Document Summary
People are biologically prepared to perceive the world in certain ways. The visual system includes two main subsystems: ventral: carries information in large part to the temporal cortex of the brain. It recognizes and represents the visual world: dorsal: carries information to the perceptual cortex. Aspects of both systems are functional in the first half year of life. We perceive the world through sensory systems: vision, audition (hearing), gestation (taste), olfaction (smell) and a few others. Example: in a jungle and you see a tiger, you turn your attention towards it, identify it and locate how far away it is from you and where it is heading. The lens bends the light rays to protect a focused image on the light-sensitive retina. Two methods for studying visual perception: preferential-looking: when an infant looks more at one object than the other object because of a preferred difference.
