Investigation on the Comparisons of Feature Locations Explain the Difficulty in Discriminating Mirror-Reflected Pairs of Geometrical Figures from Disoriented Identical Pairs | Chapter 4 | Theory and Practice of Mathematics and Computer Science Vol. 11

 The purpose of this experiment is to see if patterns of feature placement shifts can influence whether people make the same or different decisions when presented with two geometrical figures at the same time. The angular distance between the location of a feature in one figure and the position of the identical feature in another figure was characterised as a shift of locations. The difficulty in distinguishing mirror-reflected (or axisymmetric) pairs from disoriented identical pairs was thought to be due to the axisymmetric pairs' complicated changing patterns. Five pair kinds were created based on the shifts in the placements of the four structural elements. In terms of shifts, they can be sorted into four groups: identical 0/4 pairs, non-identical 1/4 pairs, non-identical 2/4 pairs, axisymmetric 2/4 pairings, and non-identical 4/4 pairs. The latencies for non-identical pairings reduced as the difference in feature location shifts increased, demonstrating that serial, self-terminating shift comparisons were used to distinguish non-identical pairs from identical pairs. The greater latencies in axisymmetric 2/4 pairs compared to non-identical 2/4 pairs revealed that the problem for axisymmetric pairings was not caused by the complicated shifting patterns, and that the difficulty could not be explained effectively by feature location comparisons. The latencies obtained for Nonid pairings reduced as the difference in feature location shifts increased, demonstrating that serial, self-terminating shift comparisons were used to distinguish Nonid pairs from Id pairs.
