Document Summary
Percepion: the process by which agents interpret and organize sensaion to produce a meaningful experience of the world. From a cog. science perspecive, it means turning informaion from one form into new, meaningful representaions. Atypical: senses in bowel, stomach, pain receptors, heat receptors, etc. Extramission theory: rays of light emanaing from the eye in combinaion with light in the world allow us to see. Intromission theory: visual percepion is accomplished by rays of light relected from objects into the eyes. Light is relected into the eye and focused on the reina. Cone: three types: correspond to short (blue, medium (green, long wavelengths (red) Works best in bright light; fewer cone cells exist for peripheral vision. Perspecive: things are smaller on the fovea as they get farther. Occlusion: when one thins is in front of another. Texture, shading, saturaion: closer things are more saturated. Focus muliple images: including moion and binocular vision.
