So as well as looking at techniques and procedures for such occasions as farm visiting, demonstrating and leading discussions, we shall need to look inside our own and other heads and explore a little psychology-a teaspoonful rather than a cupful-in order to understand more clearly those thoughts and feelings that can easily become blockages to communication. THE CHARACTERISTICS OF GOOD COMMUNICATION To summarize the ideas presented in this opening chapter-and to establish some basic principles which underlie all that is said throughout this manual-here is a list of characteristics: 1. Good communication is the result of clear thinking. 2. Good communication has a specific purpose and carries specific messages. 3. Good communication is adapted to the occasion-to the needs and interests of those receiving it. 4. Good communication utilizes an appropriate medium. 5. Good communication is graphic-through words or pictures it creates clear, accurate images in the minds of those who are receiving it. 6. Good communication is based on good listening.
