Most of the time, words are not enough to express how someone really feels. And sometimes, what we say are not really what we intend to convey. This is where nonverbal communication gains its importance in the interaction of two or more people.
Body language, a form of nonverbal communication, is the conscious and unconscious use of gestures and body movements to send messages, moods, feelings, and state of mind. You can easily identify one's emotions if you know how to read and interpret his or her actions.
This emotion is probably the easiest to identify from one person. Aside from the increasing of the voice volume, facial movements could identify anger or fury. It could be identified by one hard, intense look on the source of his anger or when the eyebrows would meet at the center slightly above the bridge of the nose. Other facial body language involved in this emotion include nasal flaring, teeth baring, snarling, flushing of the face, shallow breathing, and tightening of the lips and jaw.
A person with a clenched fist, perspiration, his hands on the waist, or arms crossed across the chest are signs of anger as well.
Nervousness, Tension, And Anxiety
The most common signs of these emotions are dry mouth, pale face, trembling of the lips and fingers, and perspiration. A nervous or anxious person would tend to move a lot to remove the tension off his body, thus he would fidget, rock or tap his feet, drum his fingers on a surface, or pace around the room back and forth. Lack of eye contact or the inability to hold prolonged eye contact is also an indication of these emotions.
