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.
