Many of us sometimes catch ourselves thinking that all this has already happened before. This phenomenon is called deja vu, and the reason for its occurrence is quite prosaic.
A research group at Colorado State University decided to test a hypothesis that arose about a hundred years ago. According to her, déjà vu occurs when a person finds himself in a situation similar to the one in which he was once in the past. The limbic system of the human brain, which is responsible for memories, reacts to this trigger, but also attributes circumstances that could not have happened in the past.
The most common triggers of this phenomenon are spatial or auditory impressions. That is, déjà vu is most likely to occur when a person finds himself in a situation similar to the one seen in the past or becomes a participant in a conversation similar to the one in which he once participated.
This hypothesis was recently tested using virtual reality. And she finally got confirmation.
The researchers placed a group of subjects in different scenes, changing the arrangement of elements in it. Scientists were able to induce deja vu in those cases where the scenes were similar to those seen by the study participants before.
Thus, American scientists were able to confirm the old theory of the connection between deja vu and spatial structure. They note that the familiar environment is probably not the only cause of the phenomenon, and they hope to continue the research in the future.
