Ever wonder what it’s like to be in the body of another person, psychologically speaking? Sure! Well, now scientists in Sweden have created that feeling in a couple of experiments:
In a first experiment, they fitted the head of a shop dummy with two cameras connected to two small screens placed in front of the subjects’ eyes, so that they saw what the dummy “saw.” When the dummy’s camera eyes and a subject’s head were directed downwards, the subject saw the dummy’s body where he or she would normally have seen his or her own.
The body-swapping illusion arose, investigators said, when a scientist touched the stomach of both with two sticks. The subject could then see that the mannequin’s stomach was being touched while feeling, but not seeing, a similar sensation on his or her own stomach. As a result, the subject developed a powerful sensation that the mannequin’s body was his or her own, researchers said.
In another experiment, the camera was mounted onto another person’s head. When this person and the subject turned towards each other to shake hands, the subject perceived the camera-wearer’s body as his or her own.
