The link between these arguments, the embodiment debate and the idea of interactional expertise is the importance of natural language. If interactional expertise exists then it suggests that people who cannot perform a particular task or skill – and who therefore cannot have the embodied expertise associated with it – can still talk about that skill as if they did possess the embodied skills. Interactional expertise thus raises a key question about the “amount” of embodiment that is needed for expertise to be transferred. For proponents of the embodiment thesis, quite a lot of embodiment is needed as the expertise resides in the relative position, movement and feel of the body. From the perspective of interactional expertise much less embodiment is needed and, taken to its logical minimum, perhaps only the ability to hear and speak are needed.
