Document Summary

Testing phonetics and phonology: habituation: presenting the same stimulus repeatedly, it habituates, and then infants look to new stimuli, conditioned head turn: originated as an auditory clinical test. Infants are placed on their parents lap, across from experimenter #1. The infants are rewarded when they turn their head to a new sound, and not rewarded for incorrect head turns. There is eventually an increased delay between the sound and the reward. Eventually the kids are conditioned to turn their head when they hear a new sound. Then closer sounds like pai and bai to see if they can hear the difference. Infants are measured based on hits and misses, could be a % the infant got corrected, or by a criterion of head turns. Fetuses: have auditory capabilities in the third trimester. They respond differently to the voices of their mothers rather than strangers once they are outside of the womb. This is because their mothers voice is more familiar.
