• 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.
1.5.1. Do’s of Body Language
• Be relaxed, calm and confident when you walk-in for starting a communication.
• Keep smiling in between as it shows that the person is confident and trustworthy.
• Stand or sit with a relaxed posture and straight spine.
• Keep your arms open and by your side when not communicating.
• Do hand shake, bow or namaste before you begin with the conversation.
• Make eye contact occasionally to show your level of involvement.
• Be a good listener and nod in between while listening.
• A little movement is necessary if you are giving a presentation.
• Place your feet firmly on the ground while moving during your presentation or addressing a gathering.
• Give a positive facial expression and try to be natural with your gestures.
