 A distinction is sometimes drawn between distributed and extended accounts of cognition, with the former referring to a line of research in cognitive science that focuses on cognition in complex sociotechnical systems consisting of multiple human and technological components (Hutchins 1995) and the latter to a current in philosophy of mind that focuses on cognition in systems centred on human subjects augmented by technological or sometimes social resources (Clark &amp; Chalmers 1998). Accounts of both sorts are committed to the rejection of traditional “intracranialist” views of cognition and their replacement with the “extracranialist” view that cognition sometimes exceeds the bounds of the individual brain, and the difference between them may thus be merely one of emphasis, as distributed cognition theorists emphasize remembering in sociotechnical systems, while extended cognition theorists emphasize remembering in technologically-augmented individuals. Thus Hutchins (1995) considers how a cockpit—or rather the system consisting of the pilots of an airliner plus various instruments—remembers its speeds, while Clark and Chalmers focus on the case of Otto, a (hypothetical) Alzheimer’s patient who relies on a notebook to supplement his unreliable memory. While both accounts are in agreement on the point that external resources may count as memory stores only in the context of larger systems, both confront us with the role of various forms of external memory in human remembering.
