自言自语益处多多?

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。

The second experiment saw participants performing a virtual shopping task, where they were shown photographs of items commonly found on supermarket shelves. 第二组实验中，被测者要完成的是虚拟购物任务，他们看到的是超市里常见的商品照片。

They were asked to find all instances of a particular item, so if they were asked for apples they had to find all the bags of apples, as quickly as possible. 研究人员要求他们找出某件商品的所有货物，比如说苹果，他们就要尽快找出所有的苹果。

The University of Wisconsin-Madison and University of Pennsylvania, both US, researchers found there was an advantage in saying the name of the product aloud when they were searching for something familiar. 威斯康星大学麦迪逊分校与宾夕法尼亚大学的研究人员都发现大声讲出要找的产品会事半功倍。
