Joel seemed blessed with remarkable talents, but they did not reveal themselves in any obvious way in a school or class setting. Although he had been given an IQ test, his exact score could not be calculated--but it was well over 160. On a test of musical ability, Joel had attained a perfect score on all four musical attributes--a first for the…

Validity studies with the Reynolds Intellectual Ability scales (RIAS) indicated that RIAS composite intelligence index (CIX) and verbal intelligence index (VIX) scores have moderate-to-high correlation with comparable scores on other instruments. The authors of the RIAS described the VIX scale as a measure of crystallized ability and the nonverbal…

This article traces the personal as well as the intellectual and scientific relationship between Charles Darwin and his younger half-cousin Francis Galton. Although they had been on friendly terms as young men, and Darwin had in some ways been a role model for Galton, the two did not share major scientific interests until after the publication of…

The Wechsler intelligence test has four factors representing four components of intellectual function. In China, there are marked cultural, educational, and economic disparities between rural and urban dwellers, which could lead to cultural bias. The aim of this study was to apply the four-factor structure to responses to the Chinese Intelligence…

Background: Clinic and community-based epidemiological studies have shown an association between child psychopathology and language impairment. The demands on language for social and academic adjustment shift dramatically during adolescence and the ability to understand the nonliteral meaning in language represented by higher order language…

School psychologists increasingly are called on to assess academic, behavioral, and social functioning of students with autism spectrum disorders (ASDs), as well as advocate for and assist in the development, implementation, and evaluation of evidence-based instructional strategies across a wide variety of education contexts. In this study, we…

Gender differences in academic performance and achievement have been of policy concern for decades--both interest in lower performance by girls in the areas of mathematics and science and, more recently, in boys' underperformance in most other academic areas. Much previous research has focused on gender gaps, while overlooking other factors that…

Efforts to increase teacher quality have focused on increasing both the admission and graduation standards required for students entering the profession. This study examined the relationship between common standards, such as college GPA, ACT scores, and Praxis exam scores, with student teacher performance as measured by an assessment rubric based…

Writing difficulties are common among children with attention-deficit/hyperactivity disorder (ADHD), but the nature of these difficulties has not been well studied. Here we relate behavioral, psycholinguistic, cognitive (memory/executive), and graphomotor measures to spelling skills in school-age girls with ADHD (n = 30) and an age-matched group…

The present study investigated whether (a) growth patterns related to cognitive processing (working memory, updating, inhibition) differed in subgroups of children with reading disabilities (RD) and (b) growth in working memory (executive processing) predicted growth in other cognitive areas, such as reading and math. Seventy-three children (ages…

This article outlines shortcomings of currently used university admissions tests and discusses ways in which they could potentially be improved, summarizing two projects designed to enhance college and university admissions. The projects were inspired by the augmented theory of successful intelligence, according to which successful intelligence…

Traditional IQ technology, crystallized by the seminal work of Binet and Wechsler as well as others, has played a critical and profound role in psychology, making intelligence testing among the most important contributions psychology has made to society (Anastasi & Urbina, 1997). But this technology has limits; it has not had the advantage of…

Objective: It has been suggested that, as the Wechsler Adult Intelligence Scale-Third Edition (WAIS-III) and the Wechsler Intelligence Scale for Children-Third Edition (WISC-III) give a scaled score of one even if a client scores a raw score of zero, these assessments may have a hidden floor effect at low IQ levels. The study looked for…

ADHD is one of the widespread neurological disorders among children. While a substantial amount of research have addressed the issues related to assessment practices and diagnosis criteria among majority language speaking children, ADHD among bilingual children or linguistic minority children has not yet been addressed and discussed so much in the…

Inspired by a previous study of Korean deaf and hard of hearing adolescents, the researchers conducted a priming task of living-nonliving categorization with a sample of Chinese deaf and hard of hearing adolescents. The sample in this study had significantly lower accuracy levels for the thematically related items than for the taxonomically…
