The construct validity of the International Cognitive Ability Resource (ICAR) has yet to be investigated using a gold-standard individually administered intelligence battery. The present study used a convenience sample of 97 students to examine the respective relations between the ICAR16 and overall intelligence (g) and the Cattell-Horn-Carroll…

This study aimed to investigate the psychometric properties of the Wechsler-4 Intelligence Scale who are deaf with Mild Intellectual Disability. Descriptive survey method was used. The sample included (174) deaf students in Jordan, ranging in age from (6-16.11) years. The scale was also applied in sign language. Validity indicators were found…

An accurate assessment of cognitive abilities in populations that differ from the majority in cultural and linguistic characteristics is one of the main challenges in cognitive testing. Previously developed methods for assessment of the validity of cognitive scores in individuals with diverse backgrounds, such as the Culture-Language…

U.S. Supreme Court justices and other federal judges are, effectively, appointed for life, with no built-in check on their cognitive functioning as they approach old age. There is about a century of research on aging and intelligence that shows the vulnerability of processing speed, fluid reasoning, visual-spatial processing, and working memory to…

An adapted version of the Wechsler Preschool and Primary Scale of Intelligence--Third Edition (WPPSI-III) was administered to assess cognitive functioning among 1,253 5-year-old children from the Malnutrition and Enteric Disease (MAL-ED) study--an international, multisite study investigating multiple aspects of child development. In this study,…

Background: Current UK measures of early spoken language comprehension require manipulation of toys and/or verbal responses and are not accessible to children with severe motor impairments. The Computer-Based Instrument for Low motor Language Testing (C-BiLLT) (originally validated in Dutch) is a computerized test of spoken language comprehension…

Assessing higher-level verbal repertoires of individuals with autism and related intellectual disabilities is crucial due to the language and cognitive deficits experienced by this population as well as is the need for valid assessment tools for data-driven and individualized treatment. In addition to, curricula or instructional protocols that…

Research on high-ability postsecondary students has increased in recent years; yet identifying such students can be challenging. The International Cognitive Ability Resource (ICAR) is an online, open-access tool designed to facilitate measurement of cognitive abilities in research. We evaluated whether the ICAR is appropriate to identify…

Magnet schools have been a main tool or innovation in urban education settings in the United States, originating in the early 1970's and expanding into most large urban districts today (Blank, 1989). While some magnet schools do not rely on a specific criterion to determine entry, many do. This study focuses on such a setting where students must…

The aim of this study was to assess evidence for the validity of General Mindset (GM) and Engineering Mindset (EM) surveys that we developed for fifth-grade students (ages 10-11). In both surveys, we used six items to measure student mindset to determine if it was more fixed (presuming intelligence is fixed and failure is a sign that one is not…

The paper is focused on the investigation of impact of created experimental natural scientific programme for preschool-age children. Our programme concentrates on physics teaching adapted for preschool age in which children have possibilities to make experiments themselves--empirical cognition. Its innovation with respect to other stimulation…

Objective: The Wechsler Preschool and Primary Scale of Intelligence -- Fourth Edition Australian and New Zealand Standardised Edition (WPPSI-IV[superscript A&NZ]) is one of the most widely used intelligence assessments for children aged 2 years 6 months to 7 years 7 months. Given the impact of clinical and placement decisions that are…

Each year many students take college admissions exams (i.e., SAT® and ACT®), hoping to demonstrate their ability to perform at a collegiate level and gain admission to desired universities. However, a growing movement encourages colleges and universities to abandon this practice in their admissions protocol and instead consider alternative…

Current taxonomies of intelligence comprise two factors of mental speed, clerical speed (Gs), and elementary cognitive speed (Gt). Both originated from different research traditions and are conceptualized as dissociable constructs in current taxonomies. However, previous research suggests that tasks of one category can be transferred into the…

In this commentary, we reviewed two clinical validation studies on the Wechsler Scales conducted by Weiss and colleagues. These researchers used a rigorous within-battery model-fitting approach that demonstrated the factorial invariance of the Wechsler Intelligence Scale for Children-Fourth Edition (WISC-IV) and Wechsler Adult Intelligence…
