Are they emotionally present and interested, or expressionless and dispassionate? Our face is remarkably communicative, able to deliver many emotions without uttering a single word. Moreover, unlike some forms of non-verbal communication, facial expressions are worldwide. The facial expressions of happiness, sadness, anger, surprise, fear, and disgust are the same across most nations. When presenting to an audience, you will need to consider whether your facial expressions convey your intended message to your listeners. Apart from feeling a wee tad silly doing the exercise, you have just proven to yourself that your facial expression contradicted what you said.
