Can a dream help eyewitnesses remember the face of a criminal?

More recently, scientists from the US stateMichigan found that in the allergy season, between the beginning of spring and the end of autumn, the least crimes are committed in cities. This is due to the fact that the painful condition affects not only ordinary people, but also potential criminals, who, due to a breakdown, are simply not able to harm others. However, for the rest of the time, crimes are still committed and the police need to find and arrest their participants as soon as possible. In this case, eyewitnesses of the incidents help them a lot, but many of them sometimes cannot accurately remember the appearance of violators of the order. Scientists have long known that a dream helps restore memory, so what does it do - if eyewitnesses get a good night's sleep before the process of identifying a criminal, will they quickly remember his face?

Shot from the movie “Suspicious Faces”

To find out, scientists from the USA andThe United Kingdom conducted a study whose results were published in the scientific publication Medical Xpress. The scientific work was attended by 4,000 volunteers who were shown a video with a fake crime. They were given the task to carefully watch the video, remember the signs of the offender and recognize him in a special room with several suspects.

Does sleep improve memory?

Only now the recognition process was carried out indifferent time. The participants were divided into three groups, where people from the first were given the opportunity to sleep at night. The second group of people was forbidden to sleep during the day before the process of identifying a criminal. But the rest of the participants entered the room with the suspects immediately after watching the video of the crime. According to researchers, sleepy people should have pointed to a real criminal much faster than others, but their expectations were destroyed.

The dream is really useful, but not in order to better remember the face of the criminal

As it turned out, almost all eyewitnesses are excellentcoped with the task and remembered the special signs of the person who committed the crime. It turns out that the absence and sleep had practically no effect on the memory of the witnesses, and they recognized that the person needed was equally quickly. From this, the researchers concluded that although a dream can improve a person’s memory, it does not affect the ability of witnesses to remember violators of the law.

Recently, scientists have found that sleep helps the brain forget unnecessary memories.

However, the results of the study cansubject to great doubt. The fact is that there is a big difference between watching a crime video in a comfortable chair and watching a murder in real conditions. If a person actually becomes an eyewitness to some terrible event, he may panic and he will not remember anything. In this matter, even a sound sleep is unlikely to help him. Perhaps eyewitnesses to crimes will not be able to fall asleep after what they experienced.

Nevertheless, scientists are sure that their scientificwork should help the cops. In their opinion, the results of their research should be kept in mind during any legal proceedings. It is very likely that if the witness is sure that his choice is correct, then the suspect is really the culprit, regardless of whether the eyewitness slept before the process of identifying him or not.
