Manipulating brain activity to boost confidence | EurekAlert! Science News

"Surprisingly, by continuously pairing the occurrence of the highly confident state with a reward - a small amount of money - in real-time, we were able to do just that: when participants had to rate their confidence in the perceptual task at the end of the training, their were consistently more confident".
