Abstract: According to an influential view, one function of mirror neurons (MNs), first discovered in the brain of monkeys, is to underlie third-person mindreading. This view relies on two assumptions: the activity of MNs in an observer’s brain matches (simulates or resonates with) that of MNs in an agent’s brain and this resonance process retrodictively generates a representation of the agent’s intention from a perception of her movement. In this paper, I criticize both assumptions and I argue instead that the activity of MNs in an observer’s brain is enhanced by a prior representation of the agent’s intention and that their task is to predictively compute the best motor command suitable to satisfy the agent’s intention.
