June 3rd (No oohs and ahhs) by Virgil Arles I'm Not Here (Instrumental) by Graphite Man Diana Deutsch and neuroscientist Dana Boebinger explain why our hearing is a unique sense and why sonic illusions can fool us.

What we hear is incredibly personal and we all hear things differently. The symbols create the illusion.This episode was written and produced by Carolyn McCulley. But the one with the feather looks longer or bigger. Muller Lyer illusion: Both arrowheads and the feather-headed lines are the same lengths. There are several examples of size illusions. The theory of misapplied constancy suggests that we perceive some parts are farther away than others. Illusions of size occur because we perceptually distort the length of various lines. There are countless illusions related to cognitive processes, that can be broadly divided into two categories: Illusion Due To Cognitive ProcessesĬognitive illusions occur in the presence of the stimulus but the individual simply misinterprets the situation or the stimulus. These illusions are something that falsely appears to be real. If it is caused by the refraction of light rays from the object through layers of air having different densities as a result of unequal temperature distributions. ![]() 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. ![]()
