Our brain releases a chemical called dopamine, which we also get from activities like exercising and listening to music. This creates feelings of pleasure that we want to repeat again and again. Many TikTok users show signs of addiction when watching the short and interesting clips. It can be very difficult for them to stop watching these short videos, even when they have something more important to do. This behavior trains the brain to expect instant satisfaction, thus making people’s attention spans shorter in the long run.
我們的大腦會釋放一種叫做多巴胺的化學物質，我們也可以從運動和聽音樂等活動中獲取。這會產生我們想要一次又一次重複體驗的愉悅感。許多 TikTok 用戶在觀看簡短且有趣的短片時會表現出上癮的跡象。即使他們有更重要的事情要做，他們也很難停止觀看這些短影音。這種行為會訓練大腦期待立即的滿足感，從長遠來看會使人們注意力持續的時間因此縮短。
生活必備字詞：
