YC vocalization maintained the same levels from baseline to social response. CC infants produced more symbols during the social response period than the YC infant. Social interactions increased vocalizations and had more developed syllable structure. Infant sounds were associated with the behavior of their caregivers.
Infant babbling relates and is related to social interaction. Babbling still changed without vocal imitation fro mothers, they responded with smiles, touch, and moving closer. These results contain notable parallels between to social mechanisms of vocal learning in songbirds. In both young songbirds and babies their immature output has significance in later communication development. This essay highlights the importance of interaction between infant and caregiver in the early stages of speech.
This experiment showcases the similar learning mechanisms have the ability to impact development in songbirds and human babies. The actions of caregivers affect the vocal development in human infants. Similarly, adult songbirds affect the vocal development in young birds with the use of gesture, much like in humans. Research in this experiment help reveal the value of songbirds models and propose that performance processes impact early maturity of vocal
