| 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.
