PERCEPTUAL ILLUSIONS

 

         The dictionary definition of a perceptual illusion is, "the perception of something objectively existing in such a way as to cause misinterpretation of its actual nature." While this is true, it is not the only definition of an illusion. An illusion is not always a misinterpretation, but rather it convinces us that the real life version of an object is untrue or false. One important factor to remember is that no two different interpretations of an object of picture can be given at one moment.

         We have sensory receptors in our brain that detect light, sound, temperature, etc., and most of these receptors are on the surface of our bodies (i.e. eyes, ears, mouth, etc.). There are, however, internal receptors such as those that register pain. Regardless of the type, each receptor is responsible for detecting its own form of energy which is used to transmit signals to the brain. When the brain receives these signals, most of the time it interprets the signals correctly, but when it doesn't, that is what we call an illusion.
