 In its earlier incarnations, the scope of extended mind was relatively restricted, it being understood, primarily, as a thesis about cognition. The types of external structure or activity involved in developing the idea of extended mind reflected this focus on cognition. They were predominantly thought of as structures that carried information pertinent to the solution of cognitive tasks that an organism might face, where the organism, through acting on these structures, could transform this information from information merely present in the structures to information that is available to the organism (Rowlands 2010). Accordingly, expansion in the scope of extended mind can, and has, occurred along two (related) dimensions: (1) expansion in scope from cognition to other kinds of mental process, and (2) expansion in the types of external structure involve in these extended mental processes.
