Prof Gary Lupan and Prof Daniel Swingley, writing for the Quarterly Journal of Experimental Psychology, believe the next time you lose your keys, muttering 'keys, keys, keys' while looking could in fact help people find them. 加里卢潘与丹尼尔斯文雷两位教授，在《实验心理学季刊》上发表了他们的见解：下一次你再找不到钥匙，边找边小声念“钥匙，钥匙”会帮到你。

Inspired by viewing people audibly muttering to themselves as they try to find things like peanut butter in a supermarket, researchers conducted two experiments to see if this actually worked. 研究人员看到人们在超市里一边找花生酱一边念叨，由此想到了这个办法，并做了两个实验来证明“念叨”是有效的。

In the first, participants were shown 20 pictures of various objects and were asked to find a certain one, with some seeing a text label telling them what they were looking for. 第一组实验中， 研究人员给被测者看20个物品的照片，要求他们找到其中一个指定的物品，其中一部分人看到的是丢失物体的文字标签。

These participants were then asked to search for the item again while saying the word to themselves, with results showing saying it aloud helped people find the object more quickly. 随后，研究人员要求被测者一边找去一边念叨要找的物品。结果发现自言自语的被测者能更快地找到东西。
