Document Summary
Determine how people perceive, select, modify and organize stimulation from the environment and organize stimulation from the environment. Motor skills coordinated movements of the muscles and limbs. Habituation when a novel stimulus is presented, babies pay much attention but they pay less attention as it becomes more familiar. Perception often guides a child"s movements, as when vision is used to avoid obstacles. Cells at the top of the nasal passage detect airborne molecules, and smell is the result. Infants are also sensitive to changes in the taste of breast milk, which reflect mother"s diet. 4 months salty and sour, bitter is the last one to develop. Sweet tastes are preferred and bitter tastes are distilled. Newborns have a keen sense of smell; they respond positively to pleasant smells and negatively to unpleasant smells. Certain odor preferences are present at birth such as bananas and chocolate. Amniotic fluid has tastes and smells that depend on mother"s diet and these influences preferences.
