Mel Slater of the University of Barcelona in Spain and colleagues put 30 people in a virtual reality (VR) environment in the body of a 4-year-old child or a scaled-down adult the same height as the child. The virtual body, which moved in sync with movements of the real body, could be viewed from a first-person perspective and in a mirror in the VR environment. ...
Prior research by Slater's team shows that when a person acquires a body type they have never experienced, social and cultural expectations often influence how they relate to the new body.
Things we experience in a virtual landscape can also have profound effects on our behaviour in the real world: in a separate study by researchers at Stanford University in California, giving people superhero powers in a virtual environment made them behave in a more helpful manner in real life.
The researchers say that brain imaging studies would help them to understand the reorganisation that occurs when assimilating a new body. The motivation springs from a project looking at how to embody people in child-sized robots. "We thought we ought to look at the consequences of that first," says Slater.
