  Close kin to embedded cognition, extended cognition moves from the claim that cognition is embedded to claim additionally that the environmental and social resources that enhance the cognitive capacities of an agent are in fact constituents of a larger cognitive system, rather than merely useful tools for a cognitive system that retains its traditional location wholly within an agent’s nervous system (Clark and Chalmers 1998; Menary 2008). Some interpret the thesis of extended cognition to mean that cognition actually takes place outside the nervous system—within the extra-cranial resources involved in the cognitive task (Adams and Aizawa 2001; 2008; 2009; 2010). Others interpret the thesis more modestly, as claiming that parts of an agent’s environment or body should be construed as parts of a cognitive system, even if cognition does not take place within these parts, thus extending cognitive systems beyond the agent’s nervous system (Clark and Chalmers 1998; Wilson 1994; Wilson and Clark 2001).
