知覚の階層性に依存する複合図形と充填図形の良さと複雑さ

抄録

Two experiments on goodness and complexity for dot patterns were performed, using a within-participant design, regarding the contrast polarity of open and solid circles. The results supported the three-stage model of pattern perception by Hamada et al. (2011b), as follows. The patterns used were invariant under the transformations of rotation and reflection, forming cyclic (C_n) or dihedral (D_n) groups (n=1, 2, 3, 4). Goodness of all dot patterns and simplicity of compound patterns increased separately as functions of the orders of C_n and D_n groups, revealing processing at the third structural description stage. The complexity of filled patterns with collinear elements, which consisted of three solid circles, depended identically upon the orders of Cn and Dn groups, revealing that processing occurred at the second feature and structure detection stage, whereas the complexity of the open/solid reversal patterns was processed at the third stage. The complexity of noncollinear element patterns was not consistent with the symmetry groups, revealing that processing occurred at the first primary processing stage.
