Executive functioning (EF) refers to a set of higher order, core cognitive processes that facilitate planning, problem solving, and the initiation and maintenance of goal‐directed behavior. Although recent research has established the importance of EF for word reading development in early childhood, few studies have investigated the role of EF in reading comprehension during middle childhood. This study investigated the relations between two specific dimensions of EF—attention shifting and inhibitory control—and reading comprehension for students in fourth grade (N = 120). Specifically, we used path analysis to investigate the direct, unique associations of attention shifting and inhibitory control with reading comprehension as well as the indirect associations with reading comprehension via language comprehension and word reading, controlling for working memory, processing speed, and phonological awareness. Results indicated that both attention shifting and inhibitory control demonstrated unique direct associations with reading comprehension. Attention shifting also demonstrated a significant indirect association via language comprehension. Findings support growing evidence for the importance of these EF dimensions to reading, raise questions about potential mechanisms underlying links between EF and reading comprehension, and offer implications for understanding and addressing reading comprehension difficulties.

Longitudinal associations of domain-general and numerical competencies with individual differences in children’s understanding of fractions were investigated. Children (n = 163) were assessed at 6 years of age on domain-general (nonverbal reasoning, language, attentive behavior, executive control, visual-spatial memory) and numerical (number knowledge) competencies; at 7 years on whole-number arithmetic computations and number line estimation; and at 10 years on fraction concepts. Mediation analyses controlling for general mathematics ability and general academic ability revealed that numerical and mathematical competencies were direct predictors of fraction concepts whereas domain-general competencies supported the acquisition of fraction concepts via whole-number arithmetic computations or number line estimation. Results indicate multiple pathways to fraction competence.

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 yrs) were assessed on 7 domain-general cognitive resources as well as arithmetic calculations and word problems at start of 2nd grade and on calculations, word problems, and pre-algebraic knowledge at end of 3rd grade. Multilevel path analysis, controlling for instructional effects associated with the sequence of classrooms in which students were nested across grades 2–3, indicated arithmetic calculations and word problems are foundational to pre-algebraic knowledge. Also, results revealed direct contributions of nonverbal reasoning and oral language to pre-algebraic knowledge, beyond indirect effects that are mediated via arithmetic calculations and word problems. By contrast, attentive behavior, phonological processing, and processing speed contributed to pre-algebraic knowledge only indirectly via arithmetic calculations and word problems.
