Alcohol doesn’t make people behave badly

Unless you are teetotal, we've all had a morning after when we are forced to wonder why on earth we did that hugely embarrassing thing while drunk the previous night.

This sends an alarm signal to other parts of the brain indicating that something went wrong. Our study shows that alcohol doesn't reduce your awareness of mistakes - it reduces how much you care about making those mistakes.

During the study, Prof Bartholow's team of psychologists measured the brain activity of people aged between 21 and 35 as they completed a tricky computer task.

One third of them were given alcoholic drinks, while the rest were given no alcohol.

In addition to monitoring their brain activity, the researchers also measured changes in participants' mood, their accuracy in the computer task and their perceived accuracy.

However, they were no less likely to realize when they had made a mistake - they just didn't care as much.

"In certain circumstances reducing the brain's alarm signal could be seen as a good thing, because some people, like those with anxiety disorders, are hyper-sensitive to things going wrong. In some people, a small amount of alcohol can take the edge off those anxious feelings," added Prof Bartholow.
