Abacus-based mental calculation (AMC) is a widely used educational tool for enhancing math learning, offering an accessible and cost-effective method for classroom implementation. Despite its universal appeal, the neurocognitive mechanisms that drive the efficacy of AMC training remain poorly understood. Notably, although abacus training relies…

Musical abilities, both in the pitch and temporal dimension, have been shown to be positively associated with phonological awareness and reading abilities in both children and adults. There is increasing evidence that the relationship between music and language relies primarily on the temporal dimension, including both meter and rhythm. It remains…

Attention is an important, multifaceted cognitive domain that includes many key cognitive processes involved in learning. This study aimed to identify the predictive links between different components of attentional skills and core calculation skills development, using two standardized measures assessing calculation (AC-MT 6-11) and attention…

We examined the developmental trajectories and cognitive predictors of first language Chinese reading, second language English reading, and mathematics skills in Hong Kong children in Grades 1-5. We used longitudinal data of 1,000 children (M[subscript age] = 7.59 years) assessed on phonological awareness, rapid naming, and morphological awareness…

This study explores reading and spelling development of Turkish-speaking children in Grade 1 and 2. We examined predictors of word spelling and reading skills as well as the developmental relationship between spelling and reading abilities. Our major focus was on the role of phonological encoding skills and rapid automatized naming (RAN) in…

This study explored the role of growth in the executive components of working memory (WM) on second language (L2) mathematical problem-solving in elementary school children who are emerging bilinguals whose first language (L1) is Spanish. To this end, children (N = 429) in Grades 1, 2, and 3 at Wave 1 were administered a battery of math, reading,…

The present study investigated the relationship between two major components of executive functioning (EF) and externalizing behavior problems (EBP) during the early elementary years. More specifically, Working Memory (WM) and Cognitive Flexibility (CF) measured in kindergarten through second grade were used to predict teacher ratings of EBP in…

Fractions are highly important. Therefore, it is crucial to understand the developmental trajectory of fraction knowledge and its main predictors and consequences. Our research team has proposed that we have a neurocognitive architecture dedicated to processing nonsymbolic ratios, which serves as a startup tool for fractions: the Ratio Processing…

Although research on cognitive correlates of spelling has been conducted, these studies generally do not distinguish between different types of targets that need to be spelled. Arguably, the contributions of these skills differ for words opposed to pseudowords and for targets that can be spelled on the basis of phoneme-to-grapheme conversion…

There is an ongoing debate over the psychophysical functions that best fit human data from numerical estimation tasks. To test whether one psychophysical function could account for data across diverse tasks, we examined 40 kindergartners, 38 first graders, 40 second graders and 40 adults' estimates using two fully crossed 2 × 2 designs, crossing…

This study evaluated a new measure for analyzing the process of children's problem solving in a series completion task. This measure focused on a process that we entitled the "Grouping of Answer Pieces" (GAP) that was employed to provide information on problem representation and restructuring. The task was conducted using an electronic…

Executive function skills have a direct link to reading comprehension (Carretti, Borella, Cornoldi, & De Beni, 2009). Specifically, cognitive flexibility and working memory have been shown as a significant contributor to reading comprehension (Cain, Oakhill, & Bryant, 2004; Cartwright, 2002). Understanding the link between cognitive…

Although research suggests that certain cognitive functions predict the likelihood of intervention response for students who receive Tier 2 instruction through a response to intervention framework, researchers know less about cognitive predictors of response to Tier 3 instruction. This study measured 2nd and 3rd graders' performance on 7 cognitive…

Purpose: Reading requires the ability to decode and comprehend. Impairments in working memory (WM) are often implicated in students who are poor decoders. It is unclear whether this is a domain-specific issue or a task-specific issue. Therefore, this study examined how auditory-verbal (AV) WM, visual-spatial (VS) WM, and cognitive load affected…

This study explored factors that are associated with calculation development among 176 children at-risk for learning difficulties. Data were collected on working memory, language, non-verbal reasoning, processing speed, decoding, numerical competence, incoming calculation, SES, and gender at the beginning of 1st grade and on calculations over 4…
