A Structural Theory of Spatial Abilities.

Peer reviewed

Guttman, Ruth; And Others – Applied Psychological Measurement, 1990

After a brief review of the contributions of factor analysis and regional analysis to the elaboration of the structures of spatial abilities, a facet design and regional model for spatial abilities are presented. A cylindrical-wedge model is proposed to represent the correlational structure of spatial ability tests. (SLD)

A Generative Analysis of a Three-Dimensional Spatial Task.

Peer reviewed

Bejar, Isaac I. – Applied Psychological Measurement, 1990

The feasibility of modeling performance on a three-dimensional rotation task within the context of item response theory was examined using 160 high school students. Eighty pairs of three-dimensional Shepard-Metzler figures were used. This approach to psychometric modeling, incorporating research results from cognitive science, appears workable.…
