based on linguistic abstractions grounded on perceptual realities. The perspective-taking approach views the forms of grammar as emerging from repeated acts of perspective-taking and perspective-switching. Grammatical devices such as pronouns, case, voice, and attachment can all be seen as ways of expressing shifts in a basically ego-centered perspective. One major goal in this new line of research is to better understand the brain mechanisms underlying perspective-shifting.
