How does implicit and explicit knowledge fit in the consciousness of action?

Dienes & Perner's (D&P's) target articles proposes an analysis of explicit knowledge based on a progressive transformation of implicit into explicit p roducts, applying this gradient to different aspects of knowledge that can be represented. The goal is to integrate a philosophical concept of knowled ge with relevant psychophysical and neuropsychological data. D&P seem to fi ll an impressive portion of the gap between these two areas. We focus on tw o examples where a full synthesis of theoretical and empirical data seems d ifficult to establish and would require further refinement of the model: ac tion representation and the closely related consciousness of action, which is in rum related to self-consciousness.
