Albert Mehrabian


Albert Mehrabian b. 1939

Engineer turned psychology professor Albert Mehrabian is best known for the research in the role of non-verbal communication which led to his 7-38-55 rule. This idea, that the words account for 7%, tone of voice for 38%, and body language accounts for 55% of liking, has been widely misunderstood and cited. He has served as consulting editor to Sociometry, Journal of Nonverbal Behavior, Journal of Personality and Social Psychology, and Journal of Psychology, and has authored or co-authored 20 books. Mehrabian’s experiments have helped identify nonverbal and subtle ways in which one conveys like-dislike, power and leadership, discomfort and insecurity, social attractiveness, or persuasiveness. His contributions include a three-dimensional mathematical model for the precise and general description and measurement of emotions and individual differences. Mehrabian is of much more value than his famous rule, finding much of interest such as that liars talk less and more slowly; and that people are more relaxed in the presence of someone of inferior status, and more most tense if their company has a perceived superior status.
