Optical illusions are all around us(explain). The brain remembers what it has seen before, then when it sees something similar it takes shortcuts when looking at a new images. This causes the brain to make mistakes and creates optical illusions. An optical illusion is a misleading image that deceives the eye. Different people see optical illusions differently because of their previous experiences. Previous experiences help the brain interpret what it sees. If your previous experiences determine what you see, dose age affect your susceptibility to optical illusions and which age is most susceptible? I age does affect your susceptibility to optical illusions. I also believe that the middle age group sixth and seventh graders will see the illusions best because they have enough life experiences without having too many to cloud their judgment. I used 3 test groups 2nd graders 6/7th graders and adults. The researcher used five optical illusions Eureka , Scary Faces, Animal Man, Horses, and Jesus (explain). I used a measuring tape to locate the appropriate placement of the tape which was placed on the floor to mark the location of where the test subject stands while looking at the optical illusion. Each illusion was then placed on a stand. The tape was placed at two feet increments, the last mark was 20 feet away from the illusion(DEMO). I concluded that the adults were able to see the optical illusions the best because even though the adults have lots of vision problems, they had so many life experiences that their susceptibility was high. My hypothesis was incorrect. The overall average % is; adults about 50% 6/7th about 40% and 2nd about 25%Adults 49.38%, 6/7 th graders 41.23%, and 2nd graders 24.77%.
