It is tough to believe that infants can between languages, however, recent research has shown that infants as young as 11-months old can learn to associate the language they hear with ethnicity.
The study conducted in Vancouver was published in the journal 'Social Sciences and Humties Research Council of Canada'.
"Our findings suggest that by 11 months, infants are making connections between languages and ethnicities based on the individuals they encounter in their environments. In learning about language, infants are doing more than picking up sounds and sentences--they also learn about the speakers of the language," said Lillian May, the lead author of the study.
The researchers played English-learning infants of Caucasian ancestry sentences in both English and Cantonese and showed them pictures of people of Caucasian descent, and of Asian descent. When the infants heard Cantonese, they looked more at the Asian faces than when they were hearing English. When they heard English, they looked equally to Asian and Caucasian faces.
"This indicates that they have already learned that in Vancouver, both Caucasians and Asians are likely to speak English, but only Asians are likely to speak Cantonese," noted Janet Werker, the study's senior author.
The researchers showed the same pictures to the infants while playing Spsh, to see whether they were inclined to associate any unfamiliar language with any unfamiliar ethnicity. However, in that test, the infants looked equally to Asian and Caucasian faces. This suggested that young infants pick up on specific language-ethnicity pairings based on the faces and languages they encounter.
"Babies are learning so much about language--even about its social use--long before they produce the first word," said Werker.
"The link between speaker characteristics and language is something no one has to teach babies. They learn it all on their own," added Werker.
