When I was a teenager, my dad wasn't terribly interested in the music I liked. To him, it just sounded like "1 ", while he referred to the music he listened to as"2 ." As I've grown older, I'll often hear people of my age say things like "they just don't make3 music like they used to."

Luckily, my4 as a psychologist has given me some insights into this puzzle. We know that musical tastes begin to5 when we're teenagers. By the time we're in our early 20s, these tastes get locked into place pretty firmly.

In fact, studies have found that by the time we turn 33, most of us have6 listening to new music. Meanwhile, those familiar songs released when you're in your early teens are likely to remain quite7 among your age group for the rest of your life. There could be a biological8 for this. There's evidence that the brain's ability to make subtle distinctions between different chords, rhythms and melodies gets9 with age. So to older people, less10 songs might all "sound the same".

But I believe there are some simpler11 for older people's dislike of newer music-the "mere exposure effect". It means that the more we're12 to something, the more we tend to like it.

Psychology research has shown that the emotions that we 13 as teens seem more intense than those that come later. We also know that intense emotions are 14 with stronger memories and preferences. All of this might explain why the songs we listen to during this period become so memorable and beloved.

So there's15 wrong with your parents because they don't like your music. In a way, it's all part of the natural order of things.

When faced with tough difficulties or troubles, people always give us positive words. 1 can lift our spirits indeed, but sometimes in some case it 2 depresses us. Psychology calls it "toxic positivity." What is it? Let's see the following 3.

Between sleepless nights, diapers (换尿布) and feeding times, having small children at home could leave Priscilla Goins feeling 4. She loved her kids, but it was a lot. "I would sometimes say 'I just want a minute to myself,'" Goins, of Knoxville, Tennessee, said. "People would be like: Oh, you'll miss it when they're 5 or you should value it." That made her so mad. She doesn't 6 what people say. She disagreed at all. Actually, in those moments, she simply wanted 7 that she was going through the tiredness 8.

A focus on positive thinking, while putting challenging and 9 experiences to the side, is what some experts call "toxic positivity." Being cheerful is not a bad thing. Certainly, a 10 attitude can be a gift to those around you, but it shouldn't 11 listening thoughtfully to others' experiences. When you are choosing to look at 12 from one angle-in this case a positive angle-you are very likely to dismiss or deny an authentic 13. That's toxic positivity, which is what Goins 14 when she was looking for a bit of mercy about the 15 of parenting young children. Even if you're trying to 16 someone, ignoring someone's tough experiences can leave them feeling that they should 17 negative feelings in the future. 18 trying to find a positive spin, we are supposed to use accepting and comprehensive words. Sometimes we just need to say "Yeah, me too," or "That makes total sense." It's allowing someone to express something that is 19, even if it's hard to hear or it's 20.

    Our life has been taken over by modern technology, for good of course. Young people 1 the fast speed that technology can move at. But there is a group of people who cannot 2.

    It is the group of people who are caught up between traditional and  3 society, sort of like the middle child in technological advancement—not exactly old and 4 change, but trying very hard to become modernized, ending up being 5 in the middle .They are 40 to 60 years old and 6 the latest iPhone or Samsung phone or Huawei. They buy an iPad just 7 they can afford to, and play the same games on a larger screen.

    They are almost like the teenagers five years ago,8 on their phones playing a game or using social media. They're everywhere. And I saw something today that made me extremely 9.

    On a train, a mother was 10 playing a Candy Crush-like game. Her daughter was sitting beside her. The little girl, about five years old, was talking to her mother about her day,11 the next stop's name cheerily—with obviously desperate attempts to get her mother's 12.

    The mother? All she did was nod and say the occasional “mmhm”.With her eyes on the 13,she concentrated on completing the level. I watched the girl make a final 14 to get her mom to look at her, and when she failed, she 15 and fell silent and defeated.

    It broke my heart, and got me 16:What kind of game can make you17 that you have the most beautiful thing in the world, a person you love with all your heart? What does it 18 when you won't even look into her eyes or listen to her?

    The scene was so familiar years ago when parents 19 that their children were too interested in their mobile devices(设备).Look at how the tables have turned now. I'm 20 whether to laugh or to cry. But all I can do now is hope that this storm passes.
