A study reveals that the brain areas that respond when fear is learned through personal experience are al-so triggered when we see someone else in distress.
In the study, participants watched a short video of a person conditioned to fear a so-called neutral stimulus-something people normally wouldn't fear--paired with something they find naturally aversive (令人讨厌的), in this case an electrical shock. The person in the video watched colored squares on a computer screen: When a blue square appeared, the person received a mild shock; when a yellow square appeared, there was no shock. The participant in the video responded with distress when the blue square appeared—he would blink hard, tense his cheek muscles and move his hand. "So it's clear that he's uncomfortable, he's in distress," said study team member Andreas Olsson of Columbia University. "And he's already in distress before he receives the shock, you see him anticipate receiving the shock." By contrast the participant in the video appeared relaxed when the yellow square popped up,
Participants were told they would take part in a similar experiment, and when presented with the blue square, they responded with fear, anticipating a shock, though they were never actually shocked. "Just by watching, they learn themselves," Olsson explained.
This second learning was reflected in the brain. In previous classical conditioning experiments where a fear is learned firsthand, a part of the brain called the amygdala (扁桃核) has been shown to be critical to the development and expression of fears. The scientists monitored the brain activity of each participant during the experiment. Imaging showed that the amygdala responded both when the subjects watched the video of someone else receiving shocks and when they were presented with the blue squares themselves.
"We found that the amygdala is involved both when you're watching somebody receiving shocks, and when you're expecting to receive shocks later on yourself," Olsson said. So it seems that similar processes in the brain are triggered both when fears are experienced first-hand and when they are observed in others.
In the real world, the finding could explain why some people are afraid of things despite little contact with them. "You learn by observing other people's emotional expressions, and what we are showing is that that can be as effective as having those direct experiences yourself," Olsson said. "That's probably one of the reasons why a lot people are having phobias (恐怖症) of certain kinds of stimuli, such as snakes and spiders."

Many women who battle breast cancer will tell you it's a life-changing experience. However, a new study shows that for many (51) , the changes aren't always positive or permanent.
Beth Snoke has watched her mother and both grandmothers battle and survive breast (52) So when she was diagnosed, there was no doubt in her mind (53) she had to do.
"I do exactly what the doctors say as far as the medicine that I'm on, as (54) as the vitamins, the diet, and the fitness. And I can't stress enough (55) important that is," says Beth Snoke. But a surprising new study shows that (56) every woman who beats breast cancer is getting that message. In fact, nearly 40% of them say even (57) surviving breast cancer, they haven't made significant changes in the (58) they eat or how much they exercise.
"Not all survivors are taking advantage of this teachable moment and making positive health changes in (59) life," says Electra Paskett, PhD, at Ohio State University's Comprehensive Cancer Center. Paskett says diet and exercise have been proven to not only help women feel better during and after treatment, they may (60) play a role in preventing some cancers from coming back (61) growing evidence, some women just aren't listening.
"Colon cancer survivors (62) exercise have actually been shown to have improved survival rates. So, yes, it is true that perhaps by making some of these healthy choices we can actually increase their health," says Paskett.
As a breast cancer survivor (63) , Paskett knows first hand how much difference diet and exercise can (64) The challenge, she says, is to get more survivors to be more like Beth, during and after treatment.
Experts say exercising more and eating a healthier diet can also cut (65) on stress and help women overcome depression. There are more than 2 million breast cancer survivors living in the U.S. Of those, nearly a million have yet to change their diet or exercise routines.
