According to the extended cognition thesis, an agent’s cognitive system can sometimes include extracerebral components amongst its physical constituents. Here, we show that such a view of cognition has an unjustifiably anthropocentric focus, for it tends to depict cognitive extensions as a human-only affair. In contrast, we will argue that if human cognition extends, then the cognition of many non-human animals extends too, for many non-human animals rely on the same cognition-extending strategies humans rely on. To substantiate this claim, we (...) will proceed as follows. First (Sect. 1), we will introduce the extended cognition thesis, exposing its anthropocentric bias. Then, we will show that humans and many non-human animals rely on the same cognition-extending strategies. To do so, we will discuss a variety of case studies, including “intrabodily” cognitive extensions such as the spinal cord (Sect. 2), the widespread reliance on epistemic actions to solve cognitive tasks (Sect. 3) and cases of animal cognitive offloading (Sect. 4). We’ll then allay some worries our claim might raise (Sect. 5) to then conclude the paper (Sect. 6). (shrink)

This paper outlines three broad conceptual schemes currently in play in the sciences concerned with explaining cognitive abilities. One is the anthropocentric scheme – human cognition – that dominated our thinking about cognition until very recently. Another is the cybernetic-computational scheme – cybernetic cognition – rooted in cognitive science and flourishing in such fields as artificial intelligence, computational neuroscience, and biocybernetics. The third is an evolutionary biological scheme – phylogenetic cognition – that conceptualizes cognition in terms of the phylogeny-based approach (...) we take to all other traits of evolved organisms. It shows how these conceptions ground different research questions and methods, and how their relationship is still in flux. (shrink)
