Similarity judgments of patterns and maps

An algorithmic technique is described for generating from a common prototype three populations of forms (dots, open forms, and polygons) having different configurational properties. Within each population, subjects rated the similarity between standard stimuli and 20 transformations of these stimuli. The stimuli were represented to the subjects as abstract patterns or as maps. High rank-order correlations were obtained between the ratings given to the various transformations in each form population and in the pattern and map conditions. These correlations led to two conclusions: (1) there was ecological validity in the stimulus factors that influenced similarity judgments in the three form populations, and (2) subjects used analogous processes when making similarity judgments in tasks focusing upon pattern perception and spatial reference systems.
