Space. Have you ever been uncomfortable during a conversation because the other person was too close and entered your room? We all need a physical space, although this need varies depending on the culture, situation and proximity of the relationship. You can use physical space to communicate many non-verbal messages, including signals of intimacy and affection, aggression or domination. However, this does not mean that you have no control over your non-verbal cues. For example, if you don`t agree or don`t like what someone says, you can use negative body language to refute the person`s message, for example. B to cross your arms, avoid eye contact or tap on your feet. You don`t need to agree, or even like what is being said, but to communicate effectively and not put the other person on the defensive, you can consciously try to avoid negative signals – by keeping an open attitude and really trying to understand what they are saying and why. Research on non-verbal communication was initiated in the mid-1960s by a number of psychologists and researchers. Michael Argyle and Janet Dean Fodor, for example, studied the relationship between eye contact and conversation distance. Ralph V. Exline studied the patterns to see by talking and listening.  Eckhard Hess has produced several pupillaltation studies published in Scientific American.
Robert Sommer has studied the relationship between personal space and the environment.  Robert Rosenthal found that the expectations of teachers and researchers could influence their outcomes and that subtle and non-verbal indications could play an important role in this process.  Albert Mehrabian studied nonverbal references to sympathy and immediacy. In the 1970s, a number of scientific volumes in psychology summarized the growing volume of research, such as Shirley Weitz`s Nonverbal Communication and Marianne LaFrance`s And Clara Mayo`s Moving Bodies.  Popular books were Body Language (Fast, 1970), which focused on how to use non-verbal communication to attract others, and how to read a person Like a Book (Nierenberg- Calero, 1971), which studied nonverbal behaviour in negotiation situations.  The journal Environmental Psychology and Nonverbal Behavior was founded in 1976.  The most important information exchanged in conflicts and conflicts is often communicated in a non-verbal manner. Non-verbal communication is transmitted through emotional expressions, posture, gestures, tempo, sound and voice intensity. In communication, non-verbal messages can interact with verbal messages in six ways: repeat, contradict, complete, replace, regulate and moderate.
