Interaction  demonstrate   approve of       

 clue    gesture      

When we think about nonverbal behaviour, or body language, we think about communication. When we think about communication, we think about           . So what is our body language                          

to others? Social scientists have spent a lot of time looking at the effects of our body language. We make assessments and inferences from body language. And according to those judgements we               one person and dislike another. So body language provides         external that are influenced by

internal thoughts and feelings. Scientists have found that when we feel proud and powerful, we usually straighten up to make ourselves bigger.

           , when we feel powerless, we tend to slump, making ourselves smaller. It is obvious that our minds can influence our bodies. But is it also true that our bodies can affect our minds? Scientific experiments show that if we make powerful         long enough, we may actually feel more powerful. People who remember to use positive body language are more likely to feel positive         , so some scientists suggest that we use our bodies to try power posing to

help          our feelings of shyness and powerlessness.
