- 17. Fictions These illusions cause us to see things that are not true.
- 18. A paradox is something that may appear ridiculous but is actually true. These illusions are also called impossible figures because they are impossible. If you tried to make these into real (3D) objects you would not be able to. Paradox

Editor's Notes
- When information from the outside world reaches us, either by touch, sight, smell taste or hearing, we make sense of what that information is in order to identify it.
- “ WE DON’T SEE THINGS AS THEY ARE, WE SEE THINGS AS WE ARE.”
- In this picture the word a is written twice, but most people don’t notice because in our previous experience sentences usually make sense.
- We notice stimuli that come within range for even a very short time if we choose. That’s why Cadillac developed a 5-second commercial to illustrate that Cadillac’s can go from zero to 60 in less than 5 seconds.
- An illusion is a perceptual mistake. They occur when we misinterpret an image or have trouble seeing it for what it really is.Illusions occur because our brains make guesses about what we are looking at. This is usually a very rapid process which happens without us noticing.When we look at something our brains use the knowledge that they have stored over a lifetime to help us decide exactly what it is we are seeing.
- Because there are two or more likely explanations of the image, when the brain tries to guess what it is seeing, it cannot decide which guess is best.
- Sometimes this information can lead us to make the wrong decisions, but our minds are so set on these rules that they find it hard not to use them, even when you know the reality
- The Kanizsa triangle: Looking at this picture we have the impression that there are two triangles, one that is drawn with a black line and one that is white. The white one appears on top of the line one. There appear to be three circles covered partially by the corners of the white triangle. But there actually no triangle or circles! We create the triangles in our minds. They are not really there. They are fictional. This is because our brain decides that it is more likely there are triangles than these strangely arranged shapes, so that is what we see.
- Objects will be perceived as a group when they have similar physical shapes to each other.
