为什么你常常“话到嘴边”就忘了？

　　导读:你是不是也有这样的时刻，想说的话刚到嘴边就记不起了。发生了什么，我是谁，我在哪里。。。这篇文章给了你解释。

There you are in the middle of a conversation, and suddenly you draw a blank on a particular word. It’s right there … if you could just remember …

　　You move on, and hours later, something jogs your memory and the word comes to you, long after its relevance has passed.

　　So, what happened?

　　You experienced what researchers call a tip-of-the-tongue state, that agonizing moment when you know precisely what you want to say but you fail to produce the word or phrase.

　　Far from being telltale signs of dementia or Alzheimer’s disease, these moments are simply part of the way we communicate, and they’re more or less universal.

　　“You can’t talk to anybody, in any culture, in any language, in any age group, that doesn’t know what you’re talking about” when you describe a tip-of-the-tongue state, said Lise Abrams, a psychology professor at the University of Florida who has studied the phenomenon for 20 years. Researchers have even found occurrences among sign language users. (Those, they call tip-of-the-finger states.)

　　We’re more likely to draw blanks on words we use less frequently — like abacus or palindrome — but there are also categories of words that lead to tip-of-the-tongue states more often.

　　Proper names are one of those categories. There’s no definitive theory, but one reason might be that proper names are arbitrary links to the people they represent, so people with the same name don’t possess the same semantic information the way that common nouns do, Abrams said.

　　Here’s an experiment: Think of the first and last name of the foul-mouthed chef who has a cooking show on Fox. Now think of the hand-held device with numbered buttons you use to add, subtract, multiply or divide.

　　Which was easier to recall?

　　In all likelihood it was “calculator,” since every calculator you’ve ever seen shares those exact same attributes, giving you more context you can draw from when trying to produce the word. (That chef, by the way, is Gordon Ramsay.)

　　The bad news is there’s not a whole lot we can do in the moment to jog our memory when this happens. However, using certain words or names more often can make you less likely to draw a blank when you’re trying to produce that word, name or phrase.

　　So if you can never seem to remember the name of that guy in administration when you’re talking about him, try saying his name out loud when you can: It just might save you a little embarrassment down the road.
