The purpose of this analysis was to describe cognitive processes associated with comorbid difficulty between word reading (WR) and mathematics computation (MC) at the start of first grade among children selected for WR and MC delays. A sample of 234 U.S. children (mean age 6.50 years, SD = 0.31) was assessed on WR, MC, core cognitive processes…

Purpose: The purpose of this study was to examine the direct and indirect relations between short-term memory (STM), reading, oral language, and writing at the letter, word, and discourse levels in young, developing writers both cross-sectionally and longitudinally. Method: Participants were 449 English-speaking kindergarten students (52% female)…

In this study, we examined burst length and its relation with working memory, attentional control, transcription skills, discourse oral language, and writing quality, using data from English-speaking children in Grade 2 (N = 177; M[subscript age] = 7.19). Results from structural equation modeling showed that burst length was related to writing…

Proficient writing performance in English requires multiple cognitive skills, which can be particularly challenging for English Learners (ELs). However, compared with reading and mathematics, there have been fewer scientific inquiries that explore the relationship between cognitive components and writing. The purpose of this study was to examine…

Communicating their thinking in mathematics is challenging for young children. This research studied the change in six-year old students' oral and written solution explanations before and after six problem-based mathematics lessons that focused on developing conceptual understanding of adding or subtracting a 2-digit number and a multiple of ten.…

Orthographic processing -- the ability to perceive, access, differentiate, and manipulate orthographic knowledge -- is essential when learning to recognize words. Despite its critical importance in literacy acquisition, the field lacks a tool to assess this essential cognitive ability. The goal of this study was to design a computer-based…

Narrative ability comes before literacy for bilingual students and helps narrow down the gap in text-level literacy between English language learners (ELLs) and native English speakers. Kindergarten ELLs are the best age group to receive intervention to improve their oral narrative skills. Multimedia stories have potential to assist kindergarten…

In an effort to understand cognitive foundations of oral language comprehension (i.e., listening comprehension), we examined how inhibitory control, theory of mind, and comprehension monitoring are uniquely related to listening comprehension over and above vocabulary and age. A total of 156 children in kindergarten and first grade from…

Explanations of the marked individual differences in elementary school mathematical achievement and mathematical learning disability (MLD or dyscalculia) have involved domain-general factors (working memory, reasoning, processing speed, and oral language) and numerical factors that include single-digit processing efficiency and multidigit skills…

The purpose of this study was to investigate the contributions of domain-general cognitive resources and different forms of arithmetic development to individual differences in pre-algebraic knowledge. Children (n = 279, mean age = 7.59 years) were assessed on 7 domain-general cognitive resources as well as arithmetic calculations and word problems…

This study investigated the prevalence and stability of latent classes at risk for reading disabilities (RD) in elementary-aged children whose first language is Spanish. To this end, children (N = 489) in Grades 1, 2, and 3 at Wave 1 were administered a battery of reading, vocabulary, and cognitive measures (short-term memory [STM], working memory…

This study examined the overlap of dyslexia and specific language impairment (SLI) in Cantonese-Chinese-speaking children. Thirty children with a prior diagnosis of SLI and 9 normal controls, aged between 6;0 and 11;3, participated. The children with SLI were tested for language impairment and dyslexia. Seven retained a diagnosis of SLI but were…
