Solving the interface problem: from intentions to motor representations through conceptual spaces

To explain intentional bodily action, we must address the Interface Problem: how propositional intentions and non-propositional motor representations integrate non-accidentally. Two requirements arise: matching, ensuring a motor representation corresponds to an intention despite format differences, and selection, choosing one motor representation among multiple matches. We combine Gärdenfors’ conceptual spaces with Bayesian inference to meet both requirements.
