How prevalent is Non verbal Behaviour?
Some researchers put the level of nonverbal communication as high as 80 percent of all communication. More reasonably it could be at around 50-65 percent. That’s exactly what Mehrabian discovered in his communication study. He found that only 7 percent of communication comes from spoken words, 38 percent is from the tone of the voice, and 55 percent comes from body language. However, Mehrabian was only referring to cases of expressing feelings or attitudes, such as when a person says "I do not have a problem with you!" when people commonly focus on the tone of voice, and body language of the person, rather than the actual words said. It is a common misconception that these percentages apply to all communication.
