Developmental processes that result in “higher” cognitive functions, like
communication, may have their origins in the young infant’s physical
functioning. Biologically determined sucking and swallowing behavior occurs
from about three months onward in a burst-like manner (a sequence of several
movements followed by a pause), and these behaviors can be regarded as
precursors of turn-taking in a communicative interaction (Kaye, 1977). In this
study, we examine teething (also considered a biologically determined process)
in relation to infant sound production.
