Document Summary
What is the function of perception: to see the world as it really is, to see the world accurately, to see pretty things. Babinski re ex: stroking middle of foot of baby causes his to are toes. Acuity in newborns: baby will orient to larger things over smaller things, very underdeveloped visual acuity of around 20/600, see at 20 feet what a normal adult can see at 600, doesn"t reach adult levels until around 5. The development of colour perception: born black/white, some color perceptions though (prefer color, newborns discriminate between only red and green, whereas 4-month-olds have nearly adult- like color vision. Cues to depth, then: self-propelled locomotion, texture gradient. De ne constancies : the perception of like objects as like (in terms of size, color, lightness, and brightness) despite radically different projections on the retina, so sailboat, even when it"s far away or close (size constancy)
