（单词翻译）

 Many of us talk with our hands. But some researchers suspect we may listen with our hands, too.

 
Cognitive1 scientists had subjects listen to spoken sentences, each in the third person and present tense, such as “John walks to work.” As they listened, the subjects pinched a grip-force sensor2.
 
The researchers found that subjects increased their grip when listening to action words that involved hands or arms, such as scratch, throw or lift. But this response depended on context—grip force was unchanged when the action was negative, as in "Laura did not lift her luggage." The study is in the journal PLoS One. 
 
The results demonstrate how words subtly and selectively induce motor activity. The fact that this motor response depends on context is a testament3 to our brain's flexibility4 when processing words.
 
The study also adds to the growing evidence that sensory-motor and language experiences are linked in the brain. Figuring out this connection could lead to new therapies for speech and language disorders5. In the meantime, the next time you tense up over a game of mad libs, do go easy on those verbs.
