A new research project in Sweden is delivering great insights in how we become identified with our body and personality.
How do we form our identity? We enter this world totally clean and clear of any definitions of who we think we are. Then we start learning what we can control relatively easily (arms, legs) and what we can’t (other people, things).
In the pursuit of enlightenment, you start to question the limitations of who you are. Yogis and mystics spend lifetimes in meditation and tell us we are much more than we think we are. Some hint that we are God, or the Tao, or one with the Absolute Reality. But it’s hard to appreciate this when you are cramming a toastie into your mouth and running out the door to try to make the bus to work.
It intrigues me to watch kids playing computer games. They get so involved. They take it personally when the Super Mario character that they are operating gets killed. They don’t say, “Oh no, Mario got killed”… instead they say, “Nuts! I got killed!” and they flop down in desperate annoyance. What’s that about?
That’s the power of identification.
Have you played on a computer game? It’s not just children that become identified with the avatar character they are operating, is it? We all do.
It may be a fuzzy logic conclusion to make, but it’s hard not to look at that process and wonder if the same thing goes on with this human life we are living. Are we actually a vast consciousness, unlimted, free, that plays this human game and becomes temporarily identified with the avatar character (you, your life)?
The research in Sweden adds another dimension of fact to this observation of the ease with which we become identified with something that we can control…

Swedish Scientists Trick People Into Thinking They’ve Swapped Bodies

STOCKHOLM, Sweden - Shaking hands with yourself is an amusing out-of-body experience. The illusion of having your stomach slashed with a kitchen knife, not so much. Both sensations, however, felt real to most participants in a Swedish science project exploring how people can be tricked into the false perception of owning another body.
In a study presented Tuesday, neuroscientists at Stockholm’s renowned Karolinska Institute show how they got volunteers wearing virtual reality goggles to experience the illusion of swapping bodies with a mannequin and a real person.
“We were interested in a classical question that philosophers and psychologists have discussed for centuries: why we feel that the self is in our bodies,” project leader Henrik Ehrsson said. “To study this scientifically we’ve used tricks, perceptual illusions.”
It sounded intriguing enough for me to try it, though entering the laboratory on Monday, I was having second thoughts.
The first props I saw were two kitchen knives, three naked dummies and a prosthetic hand sticking out from behind a curtain.
“You have the right to say stop at anytime if you feel uncomfortable,” said Ehrsson’s colleague, Valeria Petkova, as she rubbed my left hand with electrolytic gel and attached electrodes to the middle and index fingers.
She assured me I was not in any danger. Still, a nervous tingle rushed through my body as she placed the headset over my eyes.
In the first experiment, the goggles were hooked up to CCTV cameras fitted to the head of a male mannequin, staring down at its feet. Through the headset I saw a grainy image of the dummy’s plastic torso. I tilted my head down to create the sensation I was looking down at my own body.
At that point, it didn’t feel very real. But when Petkova simultaneously brushed markers against my belly and that of the mannequin, the effect started setting in. As my brain processed the visual and tactile signals, I had a growing impression that the mannequin’s body was my own.
That was good fun, until the gleaming blade of a bread knife entered my field of vision. Petkova slid it across the dummy’s stomach, sending shivers down my spine and a pulse of anxiety through the electrodes. My heightened stress level was illustrated by a spike in a computer diagram shown to me after the experiment.
“Approximately 70-80 percent of the people experience the illusion very strongly,” Petkova said.
Apparently, I was one of them.
The second experiment was more benign. This time my headset was connected to cameras mounted on a round hat that Petkova was wearing. We faced each other, extended our right arms and shook hands.
Now that was weird: I was supposed to have the sensation of shaking hands with myself. The illusion wasn’t perfect as I couldn’t quite recognize Petkova’s grip as my own, even though that’s what the goggles meant to make me believe.
Perhaps the session was too short. The actual study, in which 87 volunteers participated, consisted of repeated sessions that gradually provided more accurate data. The results were published in PLoS One, the online journal of the Public Library of Science.
The principle finding was that under certain conditions a person can perceive another body as his or her own, even if it is of an opposite gender or an artificial body.
“These findings are of fundamental importance because they identify the perceptual processes that make us feel that we own our entire body,” the study said.
Ehrsson said the study built on a previous experiment known as the “rubber hand illusion” in which participants were manipulated to experience a rubber hand as their own.
Charles Spence, a professor of experimental psychology at the University of Oxford, said the Karolinska study was a “step up” from other research on the subject.
“This goes beyond other recent studies, where you’ve taken ownership of rubber hands and rubber legs,” said Spence, who was not involved with the study.
His only concern was whether there might be any lasting effect on participants.
“The questions is what happens if you did it much longer? If you were in there for days and weeks. Would it be like something out of Total Recall?” Spence said, referring to the 1990 Arnold Schwarzenegger science fiction movie about a virtual vacation that turns into a nightmare.
Ehrsson suggested the findings could be applied in research on body image disorders by exploring how people become satisfied or dissatisfied with their bodies. Another possible application could be developing more advanced versions of computer games such as Second Life, he said.
“It could lead to the next generation of virtual reality applications in games, where people have the full-blown experience of being the avatar,” Ehrsson said.
Fascinating, isn’t it? Next time you are caught up in your problems, pull back and think about what you are identifying with. Is it just a game? Are you much more than you think you are?
Be big…
I twittered the other day about a great piece of writing I had just read by Kevin Hogan and wanted to follow up by blogging about it, and giving it a permanent “high-five!” on my site.
