The Influence of Perceptual Speed on Performance Versus Paper-And-Pencil Measures of Spatial Ability. Technical Report 1981-4.
Bowker, Richard; Trafton, Richard S.
The effect of perceptual speed on performance and paper-and-pencil measures of spatial ability is examined. Perceptual speed is defined as speed in comparing figures or symbols, scanning to find figures or symbols, or carrying out other very simple tasks involving visual perception. It was hypothesized that perceptual speed would have more influence on the paper-and-pencil measures because of the similarity of the tasks, and that the influence would be different for males and females. Seven hundred males and 700 females were administered a battery of tests including a measure of perceptual speed and performance measures of spatial ability from the Johnson O'Connor Research Foundation aptitude test battery, and paper-and-pencil measures of spatial ability from the Kit of Factor-Referenced Cognitive Tests. The paper-and-pencil measures had higher correlations with the measure of perceptual speed for both males and females. Factor analysis showed that inclusion of a perceptual speed factor did not affect the factor patterns for males and females, but did cause some changes in the factor loadings for females. (Author/RL)
