Document Summary
The newborn"s readiness for life: all their senses: in good working order, see/hear well enough to detect what is happening around & respond adaptively, reflex: involuntary & automatic response to stimulus (eye blinks in response to puff of. Infant states: newborns display organized patterns of daily activity, predictable, foster healthy dvlpmntal outcomes, moves in and out of 6 infant states/level of arousal, during 1st month, baby moves rapidly from states. Research methods used to study infant"s sensory & perceptual experiences. The high-amplitude sucking method over sensory env: when infant sucks faster/harder than baseline, trips electrical circuit & introduces sensory stimulation, once interest wanes & sucking returns to baseline, stimulation stops. If 2nd stimulus elicits increase in high amplitude sucking, could conclude has discriminated 2nd stimulus from 1st. Hearing: soft sounds adults hear must be much louder before neonate can detect, neonates can discriminate sounds that differ in loudness, duration, direction & freq.
