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) by six months old,infants could not detect changes in language phonemes that their mothers could not detect.
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) there was a steady decline from birth in infants' abilities to detect phonemic differences regardless of the languages in which the phonemes occur.
D) as infants began to speak words they develop their ability to speak words in both their native and non-native language.
