This literature review is focused on the External Mind Thesis, which lies in the field of Cognitive Science, more specifically under Embodiment Theory. The purpose is to encourage future research on the Extended Mind Theory and elaborate on a few research methods.

Literature focusing on the different types of memory processes are essential to successfully approach extended mind research or any other cognitive process. An overview about the behavioral observation method and coding mechanisms are included. Lastly, this review is wrapped up through an example of how this information could come into play in a real life External Mind research scenario. Results could potentially change the way people think about and use mechanisms such as pen and paper.
