Abstract
Matching of simultaneously presented patterns with respect to shape regardless of differences in size and orientation was investigated using reaction time methods. When a new pair of unfamiliar random polygons was presented on each trial, matching reaction times in a number of experimental conditions showed strong linear and additive effects of the linear size ratio and the angular difference in orientation between the members of a stimulus pair. However, when the same few random polygons were used over an extended number of trials, the pattern of linear and additive effects degenerated. The results provide a basis for resolving some conflicts in the literature on mental transformations of size and orientation.
