Two participants put on headsets, and first look down at their laps, so that they see their partner’s body instead of their own. They then make a series of coordinated movements, following detailed instructions, and if they follow along closely enough, their new body will appear to respond to their commands, strengthening the experience of being the other. After some time, mirrors are held up, and each sees the mirror image of the other, as if it were himself or herself.
