Those who study the communication process identify five key components of communication: 1. STIMULUS -- some event or action that creates a need to communicate. For example, you've just been promoted -- you need to tell someone! Or, you witness a crime -- the police want as much information as you can provide. 2. FILTER -- each person's unique impression of reality. We all bring a set of filters and biases to each situation; they determine how we "see" things and how we react to them. Since no two of us have had _exactly_ the same life experiences, we each bring a different perspective to things. Language is comprised of hundreds of words that can mean different things to different people. Some common filters include: age, gender, education level, status or authority levels, past experience, level of knowledge about the subject matter. 3. MESSAGE -- composed of verbal and non-verbal symbols, this is the information you're trying to transmit. Words alone are often not enough -- we use body language, volume of voice, pace, tone, color, formatting tools and a host of other techniques to help insure that our message is understood. 4. MEDIUM -- the form the message takes -- oral or written; verbal or non-verbal. 5. DESTINATION -- as our message enters the sensory environment of the receiver, control passes from the sender to receiver. All communication requires a Sender and a Receiver. Problems with the communication process can originate with either person. There are two basic forms of communication: one-way and two-way. An example of one-way is this lecture -- I type, you read -- right now there's nothing else happening.
