Mirages, for example, are an optical illusion in which the image of the distant object, as a ship, oasis, or water on the dry road ahead or is made to appear nearby. These illusions are perceived without any existence of the stimulus. There are mainly two types of illusions: one is related to physical processes and another is related to cognitive processes. Our past experiences, our fear, and the darkness help to perceive the rope as the snake because the rope and snake have similarities in structure except living and non-living stimulus. The stimulus is exactly like that coming from a snake and it is quite real and objective. Similarly, as we mentioned, the perception of a coil of a rope in darkness as a snake is another example of illusion. It is due to misinterpretations or misperceptions of stimuli that do not correspond to the sensations received by the eye or other senses. The perceptual illusion is a false perception. This is the cause of perceptual illusions in which normal perceptual processes produce perceptual misinterpretations. However, sometimes the brain’s effort to organize sensations into coherent and accurate percepts fails.
Perception provides a clear and meaningful picture of the world around us and shapes our perceptual experience.
It occurs because of confusion, eye movement, emotion, contrast perception, habits, defects of the sense organs, and a tendency towards the wholes. the perception of a coil of a rope in darkness as a snake. The illusion is the misperception or misinterpretation of an individual that comes from a real object.
