A new study by US researchers has proven for the first time the causal connection between social media use and decreased mental health. Few prior studies have attempted to show that social media use harms users’ well-being, and even those that did explore the issue were limited in scope or based on unrealistic situations. Researchers at the University of Pennsylvania designed the study that focused on Facebook, Snapchat and Instagram, the three most popular social media platforms in the US. A total of 143 undergraduates at the university participated. They were randomly assigned into two groups: The control group was allowed to maintain their typical social media behavior; the experimental group was asked to limit their time on the three social media platforms to 10 minutes per platform per day. The participants completed a survey on their mood and well-being at the start of the study. After three weeks, they were tested again for outcomes such as fear of missing out, anxiety, depression and loneliness. Throughout the study, researchers also collected objective usage data automatically tracked by iPhones for active apps, not those running the background. As a result, researchers found that the group of limited social media use showed significant reductions in loneliness and depression over three weeks compared to the control group. “Using less social media than you normally do would leads to significant decreases in both depression and loneliness. These effects are particularly pronounced for folks who were more depressed when they came into the study,” Hunt said in a press release. It’s a little ironic that reducing the use of social media actually makes people feel less lonely, but the findings make sense when digging a little deeper, she said. “When you look at other people’s lives, particularly on Instagram, it’s easy to conclude that everyone else’s life is cooler or better than yours,” she explained. Hunt admitted that the study only looked at three major social media platforms and that the results may vary if applied to different age groups. The study was published in the latest issue of the Journal of Social and Clinical Psychology. 18. What did the researchers find out in the study?
A、The less time one spends on social media, the less depressed and lonely he feels.
B、One will feel more energetic after using social media.
C、Social media enables users to live a full life.
D、If one spends less time on social media, he will get more loneliness and depression.
Click to the Sixth Century BC. Hippasus of Metapontum stands on a boat in the Aegean, pondering his fate. Pythagoras himself sentences him to death for revealing a secret that undermined the Greek way of thinking.
Pythagoras is noted throughout the world for his famed theorem; the square of the hypotenuse of a right triangle is equal to the sum of the squares of the other two sides. The theorem makes the universe understandable. (1) Its ratios and proportions are keys to explaining mathematics, science, music, nature, harmony and beauty in a civilized society.
The problem is that Pythagoras had it wrong. To the Greeks the number zero does not exist. A ratio with zero in it defies nature, and thus the logic of the universe. But the math is incontrovertible. The Pythagoreans figure it out, responding by forming a brotherhood to deny the existence of zero, to preserve the mathematical laws that make them leaders in civilized society, and to protect their charismatic leader.
Hippos, a mathematician and member of the brotherhood, spills the secret about irrational numbers and an irrational universe. The Pythagoreans take him to sea, tossing him overboard for exposing a self-serving theory with an unpopular truth.
Click to present day. Washington Post executive editor Leonard Downie Jr. and former Post associate editor Robert Kaiser arrive to deliver "the news about the news. " (2) The Washington Post editors make an old argument for a new time; news is sinking to another new low. Downie and Kaiser blame consolidation, convergence, and proliferation of media for undermining good journalism and failing to inform. society. They acknowledge that they come to their perspective from "the privileged perch" of The Washington Post The view from the privileged perch is predictably Pythagorean.
As an interconnected society moves toward participating in the news, the Brotherhood of new seeks to protect its values and exert its control. (3) Just as zero changed the equation shaping humanity's vision of the universe, accessible media changes the equation that shapes news and informs society. Everyone is a journalist in the age of access. But for most news organizations, collaboration with their audience is an irrational concept, a dangerous idea.
Click back to Pythagoras. The story unfolds like a video game. A health-conscious leader who believes indigestion causes all disease, Pythagoras especially fears beans because they cause flatulence in past, present and future lives. (4) His arrogance grows, his views become extreme, and soon his secret society crumbles. Enemies set out to kill him. A mob sets his house on fire.
Members of the brotherhood are slaughtered. Pythagoras flees, but he spots at a bean field, declaring that he'd rather be killed than cross the field. His pursuers oblige. They cut his throat (5) Arrogance and eternal flatulence. Pythagoras dies for behaviors and beliefs that put him out of touch with the rest of the world.
