Document Summary
Page 156-180, 25 pages page 1 of 7. Basic sensory & perceptual processes: sensory and perceptual processes are the means by which people receive, select, modify, and organize stimulation from the world. Each sense organ translates physical stimulation into nerve impulses: perceptual processes are closely linked to motor skills with coordinated movements of the muscles and limbs. By presenting the same stimulus repeatedly and then a novel stimulus, researchers see if the infant responds with habituation or with new behaviour that demonstrates ability to distinguish the two: faster habituation predicts later intelligence scores. Smell, taste, and touch: infants have a keen sense of smell, responding with the appropriate facial expressions to pleasant and unpleasant smells. They can also recognize familiar odours, such as their own amniotic fluid, or their mother"s breast: infants differentiate readily between tastes, particularly reacting to sweet substances favourably.
