Tips for understanding body language include watching the eyes, learning what information posture demonstrates and examining the lower body during conversations. When looking for signals from a person's body language, it is typically more accurate to evaluate body language as a whole instead of looking at singular actions.
Blinking more frequently than usual is a sign of stress or discomfort, while blinking less frequently than usual may indicate the person is attempting to hide signals from the eyes. If a person looks directly at another person and makes eye contact frequently, it indicates interest, while looking away often indicates nervousness or distraction.
The two types of posture are open and closed posture. Open posture, which involves keeping the torso open to another person, indicates friendliness. Closed posture, which involves covering the torso, often indicates hostility or discomfort.
The legs and feet are often indicators of a person's true body language, especially when that person is trying to conceal it. While people can disguise body language, they often forget about their lower bodies or don't rehearse normal lower body activities. When stressed, for example, it is common for the feet and legs to move rapidly or fidget.
When people use similar body language, it typically means they agree with one another. A listener can demonstrate that he agrees with a speaker by using the same body language.
