Becoming a better communicator is imperative to become more sensitive to others' body language and nonverbal cues, as well as our own.
The five roles are:
- Repetition: It strengthens the message you're making verbally.
- Contradiction: Avoiding contradictions is fundamental, so your listener knows you're telling the truth.
- Substitution: A facial expression can convey a far more clear message than words ever can, for example.
- Complementing: It can increase the impact of your message. Smiling to someone when you praise them is an excellent example of complementing.
- Accenting: It may emphasize a verbal message. Making a gesture, for example, can highlight the importance of your message.
