Sensory Adaptation:Our sensory systems can adapt and become less sensitive to stimuli over time. For example, if we are exposed to a bright light for a while, our eyes will adjust and perceive subsequent lights as dimmer.
Color Constancy:This refers to our ability to perceive an object's color consistently despite variations in lighting conditions. Our brain compensates for changes in illumination so that objects appear relatively stable in color.
Opponent-Process Theory:According to this theory, our perception of color relies on three pairs of opposing color receptors (red-green, blue-yellow, black-white). When one receptor is stimulated, its opponent is inhibited, allowing us to see colors in relation to each other.
