Abstract

The time frame for infants' acquisition of language constancy was probed, using the phonetic variation in a rarely heard accent (South African English) or a frequently heard accent (American English). A total of 156 Australian infants were tested. Six-month-olds looked longer to Australian English than less commonly heard South African accent, but at 9 months, showed similar looking times. With the more frequently heard American accent, 3-month-olds looked longer to Australian and American English, whereas 6-month-olds looked equally. Together these results imply that in the 1st year, differential attention to native versus nonnative accents decreases as infants develop a sense of language constancy for the common native language. However, experience with the nonnative accent can expedite this process.
