Did your “stress genes” affect on your SAT scores?

 

This is an article that I read a while ago which described the effects of COMT gene and its function in clearing dopamine in the brain that is often released as a result of a stress response. There are two variants of the COMT gene: one which clears dopamine at a faster rate and another one which is a slower acting version. Usually, people with the slow variant do better on cognitive tests in the laboratory. However, under surges of stress, such as high-stake tests, when the brain is flooded with dopamine, researchers found that those with the slower variant were at a disadvantage. In Taiwanese national exams, students with the slow variant scored an average of 8 percents lower. “It was as if some of the A students and B students traded places at test time.”
What do you think about the influence of stress on your performance in school and other tests. Personally, I would love to know my COMT polymorphism in addition to ACTN gene. New genetics lab @ rafakoko?
