Document Summary

A prerequisite to become a bilingual is being able to distinguish the existence of two different sound systems spoken in the environment. An auditory stimulus is played until the infant habituates to it shown by a decline in sucking. Test phase: either the same stimulus or a different one is played. If the infant notices a change they will increase the frequency and strength of sucking: operant head turn: used with younger children and attention is focused on the experimenter. A stream of stimuli from one speech category is played. The child is conditioned to turn head away from experimenter and towards a speaker where there is a change in speech. Experiment: more subtle distinctions: orientation time: child"s attention is drawn either to left or right speaker by a flashing light, speech is played. The dv is how long the child continues to look at the speaker. Test phase: speech from either familiarized language or new language.
