of print started as early as in the time window of the P1, with a reduced P1 for Chinese and English words as compared to the visually matched control stimuli. These findings suggest that Chinese readers in 2nd grade show clear visual specialization for both Chinese and English print and that right-lateralized N1 specialization may be driven by less reading experience in English rather than by writing-specific effects induced by Chinese.

This research aimed to explore the relation between syntactic awareness and writing composition in 129 Hong Kong Chinese children. These children were from a ten-year longitudinal project. At each year, a number of measures were administered. The 129 children's data of nonverbal reasoning at age 4, phonological awareness, morphological awareness, vocabulary knowledge at age 8, reading comprehension at age 12 and syntactic awareness and writing composition skills at ages 11 and 12 were included in this study. Syntactic awareness was longitudinally and uniquely predictive of Chinese children's writing composition, and children's performance in early writing composition was uniquely associated with their later syntactic skills, even when controlling for the contributions from age, nonverbal and verbal abilities, phonological awareness, and morphological awareness. The relationship between syntactic awareness and writing composition was mediated by children's performance in reading comprehension. These findings may suggest a reciprocal relation between syntactic awareness and writing composition, and this association may vary with ability in reading comprehension in Chinese children.

This study examined the role of visual statistical learning in reading and writing and its relationship to orthographic awareness in Hong Kong Chinese children with and without developmental dyslexia. Thirty-five 7- to 8-year-old children with developmental dyslexia and 37 chronologically age-matched controls were tested on visual statistical learning, orthographic awareness, nonverbal cognitive ability, Chinese word reading, and word dictation tasks. Visual statistical learning was assessed using a triplet learning paradigm that required children to detect the temporal order of visual stimuli. Orthographic awareness was measured with a novel character invention task that required children to create pseudocharacters using untaught stroke patterns according to the rules of Chinese character orthography. Children with dyslexia performed significantly worse than their age-matched controls on both the visual statistical learning and orthographic awareness tasks. Furthermore, visual statistical learning was significantly associated with orthographic awareness and word reading. These findings suggest that Chinese children with dyslexia are impaired in visual statistical learning and that such deficits may be related to disrupted orthographic learning abilities, thereby contributing to their reading difficulties.

The process of reading words depends heavily on efficient visual skills, including analyzing and decomposing basic visual features. Surprisingly, previous reading-related studies have almost exclusively focused on gross aspects of visual skills, while only very few have investigated the role of finer skills. The present study filled this gap and examined the relations of two finer visual skills measured by grating acuity (the ability to resolve periodic luminance variations across space) and Vernier acuity (the ability to detect/discriminate relative locations of features) to Chinese character-processing as measured by character form-matching and lexical decision tasks in skilled adult readers. The results showed that Vernier acuity was significantly correlated with performance in character form-matching but not visual symbol form-matching, while no correlation was found between grating acuity and character processing. Interestingly, we found no correlation of the two visual skills with lexical decision performance. These findings provide for the first time empirical evidence that the finer visual skills, particularly as reflected in Vernier acuity, may directly contribute to an early stage of hierarchical word processing.

We developed a test of English silent word reading, following work by Mather, Hammill, Allen, and Roberts (2004) and Bell, McCallum, Krik, Fuller, and McCane-Bowling (2007), in order to tap Hong Kong Chinese children``s reading of English as a foreign language. We created one subtest of individual word reading and another of word reading contextualized within sentences; together, these tests require no more than 10 minutes for administration. In Study 1, we administered the entire test to 552 second grade Hong Kong Chinese children between the ages of 70 and 121 months old, from five different primary schools. The association between the subtests of English silent word reading and contextual reading was positively correlated (.78). In Study 2, 77 Hong Kong Chinese second graders were tested on our newly developed English silent word reading test, together with non-verbal IQ, an English word reading and a Chinese character recognition test (both read aloud). With age and non-verbal IQ statistically controlled, there was a significant correlation between English silent word reading and the more standard English word reading, read aloud, (.78); the association between English silent word reading and Chinese character recognition was also positively correlated (.49). This newly created test is a quick and reliable measure, suitable for both educators and researchers to use to identify poor readers who learn English as a foreign or second language.

To examine cognitive correlates of dyslexia in Chinese and reading difficulties in English as a foreign language, a total of 14 Chinese dyslexic children (DG), 16 poor readers of English (PE), and 17 poor readers of both Chinese and English (PB) were compared to a control sample (C) of 17 children, drawn from a statistically representative sample of 177 second graders. Children were tested on pure copying of unfamiliar stimuli, rapid automatized naming (RAN), phoneme deletion, syllable deletion, and morphological awareness. With children's ages and Raven's nonverbal reasoning statistically controlled, the PE and PB groups were significantly lower than the C group on phoneme deletion and RAN tasks, while the DG performed significantly better than the PB group on the RAN task. The copying task distinguished the DG group from the C group. Findings particularly highlight the importance of phoneme awareness for word reading in English (but not Chinese), the potential need for fluency training for children with reading difficulties in both Chinese and English, and the important role that copying skills could have specifically in understanding impairment of literacy skills in Chinese (but not English).

Lexical tone is one of the most prominent features in the phonological representation of words in Chinese. However, little, if any, research to date has directly evaluated how young Chinese children’s lexical tone identification skills contribute to vocabulary acquisition and character recognition. The present study distinguished lexical tones from segmental phonological awareness and morphological awareness in order to estimate the unique contribution of lexical tone in early vocabulary acquisition and character recognition. A sample of 199 Cantonese children aged 5–6 years was assessed on measures of lexical tone identification, segmental phonological awareness, morphological awareness, nonverbal ability, vocabulary knowledge, and Chinese character recognition. It was found that lexical tone awareness and morphological awareness were both associated with vocabulary knowledge and character recognition. However, there was a significant relationship between lexical tone awareness and both vocabulary knowledge and character recognition, even after controlling for the effects of age, nonverbal ability, segmental phonological awareness and morphological awareness. These findings suggest that lexical tone is a key factor accounting for individual variance in young children’s lexical acquisition in Chinese, and that lexical tone should be considered in understanding how children learn new Chinese vocabulary words, in either oral or written forms.

Previous studies found that individuals with autism spectrum disorder (ASD) were less sensitive to the variations of lexical stress in their native language than typically developing controls. However, no study has been conducted to explore the perception of lexical stress in the second language among individuals with ASD. Using ERPs (event-related potentials) measurement with an oddball paradigm, the current study examined and compared the neural responses by Chinese-English bilingual children with ASD and typically developing controls in the processing of English lexical stress. The results showed that when compared with typically developing controls, children with ASD manifested reduced MMN (mismatch negativity) amplitude at the left temporal-parietal and parietal sites, indicating that they were less sensitive to lexical stress. However, a more negative MMN response was found for ASD group than for typically developing group at the right central-parietal, temporal-parietal, and temporal sites. In addition, the right hemisphere was more activated than the left hemisphere for ASD group, which might be derived from the reversed asymmetry of brain activation for individuals with ASD when processing language-related stimuli.

Increasing evidence suggests that children with developmental dyslexia exhibit a deficit not only at the segmental level of phonological processing but also, by extension, at the suprasegmental level. However, it remains unclear whether such a suprasegmental phonological processing deficit is due to a difficulty in processing acoustic cues of speech rhythm, such as rise time and intensity. This study set out to investigate to what extent suprasegmental phonological processing (i.e., Cantonese lexical tone perception) and rise time sensitivity could distinguish Chinese children with dyslexia from typically developing children. Sixteen children with dyslexia and 44 age-matched controls were administered a Cantonese lexical tone perception task, psychoacoustic tasks, a nonverbal reasoning ability task, and word reading and dictation tasks. Children with dyslexia performed worse than controls on Cantonese lexical tone perception, rise time, and intensity. Furthermore, Cantonese lexical tone perception appeared to be a stable indicator that distinguishes children with dyslexia from controls, even after controlling for basic auditory processing skills. These findings suggest that suprasegmental phonological processing (i.e., lexical tone perception) is a potential factor that accounts for reading difficulty in Chinese.

Using a multiple-deviant oddball paradigm, this study examined second graders’ brain responses to Cantonese speech. We aimed to address the question of whether a change in a consonant or lexical tone could be automatically detected by children. We measured auditory mismatch responses to place of articulation and voice onset time (VOT), reflecting segmental perception, as well as Cantonese lexical tones including level tone and contour tone, reflecting suprasegmental perception. The data showed that robust mismatch negativities (MMNs) were elicited by all deviants in the time window of 300–500 ms in second graders. Moreover, relative to the standard stimuli, the VOT deviant elicited a robust positive mismatch response, and the level tone deviant elicited a significant MMN in the time window of 150–300 ms. The findings suggest that Hong Kong second graders were sensitive to neural discriminations of speech sounds both at the segmental and suprasegmental levels.

In the present study, we compared models of overall writing quality, in addition to differences in grammatical usage in this writing, between children from Beijing and Hong Kong societies. Confirmatory factor analyses (CFA) resulted in a five-element scoring system used to tap overall writing quality in the Beijing sample. In addition, Beijing and Hong Kong children showed certain differences in mechanical errors in their writings. For example, Beijing children exhibited fewer errors in word order and misnomers than did Hong Kong children, but Hong Kong children performed better in punctuation usage than Beijing children. Overall, the present study highlighted some patterns in overall writing quality and also common mechanical errors in Chinese writing among Chinese children.

This study aimed to investigate the association between syntactic awareness and discourse-level reading comprehension in 136 Hong Kong Chinese children. These children, aged 11, from a longitudinal study, were administered a set of cognitive and linguistic measures. Partial correlational analyses showed that children's performances in two syntactic tasks were significantly correlated with their discourse-level reading comprehension. A multiple hierarchical regression analysis indicated that syntactic skills, especially the conjunction cloze task, accounted for unique variance in reading comprehension even when age, nonverbal IQ, phonological awareness, morphological awareness and vocabulary knowledge, as well as the auto-regressive effect of previous reading comprehension skill were statistically controlled in this study. Findings suggest that syntactic awareness is uniquely associated with discourse-level reading comprehension in Hong Kong fifth graders.

This study investigated the rate of school-aged Chinese–English language learners at risk for reading difficulties in either Chinese or English only, or both, among second and fifth graders in Hong Kong. In addition, we examined the metalinguistic skills that distinguished those who were poor in reading Chinese from those who were poor in reading English. The prevalence of poor English readers among children identified to be poor in Chinese word recognition across the five participating schools was approximately 42% at Grade 2 and 57% at Grade 5. Across grades, children who were poor readers of both languages tended to have difficulties in phonological and morphological awareness. Poor readers of English only were found to manifest significantly poorer phonological awareness, compared to those who were poor readers of Chinese only; their average tone awareness score was also lower relative to normally developing controls. Apart from indicating possible dissociations between Chinese first language (L1) word reading and English second language (L2) word reading, these findings suggested that the degree to which different metalinguistic skills are important for reading in different writing systems may depend on the linguistic features of the particular writing system.

To investigate the relationship between Chinese children's character and word reading, 62 third and 50 fifth grade children in Hong Kong were asked to read single characters and words that were comprised of these characters. Results showed that words helped children to recognize characters for both grades of children. Compared to older children, younger children's character reading was more likely to rely on the word that the character appeared in as a component; younger children made more errors in confusing the correct character with words related to it. Younger children's greater rate of meaning-related errors also underscored the role of the word in their character learning. This study confirmed the important role of words in children's character learning, and provided evidence for a developmental pattern of character and word reading in Chinese.

Because Chinese character learning typically relies heavily on rote character copying, we tested independent copying skill in third- and fourth-grade Chinese children with and without dyslexia. In total, 21 Chinese third and fourth graders with dyslexia and 33 without dyslexia (matched on age, nonverbal IQ, and mother's education level) were given tasks of copying unfamiliar print in Vietnamese, Korean, and Hebrew as well as tests of word reading and writing, morphological awareness, rapid automatized naming (RAN), and orthographic processing. All three copying tasks distinguished dyslexic children from nondyslexic children with moderate effect sizes (.67-.80). Zero-order correlations of the three copying tasks with dictation and reading ranged from .37 to .58. With age, Raven's, group status, RAN, morphological awareness, and orthographic measures statistically controlled, the copying tasks uniquely explained 6% and 3% variance in word reading and dictation, respectively. Results suggest that copying skill itself may be useful in understanding the development and impairment of literacy skills in Chinese.

Using event-related potential (ERP) measures, we examined the time course of Chinese compound word processing in 15 dyslexic and 10 normal children in a lexical decision task with three conditions including real words (e.g.,[Formula: see text] (house)), reversed nonwords (e.g.,[Formula: see text][Formula: see text] can be transposed to a real word [Formula: see text](ocean)) and random nonwords (e.g.,[Formula: see text] is not a real word when transposing). Behavioral results showed that dyslexic children performed slower and less accurately than normal children did across conditions. ERP data revealed that normal children exhibited significant N400 effects across conditions. The dyslexics did not show any difference on N400, however, suggesting a possible weakness of morphological processing in dyslexic children.
