Abstract
The current study examined the executive function (EF) deficits and their roles in reading in one hundred and four Cantonese-speaking children with typical development, reading disabilities (RD), ADHD, and comorbid ADHD and RD (ADHD + RD). Children's EF and reading skills were measured. Analysis of variance results showed that all children with disorders manifested deficits in verbal and visuospatial short-term and working memory and behavioral inhibition. Moreover, children with ADHD and ADHD + RD also exhibited deficits in inhibition (IC and BI) and cognitive flexibility. These findings demonstrated that the EF deficits in Chinese children with RD, ADHD, and ADHD + RD are similar to those in their counterparts using alphabetic languages. However, children with ADHD + RD displayed more severe deficits in visuospatial working memory compared to children with RD and ADHD, which was inconsistent with that observed in children using alphabetic languages. Regression analysis results showed that verbal short-term memory was a significant predictor for both word reading and reading fluency in children with RD and ADHD + RD. Moreover, behavioral inhibition significantly predicted reading fluency in children with ADHD. These findings also agreed with previous studies. Collectively, the results of the current study showed that the EF deficits and their roles in reading found in Chinese children with RD, ADHD, and ADHD + RD are mainly consistent with children using alphabetic languages. However, more studies are still needed to confirm these findings, especially comparing the severity of working memory among these three disorders.

Abstract
This study examined (a) the identification of various reading groups across languages in Chinese (L1) adolescents learning English as a second language (ESL), in terms of their word-reading and reading comprehension skills, (b) overlap in reading group membership across languages, and (c) the performance of the various reading groups on reading-related language comprehension measures in English. The participants were 246 eighth-grade students from an English-immersion program in a middle school in China. Latent profile analysis identified three reading groups in each language: (a) a typically developing reader group with average or above-average word-reading and reading comprehension, (b) a group with poor decoding/word-reading skills and weak reading comprehension, and (c) a group with poor reading comprehension in the absence of poor decoding/word reading. The overlap in profile characteristics across languages for typically developing readers and poor decoders was high (about 68% for typically developing readers and 54% for poor decoders), whereas the overlap for being poor comprehenders in each language was moderate (about 37%). Furthermore, poor decoders in either language performed more poorly than the typically developing and poor comprehender groups on word reading in the other language, while poor comprehenders in either language performed more poorly than the typically developing and poor decoder groups on reading comprehension in the other language. The comparison of the reading groups' performance on English reading-related language comprehension measures showed that poor comprehenders and poor decoders performed worse than typically developing readers. Implications for identification and instruction of ESL children with reading difficulties are discussed.

Abstract
This study aimed to analyse the developmental trajectory of the accuracy and speed of naming among dyslexics and developing readers from 1st to 6th grade of primary education. It examined how familiarity with the stimulus influences the performance of different naming tasks in both groups and evaluated the link between naming speed and the Bangor Dyslexia Test. With a descriptive and correlational design, eight naming tasks and the Bangor Dyslexia Test (Miles, 1982; Outón & Suárez, 2010) were administered to a sample of 198 dyslexics and 245 developing readers. The results showed that the dyslexics were slower and more inaccurate in all the naming tasks, compared with the developing readers of the same age. Greater difficulty was observed with the less familiar stimuli. It became evident that naming performance improved with age among both groups of subjects. Finally, a greater number of significant and positive correlations were found between the naming tasks and the Bangor Dyslexia Test in the dyslexic group; the strongest relationship was obtained by naming letters.

Abstract
The main purpose of the present study was to investigate whether visual processing uniquely contributed to character reading and early mathematics in Chinese children. Eighty-two Chinese kindergarteners at K3 (mean age = 68 months, SD = 0.30) were followed up to grade one (mean age = 82 months, SD = 0.35) with an interval of 14 months. Nonverbal intelligence, inhibitory control, sustained attention, character reading, and mathematics were measured at kindergarten. Character reading and mathematics were assessed again at grade one. Results showed visual processing at kindergarten significantly predicted character reading at grade one after controlling for prior reading performance, inhibitory control, sustained attention, age, gender, and nonverbal IQ. Similarly, visual processing at kindergarten explained unique variance in early mathematics at grade one when prior mathematics performance and other covariates at kindergarten were controlled. These findings suggest that visual processing should serve as a domain-general precursor of children's performance in character reading and early mathematics and an important cognitive factor for later academic learning.

Abstract
Recent experimental results suggest that negation is particularly challenging for children with reading difficulties. This study looks at how young poor readers, speakers of Mandarin Chinese, comprehend affirmative and negative sentences as compared with a group of age-matched typical readers. Forty-four Chinese children were tested with a truth value judgment task. The results reveal that negative sentences were harder to process than affirmative ones, irrespective of the distinction between poor and typical readers. Moreover, poor readers performed worse than typical readers in comprehending sentences, regardless of whether they were affirmative or negative sentences. We interpret the results as (a) confirming the two-step simulation hypothesis, based on the result that the difficulty in processing negation has a general validity (persisting in pragmatically felicitous contexts), and (b) disconfirming that negation, as far as behavioral data are concerned, can be used as a reliable linguistic predictor of reading difficulties.

Abstract
Children with attention-deficit/hyperactivity disorder (ADHD) are reported to have a significantly higher risk of showing reading difficulties or disorders. Here, we aimed to identify the relationship between electroencephalographic (EEG) marker of spatial attention and reading ability in Chinese children with ADHD. First, we demonstrated that rapid automatized naming (RAN) is a strong predictor of reading ability in Chinese-speaking children. Then, EEG data of 9-to 15-year-old children with ADHD (n = 38) and typically developing (TD) controls (n = 36) were collected while the children performed a classical visual search task. Children with ADHD showed slower RAN speed than TD children. For event-related potentials (ERPs), children with ADHD showed a reduced target-evoked N2pc component, which predicted their poorer RAN performance. However, in TD children the early occipital P1 amplitude was negatively correlated with their RAN performance. The correlation between decreased N2pc and poor RAN performance in children with ADHD suggests that their reading problems may in part be due to impaired attentional selection. In contrast, in TD children, development in early visual processing co-occurs with improvements in reading ability.

Abstract
We had three aims in the present study: (1) to examine the dimensionality of various evaluative approaches to scoring writing samples (e.g., quality, productivity, and curriculum based writing [CBM]) , (2) to investigate unique language and cognitive predictors of the identified dimensions, and (3) to examine gender gap in the identified dimensions of writing. These questions were addressed using data from second and third grade students (N = 494). Data were analyzed using confirmatory factor analysis and multilevel modeling. Results showed that writing quality, productivity, and CBM scoring were dissociable constructs, but that writing quality and CBM scoring were highly related (r = .82). Language and cognitive predictors differed among the writing outcomes. Boys had lower writing scores than girls even after accounting for language, reading, attention, spelling, handwriting automaticity, and rapid automatized naming. Results are discussed in light of writing evaluation and a developmental model of writing.

Abstract
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.

Abstract
Longitudinal predictors of writing composition in Chinese and English written by the same 153 Hong Kong nine-year-old children were tested, and their production errors within the English essays across ten categories, focusing on punctuation, spelling, and grammar, were compared to errors made by ninety American nine-year-olds writing on the same topic. The correlation between quality of the compositions in Chinese and English was .53. In stepwise regression analyses examining early predictors at ages between five and nine years, tasks of speed or fluency were consistently uniquely associated with Chinese writing composition; measures of English vocabulary knowledge, word reading, or both were consistently uniquely associated with English writing quality. Compared to the American children, Chinese children's writing reflected significantly higher proportions of errors in all grammatical categories but did not differ in punctuation or spelling. Findings underscore both similarities and differences in writing at different levels across languages.

Abstract
This study examined reading performance of 102 Chinese Mandarin-speaking 4th graders in their second language (L2, English) as a function of performance in their first language (L1, Chinese). The results revealed that for Rapid Automatized Naming (RAN) and Rapid Alternating Stimulus (RAS) measures, the mean naming time decreased monotonically in high-achieving, average, and low-achieving readers. RAN and RAS differentiated poor readers from good and average readers but failed to differentiate between good and average readers. RAN deficits occurred in poor readers in both languages. Comparison of memory profiles revealed that patterns varied depending on the mode of stimulus presentation or response. Low-achieving readers performed poorly on a subtest involving visual components only and did relatively better on a subtest involving verbal components only. Poor readers in Chinese also encountered difficulties in learning English as a L2. RAN-character accounted for unique variance in two Chinese reading measures. RAN-letter explained unique variance in English mid-term reading grade. The unique variance captured by the Color Span Subtest 1 (visual-visual) was found in Chinese reading comprehension but not in English reading comprehension. Reading performance in L1 was predictive of reading performance in L2 and vice versa.

Abstract
What are the longitudinal cognitive profiles of Hong Kong Chinese children with specific reading difficulties in Chinese only, in English only, or both? A total of 16 poor readers each of Chinese (PC) and English (PE) and 8 poor readers of both orthographies (PB) were compared to a control sample (C) of 16 children; all were drawn from a statistically representative sample of 154 Hong Kong Chinese children tested at ages 5 to 9 years. PE and PB children's mothers had lower education levels than did the other groups. With children's ages and mothers' education levels statistically controlled, the PE, PC, and PB groups were significantly lower than the C group on phonological awareness. The PB and PE groups also scored significantly lower than the others on English vocabulary across years, whereas the PC and PB groups were significantly poorer than the C and PE groups on morphological awareness across years. Finally, the PB group was significantly slower than the other groups on speed naming at every age tested, underscoring the potential importance of automaticity in reading across orthographies. Findings highlight the need to consider the issue of how to identify reading difficulties in a second language.

Abstract
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.

Abstract
There were two goals of the present study. The first was to create a scoring scheme by which 9-year-old Chinese children's writing compositions could be rated to form a total score for writing quality. The second was to examine cognitive correlates of writing quality at age 9 from measures administered at ages 6-9. Age 9 writing compositions were scored using a 7-element rubric; following confirmatory factor analyses, 5 of these elements were retained to represent overall writing quality for subsequent analyses. Measures of vocabulary knowledge, Chinese word dictation, phonological awareness, speed of processing, speeded naming, and handwriting fluency at ages 6-9 were all significantly associated with the obtained overall writing quality measure even when the statistical effect of age was removed. With vocabulary knowledge, dictation skill, age, gender, and phonological awareness included in a regression equation, 35% of the variance in age 9 writing quality was explained. With the variables of speed of processing, speeded naming, and handwriting fluency additionally included as a block, 12% additional variance in the equation was explained. In addition to gender, overall unique correlates of writing quality were dictation, speed of processing, and handwriting fluency, underscoring the importance of both general automaticity and specific writing fluency for writing quality development in children.

Abstract
To clarify whether rapid naming ability itself is a main underpinning factor of rapid automatized naming tests (RAN) and how deep an influence the discrete decoding process has on reading, we performed discrete naming tasks and discrete hiragana reading tasks as well as sequential naming tasks and sequential hiragana reading tasks with 38 Japanese schoolchildren with reading difficulty. There were high correlations between both discrete and sequential hiragana reading and sentence reading, suggesting that some mechanism which automatizes hiragana reading makes sentence reading fluent. In object and color tasks, there were moderate correlations between sentence reading and sequential naming, and between sequential naming and discrete naming. But no correlation was found between reading tasks and discrete naming tasks. The influence of rapid naming ability of objects and colors upon reading seemed relatively small, and multi-item processing may work in relation to these. In contrast, in the digit naming task there was moderate correlation between sentence reading and discrete naming, while no correlation was seen between sequential naming and discrete naming. There was moderate correlation between reading tasks and sequential digit naming tasks. Digit rapid naming ability has more direct effect on reading while its effect on RAN is relatively limited. The ratio of how rapid naming ability influences RAN and reading seems to vary according to kind of the stimuli used. An assumption about components in RAN which influence reading is discussed in the context of both sequential processing and discrete naming speed.

Abstract
Logographic symbols are visually complex, and thus children's abilities for visual short-term memory (VSTM) predict their reading competence in logographic systems. In the present study, we investigated the importance of VSTM in logographic reading in adults, both behaviorally and by means of fMRI. Outside the scanner, VSTM predicted logographic Kanji reading in native Japanese adults (n=45), a finding consistent with previous observations in Japanese children. In the scanner, participants (n=15) were asked to perform a visual one-back task. For this fMRI experiment, we took advantage of the unique linguistic characteristic of the Japanese writing system, whereby syllabic Kana and logographic Kanji can share the same sound and meaning, but differ only in the complexity of their visual features. Kanji elicited greater activation than Kana in the cerebellum and two regions associated with VSTM, the lateral occipital complex and the superior intraparietal sulcus, bilaterally. The same regions elicited the highest activation during the control condition (an unfamiliar, unpronounceable script to the participants), presumably due to the increased VSTM demands for processing the control script. In addition, individual differences in VSTM performance (outside the scanner) significantly predicted blood oxygen level-dependent signal changes in the identified VSTM regions, during the Kanji and control conditions, but not during the Kana condition. VSTM appears to play an important role in reading logographic words, even in skilled adults, as evidenced at the behavioral and neural level, most likely due to the increased VSTM/visual attention demands necessary for processing complex visual features inherent in logographic symbols.
