Article: Spending a lot of time watching TV, playing video games and surfing the Web causes a lot of healthy problems to children such as overweight and smoking, US researchers said yesterday. U.S. experts analyzed 173 studies on how media sources influence the physical health of children and adolescents . The studies, mostly carried out in the prefix = st1 /United States, largely focused on television, but some looked at video games, films, music, computer and Internet use. Three quarters of them found that increased media viewing was connected with poor health. The studies offered strong evidence that children who get more media exposure are more likely to become overweight, start smoking and begin earlier sexual activity than those who spend less time in front of a screen, the researchers said. Studies also showed more media exposure is linked to drug and alcohol use and poorer school performance. "We were pretty surprised by the number of studies that showed these negative health results," said one of the researchers in the report. For decades, experts have worried about the effect on young viewers of the violence and sexual content in some TV programs, movies and video games. Another issue is that kids are spending time sitting on a couch watching TV or playing computer games when they could be running around outside. One study found that children who spend more than eight hours watching TV per week at age 3 are more likely to be overweight at 7. And research showed that many USchildren watch far more. Another study showed TV and other media content can have a deep influence on children's attitudes and beliefs, particularly among teens. A US study published in November showed that adolescents who watched more programs with sexual themes had a higher risk of becoming pregnant or causing a pregnancy. Thirteen of 14 studies that evaluated sexual behavior found a connection between media exposure and earlier sexual behavior, the researchers said. Question: According to the passage, too much media exposure may cause the following EXCEPT _ . Yes or no, is the answer "progress in school subjects"?
No

Article: Our senses aren't just delivering a strict view of what's going on in the world; they're affected by what's going on in our heads. A new study finds that hungry people see food-related words more clearly than people who've just eaten. Psychologists have known for decades that what's going on inside our head affects our senses. For example, poorer children think coins are larger than they are, and hungry people think pictures of food are brighter. Remi Radel of University of Nice Sophia-Antipolis, France, wanted to investigate how this happens. Does it happen right away as the brain receives signals from the eyes or a little later as the brain's high-1evel thinking processes get involved. Radel recruited 42 students with a normal body mass index. On the day of his or her test, each student was told to arrive at the lab at noon after three or four hours of not eating. Then they were told there was a delay. Some were told to come back in 10 minutes; others were given an hour to get lunch first. So half the students were hungry when they did the experiment and the other half had just eaten. For the experiment, the participant looked at a computer screen. One by one, 80 words flashed on the screen for about l/300th of a second each. They flashed at so small a size that the students could only consciously perceive. A quarter of the words were food-related. After each word, each person was asked how bright the word was and asked to choose which of two words they'd seen-a food-related word like cake or a neutral word like boat. Each word appeared too briefly for the participant to really read it. Hungry people saw the food-related words as brighter and were better at identifying food- related words. Because the word appeared too quickly for them to be reliably seen, this means that the difference is in perception, not in thinking processes, Radel says. "This is something great to me. Humans can really perceive what they need or what they strive for. From the experiment, I know that our brain can really be at the... Question: What can we infer from the passage? Yes or no, is the answer "Humans can perceive what they need without involving high-level thinking processes"?
Yes
