Nonverbal communication in psychology means that our communication through the tone of voice, our gestures and posture are analyzed and have different meanings. There is a great deal of misinformation and misunderstanding in face-to-face human relations. Here we often cannot see what is going wrong. To understand fully the role of nonverbal communication in social psychology, it is important to analyze the perception side and the expression side. When a dog bares its teeth or wags its tail, it communicates its likely following actions, communication which both humans and other species understand. Such communications are adaptive and allow members of a species to live in close proximity and to interact efficiently.

Experts  also believe that primates, including humans, use nonverbal communication (facial expressions, gestures, sounds) to indicate emotional states. Movement such as crossing the arms, lowering the head, and standing rigidly, for example, can communicate in body language a negative attitude. Stress can be seen when a person can`t stand still. Happiness is when somebody is smiling a lot, or when sings a melody on a lower voice just for himself.

All of our moves, gestures or posture means something. It`s important to never show what`s on your mind. A person that can control these things has a lot to gain. If you know and notice what a person means through it`s gestures that you can read that person like an open book. Smiling and talking often hides what you are really feeling, but there are some things that give you away.
