Scientists identify “ Happiness Gene ”
If life looks joyful in spite of recession (经济衰退) ，job insecurity and expanding waistline, then you should consider thanking your “brightside ” gene.
A gene that affects if we’re cheery or gloomy has been tracked down by British researchers, reports The Guardian.
The groundbreaking study claims that individuals who carry the gene don’t pay much attention to negative things happening in their lives and, instead, focus on the happier aspects of life. In the process, they end up becoming more sociable and are generally in better shape psychologically.
Elaine Fox, head of psychology at Essex University, said: “ We’ve shown for the first time that a genetic variation is linked with a tendency to look on the bright side of life. This is a key mechanism underlying resilience (复原力) to general life stress. ”
To reach the conclusion, the research team checked how long it took people to react to good and bad images that flashed up on a computer screen. The study involved more than 100 volunteers.
The positive snaps were that of a couple hugging and someone sailing along in a boat. The negative images included a photo of someone being mugged(抢劫).
Every individual inherits(继承) two versions of the gene, either two short ones, two long ones , or one of each. People who had two long versions were most likely to focus on the positives, according to the study published in Proceedings of the Royal Society B(《皇家学会学报B》) .
