(visible light) can only detect a narrow part of the electromagnetic spectrum ‚ visible light. To some extent we can detected a small amount of infra red by the heating action. We detect the visible light spectrum by the special cells located on the retina in our eye. Humans have coloured binocular vision. reasons for this: active mainly during the day colour vision is important to distinguish information about the environment- food sources‚ interpersonal relationships etc Other animals:

All three vertebrate classes share two pathways‚ one which projects from the retina to the dorsal thalamus and then to the telencephalon and one which travels first to the optic tectum and from the tectum to the dorsal thalamus before projecting to the telencephalon.

system refers to an automated system that can identify an individual by measuring their physical and behavioral uniqueness or patterns‚ and comparing it to those on record. It can identify fingerprints‚ face‚ iris‚ palm prints‚ signature‚ DNA‚ or retinas of an individual for easy and convenient verification ( www.ex-sight.com ). This system was first used by the Chinese in 14th century where merchants used children’s palm and footprints to distinguish them from one another. When this kind of high-tech

in the sensory information received by the retina. For example size constancy. When we see a person an extremely small person walking next to a person of normal size we understand that a person cannot physically be that small‚ and therefore must be further away. Another perceptual constancy is shape constancy‚ where we understand that a shape is the same regardless of which angle we see it from‚ even though it may produce different shapes on the retina. We also see different shades of a colour (changed
