Nonverbal Communication

This section explains the principles of nonverbal communication, types of nonverbal communication, movement when giving a speech, and strategies you can use to improve your nonverbal communication.

Principles of Nonverbal Communication

Nonverbal Communication Is Fluid

Chances are you have had many experiences where words were misunderstood, or where the meaning of words was unclear. When it comes to nonverbal communication, meaning is even harder to discern. You can sometimes tell what people are communicating through their nonverbal communication, but there is no foolproof "dictionary" of how to interpret nonverbal messages.

Nonverbal communication is the process of conveying a message without the use of words. It can include gestures and facial expressions, tone of voice, timing, posture and where you stand as you communicate. It can help or hinder the clear understanding of your message, but it doesn't reveal (and can even mask) what you are really thinking. Nonverbal communication is far from simple, and its complexity makes your study and your understanding a worthy but challenging goal.

Nonverbal communication involves the entire body, the space it occupies and dominates, the time it interacts, and not only what is not said, but how it is not said. Confused? Try to focus on just one element of nonverbal communication and it will soon get lost among all the other stimuli. Consider one element, facial expressions. What do they mean without the extra context of chin position, or eyebrows to flag interest or signal a threat? Nonverbal action flows almost seamlessly from one movement to the next, making it a challenge to interpret one element, or even a series of elements. How well can you correctly identify the feelings behind facial expressions?

You may perceive time as linear, flowing along in a straight line. You do one task, you're doing another task now, and you are planning on doing something else all the time. Sometimes you place more emphasis on the future, or the past, forgetting that you are actually living in the present moment whether you focus on "the now" or not. Nonverbal communication is always in motion, as long as you are, and is never the same twice.

Nonverbal communication is irreversible. In written communication, you can write a clarification, correction, or retraction. While it never makes the original statement go completely away, it does allow for correction. Unlike written communication, oral communication may allow "do-overs" on the spot: you can explain and restate, hoping to clarify your point. In your experience, you've likely said something you would give anything to take back, and you've learned the hard way that you can't. Oral communication, like written communication, allows for some correction, but it still doesn't erase the original message or its impact. Nonverbal communication takes it one step further. You can't separate one nonverbal action from the context of all the other verbal and nonverbal communication acts, and you can't take it back.

In a speech, nonverbal communication is continuous in the sense that it is always occurring, and because it is so fluid, it can be hard to determine where one nonverbal message starts and another stops. Words can be easily identified and isolated, but if you try to single out a speaker's gestures, smile, or stance without looking at how they all come together in context, you may miss the point and draw the wrong conclusion. You need to be conscious of this aspect of public speaking because, to quote an old saying, "Actions speak louder than words". This is true in the sense that people often pay more attention to your nonverbal expressions more than your words. As a result, nonverbal communication is a powerful way to contribute to (or detract from) your success in communicating your message to the audience.
