Here’s the penultimate draft of the aforementioned paper by Julian Kiverstein and Mirko Farina:
Abstract: Like many other studies, this paper focuses on the ways in which the functional isomorphism between neural and extra-neural features can provide the means to meet the criteria for cognitive extension. However, unlike these other studies, this paper acknowledges the stalemate into which the debate over Extended and Embedded has fallen. While surveying the literature directed at the functionalist version of Extended Mind, we investigate the feasibility of the complementarity approach. By exploring the offshoots of recent studies encompassing developmental niche construction, neural development and nurtured cognitive structures, we attempt to validate this complementarity alternative and in bringing it back to fore thereby escape the apparent impasse.
