Recall the technique used to assess newborns: kuhl and miller (1975) Method: habituation paradigm (human-has aka high- amplitude sucking) (chinchillas-orienting) Results: for infants, ss long as your start the vibration at 20 mm or more, 100% of the infants perceived the phoneme correctly. (fyi- adults perform the same way). Conclusion: at least hearing 20 mm, sound is correctly categorically perceived: perception of continuous speech, ramus et. Method: habituation paradigm (humans has, tamarins head- turning) Stimuli: speaker a vs. speaker b could be japanese or dutch, both played forward or reverse.
