How We Learn from Our Mistakes

really? I find it hard to believe this.

“Everyone can learn from their mistakes — but some people have genes that may make it harder. That’s the message from German researchers, writing in tomorrow’s issue of the journal Science, who have shown how a common gene variant affects some people’s ability to respond to, and learn from, the negative repercussions of their actions.

In a small study, the researchers scanned the brains of 26 men as they each performed a simple task: choosing one symbol from a pair of symbols. After each selection, the participant was presented with a smiley face or sad face, depending on the symbol he had chosen. All men were equally good at learning to pick the symbols that won them a smiley face, but some men were worse than others at avoiding the ones that resulted in sad faces. Those men, it turns out, had a particular gene variant, or allele, that reduces the density of receptors for dopamine — a neurotransmitter that plays a key role in motivation, pleasure and addiction — in certain areas of the brain. Brain scans also showed significantly less activity in those areas in response to the sad-faced negative feedback, in the men who had the allele. When it occurred, however, that brain activity was linked to activity in other parts of the brain that forms memories.

It’s the first strong physiological evidence that the density of dopamine receptors may affect how people respond to negative inputs. Previous studies have established a strong link between a low density of dopamine receptors and addiction, obesity and compulsive gambling — conditions that suggest an impaired ability to learn from the consequences of bad decisions…”
