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…

The Visual-Spatial Chemistry Specific (VSCS) assessment tool was developed to test students' visual-perceptual skills, which are required to form a mental image of an object. The VSCS was designed around the theoretical framework of Rochford and Archer that provides eight distinct and well-defined visual-perceptual skills with identified problems…

Measures of concrete operational thought and the Raven's Coloured Progressive Matrices were factor analyzed for a sample of primary students. Results indicated that primarily perceptual abilities are required for solution of the Piagetian tests, although abstract reasoning is involved in the solution of matrices and in conservation of substance…

Academically successful university students, after being taught effective study skills, had significantly higher approval of their teachers and gained insight into their own study habits, but did not differ significantly from a control group in semester grade point average. (MJB)

Factor analysis and multiple regression are two major approaches used to look at functional age, which takes account of the extensive variation in the rate of physiological and psychological maturation throughout life. To examine the role of racial or cultural influences on the measurement of functional age, a battery of 12 tests concentrating on…

Recognizing that photography in the classroom is highly motivating in that it offers a unique vehicle for communicating ideas visually, this study was designed to isolate variables which can be both observed and evaluated in photographs and for which instruction can be designed. Relationships among the technical and aesthetic qualities in…

This paper presents a study which investigated the relationship between field-dependence, perceptual egocentrism, and inductive reasoning in 53 kindergarten children. The general objective of the study was to assess the validity of the field-dependence measures in early childhood. Field-dependence was found to relate positively with perceptual…

The Hiskey-Nebraska Test of Learning Ability was administered to 550 deaf children and 614 hearing children. Three of the eight subtests showed different factor patterns when the results for the two groups were factor analyzed, suggesting that sensory deprivation alters the equilibrium and integration of perceputal and conceptual abilities.…

A new psychological test battery was designed to provide a much-needed comprehensive tool for assessing the perceptual and cognitive abilities of visually handicapped children in using active touch. The test materials consist of raised-line, raised-dot, raised-surface shapes and displays, and familiar and novel 3-D objects. The research used 20…

Subjects ranging from preschoolers to professors were asked to choose between pairs of stimulus pseudowords, the one most like a given target word. Unidimensional scale analysis, item analysis, and factor analysis of the data resulted in the following findings: (1) Adults showed a dominant preference to "addition" errors as opposed to errors of…

The technique of factor analysis was used to explore the structure of five batteries of readiness tests (Gates Reading Readiness Test, Developmental Tests of Visual Perception, Metropolitan Readiness Tests, Specially Constructed Readiness Test by Olson, and Wechsler Intelligence for Children) as predictor variables for the Stanford Achievement…

A total of 125 white children from three counties in Georgia (selected as representative of small rural and medium and large industrial urban populations) were administered a battery of tests in three phases of their schooling: (1) during the summer preceding their admission to the first grade, (2) near the end of the first grade, and (3) near the…
