What's in a face? How about this face?
This famous face is just a mask, yet it is a powerful reminder of the power that our knowledge and beliefs have on us. For your life, you have a particular exposure to faces. This visual input shapes your knowledge and expectations over time to the point that, even in the face of contrary physical stimuli, you will see what you expect, you will see what you have grown to understand as normal. In this case, the visual system does not see inverted faces, and in the presence of one, reverts to its knowledge of faces with their noses pushed out. Pretty amazing huh?! What's More amazing is that by understanding the visual system we can predict how people will respond to each other, how to increase teamwork, how to make better movies, and more!
Vision science is so fun!
