A study by Kio University found that given linguistic information that causes fear, the subjective feeling of physical possession increases even for fake hands, and the greater the degree of increase, the more likely it is to feel pain. rice field.

 It has been clarified that a decrease in the sense of ownership hinders the rehabilitation effect by making one's body not feel as one's own.However, the effects of top-down factors such as context (linguistic information) on physical ownership have been sufficiently verified compared to bottom-up factors such as visual sense, tactile sensation, and proprioception (location information). I didn't.

 In this research, we use an illusion phenomenon called "rubber hand illusion" to make participants think that the fake arm with a nail is their own hand and evoke a sense of physical possession. We examined how the presence or absence affects it. Under the condition of "with fear context", the background of the arm where the nail is stuck is explained to cause fear such as "the nail penetrates, bleeds, and there is severe pain", and under the condition of "without fear context", the explanation is given. "While preparing for the costume party, there is no pain at all with fake nails and blood glue," he explained without causing fear.

 As a result, it is clear that when linguistic information that causes a fear context is presented, subjective physical ownership increases, and participants with a greater degree of increase are more likely to feel pain (lower the pain threshold). It is said that it became.

 This indicates that linguistic information is one of the factors involved in physical ownership and pain, and linguistic information such as explanations of pathological conditions given by medical professionals may also affect physical ownership and pain. Was suggested.The number of participants in this experiment was 30 healthy people, but it has been reported that those with physical and mental distress have a reduced sense of physical possession.Therefore, it is necessary to verify the difference between healthy people and people with chronic pain in the future.
