Publisher Summary(#br)The chapter discusses the interactive model. Encodingism focuses on elements of representation. Interactivism requires a shift to a view of representation as being a functional aspect of certain sorts of system processing. This shift from representations as elements to representation as function is critical. This chapter presents only the most basic core of the interactivist explication of representation. The general interactive model is a programmatic approach to all epistemic and mental phenomena and has been developed in a number of directions. It gives a brief look at the evolutionary foundations of the model, the general approach to perception, a constructivist consequence for development, and the basic nature of the model of language. The evolutionary... foundation of interactivism consists of a sequence of knowing, learning, emotions, and reflexive consciousness that form a trajectory of macro-evolution. Interactivism imposes distinct logical constraints on models of learning. The chapter focuses primarily on the implications of a shift to process ontologies for representation and language, but the general ontological psychology approach, of which interactivism is a part, attempts to go far beyond those.
