Orthodox cognitive science takes cognition to consist of or be best explained in terms of computational processes, generally operating on internal representations, whereas non-representationalism and non-computationalism reject this. I.e., the orthodox account of vision sees it as a process of transforming one representation into another (it starts with the retinal image, performs some operation on it, say, finding edges, to give a new representation, then performs some processing on that, etc, until you have a three-dimensional representation or a symbolic representation of the content of the scene). Dynamicism is the view that cognition is best described in terms of the evolution of systems over time and rejects computationalism (which holds that cognition is best described by algorithms; algorithms have an order but do not evolve in time). Non-representationalism just denies that there are any internal representations involved in cognitive processes.
For us lay people, what does it mean for something to be non-representationalist and non-computationalist?
