    (22) [Why do old people dislike new music?] As I’ve grown older, I often hear people my age say things like, “They just don’t make good music like they used to.” Why does this happen? Luckily, psychology can give us some insights into this puzzle. Musical tastes begin to crystallize as early as age 13 or 14. By the time we’re in our early 20s, these tastes get locked into place pretty firmly.

    (23) [In fact, studies have found that by the time we turn 33, most of us have stopped listening to new music.] Meanwhile, popular songs released when you’re in your early teens are likely to remain quite popular among your age group for the rest of your life. There could be a biological explanation for this. As there’s evidence that the brain’s ability to make subtle distinctions between different chords, rhythms, and melodies deteriorates with age, so to older people, newer, less familiar songs might all sound the same.

    (22) [But there’re maybe some simpler reasons for older people’s aversion to new music.] (24) [One of the most researched laws of social psychology is something called the “mere exposure effect”, which in essence means that the more we’re exposed to something, the more we tend to like it.] This happens with people we know, the advertisements we see, and the songs we listen to. When you’re in your early teens, you probably spend a fair amount of time listening to music or watching music videos. Your favorite songs and artists become familiar, comforting parts of your routine. For many people over 30, job and family obligations increase. So there’s less time to spend discovering new music. Instead, many will simply listen to old familiar favorites from that period of their lives when they had more free time.

    Of course, those teen years weren’t necessarily carefree. They’re famously confusing, which is why so many TV shows and movies revolve around high school turmoil. Psychology research has shown that (25) [the emotions that we experience as teens seem more intense than those that come later. And we also know that intense emotions are associated with stronger memories and preferences. Both of these might explain why the songs we listen to during this period become so memorable and beloved.] So there’s nothing wrong with your parents because they don’t like your music. Rather, it’s all part of the natural order of things.

24. What do we learn from one of the most researched laws of social psychology?（从社会心理学研究得最多的一个规律中，我们能了解到什么？）

解析：A。四个选项都使用了“The more...the more...”句型，且每个选项前半句话的意思相近，因此选出答案的关键在于关注每个选项后半句话的不同。录音中间部分提到，社会心理学研究最多的规律之一是所谓的“纯粹暴露效应”，从本质上讲，这意味着我们与某种东西接触得越多，我们就越喜欢它。A项与此内容相符，其中The more you experience something是对录音中the more we’re exposed to something的同义替换，the better you’ll appreciate it是对录音中the more we tend to like it的同义替换，故正确答案为A。

错项排除：B、C、D三项分别利用录音中出现的memorable、the more we’re exposed to something和familiar设置干扰，但关于社会心理学研究最多的规律，录音中没有提及记忆时长、理解深度和熟悉度等信息，故排除B、C、D三项。
