Scientists have explained the cause of human error

Until now it was assumed that people make mistakes or referring own narrow-mindedness, or because of certain failures of the brain. However, the new study found that the wrong person is forced to act extraneous "noise" flawed information pouring a continuous stream of his brain.

Researchers from Princeton University (USA), found that process information the human brain is capable of when it comes to it properly, and when the brain receives erroneous information or the so-called "noise", he begins to fight a certain way.

Neuroscientists have long puzzled over the question of whether a bad decision to become a consequence of incorrect entry of any information or the brain during the synthesis of this information makes mistakes. Measurements of brain neurons, with earlier studies have shown that the brain is, in fact, working on the sound effect.

New research has allowed scientists to determine that even if the information is quite fragmented and loud at the thought process is not affected, he takes a measured and surprisingly quiet. The study included the participation of four volunteers and 129 laboratory rats who listened to a stream of random clicks sounds. Then they had to indicate which side occurred more audio streams. In the end, it turned out that the sound was more difficult to identify when they are overlapped by background noise.
