Human communication is always three-dimensional. No spoken or written message is ever just words or rational thoughts. Every interchange between you and another person has and takes place at the following three intimately related levels, or dimensions, of being: emotional, physical, and rational. Any attempt to communicate will succeed if all of these dimensions are adhered to. Knowledge of this three-dimensional nature is the foundation of training. You can’t get much closer to real understanding without these realizations.
This knowledge is the basis for the use of practically any training device or medium you can name. For example, knowledge of the existence of and need for rational content is the elemental basis for outlining that attempt and understanding the various ways of doing so. Similarly, knowledge of the existence of and need for physical content is the basis and reason for the use of any form of audio-visual aid, graphics, illustrations, or other sensory communicative device. Finally, an underlying grasp of the existence of and need for emotional content is the basis for the use of what is commonly known as emotion appeal in communicating an idea.
Think about these three dimensions of communication before your next training session and you will most definitely see a difference.
