Document Summary
Brother drummed while sister slept she didn"t even stir later because she got used to it. Our senses are assaulted with stimulation but much of it is ignored. Sensory and perceptual processes: the means by which the nervous system receives, select, modifies and organizes stimulation from the world first step to knowing . Perceptual processes are closely linked to motor skills: coordinated movements of the muscles and limbs. Infants usually prefer novel stimuli over familiar stimuli. Habituation: becoming unresponsive to a stimulus that is presented repeatedly. They found out that babies can distinguish two stimuli (one habituation and one new stimulus) Newborns have a keen sense of smell respond positively to pleasant smell and negatively to unpleasant smells. Can recognize familiar odor (their own amniotic fluid for example, breast milk, mother"s perfume, etc) Highly developed sense of taste they can differentiate salty, sour, bitter and sweet. Most infants prefer sweet and salty over sour and bitter.
