ABSTRACT
How flexible is the human visual system? When confronted with optical inputs that are systematically distorted, does the visual system become recalibrated (perhaps by making use of undistorted information from other sensory modalities, such as touch), to counteract the distortion and restore perception to normal? When exposed to stimulation that is unchanging and redundant (and therefore less informative than variations) does the visual system become recalibrated to nullify or discount the redundancies?
