Document Summary
Babies cannot report their perceptual experiences, so researchers must devise reliable methods. Habitual paradigm: after repeated exposure to a stimulus, babies will habituate to that stimulus (stop responding to it, babies generally prefer to attend toward a novel stimulus thus . Present a stimulus until the baby shows very little response (ie. habituates) and then add a new stimulus they can perceive the difference between the 2 stimuli. If the baby shows attention toward the new stimulus, then. Infants are soothed if held when experiencing a painful stimulus, o and especially so when also given something sweet: rooting reflex, and other reflexes present at birth, indicate sensitivity to touch. Infants perceive sounds prior to birth and can even differentiate o between different types of auditory stimuli by week 34 of gestation: auditory threshold- Infants hear well, although not quite as accurately as adults o. Sound pitches in the range of human speech.
