We investigated the extent to which the observed gender differences in mental rotation ability among the 2,468 freshmen studying engineering at a Midwest public university attributed to the gender bias of a test. The Revised Purdue Spatial Visualization Tests: Visualization of Rotations (Revised PSVT:R) is a spatial test frequently used to measure…

Despite the pervasiveness of perception and considerable impact of perception on the use of ICT for educational purposes, there is a surprising paucity of perception assessment instruments. The present proposal expands on this through the development and initial validation of the Game Perception Scale (GPS). Based on perception literature,…

A large part of the empirical research in the field of visual attention has focused on various concrete paradigms. However, as yet, there has been no clear demonstration of whether or not these paradigms are indeed measuring the same underlying construct. We collected a very large data set (nearly 1.3 million trials) to address this question. We…

The development of executive functions in the preschool years is not fully understood. Although there exists a large body of research investigating the maturation of executive functioning in school-aged children, little is known about the emergence of such skills, in particular inhibition, among preschool-aged children. Understanding developmental…

Working under classical test theory (CTT) and item response theory (IRT) frameworks, this study investigated psychometric properties of the Revised Purdue Spatial Visualization Tests: Visualization of Rotations (Revised PSVT:R). The original version, the PSVT:R was designed by Guay (1976) to measure spatial visualization ability in…

A scheme, using features in a cartoon-like human face to represent variables, is tested as to its ability to graphically depict multivariate data. A factor analysis of Harman's "24 Psychological Tests" was performed and yielded four orthogonal factors. Nose width represented the loading on Factor 1; eye size on Factor 2; curve of mouth…

This article describes a visual assessment procedure (VAP) which evaluates capacity, attention, and processing (CAP) of infants and preschool children with visual impairments. The two-level battery considers, first, visual capacity and basic visual attention and, second, visual perceptual and cognitive abilities. A theoretical analysis of the…

Investigates extent to which perceptual factors of speed and flexibility of closure represent more general processes also operating in cognitive and personality domains by including in a single factor analysis perceptual tests and new tests requiring cognitive abilities resembling closure abilities operating in the perceptual domain.

The interdistances between thirteen places situated in different parts of the world were estimated by 60 subjects. The estimates were analysed by Kruskal's multidimensional technique and, after a cosine transformation, by factor analysis. (Author)

A Wherry-Wherry hierarchical factor analysis was performed on the Wechsler Preschool and Primary Scale of Intelligence (WPPSI) subtest intercorrelations for each of six age groups. A hierarchical arrangement of abilities highly congruent with Vernon's structure of intellect theory was obtained. The findings support the construct validity of the…

Nonmetric Multidimensional Scaling (NMDS) is a measurement technique for identifying substitute and unique leisure activities in that it allows the investigator to determine the perceptual dimensions that individuals use to organize their view of leisure activities. (MB)

The Picture Interpretation Test (Torrance and Grossman, 1967) was used in a battery of creative tests as part of a construct validity test. The test was administered to 46 boys and 37 girls in five first grade classrooms in a Clayton County, Georgia, elementary school. The purpose of the test was to measure the child's ability to "read a…

Relationships between intelligence test scores and measures derived from reaction time and perceptual speed procedures were investigated. Only three reaction time measures produced correlations greater than .25 with a general intelligence factor. Test-retest reliability of reaction time measures was low. The reaction time-intelligence relationship…

Evaluation of the Frostig Developmental Test of Visual Perception found that it measured a single general factor of perceptual organization which was weakly related to IQ and unrelated to reading ability. (KW)
