Document Summary

Inforation hunter-gathers: methods for assessing infant perception, habituation, baby is exposed to same stimulus/ becomes bored, preferential looking, where they prefer to look e. g. something novel/new, evoked potentials, electrodes, operant conditioning. Sensitive to cues about the wholeness of objects. Four months old use common motion as a cue: 6 month old"s can determine the boundaries of stationary objects, what captures infants attention, high contrast, contain movement, moderately complex, top heavy. Infants react defensively when objects move towards their face. Same size despite distance: crawling infants perceive depth and are afraid of drop off, gibson and walk"s visual cliff experiment. Innate preference for faces: the vision cliff experiment, hearing. Infants 2-3 months old can discriminate between similar consonant sounds: newborns can hear better than they can see, newborns recognize vowel sounds from their native language, unborn fetuses can distinguish their mothers voice from a strangers voice.
