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