Document Summary

Binocular depth cues retinal disparity: what each eye sees is a little different. The amount of disparity (difference) between the two images can be used as a cue for distance: used in 3d movies, some children have difficulties with this strabismus, but motion parallax can help. Prosopagnosia: can selectively lose the ability to recognize faces. Habituation: present same stimulus over and over till babies bored, useful for testing because orienting something new means children noticed a change, rapid habituators tend to be smarter. Hearing: newborns hear well, though not quite as accurately as adults, could be because of fluid in the ear canal, or lack of experience. Infants" hearing is best for sounds that have pitches in the range of human speech. Smell is more sensitive: olfaction tested with facial expression, and preference, newborns react strongly to vinegar, ammonia, rotten eggs, shrimp, 1-week-old"s recognize mom"s odor: breast smell.
