Out of sight, out of mind? Not really

Out of sight, out of mind? Not really: "Because the brain is effectively blind during the one-twentieth of a second of each eye movement, subjects could not see the object substitutions being made and were completely unaware that the altered visual world behaved any differently than the real world.

But their brains detected the difference.

In tests following one or two hours of exposure to the altered world, subjects confused objects that had been swapped-in reliable and predictable ways. Subjects judged different objects to be the same object at different locations, as if their brains used their eye movements to learn what images belong together to make an 'object.' "
