作者报告了对人们忧虑时工作记忆容量的首次直接评估。高忧虑者和低忧虑者在思考当前担忧或积极的个人相关主题时执行随机按键任务。高度忧虑者（但不是低度忧虑者）在忧虑期间表现出比在思考积极话题时更多的能力受限证据。这些发现表明，高度忧虑的人在忧虑时的剩余工作记忆容量比思考其他话题时要少，因此，可用于将他们的想法从忧虑中转移出来的注意力资源也较少。
The authors report the first direct assessment of working memory capacity when people engage in worry. High and low worriers performed a random key-press task while thinking about a current worry or a positive personally relevant topic. High (but not low) worriers showed more evidence of restricted capacity during worry than when thinking about a positive topic. These findings suggest that high worriers have less residual working memory capacity when worrying than when thinking about other topics and, thus, have fewer attentional resources available to redirect their thoughts away from worry.
