Masked priming studies have shown that readers decompose morphologically complex words ("read+er"). Interindividual differences have been suggested to affect this phenomenon. However, its development is poorly understood. We addressed this issue by taking a longitudinal approach that allows greater rigor in establishing the relationship…

Children start preschool with large individual differences in their early numerical abilities. Little is known about the importance of heterogeneous patterns that exist within these individual differences. A person-centered analytic approach might be helpful to unravel these patterns and the cognitive and environmental factors that are associated…

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…

The present five-year longitudinal study from preschool to grade 3 examined the developmental associations among oral language comprehension, task orientation, reading precursors, and reading fluency, as well as their role in predicting grade 3 reading comprehension. Ninety Finnish-speaking students participated in the study. The students' oral…

The present longitudinal study examined the cross-lagged relations between parental causal attributions of children's math success to children's ability, parental help, children's math performance and task persistence. A total of 735 children, their mothers, fathers and teachers were assessed twice--at the end of the second and the third grades.…

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…

The authors investigated the performance on simple multiplication and division problems of 8-year-old children longitudinally to determine the developmental trajectories of both operations. Twice a year, during 2 consecutive school years, children performed a multiplication and division verification task and a number-matching task. All effects…

We report the results of a 2-year longitudinal comparison of grade 3 and grade 4 English-as-a-second-language learners in an experimental, comprehension-based program and those in a regular (i.e., more typical) language learning program. The goal was to examine the extent to which sustained, long-term comprehension practice in both listening and…
