AP PSYCHOLOGY

Detailed explanation-1: -Illusions are special perceptual experiences in which information arising from “real” external stimuli leads to an incorrect perception, or false impression, of the object or event from which the stimulation comes.

Detailed explanation-2: -Illusion:Something that looks or seems different from what it is something that is false or not real but that seems to be true or real. Perception: The process by which sensory information is actively organized and interpreted by the brain.

Detailed explanation-3: -Perceptual illusions are defined as consistent and persistent discrepancies between a physiCJIIstate of affairs and its representation in consciousness. It is argued that for the most part these disc. repancies occur mainly as a consequence of the activation of perceptual processes by contrived, artificial stimuli.

Detailed explanation-4: -The Müller-Lyer illusion is based on the Gestalt principles of convergence and divergence: the lines at the sides seem to lead the eye either inward or outward to create a false impression of length. The Poggendorff illusion depends on the steepness of the intersecting lines.
