This article explains how microexpessions are accurate, yet hard to read consistently. These microexpressions display varying emotions that can help humans stay out of danger, comfort a friend, etc.

Very cool results. At first, I wasn't sure if there was actually a way to gather this data, but it appears that with lots of training, it can be quiet easy to find things out!

If you're interested in learning more about it, consult Paul Eckman's research into microexpressions and the Facial Action Coding System (FACS). The animation industry depends on FACS, in fact!

Take a look at Dr. Paul Eckman's research on Facial Action Coding System, also bookmarked here (FACS)

The face is the easiest way to tell someones emotions. A Scientist studied blind people and noticed that even they make facial expressions when they feel a certainn way. There are 7 different micro expressions: surprise, fear, disgust, anger, happiness, sadness, and hate.

Launches a flash application in which you can watch muscles of the face engage to reveal certain emotions...useful in detection of lying or "fake smiles."

An interesting story--my students, you might recall Sheryl Turkle of MIT referencing robot therapists in her TED talk. USC has developed a robot therapist, Ellie, designed to talk to people who are struggling emotionally, and to take their measure in a way no human can. Originally developed to work with military PTSD patients, Ellie's purpose: to gather information and provide real human therapists detailed analysis of patients' movements and vocal features, in order to give new insights into people struggling with emotional issues. The body, face and voice express things that words sometimes obscure. Ellie's makers believe that her ability to do this will ultimately revolutionize American mental health care.

"Thoughtful questions often prompt thoughtful analysis and recently a series of questions from a reader regarding 'micro-expressions' had such an effect on me. His questions made me stop and think about how the public perceives 'micro expressions' and their significance in our overall understanding of body language, and more importantly, their relevance in detecting deception."

Difficulty of capturing micro-expressions

I wonder what the effects of possessing the skill to read others' facial expressions would produce. Would it strengthen our relationships with people or weaken them?

When the article said that misreading emotions is worst than not knowing of the emotion at all is worst, I question whether reading emotions is even worth it. Also, compared to a century ago, the divorce rate has skyrocketed. Could the lack of reading emotions be the cause of this increase? Emotions are innate and humans have always read or not read emotions. What's the difference between now and then? Freedom? So what if you can read someone's emotions? If you can't assist the person in his/her tragedy or emotional stress being able to read emotions is worthless. In addition Paul Ekman said that the percent rate after his lessons on DVD rose to 80-85%, but that still leaves 15%-20% of mistake. As i previously said, the article says that misreading emotions is worst than not knowing of the emotions at all. There's still of chance of being worst. Are we really accomplishing whatever we are trying to do by learning how to read emotions?

This is a very cool article, as it has caused me to become more aware of other people's reactions - sometimes I know that someone is holding an emotion in, but hopefully, through observing their facial gestures, perhaps I can find out how they feel.
