Speech：The “ micro expression” I’m very interested in psychology, and I found that the analysis of “micro expression” is very hot these years , so , what I’m going to talk about today is “ micro expression”. Before I get started, I want to show you a picture. This picture is from<神雕侠侣>, let’s pay attention to women’s face. How many feelings can you read from her face? If we cover her eyes, only see the bottom half of the expression, we’ll find she was happy. But when we cover her mouth, and see the top half , we’ll find she was sad. This is the classical micro expression what we called “mixed feelings”. And this facial expression is when the man said he loves her. The woman was very happy knowing that the man is willing to die for her, but also felt very sad, because both of them will stuck and die in the ancient tomb. It’s very hard for us to do this expression, if you don’t believe me, you can faced to your partner and have a try. Maybe all of us are not new to “micro expression”, and many people are accustomed to think that “micro expression” refers to the subtle changes of our faces. But actually, it’s not only limited to the subtle changes of faces, but also includes someone’s standing posture, sitting posture or other outward expressions. For example, when we feel dangerous or unfavourable in some conditions, you’ll find the muscles in your body are contracting, some people may clench our fists, look around warily. Others may trembling with nervousness, just like me on the stage. All those behaviors are micro expressions. In other words, the “micro expression” almost include every language performance and physical behaviors. We’re not all going to become facial expression experts overnight , but there’s one I can show you that’s very dangerous and it’s very easy to learn, and that’s the expression of contempt. Now with anger, you’ve got two people on an even playing field. It’s still somewhat of a healthy relationship. But when anger turns to contempt, you’ve been dismissed. It’s associated with moral superiority. And for that reason, it’s very, very hard to recover from. Now, the technology around what the truth looks like is progressing on, the science of it. But when we are having class or meeting ,maybe none of us like with a lie detector on our side. So maybe the technology of “micro expression” may will prove incredibly useful some day. If there are some wrong words or expressions, please tell me, thank you ~
