By the end of primary school, children are expected to acquire a range of mathematical skills that progressively develop. This study aimed to gain insight into how a large number of numerical and geometrical measures are grouped and whether the structures shift or remain invariant along child's development based on the data obtained from a sample…

The aim of this study is to investigate whether maternal spatial support during two types of joint manipulative toy play tasks with 2-year-old children was longitudinally associated with math screening test scores in second grade. The interaction between spatial support and maternal education was explored as well. We also investigated predictions…

The purpose of this study was to explore the possible causes that might contribute to the disproportionate percentage of English language learners ELLs with special education individual education plans (IEPs). Elementary school classroom teachers from school districts that exhibited high growth in the percentage of ELLs with IEPs during 2007-2010…

Investigates multiple trends in perceptual development of kindergarten, second grade, and fifth grade children who performed a speeded card sorting task with spatially integrated versus spatially separated dimensions. Results strongly support the hypothesis that there are developmental differences in perceived structure as well as ability to…

Tests the hypothesis that habituation of attention to irrelevant information can account for within-task improvement in selective attention--that children who are preexposed to stimuli that will later be irrelevant in a speeded classification task will experience less interference than children not given the opportunity to habituate. (HOD)

Children's memory for spatial locations in a room designed to look like a grocery store was examined. In the first of two studies, 48 preschoolers completed a memory task for spatial locations problem and an incidental recall task in two room arrangements varying in logical organization. Memory for spatial locations was higher in a clustered and…

Children as young as five years of age responded faster in a categorical task when information was initially presented to the left hemisphere, and faster in a coordinate task when information was initially presented to the right hemisphere. This finding provided evidence for the existence of distinct subsystems that compute categorial and…
