Studies of Infants' Auditory Pattern Perceptions by Werker and Colleagues

Studies of infants' auditory pattern perceptions by Werker and colleagues at the University of British Columbia found that:

A) infants gradually learn to discriminate more phonemes over the course of their first year.
B) as infants began to speak words in their native language they lost their ability to discriminate between phonemes that were not in their native language.
C) six months old infants could not detect changes in language phonemes that their mothers could not detect.
D) there was a steady decline from birth in infants' abilities to detect phonemic differences regardless of the languages in which the phonemes occur.
