Article: Sensing phantom phone vibrations is a strangely common experience. Around 80% of us have imagined a phone vibrating in our pockets when it's actually completely still. Almost 30% of us have also heard non-existent ringing. Are these signs of madness caused by digital culture? Not at all. In fact, phantom vibrations and ringing indicate a fundamental principle in psychology. Psychologists use a concept called Signal Detection Theory to guide their thinking about the problem of perceptual judgments. Working through the example of phone vibrations, we can see how this theory explains why they are a common and unavoidable part of healthy mental function. When your phone is in your pocket, the world is in one of two possible states: the phone is either ringing or not. You also have two possible states of mind: the judgment that the phone is ringing, or the judgment that it isn't. Obviously you'd like to match these states in the correct way. True vibrations should go with "it's ringing", and no vibrations should go with "it's not ringing". Signal detection theory calls these faithful matches a "hit" and a "correct rejection" But there are two other possible combinations: you could mismatch true vibrations with "it's not ringing" (a "miss"); or mismatch the absence of vibrations with "it's ringing" (a "false alarm"). This second kind of mismatch is what's going on when you imagine a phantom phone vibration. What does that mean in terms of your phone? We can assume that people like to notice when their phone is ringing, and that most people hate missing a call. This means their perceptual systems have adjusted their bias to a level that makes misses unlikely. The unavoidable cost is a raised likelihood of false alarms of phantom phone vibrations. The trade-off between false alarms and misses also explains why we all have to put up with fire alarms going off when there isn't a fire. It isn't that the alarms are badly designed, but rather that they are very sensible to smoke and heat and biased to avoid missing a... Question: When we judge correctly that "it's not ringing", this is called a "_". Yes or no, is the answer "correct rejection"?
No

Article: A few years ago,my friend Al won the lottery. It changed his life. He did not have a rich family. He was not born with a silver spoon in his mouth. Instead,my friend was always hard up for cash. He did not have much money. And the money he did earn was chicken feed -- very little. Sometimes Al even had to accept handouts,gifts from his family and friends. But do not get me wrong. My friend was not a deadbeat. He was not the kind of person who never paid the money he owed. He simply _ pennies. He was always very careful with the money he spent. In fact,he was often a cheapskate. He did not like to spend money. The worst times were when he was flat broke and had no money at all. One day,Al scraped together a few dollars for a lottery ticket. He thought he would never strike it rich or gain lots of money unexpectedly. But his combination of numbers was chosen and he won the lottery. He hit the jackpot. He won a great deal of money. Al was so excited. The first thing he did was buy a costly new ear. He splurged on the one thing that he normally would not buy. Then he started spending money on unnecessary things. He started to waste it. It was like he had money to burn. He had more money than he needed and it was burning a hole in his pocket so he spent it quickly. When we got together for a meal at a restaurant,Al paid every time. He would always foot the bill,and pick up the tab. He told me the money made him feel like a million dollars. He was very happy. But,Al spent too much money. Soon my friend was down and out again. He had no money left. He was back to being strapped for cash. He had spent his bottom dollar, his very last amount. He did not even build up a nest egg. He had not saved any of the money. I admit I do feel sorry for my friend. He had enough money to live like a king. Instead,he is back to living on a shoestring--a very low budget. Some might say he is penny wise and pound foolish. He is wise about small things,but not about important things. Question: What can we learn from the story of Al? Yes or no, is the answer "Do not pick up the sesame seeds but overlook the watermelons."?
No

Article: A recently study found people's lives are made shorter in North China. It is showed the life expectancy had been cut down by 5.5 years there. Researchers think that the heavy air pollution in China should be to blame . It's really the truth. Our government has already done something. However, it doesn't seem to work so well. "Air pollution in China is doing harm to people's health. The harm is much more serious than we can imagine," said Chen Yuyu of Beijing University, one of researchers of this study. Dirty air brings serious problems in North China. In January this year, the air pollution was worse than that in other places. That was caused by rising temperature and waste gas from coal heating. Chinese government should strongly fight against air pollution. They should think of more proper ways to deal with the problem. People should be encouraged to take buses, ride bicycles or walk, instead of driving cars. The factories that pollute heavily should be closed. "We need to improve our environment, although it might be expensive. Protecting our environment means protecting ourselves," Li Hongbin, another researcher of the study said. Question: Which of the following is Li Hongbin's idea? Yes or no, is the answer "People need to make pollution less, although it might cost a lot."?
No
