Abstract
Interactional expertise is here to stay. Undoubtedly, in some sense of the word, one can attain a linguistic expert level within a field without full scale practical immersion. In the context of the idea of embodied cognition, the claim is provocative. How can an interactional expert acquire full linguistic competence without the simultaneous bodily engagement and real life interaction needed to get the language right? How can one understand the concept of hammering if one has never seen a hammer or felt the weight of the iron head on a fragile thumb? Here I will explore a strange and second-hand way in which bodily engagement could have an impact on our linguistic abilities; this is via the so called mirror neuron system. Since the mirror neuron system blurs the distinction between first and third person activity it can help us understand some of the enigmatic aspects of interactional expertise and pose further questions for research.Keywords: Mirror neurons; Interactional expertise; Contributory expertise; Embodied knowledge; Evolution.
