Progress in applied neuroscience and neuropsychology in the educational context has revealed efficient methodologies for preventing academic failure and developing the potential of students. The aim of this work is to adopt a neuropsychological perspective to study learning-related differences between students with learning difficulties (LD),…

The development of the Visual-Perceptual Chemistry Specific (VPCS) assessment tool is based on items that align to eight visual-perceptual skills considered as needed by chemistry students. This tool includes a comprehensive range of visual operations and presents items within a chemistry context without requiring content knowledge to solve…

Background: Very little is known about the neuropsychological correlates of adaptive functioning in people with intellectual disabilities (ID). This study examined whether specific cognitive deficits and demographic variables predicted everyday functioning in adults with ID. Method: People with ID (n = 101; ages 19-41 years; mean education = 11…

The factor-referenced kits developed by the Educational Testing Service (ETS) are assessed. With support from the National Science Foundation, the researcher surveyed the total range of research done over the past 65 years on the identification of cognitive abilities, principally through factor analysis. From a corpus of an estimated 2,000 data…

Twenty variables comprising the subtests of the Frostig, Illinois Test of Psycholinguistic Ability, Appalachia Preschool Test and the Peabody Picture Vocabulary Test raw score were factor analyzed by a principal component solution and an orthogonal rotation of the factor matrix. Although the different subtests were designed to measure specific…

A 3-factor solution of the Wechsler Adult Intelligence Scale--Revised (WAIS-R) in 260 adults with suspected head injury suggested relatively good construct validity for the factors, based on correlations with neuropsychological tests. Findings are discussed in terms of the multidimensional nature of neuropsychological tests and WAIS-R factors.…

The project's purpose was to determine whether attention to the task during testing was a confounding variable in measures of visual perception ability. Samples of 30 perceptually handicapped (PH) and 30 normal subjects (N) were randomly selected from children so classified on the Frostig DTVP, providing they had IQ scores between 85 and 115 on…

This report is part of a general study of Reference Measures for Cognitive and Noncognitive Factors. The main activity being reported is the development of "factor-referenced" or "marker" tests for several recently identified cognitive factors. A secondary activity involves the study of possible relationships to factors already…

Elementary and middle school children (n=105) completed measures of reading achievement and cognitive abilities. Factor analysis produced three empirically and theoretically derived factors, auditory processing, visual processing/speed, and memory. Together the three factors combined predicted 61 to 85% of the variance associated with different…
