Daytime sleep helps the brain process subconscious information

It is unlikely that anyone will deny the value of the afternoon siesta, but soon this habit may become the basis of the modern educational process. Research by scientists at the University of Bristol (UK) has shown the importance of short periods of nap for processing and memorizing complex arrays of new information. We are talking about the area of ​​unconscious processes that cannot be controlled at will.

The experimental students were given a double task to test the neural response - the main one and the additional one. In the basic task, it was just necessary to respond correctly and in a timely manner to the inclusion of blue and red light bulbs. The additional test was tricky. First, the first word was displayed on the screen for only 30-40 milliseconds, then the XXXXX mask for 0.5 seconds and then the second word for a whole second. The words could have a logical war-peace connection or not, and the students had to react to the correct options.

The idea is that the first word is impossible to read and understand, but it triggers a neural response. And if the words in a pair are connected, then the understanding of this, the reaction of a person, comes faster than for disparate options. In spite of their desire, the students could not influence the word recognition process in any way, but then the control group was allowed to sleep for 90 minutes. And as the tests continued, the rate of their neural responses increased, although the number of errors remained the same. The indicators for the main task were identical for all students.

Scientists conclude that when the brain is tasked with solving issues where it is impossible to apply deliberate methods, it runs into a dead end. But if you let the body sleep, then a certain mechanism is activated that allows you to transfer the load to subconscious thinking. This does not guarantee victory and successful achievement of the original goal, but the very fact of switching the brain into a certain new mode intrigued scientists very much and they intend to continue working in this direction.
