Experiment 2
Optical Illusions: Can the eye be fooled?
Purpose/Hypothesis
After the lenses in your eyes focus light, your brain must make sense of the images formed. This is not always easy. Optical illusions occur when the brain is tricked into thinking things are not as they are. These illusions use the way your brain processes optical information to fool you into seeing things that are not there.
Examining how people react to optical illusions will help you understand how the eyes and brain work. In this set of experiments, you will explore how people perceive images. For each of the images illustrated on the following pages, write a hypothesis about what people will see. For example, for the second picture, you will ask ten people this question: "Which figure is larger?" How do you think people will answer?
