This study examines the Wheatley Cube as a measure of spatial/visualization ability. The Wheatley Cube is a computer managed task which requires the subject to visualize a three-dimensional workspace and to find an invisible dot located within this space. Thirty-three undergraduate students were administered four tests of spatial/imaginal ability and the scores were correlated with performance measures on the Wheatley Cube task. Significant correlations were observed after subjects had adapted to the Cube Task. A second experiment extending the number of trials on the cube and employing three different spatial tests produced inconsistent results. Modifications of the Wheatley Cube procedure are discussed and specific suggestions for future validity studies are offered. (Author)
