The Woodcock-Johnson IV Tests of Cognitive Abilities (WJ IV COG) is a comprehensive assessment battery designed to assess broad and narrow cognitive abilities, as defined by the Cattell-Horn-Carroll (CHC) theory of intelligence. Previous studies examined the invariance of the WJ assessments across sex and age groups using factor analytic methods.…

This study explores the influence of kindergarten care on the social and cognitive development of Saudi Arabian and international students in early childhood education in Saudi Arabia. A mixed-methods approach assessed the development of 302 children, aged between 5 years and 11 months to 7 years, and their mothers in Saudi Arabia's Eastern…

Conditions influencing 328 students' (Grades 6-8) preferences for collaborating or working alone on challenging projects were investigated, as well as their potential interactions with ability, grade and sex. Each student completed the Cognitive Abilities Test (Form 7) and Project Context Survey. No overall preference for individual or…

Purpose: Language production, a dynamic process involving real-time language processing, is crucial for children's language and communication development. To explore the early development of children's real-time language production, this study investigated Chinese preschool children's pausing strategies in narratives and their associations with…

The predictive utility of cognitive abilities on reading, writing, and mathematics achievement domains helps inform high-stakes decision making, such as learning disabilities. An examination of differences in specific groups may increase understanding of obtained scores on cognitive ability and academic achievement standardized tests. One…

The present study examined whether global ability influences on reading, writing, and math achievement are generalizable across gender in children and adolescents in Grades 1 to 4 (n = 1,276), 5 to 8 (n = 1,265), and 9 to 12 (n = 1,042) using multiple group structural equation modeling with the standardization samples for the Woodcock-Johnson IV.…

Neurological soft signs (NSSs), minor neurological abnormalities, have been implicated as risk factors for poor cognitive performance in small-scale studies. Here we investigate the associations between NSSs and multiple domains of cognitive performance in a large, population-based cohort and evaluate sex differences in these associations. We…

Purpose: The aims of the study were to compare the Cognitive Self-Report Questionnaire (CSRQ; Spina, Ruff, & Mahncke, 2006) Hearing and Cognitive subscale ratings among older adults with and without probable mild cognitive impairment (MCI) and to examine whether self-report, as measured by the CSRQ, is associated with objective measures of…

The two most commonly used nonverbal tests for gifted identification, the Naglieri Nonverbal Ability Test (NNAT) and the Cognitive Abilities Test (CogAT) nonverbal battery, have not been compared in their newer versions to explore the effects of their use on the identification of underserved populations. Additionally, the effects of the use of…

This paper addresses to assess the critical thinking ability of postgraduate students. The target population was the male and female students at University level in Pakistan. A small sample of 45 male and 45 female students were selected randomly from The Islamia University of Bahawalpur, Pakistan. Cornell Critical Thinking Test Series, The…

We examined children's sleep at age 9 as a predictor of developmental trajectories of cognitive performance from ages 9 to 11 years. The effects of sleep on cognition are not uniform and thus we tested race/ethnicity, socioeconomic status (SES), and sex as moderators of these associations. At the first assessment, 282 children aged 9.44 years (52%…

The purpose of this study was to investigate the relationship between cognitive flexibility, academic skills, educational trajectories, and career goals of college students with and without Attention Deficit Hyperactivity Disorder (ADHD). Participants completed a demographic questionnaire, objective and subjective measures of cognitive…

The Cattell-Horn-Carroll (CHC) model is a comprehensive model of the major dimensions of individual differences that underlie performance on cognitive tests. Studies evaluating the generality of the CHC model across test batteries, age, gender, and culture were reviewed and found to be overwhelmingly supportive. However, less research is available…

Learning preferences have been indirectly linked to student success in engineering programmes, without a significant body of research to connect learning preferences with cognitive abilities. A better understanding of the relationship between learning styles and cognitive abilities will allow educators to optimise the classroom experience for…

A central goal of science education is to help students to develop their higher order thinking skills to enable them to face the challenges of daily life. Enhancing students' higher order thinking skills is the main goal of the Kurdish Science Curriculum in the Iraqi-Kurdistan region. This study aimed at assessing 7th grade students' higher order…
