We can easily identify what emotions someone is experiencing by simply, looking at their gestures, movements, posture, or listening to their tone of voice. Body language also shows their attitude as well.

Body language is very useful in our everyday life. For example, someone is telling you something about your school work, you may not remember all of what they said, you then remember some gestures they used to emphasize a point. Everything comes back to you. This makes clear the point that you remember what you see rather than what you hear.

Using positive body language shows that you are interested in the conversation or person you are talking to. Using a flat tone of voice and very little movement shows a lack of interest. You tend to be more lively when you are interested in something.

However, not everybody who suddenly crosses their arms is "angry" or "closing themselves out", or someone who yawns during a meeting isn't necessarily "bored". So just be careful, when trying to interpret someone's body language.

The disgust that shows on the face of a child who is given something to eat that they do not like is easy to read. Along with body language, facial expressions of emotions help us to react to others in suitable ways. If someone is looking very sad, it may not be the best time to crack a joke about their shoes. On the other hand, it may be just what they need.

While we can show emotions through our facial expressions, we can also hide our feelings. The expression "poker face" is used to describe people who can keep the same expression throughout a game of poker regardless of how good or bad the hand may be. It seems that some of this control is unconscious and develops by watching others. Some people are also very good at "putting on a happy face". This is a talent that actors need as they use facial expressions to portray emotions in a show.
