Study Notes
Perceptual Constancy
- Refers to the ability to perceive objects as stable and unchanging despite variations in sensory input.
- Includes consistent perception of lightness, color, shape, and size across different lighting and viewing conditions.
Shape Consistency
- The brain maintains the perception of an object's shape regardless of the viewing angle.
- This allows recognition of familiar shapes even when they appear distorted.
Size Consistency
- Objects are perceived to maintain the same size despite changes in distance from the observer.
- Our perception compensates for changes in retinal image size caused by distance.
Brightness Consistency
- The perceived brightness of an object remains constant despite variations in lighting conditions.
- This phenomenon helps recognize objects under different lighting environments, maintaining a sense of stability.
