 When you use your top-down attention to focus on something, your brain activates 1 inhibitory mechanisms 2 to block out competing stimuli 3. It can't do this forever, though; these mechanisms eventually tire just like the muscles in our body, and this leads to something called Directed Attention Fatigue 4.

当你运用由上至下的注意力,专注在某件事上时,你的大脑会启动抑制机制来阻挡其它会分散注意力的刺激物。不过,大脑也没办法永远持续这个状态。这种抑制机制就像我们身上的肌肉一样,终究还是会疲乏,而导致所谓的导向性注意力疲乏。
