Nonverbal communication

Historically, human beings have different ways of communication which can be basically divided into verbal and nonverbal. Unlike verbal communication, nonverbal communication does not involve voice but rather implies the use of gestures, mimics, i.e. the body language. At first glance, nonverbal communication seems to be not very effective, especially compared to verbal one, but, in actuality, the effectiveness of nonverbal communication is quite high as individuals perceive the body language instinctively and, to a certain, on the subconscious level. This is why it is possible to use nonverbal language to achieve different purposes of communication.
It is not a secret that nonverbal communication may be really helpful for running a meeting. In fact, while running a meeting it is extremely important to use body language effectively, the basic goal of the head of the meeting is to attract general attention and focus it on the subject of the meeting. For this purpose it is possible to use a variety of means such as holding the hand up in order to draw attention of other people, or else, it is possible to move during the meeting making all people focused on the head of the meeting. By the way the same recommendations may be used if it is necessary to call the meeting to order, though it is also possible to clap not very strongly but soundly enough in order to draw attention and reestablish order. It is also possible to emphasize important topics by raising a hand with a pointed figure, for instance. It is also possible to show approval by nodding the head or express reservations by avoiding looking at the eyes of other people present on the meeting. Naturally, it is possible to regulate the flow of conversation or invite a colleague to continue with a comment by means of gestures, inviting by the hand movement to continue the conversation or stop it.
Thus, nonverbal communication may be quite an effective tool of running a meeting.
