( Psychologists from the University of Ex...)Brain Signal Prevents Us from Repeating Mistakes,Health

Psychologists from the University of Exeter have identified an 'early warning signal' in the brain that helps us avoid repeating previous mistakes. Their research identifies, for the first time, a mechanism in the brain that reacts in just 0.1 seconds to things that have resulted in us making errors in the past.

Previous research has shown that we learn more about things for which we initially make incorrect predictions than for things for which our initial predictions are correct. The element of surprise in discovering we are wrong is conducive to learning, but this research is the first to show how amazingly rapid our brains response can be.

This discovery was made possible through the use of electrophysiological recordings, which allow researchers to detect processes in the brain at the instant they occur.

'It's a bit of a clich to say that we learn more from our mistakes than our successes,' said psychologist Professor Andy Wills of the University of Exeter, 'but for the first time weve established just how quickly the brain works to help us avoid repeating errors. By monitoring activity in the brain as it occurs, we were able to identify the moment at which this mechanism kicks in.

For this study, a group of volunteers took part in a computerised task, which involved them making predictions based on information they were given. New information was then introduced, which made many of their predictions incorrect, so they needed to learn from this in order to avoid repeating the error.

While they did this, their brain activity was recorded via 58 electrodes placed on their scalp. The researchers identified activity in the lower temporal region of the brain, the area closest to the temples. This occurred almost immediately after the person was presented with the visual object that had previously made them make an error, and before there was time for conscious consideration.
