The present study investigated the executive functioning of working memory, inhibition, shifting, and planning in Chinese adolescent readers with dyslexia and how they related to Chinese (L1) and English (L2) reading comprehension. Fifty-seven Hong Kong Chinese students at Grade 7 were compared with 57 typically developing readers of chronological-age-matched controls on their performance on working memory, inhibition, shifting, planning, vocabulary knowledge, rapid naming, and reading comprehension in Chinese and English. Results from the multivariate analysis of variance showed that readers with dyslexia performed worse than the typical readers in executive functioning, vocabulary knowledge, rapid naming, and reading comprehension. Hierarchical regressions indicated that working memory, inhibition, and vocabulary knowledge were significant predictors of reading comprehension in L1 after controlling for age, IQ, and group membership. Furthermore, working memory, inhibition, shifting, vocabulary knowledge, and rapid naming contributed uniquely to reading comprehension in L2. Taken together, these findings suggest executive functioning difficulties in Chinese readers with dyslexia and highlight the differential contributions of executive functioning to Chinese and English reading comprehension; working memory and inhibition appear to play an important role in reading comprehension across different languages.

This study examined the bidirectional relationships among Chinese children's mathematics, executive functioning, and visual–spatial skills during their transition from kindergarten to primary school. Participants were 172 Cantonese-speaking Hong Kong children (mean age at Time 1 = 62.75 months; 88 male) and their parents. At Time 1 (kindergarten K3), children were administered the measures of mathematics (calculation and applied problems), executive functioning (working memory and inhibitory control), and visual–spatial skills. They were reassessed on these measures at Time 2 (primary 1) 1 year later. Results from the cross-lagged panel model showed that, controlling for child age, gender, and family socioeconomic status, children's visual–spatial skills at Time 1 were significantly predictive of their mathematics at Time 2 and children's executive functioning and visual–spatial skills reciprocally predicted each other across times. However, children's mathematics at Time 1 were not predictive of their executive functioning or visual–spatial skills at Time 2. The findings highlight the desirability of improving children's executive functioning and visual–spatial skills to promote their mathematical performance during the formal school transition.

This study examined the bidirectionality between kindergarten children's executive functioning (EF) and word reading across two time points. Participants were 523 Hong Kong Chinese-speaking children (mean age at Time 2 = 64.59 months; 52.9% male) and their parents. At Time 1, children were administered the measures of EF skills: inhibitory control, attention shifting, working memory and Chinese word reading. They were reassessed with these measures at Time 2 one year later. Results from the cross-lagged panel model revealed that, controlling for child age, gender and parental education levels, children's word reading at Time 1 was significantly predictive of their working memory at Time 2, but that the three EF skills at Time 1 were not predictive of word reading at Time 2. These findings underscored the role of early word reading in promoting children's working memory. Copyright © 2020 UKLA.

This longitudinal study investigated the bidirectional relationships between executive functioning (EF), visual skills, Chinese and English word reading abilities in children transitioning to primary school. A total of 165 children in Hong Kong were followed from the third year of kindergarten (Time 1) (mean age: 62.80 months, SD: 3.74) to the first year of primary school (Time 2) (mean age: 77.25 months, SD: 4.60). Assessments for measuring EF, visual skills, phonological awareness, morphological awareness, and Chinese and English word reading were administered to the children at the two time points. Results of cross-lagged panel analyses revealed that after age, phonological awareness, and morphological awareness were controlled, EF and visual skills exhibited a bidirectional relationship. Furthermore, EF and word reading in Chinese or English reciprocally predicted each other during the school transition period after other skills were controlled. However, visual skills and word reading in Chinese or English did not predict each other. These findings highlight the close associations between EF and visual skills as well as the importance of EF in learning to read Chinese and English in kindergarten and early primary school.
