Do you know where you are? Body and self not the same

A study by Arthur B. Markman and C. Miguel Brendl found that people's representations of self are distinct from their body representations, suggesting a temporary localization of the self in virtual environments like video games. This external representation affects how players perceive and act, potentially leading to a merge of both b...
