請依下文回答第 31 題至第 35 題Nowadays, in public or private places, we tend to scroll mindlessly through our social media feeds when wehave a few spare minutes (or for some, hours). And as we probably know intuitively, and as the research isconfirming, it is not the best habit when it comes to our collective psychology.The American Academy of Pediatrics has warned about the potential for negative effects of social media in youngkids and teens, including cyber-bullying and “Facebook depression.” But the same risks may be true for adults, acrossgenerations. A review study suggests “Facebook Addiction Disorder” because addiction criteria, such as neglect ofpersonal life, mental preoccupation, escapism, mood modifying experiences, tolerance and concealing the addictivebehavior, appear to be present in some people who use social networks excessively. A study also shows when people stopusing the Internet, they also undergo small but measurable physiological effects.Rather than enhancing well-being, as frequent interactions with supportive offline social networks powerfullydo, the current findings demonstrate that interacting with Facebook may predict the opposite result for youngadults—it may undermine it. In fact, another study found that social media use is linked to greater feelings ofsocial isolation, mentally and physically.Facebook is also a jealousy generator. We fall into the trap of comparing ourselves to others as we scrollthrough our feeds, and make judgments about how we measure up. One study looked at how we make comparisonsto others posts, in “upward” or “downward” directions—that is, feeling that we are either worse or better off thanour friends. It turned out that both types of comparisons made people feel worse, which is surprising, since in reallife, only upward comparisons (feeling another person has it better than you) makes people feel bad. But in thesocial network world, it seems that any kind of comparison is linked to depressive symptoms.All of this is not to say that there is no benefit to social media—obviously it keeps us connected across greatdistances, and helps us find people we had lost touch with years ago. But getting on social networks when youhave some time to kill, or, worse, need an emotional lift, is very likely a bad idea. If you are feeling brave, trytaking a little break, and see how it goes. And if you are going to keep “using,” then at least try to use in moderation.
