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."

A．Normally they are not scared by it.
B．Usually they are seriously scared by it.
C．They feel ridiculous when seeing it.
D．They often feel uncomfortable at it.

Is it difficult for you to get up in the morning？ Do you sometimes oversleep？ Are you often late for work or school？ Yes？ Then Hiroyuki Sugiyama of Japan has a special bed for you. Hiroyuki’s bed
188. Is it difficult for you to get up in the morning？ Do you sometimes oversleep？ Are you often late for work or school？ Yes？ Then Hiroyuki Sugiyama of Japan has a special bed for you. Hiroyuki’s bed will get you up in the morning! Here is how it works: The bed is connected to an alarm clock. First, the alarm clock rings. You have a few minutes to wake up. Next, a tape recorder in the bed plays soft music or other pleasant sounds. A few minutes later, a second recording plays. The second recording can be loud music or unpleasant sounds. If you don’t get up after the second recording, you’ll be sorry. A mechanical “foot” is in the bed. The mechanical foot kicks you in the head. Then the bed waits a few more minutes. What! You’re still in bed! Slowly, the top of the bed rises higher and higher. The foot of the bed goes lower and lower. Finally, the bed is vertical. You slide off the bed and onto the floor. You are awake and out of bed. Hiroyuki made his bed because he wanted to win a contest. He works for Honda Motor Company. Once every two years, Honda has a contest—the “All Honda Idea Contest”. In 1996 Hiroyuki won a prize for his bed. [共5题]
