Guess who's talking? Tuning the infant speech bias
Abstract:
Developing organisms across the animal kingdom show biases for
perceiving and learning about the vocalizations of their conspecifics.
Do young humans show similar biases for spoken language? In this talk,
I will present evidence from several studies examining the listening
preferences of young infants, including newborns. Together these
studies will show that young infants are born as selective listeners,
but that this selectivity is subject to further rapid tuning in the
first few months of life. This pattern of findings is consistent with
recent findings in infant face perception, and is suggestive of common
developmental principles, such that initial universal processing
abilities become tuned to conspecifics. Finally, I will discuss some of
the functional consequences of a bias for speech - that it might be
useful for figuring out who, or what, is talking.
