Project Details

Description

One aim of this project is to assess the effects of prenatally acquired
familiarity with the maternal voice in a task where newborns can learn to
gain access to either their mother's voice or the voice of another woman,
but are forced to use only their left or right ear. It is expected that
the known maternal voice preference will be greater for infants who use
their left ear. The second aim is to assess the effects of prenatally
acquired familiarity with the mother's language in a task where newborns
can learn to gain access to the familiar language or an unfamiliar
language, bur can use only one ear. It is expected that the known
preference for familiar language will be greater for infants using their
right ear. These finding would directly indicate that the very early
functional lateralization of auditory perception and auditorily-mediated
cognition is not driven only by maturational processes but is also
influenced by prenatal auditory experiences. In brief, the data would
indicate that the very early development of the substrates that permit the
ready development of the uniquely human ability to use and understand
language is also influenced by environmental factors. These data would be
of interest to the disciplines of developmental neuroscience, cognitive
development, hearing and communication science, phycholinguistics, and also
to the clinical disciplines interested in the developmental disorders
affecting hearing, communication and learning.
