Topic: Infant Vocalizations as Signals of Developmental Progress to Caregivers
This dissertation evaluates the role of prelinguistic vocalizations as indicators of developmental progress, i.e., fitness signals, with respect to evolutionary-developmental theory. This research is founded in the notion that infant vocal stages follow a natural logic of development foundational to language in humans and high rates of prelinguistic speech-like vocalizations, or “protophones,” may be under positive selection pressures to signal wellness and developmental wellbeing to caregivers.
