部分音乐享受能力或来自遗传

2025-04-03 17:47 by 十二魔

马普心理语言学研究所的研究人员对 9169 名瑞典双胞胎样本进行了分析,发现个体在音乐享受上的差异有相当一部分是由遗传因素引起的。研究人员使用“音乐奖励敏感性”(Music Reward Sensitivity)来描述个体对音乐所带来的愉悦感和奖励体验的敏感程度。9169 名年龄在 37 岁至 64 岁之间的瑞典双胞胎参与了问卷调查。双胞胎研究是研究遗传和环境因素对特定形状或行为影响的强大工具,这种方法不需要直接进行基因测序,而是通过比较同卵双胞胎(基因几乎完全相同)和异卵双胞胎(基因相似性约为 50%)之间的相似性来推断遗传因素的作用。研究发现,双胞胎在音乐奖励敏感性上的差异中有 54% 可以用基因差别来解释,这表明享受音乐的能力有一大部分来自遗传。除此之外,音乐奖励敏感性的遗传影响部分独立于一般奖励敏感性和音乐感知能力,这表明享受音乐与“听懂”音乐等认知过程可能使用了不同的神经机制。

Can I mute a Telegram group?

In recent times, Telegram has gained a lot of popularity because of the controversy over WhatsApp’s new privacy policy. In January 2021, Telegram was the most downloaded app worldwide and crossed 500 million monthly active users. And with so many active users on the app, people might get messages in bulk from a group or a channel that can be a little irritating. So to get rid of the same, you can mute groups, chats, and channels on Telegram just like WhatsApp. You can mute notifications for one hour, eight hours, or two days, or you can disable notifications forever.

Tata Power whose core business is to generate, transmit and distribute electricity has made no money to investors in the last one decade. That is a big blunder considering it is one of the largest power generation companies in the country. One of the reasons is the company's huge debt levels which stood at ₹43,559 crore at the end of March 2021 compared to the company’s market capitalisation of ₹44,447 crore.
