Study Notes
Perceptual Constancy
- Objects are perceived as constant despite changes in illumination or retinal images.
- Perception remains stable even when sensation fluctuates; the brain interprets a consistent image regardless of variations in input.
- The change in the image on the retina does not alter the perception of the object’s characteristics.
4 Major Types of Perceptual Constancy
- The four key types include Shape Constancy, Size Constancy, Lightness/Brightness Constancy, and Color Constancy.
Shape Constancy
- Familiar objects retain their perceived shape even when the image on the retina changes due to movement or perspective.
- The perception of shape remains constant despite variations in viewing angle.
Size Constancy
- Objects are perceived as having a uniform size regardless of their distance from the observer.
- Size perception is stable even when the actual retinal image size alters due to distance changes.
Lightness/Brightness Constancy
- Objects are perceived to have a constant color despite changes in illumination levels.
- Although the amplitude of reflected light may vary, the frequency remains consistent; thus, color is perceived without alteration.
Relative Illumination
- Refers to the amount of light that an object reflects compared to its surrounding environment.
- Influences how brightness and color are interpreted by the brain, aiding in the perception of consistency.
Color Constancy
- Color perception is affected by surrounding context and lighting conditions.
- An object may appear differently colored when viewed in different environments, illustrating the brain's reliance on contextual information for accurate color recognition.
