Previous research findings indicate that young children from East Asia outperform their counterparts from Europe and North America on executive function (EF) tasks. However, very few cross-national studies have focused on EF development during middle childhood. The current study assessed the EF performance of 170 children in grades 2 and 4 from…

Executive function (EF) contributes significantly to reading comprehension across the lifespan. Emerging research indicates domain-specific assessments of EF are better suited for assessment and intervention in academic contexts. For example, "graphophonological-semantic cognitive flexibility" (GSF), the ability to flexibly switch…

Books designed for beginning readers typically intermix text with illustrations in close proximity. Prior research suggests this standard layout may reduce literacy skills due to increased attentional competition between text and illustrations. The current study extends this work by examining whether manipulations to the book layout can enhance…

Although substantial research indicates motivation contributes significant variance to reading comprehension in upper elementary students, research with students in primary grades has focused, instead, on the relation of motivation to word reading. Assessment of reading motivation in 68 first and second graders indicated word and nonword reading…

This study examined metalinguistic awareness in children who were becoming bilingual in an immersion education program. The purpose was to determine at what point in emerging bilingualism the previously reported metalinguistic advantages appear and what types of metalinguistic tasks reveal these developmental differences. Participants were 124…

Background: The relationship between executive functions and mathematical skills has been studied extensively, but results are inconclusive, and how this relationship evolves longitudinally is largely unknown. Aim: The aim was to investigate the factor structure of executive functions in inhibition, shifting, and updating; the longitudinal…

We studied developmental trends in 5 important reasoning tasks that are critical components of the operational definition of rational thinking. The tasks measured denominator neglect, belief bias, base rate sensitivity, resistance to framing, and the tendency toward otherside thinking. In addition to age, we examined 2 other individual difference…

This investigation is an initial examination of possible enhancement of executive function through a dual-language (50:50) education model. The ethnically diverse, low-income sample of 120 children from Grades K, 2, and 4 consisted of approximately equal numbers of children enrolled in dual-language and traditional classrooms. Dual-language…
