Strategic differences in spatial tasks are explained in terms of different cognitive coordinate systems that subjects adopt such as standard versus arbitrary, task-defined axes. A theoretical account of mental rotation of individuals of low and high spatial ability solving problems from psychometric tests is instantiated as computer simulation…

Two experiments with 89 college students identify the abilities distinguishing among individuals. (SLD)
