The empirical programs we describe below have their own momentum, independent of any connection with philosophical issues. In particular, we do not argue that the Desert Song case, or any of the other examples of collaborative recall which we discuss below, entails any particular view on whether cognition and memory are in fact often extended or distributed. Theorists can continue to treat each individual’s cognitive processes in isolation, as occurring solely within the head, even if causally triggered or cued by non-cognitive external input. (Sutton, Harris, Keil, & Barnier).
Sutton’s project, they say, ‘can be undertaken while leaving much of the cognitive psychology of memory as the study of processes that take place, essentially without exception, within nervous systems’ (2008, p.179).So, why do Sutton, et al., want to disagree with us? We seem to be on the same page.
