people of all ages and genders used space-filling words like "um" and "uh" at about the same rates.
不同年龄、不同性别的人使用“um”、“uh”等填充词的频率大致相同。

researchers took a recording of a radio talk show caller and manipulated it in a couple ways,

Over 1000 participants were a part of this study.
1000多人参与了此项研究。
Each person listened to one of these three recordings.
每个人都听了这三段录音中的一段。
And when everyone was asked afterward to rate how frequently the speaker used filler words,
之后，每个人被要求评估说话者使用填充词的频率时，
they all gave about the same rating.
他们给出的评级差不多。
Unless they were told to pay attention to the speaker's style, then they noticed the filler words a lot.
除非他们被告知注意说话者的风格，才会更多地注意填充词。
But if they were told to specifically pay attention to the arguments,
但是如果听众们被告知要特别注意论点的话，
listeners seemed to ignore the filler words entirely.

One 2004 study found evidence of this by analyzing conversations at a speed dating event.

Women reported liking men more when they used short, filler-word interjections like "uh-huh" and "okay"while listening.
男性在女性倾听过程中使用短暂的填充词比如“uh-huh”，据报道女性会更喜欢他们。
Although these signals didn't seem to matter much the other way around.

And a 2011 study found that telemarketers who used these kinds of interjections while listening
2011年的一项研究发现，电话推销员在倾听中使用这些插入语时，
were given higher ratings of competence by a panel of participants.
会被一组参与者给予更高的能力评分。
So if you're using filler words way more than most people,
所以如果你比大多数人更多地使用填充词，
it might not be a bad idea to practice cutting back a bit.
练习着减少一点儿似乎不是坏主意。
But there's no reason to get rid of them entirely.
但没有理由完全抛弃它们。
They're probably helping your conversations along.
