Your pessimism could be fault of genes

The people who for years have been held pessimistic, negative or having the ability to see the black spot in the middle of the white universe could not to blame.

That is the conclusion reached by a team of scientists that were part Rebecca Todd, University of British Columbia (Canada), and Adam Anderson, Cornell University (United States).
The research found that due to a variation of a gene, some people may perceive more intensely than other negative events, and, likewise, be influenced in the way as perceived, and therefore, live and experience the world.
'Almond' of the matter, says the research, is in the deleted variant of the ADRA2b gene, which complies with a starring role in the formation of emotional memories - according to previous studies and the research-on the perception of the real time.
Scientific work, whose results were published by the journal Psychological Science, involved 200 individuals, who were in direct contact in successive and fast way with positive, negative and neutral words. Individuals with the genetic difference ADRA2b were more likely to perceive and to retain the negative words.
However, it caught the attention of scholars that both groups showed more affinity with the positive words that with neutral words.
Thus, says Professor Todd, "people with the genetic difference were more likely to see and identify faces in a crowd of people angry. "Also, it may be more perceptive to establish potential hazards in the environment, such as dangerous rocks or smooth floors, more than the beauty of the environment".
'There is a gene of negativity'
However the discovery, some scientists unbelievers showed. 'There is a gene for negativity nor will it in the future,' wrote the neuroscientist Ahmad R. Hariri, of Duke University, to be interrogated about the research by The Washington Post. He believes that, instead, thousands of genes and their variations are thousands of possibilities that, by interacting with the environment, are gradually forming behaviors.
