As infants begin to learn words with earnest in their second
year of life, they must not only learn which distinct combination of sounds
maps onto the label of an object but also be flexible in this knowledge to
account for variability in the signal (e.g. speakers, accents, etc.). Over a decade of research has investigated
the phonological detail with which infants encode familiar words by examining
their recognition of correctly pronounced (dog)
and mispronounced (tog) words. Using
a meta-analytic approach, we capture how sensitivity to mispronunciations changes
as infants mature.
