Document Summary
Have biological rhythms (behavior follows regular patterns of biological behaviors, circadian rhythm or sleep-wake cycle) Attracted to visual stimuli (faces, specifically care-givers over strangers by 3 months, and eyes by 2 months) Attend to voices (figure out source of voice, elongating vowels, infant-directed speech aka baby talk, speak slower, shorter sentences, helps development of language) Differentiate odors, and tastes (smell of mom and her milk vs other moms) Need touch for healthy development (happier and less fussy when cuddled) helps with infant survival - because infants are dependent on others, they are biologically prepared to deploy reactions that call for caregiver"s attention. Infants learn to initiate and respond (contingent interactions, learn that others are respondent to them, behaviors and facial expressions can provoke others" reactions, can be initiators) Unused connections are eliminated (5-7 years, frontal cortex - think more complexly, control impulses, plan and organizing, associated with social skills and developing interactions with peers)
