Researchers at the University of Tsukuba in Japan published a paper in the cognition that found that the perception of pain may be affected by factors such as pain and beliefs about its uncertainty. This means that when taken from surprise, your brain can increase the pain caused by injury.
Expectations affect pain
The study conducted research on an event called Baysian Aquarius, which explains how our brain processes the pain differently when reality does not match our expectations -it is related to how the same injury can hurt us differently or how the pain is different from a person.
the study
The study found that the perception of pain depends on our expectations and is sure about what we are coming. He used two virtual reality experiments with 23 participants and used heat stimulation.
In the first experiment, the participants had to control a virtual knife with their left hand and stabbed it in their virtual right forearm, while a device applied heat in their real hand at different times – either with a virtual knife or about a second. The knife visible during the test or disappeared just before contact.
In the second experiment, 26 participants observed the movement of a knife without controlling themselves, allowing researchers to investigate how the spirit of control affects the perception of pain.
conclusion
Researchers found that the intensity of pain was quite high when it delayed heat stimulation when it was together with the knife contact. This effect was stronger when the knife suddenly disappeared. These effects only appeared in the group that controlled the knife themselves, not those who only saw it.
Conclusions suggest that pain perception operates on the principles different from other sensory experiences. Pain is mainly experienced due to prediction errors or surprises.
