The contribution of the three core components of working memory (WM) to the development of mathematical skills in young children is poorly understood. The relation between specific WM components and Numerical Operations, which emphasize computation and fact retrieval, and Mathematical Reasoning, which emphasizes verbal problem solving abilities in…

The present study investigated responsiveness to intervention in children with an earlier versus later diagnosis of dyslexia. We examined differences between second (n=122; early diagnosis) and third (n=158; late diagnosis) graders with dyslexia on reading and spelling abilities before, during and after a dyslexia intervention as well as in…

This study examined whether visual-spatial attention could predict Chinese reading achievement longitudinally beyond some well-established reading precursors. A total of 257 second- and third-grade Hong Kong Chinese-speaking children participated in the study. Visual-spatial attention was measured by visual search tasks, which assessed the skills…

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,…

Math achievement is an important predictor of progression to later science, technology, engineering, and math (STEM) education and careers. However, attitudinal factors also play a role, and interventions attempting to improve math attitudes may be important for increasing the number of STEM-aspiring students. To design effective interventions, it…

This study investigated the stability of latent classes of students with learning disabilities among a heterogeneous sample of elementary-aged children whose first language is Spanish. To this end, children (N = 284) in Grades 1, 2, and 3 at Wave 1 (Year 1) were administered a battery of vocabulary, reading, math, and cognitive measures…

This is a study of early picture book comprehension, its determinants and later development through primary school. More specifically, picture book comprehension was analyzed longitudinally from age 5 to age 9, delineating the unique contributions of vocabulary, metacognitive knowledge and task orientation to the initial level as well as to the…

While preschool-aged children display some skills with quantitative relations, later learning of related fraction concepts is difficult for many students. We present two studies that investigate young children's tendency of Spontaneous Focusing On quantitative Relations (SFOR), which may help explain individual differences in the development of…

We examined the role of executive attention, which encompasses the common aspects of executive function and executive working memory, in children's acquisition of two aspects of mathematical skill: (a) knowledge of the number system (e.g., place value) and of arithmetic procedures (e.g., multi-digit addition) and (b) arithmetic fluency (i.e.,…

The developmental trajectory of the use of morphemes is still unclear. We investigated the emergence of morphological effects on visual word recognition in German in a large sample across the complete course of reading acquisition in elementary school. To this end, we analyzed lexical decision data on a total of 1,152 words and pseudowords from a…

The purpose of this cohort sequential study was to extend previously reported latent transition analyses conducted by Swanson, Kudo, and Guzman-Orth (2016) by determining the role of cognitive measures in identifying English learners (EL) at risk for late emerging reading disabilities (LERD). To this end, EL students (N = 450) in Grades 1, 2, and…

The present longitudinal study tested the roles of early childhood executive control (EC) as well as exposure to poverty-related adversity at family and school levels as key predictors of low-income children's EC in elementary school ("n" = 391). Findings suggest that children's EC difficulties in preschool and lower family income from…

The relations of education, authoritarian child-rearing attitudes, and endorsement of corporal punishment to Filipino parents' reported use of corporal punishment were examined using two waves of data. Structured interviews using self-report questionnaires were conducted with 117 mothers and 98 fathers from 120 families when their children were 8…

The purpose of this study was twofold: (a) to examine the effect of task-focused behaviour on reading fluency, spelling and comprehension; and (b) to examine the role of the different literacy skills in subsequent task-focused behaviour. Two hundred and seven Finnish-speaking children were followed from preschool until their fourth year at school…

Arithmetic abilities acquired in kindergarten are found to be strong predictors for later deficient arithmetic abilities. This longitudinal study (N = 684) was designed to examine if it was possible to predict the level of children's arithmetic abilities in first and second grade from their performance on preparatory arithmetic abilities in…
