Sutton's Project and Intracranialism

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). We disagree: this reversion to internalism is not an implication of Sutton’s view. (Sutton, Harris, Keil, and Barnier, forthcoming, pp. 8-9).

I think there is a misinterpretation here.  The A&A claim (as one can see from the fragment that Sutton, et al., quote right there) is that Sutton's project can be undertaken ...  It is not that Sutton's project requires or implies that cognitive psychology of memory is, or must be, the study of processes that take place, essentially without exception, within nervous systems.  So, the earlier comment Sutton, et al., made on this score is not a mere typo or accidental infelicity in wording.  They seem genuinely to have mistaken the A&A claim.
