Non verbal communication includes the following aspects:
Patterns of touch
Of all the non verbal factors mentioned here, one should be aware of body language, as beyond the words this speaks volumes. Thus, one needs to learn how to effectively use their body to communicate better.
Take for instance, eye contact. Eye contact is an important channel of interpersonal communication. This factor helps regulate the flow of communication. It signals interest in others. Furthermore, eye contact with the audience increases the speaker's credibility. It is also an important part of effective team communication skills.
Another instance are the varied facial expressions. Take for example, the importance of the smile... it is regarded as a powerful cue that transmits: happiness, friendliness, motivational, warmth, liking, affection, etc. With a gentle smile on the face one is sending out a friendly signal, which is almost always reciprocated in a positive manner.
Gestures are another important part of non verbal communications. If one fails to use gestures while speaking, they tend to be perceived as boring, stiff and unanimated. A lively and animated teaching and speaking style captures the audience attention, at any given point. For example, nodding the head, communicates positive reinforcement, indicating that the speaker is being heard.
Other aspects of the body that are important in communicating is the posture of the body; as well as the proximity being maintained. For instance, while listening one should lean a little forward to show that they are interested in the conversation.
