Objective: To examine the manifestation of cognitive control deficit of children with different levels of hyperactivity, an "at risk" dimension for ADHD. Method: A group of children with high hyperactivity (N = 40) and another group of children with low levels of hyperactivity (N = 38) performed a modified stop-signal anticipation task,…

Differentiation hypotheses concern changes in the structural organization of cognitive abilities that depend on the level of general intelligence (ability differentiation) or age (developmental differentiation). Part 1 of this article presents a review of the literature on ability and developmental differentiation effects in children, revealing…

This study examines the relationship between perceived stress, nonverbal cognitive functioning, and statewide academic scores in both Latinx and European American elementary students in rural school districts. A total of 44 third graders participated in the study, including 13 Latinx students and 31 European American (EA) students. Perceived…

International research suggests that early mathematical competences predicts later mathematical outcomes. In this paper, we build on our previous study of young children's mathematical competencies (MacDonald & Carmichael, 2015) to explore the relationship between mathematical competencies at 4-5 years, as measured by teacher ratings, and…

The present study explores the longitudinal development between Grade 3 word level reading skills and higher level semantic skills to Grade 10 reading comprehension for 3,157 students. In particular, this work focused on how the developmental relations varied for subsamples of students who are English learners (EL; N = 308), students identified as…

We recently proposed the Creative Reasoning Test (CRT), a test for reasoning in ill-defined problem spaces. The test asks children who first performed the Standard Progressive Matrices test (SPM) to next generate an SPM-style test item themselves. The item is scored based on different aspects of its complexity. Here we introduce a method to…

The current research was aimed mainly at exploring the reliability of a short-screening tool developed to self-evaluate visuospatial abilities in children. We presented 290 Italian third, fourth, and fifth graders with the 16-item Shortened Visuospatial questionnaire and several objective measures of intellectual efficiency, such as Raven's…

Computers have taken an increasingly prominent role in education around the world in recent years in developed and developing countries alike. As developing country governments have turned their focus from increasing enrollment to improving the quality of education in their schools, many have made access to computers a key component to their…

Preschool parent interventions may produce downstream benefits if initial intervention gains are sustained and improve later socialization experiences. This study explored associations between initial effects of the REDI (Research-based Developmentally Informed) Parent program and later benefits. A randomized trial involving 200 Head Start…

The study was implemented in the Title I Marinette School District using a randomized experimental design and parallel quasi experimental design spanning three grades 1-3 in 3 district elementary schools. The Remediation Plus Intervention is a multi-sensory, systematic synthetic phonics curriculum for all ages of students who struggle with…

This article presents results from two studies that included ethnically and socioeconomically diverse samples totaling 4,462 children in kindergarten through third grade. Each study examined the psychometric properties of a web-based, self-administered battery of assessments of socialemotional comprehension called "SELweb." Assessment…

Working Memory (WM) has a central role in learning. It is suggested to be malleable and is considered necessary for several aspects of mathematical functioning. This study investigated whether work with an interactive computerised working memory training programme at school could affect the mathematical performance of young children. Fifty-seven…

This study examined the accuracy of three shortened measures of intelligence: the Woodcock-Johnson Tests of Cognitive Ability, Third Edition Brief Intellectual Ability (WJ III COG BIA) score; the Stanford-Binet Intelligence Scale, Fifth Edition Abbreviated IQ (SB5 ABIQ); and the Kaufman Brief Intelligence Test IQ Composite (K-BIT) in predicting…

The educational community is discussing response-to-intervention (RTI) as an alternative assessment method. This study investigates assessment elements (beginning text level, ending text level, and number of weeks' participation) of the Reading Recovery (RR) program as part of a future RTI model. By means of a discriminant function analysis, third…

This report summarizes Austin Independent School District's prekindergarten student data from 2001-2002 (half-day and full-day programs) and 2007-2008 (full-day program only), including student demographics, academic performance, and attendance.
