Researchers at the Max Planck Institute for Human Cognitive and Brain Sciences in Leipzig, Germany have found a genetic factor that affects our ability to learn from our errors. The scientists demonstrated that men carrying the A1 mutation, which reduces the amount of dopamine D2 receptors in the brain, are less successful at learning to avoid mistakes than men who do not carry this genetic mutation. This finding has the potential to improve our understanding of the causes of addictive and compulsive behaviors.
