                                           Decision-making under Stress

     A new review based on a research shows that stress affects the way the brain considers

the advantages and disadvantages, causing it to focus on pleasure and ignore the possible

negativeconsequences(results) of a decision.

     The research suggests that stress may change the way people make choices.

     "Stress affects how people learn," says Professor Mara Mather. "People learn better

about positive than negative outcomes under stress."

     For example, two recent studies looked at how people learned to connect images with

either rewards or punishments. In one experiment, some of the participants were first

stressed by having to give a speech and do difficult math problems in front of an audience;

in the other, some were stressed by having to keep their hands in ice water. In both cases,

the stressed participants remembered the rewarded material more accurately(精确) and

the punished material less accurately than those who hadn't gone through the stress.

     This phenomenon is likely not surprising to anyone who has tried to resist eating cookies

or smoking a cigarette while under stress -at those moments, only the pleasure associated

with such activities comes to mind. But the findings further suggest that stress may bring

about a double effect. Not only are rewarding experiences remembered better, but negative

consequences are also easily recalled.

     The research also found that stress appears to affect decision-making differently in men

and women. While both men and women tend to focus on rewards and less on consequences

under stress, their responses to risk turn out to be different.

     Men who had been stressed by the cold-water task tended to take more risks in the

experiment while women responded in the opposite way. In stressful situations in which

risk-taking can pay off big, men may tend to do better, when caution weighs more,

however, women will win.

     This tendency to slow down and become more cautious when decisions are risky might

also help explain why women are less likely to become addicted than men: they may more

often avoid making the risky choices that eventually harden into addiction.
