Virtual Superpowers

Researchers at Stanford recently investigated the subject by giving people the ability of Superman-like flight in the university's Virtual Human Interaction Laboratory (VHIL). While several studies have shown that playing violent videogames can encourage aggressive behavior, the new research suggests that games could be designed to train people to be more empathetic in the real world. To test this hypothesis, the group needed to choose a superhuman ability that could only be simulated in virtual reality, but that people would also subconsciously identify as a ‘do-gooder’ superpower. One at a time, 30 men and 30 women entered the simulator and strapped on a set of goggles that transported them into a digital cityscape. A woman's voice then explained their mission: A diabetic child is stranded somewhere in the city, and you must find him and deliver an insulin injection.


With a whoosh of air, the subjects left the ground -- either controlling their flight by a series of arm motions, like Superman, or as a passenger in a helicopter. As they scoured the city, wall-mounted speakers gave the impression of wind whistling by; powerful speakers in the floor produced vibrations to simulate riding in a helicopter. The experiment was set so that two minutes into the simulation, no matter what mode of transport, the subject found the sick child. After removing the virtual reality goggles, each person then sat with an experimenter to answer a few questions about the experience.  The people who had just flown as Superman were quick to lend a hand, beginning to pick up the pens within three seconds. The helicopter group, however, picked up the first pen, on average, after six seconds (one second after the experimenter began picking them up herself).
