Sensation and Perception Unit -4
How we sense the world creates and shapes our reality: This unit is about how we sense and perceive and construct the world from a biological perspective, rather than a cognitive one which we later construct into a schema or paradigm.
I really like illusions that seem to move. Stare hard at any one part and it should stop for you.
This might be my single favorite illusion of Brightness Constancy. Square A and Square B are the same color: exactly the same. Try holding paper over the other squares to see. Some people have even printed it so they could place a cut out over it to test it, others have used photoshop to take samples of both colors to compare. A and B are honestly the same color, it's so compelling and there's really no way to make your brain see it correctly.
Another moving one. Love it.
This is VantaBlack. Made in a lab with Carbon Nanotubes. It's absorbs 99.965% of light (see the gift). It makes anything look completely flat as there isn't any color variation or shadow, at all. Could even be dangerous if it "got out."
The Muller-Lyer Illusion. Click on it and go to the webpage and see how you do trying to guess when it's in middle.
This "dancer illusion" is very famous. The idea is that you can see her spin clockwise or counter clockwise. It's hard for some people.
This is linked to a video that puts in some very subtle lines that give your brain all it needs to see it spin either CW (clock wise), or CCW (counter clock wise).
Figure-Ground Illusion. What is the "figure," what is the background.
This is a great illusion. It seems you're looking at a spiral. However, it's really a series of circles. Hold up a something round to the screen, or just trace one of the circles with your finger, pencil, etc...
