A COMPARISON OF SYMMETRY SALIENCE IN COMPUTER VS DESIGN-EXPERT GENERATED DOT PATTERNS
To examine how spatial configuration of stimulus elements affects symmetry perception, reaction times (RTs) to dot-patterns with different spatial configurations are measured in two experiments. In the first experiment, RTs for symmetry detection were measured for a total of 640 computer-generated dot patterns with a â€˜go/no-goâ€™ task. Based on the RT data, 2 sets of 20 patterns were determined which yielded shorter and longer RTs. Inspection of the spatial configurations in these dot patterns suggested that the two sets differ with respect to â€˜continuityâ€™, â€˜closureâ€™ and other attributes of the dot elements. In the second experiment, RTs to computer-generated patterns and those generated by a design-expert are compared, to investigate additional factors contributing to perceptual salience of pattern symmetry.
