Perceptual Constancy

Perceptual constancy is the brain's ability to recognize that objects remain the same even when their appearance changes due to different viewing conditions. For example, a car maintains its size, shape, and color whether it's seen in bright sunlight or shadow, from afar or up close. This process helps us perceive a stable and consistent environment, allowing us to identify objects accurately despite variations in lighting, angle, or distance. Essentially, perceptual constancy ensures our perception of the world remains reliable, providing a coherent understanding of our surroundings despite sensory changes.
