Slow down and present your most basic information first before elaborating on any details. This ensures a basic understanding of the topic presented.
Use appropriate tones and body language to convey how you feel about a subject and its importance. A monotone voice and stiff countenance express disinterest and lack of investment in topics.
Use eye contact to establish a direct connection with the person or persons you are communicating with, if possible. Eye contact conveys interest in your listener and her take on topics.
Ask questions to determine that the person receiving your communications understands, and respond accordingly. Questions show that you care if your listener understands the topic.
Encourage the contribution of ideas from whoever you are communicating with. Facilitating, considering and even accepting ideas shows your concern and interest in your listener.
Recieving or Listening
Listen actively; ask questions when you need clarification, and respond in some way when you understand or even when you don't. Active listening conveys your interest in the speaker and encourages him to speak frankly and freely.
Express a willingness to listen to and even consider new ideas or ways of doing things. Considering the speaker's ideas shows that you value her thoughts and opinion; this strengthens your communication relationship.
Tell the speaker your opinion; try to do this as constructively as possible. Responding is evidence that you have listened and consider the speaker's address important and worth considering.
