It's well-known by all the people to greet friends with a smile and a wave.{#blank#}1{#/blank#} However, what happens if your face and body send mixed messages? Would someone tend to believe the look on your face or the way you behave?

    Recently, scientists have dealt with these questions. They found that when a person is staring at your face, he might not believe what he sees if your body doesn't match the feeling that your face shows.{#blank#}2{#/blank#}Previous study had showed that the tone of a person's voice can be more important than the words spoken. For example, most people are more likely not to believe a person who says in a flat voice, "I'm so excited."

To test if this was true, psychologists from the Netherlands and Boston showed people a number of pictures of isolated faces and isolated bodies that showed anger or fear,{#blank#}3{#/blank#}

    An angry face had low eyebrows and tight lips. A frightened face had high eyebrow and a slightly open mouth{#blank#}4{#/blank#} A scared body had arms forward and shoulders square, as if ready to fight back.

    These results told the researchers that mixed messages can confuse people. Even when people pay attention to the face, body language surely influences the emotion they read.
