This study evaluates the effectiveness of the "Parent-child Brain Camp," a 4-week video-based executive functions (EFs) training program for children ages 5-6, through a randomized controlled trial with a pre- and post-test design with 173 Hong Kong children (intervention "ni" = 79, 48.7% girls, M[subscript age] = 69.16 months;…

This study examined the direct and indirect relationships between playfulness (social and cognitive spontaneity), executive functions, convergent thinking, divergent thinking, and academic skills in Hong Kong Chinese kindergarten children. Participants were 181 second-year (4 to 5 years) kindergarten children (45.9% boys) and their parents.…

Reading comprehension difficulties exhibited by children with autism are related to executive function (EF) and theory of mind (ToM) deficits. However, the potential heterogeneity of ToM, EF, and reading comprehension abilities, and their interrelationships, among Chinese children with autism remains unclear. Using comprehensive sets of ToM and EF…

Robust relation has been revealed previously between the components of executive function (EF) and reading comprehension performance. However, the specific role of EF in the reading processes remains relatively underexplored. Within the framework of the lexical quality hypothesis (LQH), this study examined the contribution of EF to the lexical…

This study examined the cognitive predictors and constraints of children's strategic offers in the Ultimatum Game. The Ultimatum Game is a one-shot negotiation on the division of a given sum of rewards between two people, where the receiver has the right to punish the proposer by rejecting unfair offers, which results in nil reward for either…

Integrated writing (i.e., writing from sources) being a complex process, requires various linguistic and cognitive skills interacting with each other in a dynamic way. While recent studies have increasingly documented that writing processes are driven by a suite of cognitive abilities named executive function (EF), their roles in a literacy…

The present study aimed to examine the potential importance of orthographic flexibility for Chinese reading acquisition. Orthographic flexibility is a novel concept that represents the ability to manage and switch attention among multiple aspects of orthographic information. A total of 92 Chinese kindergarten children at age 6 were assessed on…

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…

The number of Chinese children living in poverty has risen steadily in Hong Kong, China. However, little is known on the longitudinal effects of family socioeconomic status (SES) on cognitive-linguistic skills, word reading and writing in children from low-SES backgrounds. This study examines differences in cognitive-linguistic skills and word…

The present study aims to examine the contribution of cognitive flexibility to metalinguistic skills and reading comprehension during primary school years. Forty-nine third-grade primary school children completed the measures of cognitive flexibility, metalinguistic skills including syntactic awareness (word order knowledge), morphosyntactic skill…

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…

Previous research findings indicate that young children from East Asia outperform their counterparts from Europe and North America on executive function (EF) tasks. However, very few cross-national studies have focused on EF development during middle childhood. The current study assessed the EF performance of 170 children in grades 2 and 4 from…

Drawing on Geary's (1995) evolution-based model of cognitive and academic development, this study investigated the relation between biologically primary skills (vocabulary, executive functions, and visual-spatial processing) and subsequent word reading and calculation. It also examined the extent to which these relations were mediated by…

Purpose: This study aims to investigate the relationship between nonverbal cognitive functions and language processing of people with aphasia (PWA) by taking a data-driven approach, as well as multiple cognitive components and multilevel linguistic perspectives. It is hypothesized that language performance is differentially associated with…

This cross-sectional study examined the associations of visuomotor integration and executive functioning with Chinese word reading and writing in kindergarten children. A total of 369 Chinese children (mean age = 57.99 months; 55% of them were girls) from Hong Kong, China, completed tasks on visuomotor integration, executive functioning, and…
