• There is no prerequisite of learning a specific language and can be used by people in different geographical
              areas with different cultures.

            Disadvantages of Visual Communication
            Some of the disadvantages of visual communication are:
               • It is an expensive medium of communication as it requires the additional cost and time for designing and
              printing pamphlets, posters, pictures, etc.
               • It is a time-consuming process as designing and decorating takes more time than writing or conveying orally.
               • Visuals alone are not a complete way of delivering meaningful information. It needs other forms like verbal and
              non-verbal to complete its communication.

               • It is a specific skill which cannot be used everywhere and in all situations.

            1.5. IMPACT OF BODY LANGUAGE

            Body Language  is a very important  part of non-verbal
            communication that reveals your true thoughts and emotions. It
            includes gestures, body postures, movements and expressions
            to convey our message in a group or to an individual.

            Albert Mehrabian, Professor of Psychology at the University
            of California, did research on body language  in the 1950s
            and he found that the total impact of a message is about 7%
            verbal (words only) and 38% vocal (tone of voice, pauses and
            other sounds) and 55% non-verbal using body gestures, body
            postures, movements and expressions. The five main elements
            of the body language are:

               • Facial expression
               • Body movement and posture
               • Gestures
               • Eye contact
               • Touch

            Positive and right body language creates a sense of confidence and helps you gain the attention of your audience
            even if you need to fake it initially. Learning this skill allows you to make positive changes in your behaviour and
            this leads to better outcomes.
            Let us now study some of the do’s and don’ts for positive impact of body language on the people around us.

               • Be a good listener and nod in between while listening.
               • A little movement is necessary if you are giving a presentation.
