The aim of this study was to analyze the joint, relative, and unique predictive value of students' prior knowledge of mathematics (knowledge of fractions and ability to divide natural numbers) and general cognitive ability (fluid intelligence and working memory) upon general mathematics achievement in the last year of primary school. Seventy-five…

This study explores how kindergarten students from a multilingual sample (n=131) representing 23 different languages differ in response to intervention, based on their skill in mathematics and domain general cognitive skills. Analyses for this study indicate significant correlations between initial math skill, phonological memory, working memory,…

Children are on a quest for knowledge. To achieve it, children must integrate separate but related episodes of learning. The theoretical model of memory integration posits that the process is supported by component cognitive abilities. In turn, memory integration predicts accumulation of a knowledge base. We tested this model in two studies (data…

This study examined autonomic profiles in preschoolers (N = 278, age = 4.7 years) and their relations to self-regulation outcomes concurrently and one year later, in kindergarten. Children's sympathetic (preejection period [PEP]) and parasympathetic activity (respiratory sinus arrythmia [RSA]) were measured at rest and during cognitive and…

Of all elementary school years, absenteeism is at its peak during kindergarten. Although much has been established about the effects of missing kindergarten school days on achievement, nothing has yet been established on absenteeism and executive function (EF) skills. Yet developing EF skills early in school is critical, and missed in-school time…

Working memory is an often studied and important psychological construct. The growth of working memory capacity (WMC) in childhood is described as linear. Average adult WMC is estimated as either four or five "chunks." Using latent curve models of data from a measure of digit span backward that was administered longitudinally to a large…

Background: Executive function (EF) plays a crucial role in children's reading. However, previous studies were based on offline products of reading comprehension. Online research is needed to reveal the core mechanisms underlying children's reading processing. By measuring children's working memory (WM) and cognitive flexibility (CF), we…

This study investigated the impact of soundfield amplification (SFA) on reading fluency in normal-hearing students (n = 84) aged 8-10 years. Twenty-three grade 3 and 4 classes participated across three academic terms, alternating between SFA-On and SFA-Off conditions. Reading fluency was assessed using the Wheldall Assessment of Reading Passages.…

Intelligence, as well as working memory and attention, affect the acquisition of mathematical competencies. This paper aimed to examine the influence of working memory and attention when taking different mathematical skills into account as a function of children's intellectual ability. Overall, intelligence, working memory, attention and numerical…

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…

General cognitive and specific number abilities that underlay arithmetic performance have been heavily investigated among typically developing students; however, the inquiry has rarely been applied to students with mild intellectual disability (MID). We examined whether domain-general cognitive abilities (i.e. working memory, processing speed, and…

Socioeconomic status (SES)-related language gaps are known to widen throughout the course of the school years; however, not all children from lower SES homes perform worse than their higher SES peers on measures of language. The current study uses mediation and moderated mediation to examine how cognitive and language abilities (vocabulary,…

Higher schooling attainment is associated with better cognitive function at older ages, but it remains unclear whether the relationship is causal. We estimate causal effects of schooling on performances on the Consortium to Establish a Registry for Alzheimer's Disease (CERAD) word-recall (memory) test at older ages in China, Ghana, India, Mexico,…
