when we look at something, light rays enter the pupils of each eye projecting an image on the retina at the back of the each eye, not only are the images small,blurred and upside down but there are two of them . from this crude sensory input we are able to percieve one clear, there dimensional coloured image, which is the right way up. the process whereby these crude images are interpreted and understood is called perception. perception is the process of interpreting,organising and elaborating sensations. and it is the subject of this chapter.
the sensory imformation for vision is the light waves that when they strike the retina, are changes into electrical impulses that are transmitted to the brain. we make sence of this information interpreting it organising it and elebaborating on it the brain also is able to to fill in any gaps in our sensation in order to make an object appear whole.
