Document Summary
Mechanism to parse speech sounds for any human language. Suck rapidly if interested; reduce speed upon habituation. After habituation, if infants recover sucking speed (dishabituated) they can discriminate. If child turns their head towards the loud speaker when they hear a speech sound change. Rewarded with viewing a toy in that location. Turning head without hearing speech sound does not result in a toy. Play different sounds, when speech sound changes, does the infant look to the toy booth. 7 month olds discriminated 80% of speech sounds. 100% for salish and only 30% for english adults. Older infants who were successful did not need more trials to make discrimination. No significant difference between (6 - 8) or (8 - 10) But, (10 - 12) months performed significantly worse on the discrimination tasks. Each baby is different in when they lose the ability. Able to discriminate the majority of sounds not present in native language.
