Feelings, emotions and attitudes tend to make clear communication a considerable challenge. We communicate with our "hearts" as much as we do with our "heads." Communication is not simply logical; it is psychological. It involves not only logic, facts, figures, the brain, the mind, butalso feelings, attitudes, emotions... thewhole person. For instance, if you like the person who is speaking, you will tend to accept what that person says more readily and more positively than you would accept a similar message from someone you detest. You tend to give different meaning to a comment from "the boss" than you would give to a similar comment coming from a co-worker. You are very likely to interpret things said by a beautiful woman differently than you would interpret the same thoughts coming from a bum. The very same words (such as, "Go jump in the lake') can have different meanings, depending on whether they are said jokingly, matter-of-factly, or angrily. Communication is a two-way process that involves the sending and receiving of symbols, signs, or signals (words, pictures, things, actions). It is speaking and listening, writing and reading, behaving and observing behavior. Its goal is to achieve understanding. Perhaps this is the simplest, most practical, easiest-to-remember definition:
