The work of Colwyn Trevarthen at Edinburgh University demonstrates that the child is born equipped for social interaction, and expecting to be a subject among subjects. The child interacts with its environment, both natural and social.
The video evidence he has collected is so compelling that no room is left for doubt: the child’s world is one of intersubjectivity.
In one piece of video we see a father holding hidden in his coat a premature baby. The baby utters short passages of squeaks, pausing for a response from the adult. A dialogue is established in which both parent and child play equal and determining roles. The roots of social interaction, language and musicality are revealed.
