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.
Brössel et al. (Mon,) studied this question.
