It seems incontrovertible that information processing is fundamental to cognitive function. As already observed in Chapter 1, one explanatory strategy for a theory of cognition to take is to view some of the agent’s internal states and processes as carrying information about those relevant aspects of its body and external states of affairs in negotiating its environment (Bechtel, 1998, p. 297). Natural cognitive agents produce new information that is intended, amongst other things, to deal with a variety of environments. It is unsurprising then that semantic accounts of computation that underlie CTM view digital computing systems as engaging in information processing at the symbol level (cf. the FSM and PSS accounts).
