Physical and cognitive: skill development, newborn, what they do: eat, cry, sleep, non-conscious behaviors facilitate greater growth. If newborn attends to one longer, the newborn recognizes the stimuli are different. Infants prefer facial features over other objects: can"t just show faces and non-faces, need to equate them on contrasts, habituation method, present a stimulus repeatedly while monitoring sucking rate (sucking. =reflex: new things are interesting -> babies suck, over time, infant habituate (gets bored) -> sucking decreases, switch stimulus. Infants come equipped with reflexes and sensory abilities. Immunization: significantly decreased infant morbidity and mortality. In high-risk environments (e. g. environments with bacteria exposure), breast feeding can be critical in reducing infections and disease and in promoting healthier growth: cognitive development, rapid growth. Intellectual growth arguably more dramatic than physical by 1 year. Infants engage in deliberate acts to elicit responses (e. g. wanting to be picked up: memory is robust. Influenced by temperament: experiential influences on separation anxiety.
