PSYCHOPHYSICS AND EXPERIMENTAL PHENOMENOLOGY OF PATTERN COGNITION

Part 1. Symmetry cognition
1. Rotational and reflectional transformations
2. Goodness and simplicity of dot patterns in a regular hexagonal grid
3. Cognitive judgments and group theoretical model for dot patterns in a square grid
4. A three-stage model with group theory and a spatial filter for cognitive judgments
5. Cognitive judgments for repetitive patterns
6. Cognitive judgments for one-dimensional black-and-white filled patterns

Part 2. Contour perception and brightness illusion
7. Mathematical models of an antagonistic process of excitation and inhibition
8. The brightness illusions and a five-level qualitative model based on the decrease in brightness levels
9. A five-level qualitative model for various aspects of brightness contrast
10. A three-level qualitative model for the Ehrenstein illusions

Part 3. Size of the circle in a geometrical illusion
11. The Ebbinghaus illusion as a circle size contrast
12. The Delboeuf illusion by comparative judgment
13. Concentric circle illusion and judgment-order effect by absolute judgments

Part 4. Negative time-order effect on weight sensation
14. Excitation and inhibition in negative time-order effect

• Examines the cognitive transformations underlying pattern cognition and the specialized subsystems for processing transformations
• Provides an interdisciplinary psychophysics and experimental phenomenology perspective
• Features sections that cover symmetry cognition, contour perception and geometric illusion
• Describes weight sensation and repetitive and dot patterns
