Objective: The current study investigated the Wechsler Intelligence Scale for Children-Fourth Edition (WISC-IV) cluster profiles of children with ADHD to examine the association between IQ profiles and diagnostic frequency, symptomatology, and outcome in this population. Method: Hierarchical cluster analysis was conducted on 189 children with a…

Since the 1980s, stakeholders have perceived Career and Technical Education (CTE) as a dumping ground for underachieving students who will not attend a 4-year college or university. Thus, the stigma has been created that CTE only serves low-performing students. The problem addressed in this study was that students were dropping out of high school…

Reading comprehension is a highly demanding task that involves the simultaneous process of extracting and constructing meaning in which working memory's executive processes play a crucial role. In this article, a training program on working memory's executive processes to improve reading comprehension is presented and empirically tested in two…

People remember information that is important to them--because it is fundamental to their well-being, or because it matters to them in some other significant way. This is all one really needs to know about unlocking student learning. People learn and remember information that matters to them. So what matters to students? That is a complicated…

This study examined the prevalence of dyslexia and dyscalculia among persons with academic deficits in English Language and Mathematics in public primary schools in Ibadan metropolis. A correlational survey study, sampling 477 pupils who were between the ages of eight and 12 years, and in 4th and 5th grades with the use of four research…

The study explored the predictive validity of "Multiplex Empirically Guided Inventory of Ecological Aggregates for Assessing Sexually Abusive Children and Adolescents (Ages 4 to 19)" ("MEGA"[eighth note]; Miccio-Fonseca, 2006b), a comprehensive developmentally sensitive risk assessment outcome tool. "MEGA"[eighth note] assesses risk for coarse…

Background: Preschool involves an array of new social experiences that may impact the development of early externalizing behavior problems over the transition to grade school. Methods: Using longitudinal data from a nationally representative sample of over 600 pairs of US twins, we tested whether the genetic and environmental influences on…

This study compared two popular measures of cognitive ability for preschool children. The "Wechsler Preschool and Primary Scale of Intelligence-Third Edition" (WPPSI-III) and the "Stanford-Binet Intelligence Scale-Fifth Edition" (SB5) were administered in a counterbalanced order to 36 typically developing 4-year-old children.…

The Kaufman Adolescent and Adult Intelligence Test (KAIT[TM]) is an individually administered test of intelligence for individuals ranging in age from 11 to 85+ years. The item response theory-likelihood ratio procedure, based on the two-parameter logistic model, was used to detect differential item functioning (DIF) in the KAIT across males and…

The analysis of response inconsistency is a crucial aspect of intellectual and clinical psychological assessment. Erratic patterns of failures and successes across and within particular domains qualify the measurement of intellectual potential and functioning. Although the interpretation of intertest scatter (inconsistencies between subtest…

Here we reprint, and provide background and a commentary on, a recently-rediscovered lecture by Godfrey H. Thomson entitled, "Intelligence and civilisation." It was delivered at the University of Manchester, UK, on 23rd October, 1936, printed in 1937 in the short-lived "Journal of the University of Manchester" and as a pamphlet…

Elementary cognitive tasks (ECTs) are simple tasks involving basic cognitive processes for which speed of performance typically correlates with IQ. Inspection time (IT) has the strongest IQ correlations and is considered critical evidence for neural speed underlying individual differences in intelligence. However, results from Bors et al. [Bors,…

Previous studies indicated impaired magnocellular (M) and relatively spared parvocellular (P) visual pathway functioning in patients with fragile X syndrome. In this study, we assessed M and P pathways in 22 female fragile X premutation carriers with normal intelligence and in 20 healthy non-carrier controls. Testing procedure included visual…

The aim of this article was to investigate the influence of a hegemonic class concept in teacher education, more specifically, the changes in the construction of implicit theories of intelligence within future teachers when they were exposed to the scientific g-factor theory of intelligence. A 2 x 2 ANOVA (first versus last semester at the teacher…

This study surveyed a national sample of school psychologists with respect to the identification of reading disabilities (RD). It covers school psychologists' opinions regarding perceived benefits of the use of cognitive assessment in RD identification, both within and outside of an IQ-achievement discrepancy model. The survey also solicited…
