The goal of this study was to examine the cross-lagged relations between vocabulary and word reading in children learning two scripts at the same time (pinyin and Chinese). One hundred fifty-nine third-year kindergarten Chinese children (70 girls and 89 boys; mean age = 72.70 months) were assessed on measures of nonverbal IQ, phonological…

The study used Bayesian and Frequentist methods to investigate whether the roles of linguistic, quantitative, and spatial attention skills are distinct in children's acquisition of reading and math. A sample of 175 Chinese kindergarteners was tested with measures of linguistic skills (phonological awareness and phonological memory), quantitative…

We report the validity of a test instrument that assesses the arithmetic ability of primary students by (a) describing the theoretical model of arithmetic ability assessment using Wilson's (2004) four building blocks of constructing measures and (b) providing empirical evidence for the validation study. The instrument consists of 21…

Students' understanding of the meaning of the equal sign develops slowly over the primary grades. In addition to updating their representations of equations to recognize that the equal sign represents an equivalence relation rather than signaling an operation, students need to move beyond full computation to efficiently solve equivalence problems.…

Child temperament is a predictor of non-verbal ability (i.e. thinking and problem-solving skills that do not fundamentally require verbal language production and comprehension). Given that temperament scores might vary depending on whether the reporter is a parent or a teacher, this study analyses (a) whether those reports are different and (b)…

The current study investigated perceptual simulation and its relationship with literacy ability in Chinese children. Ninety-three third-grade Hong Kong Chinese children completed a sentence-picture verification task for perceptual simulation. In this task, a sentence mentioning an object was presented first, followed by a picture involving the…

In this study, we investigated the direct and indirect associations of different cognitive-linguistic skills and Chinese reading comprehension in Hong Kong kindergarteners. We assessed 179 children's nonverbal IQ, cognitive-linguistic skills, word reading, listening comprehension, and reading comprehension. Results showed significant correlations…

Whether intended by education policy (e.g., via school entrance examinations) or unintended (e.g., via social stratification), selection effects in education (who goes where, gets what, and how much) shape educational opportunities -- influencing the life chances of individuals and groups, and the structure of societies. However, within the…

What is the foundational knowledge that children rely on to provide meaning as they construct an exact symbolic number system? People and animals can quickly and accurately distinguish small exact quantities (i.e., 1 to 3). One possibility is that children's ability to map small quantities to spoken number words supports their developing exact…

Background: Spelling is a prevalent strategy to teach children to read. However, research on the mechanism underlying the contribution of spelling to reading comprehension in Chinese children is limited. Methods: The primary aim of this study was to investigate the concurrent and longitudinal associations between spelling and reading comprehension…

Purpose: The aims of this study were to investigate the occurrence of stuttering behavior across time and to evaluate the relationship between stuttering behavior and language ability in children with Down syndrome. Method: A national age cohort of Norwegian first graders with Down syndrome (N = 75) participated in the study. Speech samples from a…

Successful integration of digital technologies in the education of young children still needs to be solved. Despite a growing body of research focusing on learning through digital technologies in childhood, there are areas of knowledge where the impact of digital technologies has yet to be explored. A prominent example is nanoscience and…

The importance of early childhood narrative skills in social relationships and children's internal capacity is of utmost interest to be studied. This aim of this study is to examine how the social group functioning, narrative skills, school success and non-verbal intelligence are interconnected. This is a mixed design study with a sample of 109…

The goal of this study was to investigate the contribution of morphological awareness to reading fluency of children with and without dyslexia in a transparent orthography, such as the Greek one. The sample consisted of 256 Greek-speaking children (2nd grade: 32 dyslexic and 105 typical readers, 5th grade: 28 dyslexic and 91 typical readers).…

Mental rotation is positively related to arithmetic ability; however, the mechanism underlying this relationship remains unclear. The possible roles of working memory, place-value concept, and number line estimation in the correlation between mental rotation and whole-number computation were investigated. One hundred and fifty-five first-grade…
