John Pavlus writes on io9.com:
Science fiction has long played with the idea of projecting unified personalities/minds/”souls” into different bodies. The premise is baked into the plots of stories like Avatar and Caprica. But how would it work in the real world?
That’s what the science of “embodied cognition” is all about. The basic idea in this new(ish) research area (which overlaps with cognitive psychology, neuroscience, artificial intelligence, robotics, and others) is this: Your mind is defined by your physical form. Not just in terms of “the mind is what the brain does”-we all are pretty down with that already. This takes it further to encompass the whole enchilada: your mind-your “I”-is a function of a cephalized, bipedal, plantigrade, bilaterally symmetrical body between 1.5 and 2 meters tall with two arms terminating in five-fingered hands with opposable thumbs, two lungs, a warm-blooded vascular system, mostly hairless skin, two front-focused eyes, etc.
