Researchers from the University of Wisconsin-Madison argued that self-talk is a normal phenomenon, not a mental illness. After much research it was concluded that talking with you is very useful for the brain.
The proof of the correctness of the conclusions of the scientists was a simple experiment, conducted with the participation of two groups of volunteers. Test subjects from the first group were asked to find in the room of hidden things, commenting on their actions. People from the second group had to search for hidden things in silence. The results were amazing group of people speaking during the search, coped with the task and found the hidden things much faster "undecideds".
Psychologists explain this fact is that it stimulates thinking and accelerates the brain, suggesting the right solutions.
