Understanding of the complement principle has been proposed as closely related to computational skills, but few studies have investigated their interrelations. The present longitudinal study attempted to clarify the picture by examining their potential cross-lagged relation. Fourth graders (n = 221) in Hong Kong received 3 cognitive assessments at…

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…

This study examined the independent contribution of morphological awareness and orthographic awareness in reading comprehension, controlling for working memory and reading fluency in Arabic-speaking children. Participants (N = 244) from grades four and five, were classified into typical comprehenders (n = 207) and poor comprehenders (n = 37). All…

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.…

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…

Children's idiom comprehension is an important aspect of language development. Idioms have both literal and figurative meanings, and there are often great differences between literal meaning and figurative meaning, which brings great difficulties to children's accurate understanding of idioms. As a kind of underlying language ability,…

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…

This study investigates school-age children's arithmetic operations performance while solving larger-size problems which produces interferences in memory. Complex problems can trigger competing responses in working memory, which are irrelevant to a task goal and increase the likelihood of interference from previously learned problems (De Visscher…

The purpose of the present research was to comprehensively assess the language abilities of Russian primary-school-aged children with Autism Spectrum Disorder (ASD), varying in non-verbal IQ, at all linguistic levels (phonology, lexicon, morphosyntax, and discourse) in production and comprehension. Yet, the influence of such non-language factors…

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…

Background: This study examined the developmental relationship between Chinese children's compounding awareness and vocabulary knowledge following a 4-year longitudinal design. Methods: A test battery that included measures of vocabulary knowledge, compounding awareness, nonverbal IQ, phonological awareness, rapid automatized naming, orthographic…
