人们认为，随着时间的推移，人类的认知系统从根本上限制了注意力的分配。这种限制反映在注意力眨眼上，即识别连续出现的两个视觉目标中的第二个的能力受损。我们报告了一个矛盾的发现，即当观察者同时从事分散注意力的心理活动时，如自由联想与任务无关的主题或听音乐，注意力眨眼显著改善。这一发现提出了关于注意力眨眼的基本性质的问题，并表明注意力的时间动态是由任务环境决定的，这些任务环境会诱发或多或少分布的精神状态。
It is believed that the human cognitive system is fundamentally limited in deploying attention over time. This limitation is reflected in the attentional blink, the impaired ability to identify the second of two visual targets presented in close succession. We report the paradoxical finding that the attentional blink is significantly ameliorated when observers are concurrently engaged in distracting mental activity, such as free-associating on a task-irrelevant theme or listening to music. This finding raises questions about the fundamental nature of the attentional blink, and suggests that the temporal dynamics of attention are determined by task circumstances that induce either a more or a less distributed state of mind.
