Enaction has been seen as a move to conjoin representationalism with phenomenalism, that is, as adopting a constructivist epistemology, an epistemology centered upon the active participation of the subject in constructing reality.[1][2] However, 'constructivism' focuses upon more than a simple 'interactivity' that could be described as a minor adjustment to 'assimilate' reality or 'accommodate' to it.[3] Constructivism looks upon interactivity as a radical, creative, revisionist process in which the knower constructs a personal 'knowledge system' based upon their experience and tested by its viability in practical encounters with their environment. Learning is a result of perceived anomalies that produce dissatisfaction with existing conceptions.[4]
