Document Summary
We have unconscious mental mechanisms at work all the time based on our previous experiences we make assumptions. Brain also assumes light objects are automatically grouped together. Sensation: stimuli to nerve impulse: one of the tasks of the brain is to make a correction to turn images right side up the images that come through the retina come in upside down. This area of the eye is very sensitive and adaptive: when injured, vision in that area was blurred. The glasses move the place where the image lands on his retina. If you do an experiment where a person wears these glasses 24/7, a person"s visual perception will adapt. When wearing these glasses, they will no longer see the world shifted. They will see it in the correct orientation. There is great plasticity and adaptation involved in the retina.
