Jun. 5th, 2008 06:50 amScientists discover how optical illusions work. All of them.
The short version: It takes a tenth of a second for images to get from your retina to the processing centres of your brain. People have known this for decades, but we still see things in real time.
The new theory says that what we're seeing isn't what's there, it's what our brain projects will be there in a tenth of a second - our brain is processing predictively, showing us it's best guess for the future. And that's why optical illusions can fool it, by confusing it into predicting a future that then doesn't happen.
