Gambling is a genetically determined love it

Why are some people addicted to gambling by nature? And how eager some people do not? A recent study found that because the brain's "fear center" of gambling respond, people worry about losing money, do not want to gamble; area impaired the brain, becomes afraid of losing money and dare to gamble. This is why most people turn away from gambling, and why some people addicted to gambling?

Experimental bet

California Institute of Technology academics benedetto Todd Martino and his colleagues want to know why people may give up the case of gambling winnings.

The team brought in 14 volunteers. Two female volunteers with the gene associated with Wu - Wei's disease. Their brain amygdala damage due to this rare disease, but normal in other regions. Another 12 volunteers completely normal brain, divided into two groups and the two women were in control.

Faced with a series of gambling test, damage to the amygdala as a control group of women with very different reactions of ordinary people.

When the amount of money could win the money to be 1.5 times to lose twice, the common people love to gamble. When the 50% probability of winning or losing, the ordinary people most likely to accept or lose $ 5 or 20 dollars to win the bet, most tend to reject or lose 20 dollars, or win $ 20 bet.

The two women apparently damaged amygdala more than the control group do not worry about losing money. Even if it may be possible to win less money to lose money, they are also willing to bet.

8 of their report published in the United States, "National Academy of Sciences."

Cautious "switch"

Reported that the experiment shows that the amygdala and related psychological fear of losing money gambling. Amygdala is located in the front temporal lobe, almond shaped, and the brain processes fear and other emotions and memory.

De Martino, is now a visiting scholar at University College London. He and Ella and Ralph Caramel scholar Colin Graves Adolph co-authored the study.

Caramel Ella said: "This research shows that gambling amygdala triggers 'may lose money' sense of critical care."

"Give full play to the role of the amygdala, it seems to make us more cautious," Adolf Adams said, "We already know that fear of the amygdala and related processing; now that it seems to make us 'fear' losing money."

The report said: "From the laboratory and field survey evidence that people often unwilling to bear the 'loss' of the risk, even though it may win more."

The team called this phenomenon the "rejection losses." They, for example: "When (the brain normal) people face or lose 10 dollars or 15 dollars to win the bet, if the 50% probability of winning or losing, they will give up gambling."

"Bold" chase for

The team hope that this study helps to analyze the people in the political, economic and other areas of how decision-making.

De Martino said: "The amygdala may be a very general biological control mechanisms. When a behavior may lead to negative consequences, this mechanism will inhibit the people to do this risky thing. For example, the loss of money worried about the impact of our daily financial decisions. "

The team said the study also could help further the academic study of why some people are more willing than others to take risks. Perhaps these people with different genes involved in amygdala.

Cardiff University psychology professor John Agnes Layton said that most people are worried, "loss", "and this study clearly shows that when the amygdala is damaged, this 'rejection loss' disappear."
