Passage One
Questions 46 to 50 are based on the following passage.
“The dangerous thing about lying is people don't understand how the act changes us.” says Dan Ariely behavioural psychologist at Duke University. Psychologists have documented children lying as early as the age of two. Some experts even consider lying a developmental milestone, like crawling and walking, because it requires sophisticated planning, attention and the ability to see a situation from someone else’s perspective to manipulate then. But, for most people, lying gets limited as we develop a sense of morality and the ability to self-regulate. Harvard cognitive neuroscientist Joshua Greene says, for most of us, lying takes work. In studies, he gave subjects a chance to deceive for monetary gain while examining their brains in a functional MRI machine, which maps blood flow to active parts of the brain. Some people told the truth instantly and instinctively. But others opted to lie, and they showed increased activity in their frontal parietal (颅腔壁的) control network, which is involved in difficult or complex thinking. This suggests that they were deciding between truth and dishonesty—and ultimately opting for the letter. For a follow-up analysis, he found that people whose neural (神经的) reward centers were more active when they won money were also more likely to be among the group of liars – suggesting that lying may have to do with the inability to resist temptation. External conditions also matter in terms of when and how often we lie. We are more likely to lie, when we are able to rationalise it, when we are stressed and fatigued or see others being dishonest. And we are less likely to lie when we have moral reminders or when we think others are watching. “We as a society need to understand that, when we don’t punish lying, we increase the probability it will happen again.” Ariely says. In a 2016 study published in the journal Nature Neuroscience, Ariely and colleagues showed how dishonesty alters people’s brains, making it easier to tell ties in the future. When people uttered a falsehood, the scientists notice a burst of activity in their amygdala. The amygdala is crucial part of the brain that produces fear, anxiety and emotional responses— including that sinking, guilty feeling you get when you lie. But when scientists had their subjects play a game in which they won money by deceiving their partner, they noticed the negative signals from the amygdala began to decrease. Not only that, but when people faced no consequences for dishonesty, their falsehood tended to get even more sensational. This means that if you give people multiple opportunities to lie for their own benefit, they start with little lies which get bigger over time.
