What causes a perceptual illusion?
Many common visual illusions are perceptual: they result from the brain’s processing of ambiguous or unusual visual information. Other illusions result from the aftereffects of sensory stimulation or from conflicting sensory information. Still others are associated with psychiatric causes.
Why does perceptual illusion occur?
when the representation at the eye (retinal image) is variant with change in observer position, posture, and movement. These constancies are consequent on stimuli for object distance and observer posture and motion. When the retinal image is invariant and these stimuli are manipulated, perceptual illusions occur.
What is illusion and types of illusion?
