Spatial ability has long been regarded as important in STEM, and mental rotation, a subcategory of spatial ability, is widely accepted as the cognitive ability with the largest gender difference in favor of men. Multiple meta-analyses of various tests of spatial ability have found large gender differences in outcomes of the mental rotation test…

Measurement of mental rotation presents a serious challenge to cognitive researchers owing to the lack of a single comprehensive measure that can be applied across the developing age groups. Objective of the present study was to develop and validate a new measure of mental rotation for preadolescent and adolescent age groups. Items were…

The word "test" comes to mind when a person, who is unacquainted with education discourses, reads about assessment issues. Beyond issues of reliability and validity in designing measurement constructs, assessment for school geography must result in better geographical learning. In other words, there must be "consequential…

The authors' purpose was to investigate the effect of origami-based instruction on elementary students' spatial ability. The students' self-reported perceptions related to the origami-based instruction were also examined. Data was collected via purposive sampling techniques from students enrolled in a private elementary school. A spatial ability…

In autism spectrum disorders, results of cognitive testing inform clinical care, theories of neurodevelopment, and research design. The Wechsler Intelligence Scale for Children and the Stanford-Binet are commonly used in autism spectrum disorder evaluations and scores from these tests have been shown to be highly correlated in typically developing…

The Wechsler Abbreviated Scale of Intelligence, Second Edition (WASI-II; Wechsler, 2011), published by Pearson, is a newly updated abbreviated measure of cognitive intelligence designed for individuals 6 to 90 years of age. Primarily used in clinical, psychoeducational, and research settings, the WASI-II was developed to quickly and accurately…

The construct of spatial ability is discussed and it is suggested that some widely used and cited tests that are called spatial ability tests may not be valid measures of that ability. Instead, their items may be solved using mental processes that are clearly analytical and not spatial in nature. Four studies involving the analysis of subjects'…

This report presents the results of a study designed to evaluate the Johnson O'Connor Research Foundation's (JOCRF's) measurement of structural visualization. Three experimental tests--the Incomplete Open Cubes Test, the Guilford-Zimmerman Spatial Visualization Test, and Raven's Advanced Progressive Matrices--were added to the JOCRF's test battery…

Several measures of the speed of information processing were related to ability factors derived from the Cattell-Horn theory of fluid and crystallized intelligence. Correlations among the ability measures, among the information processing measures, and between the two domains were analyzed using confirmatory factor analysis. (Author/PN)

The validity and reliability of a novel route learning test were examined to assess the effectiveness of its use in evaluating spatial memory in healthy older adults and patients with Alzheimer's disease (AD). The Puget Sound Route Learning Test was significantly correlated with an existing measure of cognitive ability, the Dementia Rating Scale.…

This kit contains materials necessary to administer the Cognitive Assessment System (CAS), an assessment battery designed to evaluate cognitive processing in children 5 through 17 years of age. Derived from the Planning, Attention, Simultaneous, and Successive (PASS) theory, the four processing areas comprise the four scales that make up the CAS.…
