Young Children Understand Different Dialects
We are surrounded by a multitude of different accents every day. Even when a speaker of another English dialect pronounces words differently than we do, we are typically able to recognize their words. Psychologist Catherine Best from MARCS Laboratories, University of Western Sydney, along with colleagues from Haskins Laboratories and Wesleyan University, report a ground-breaking study on the early development of this cross-dialect skill, which they term "phonological constancy."
In this experiment, 15- and 19-month-old American toddlers looked at a colored checkerboard on a monitor in order to hear sets of familiar words or unfamiliar words. They completed two tests, one with their own American dialect, and the other with a Jamaican English dialect.
The authors conclude that phonological constancy, along with the complementary ability to differentiate words from similar-sounding words or nonwords (known as phonological distinctiveness), "together serve as a solid foundation on which children rapidly build a vocabulary, and later extrapolate from spoken language to the world of reading."
