| Abstract |
The purpose of studying perception vs. illusion is to attempt to illustrate and understand how our eyes and brain work in combination with each other to sometimes give use false information about the world around us. In basic terms, illusions are the result of confusion between our senses and the brain. There are three classes of visual illusions. The first is optical which can be characterized by visually perceived images that differ from objective reality. The second is physiological illusions such as the after images following bright lights and finally, cognitive illusions which come from interaction with assumptions about the world, leading to “unconscious interferences”. The human brain constructs a world in your head. It’s almost like a computer. It is wired to remember certain things and react to others. It takes information from your surroundings and keeps it as evidence, then giving it out to your nervous system. Unfortunately in the case of illusion, those signals can sometimes be wrong. |
