When you are communicating, whether it is in a talk or a conversation, facial expressions are important. If someone pulls a face when drinking orange juice, you can see how sour the orange juice is. And you will almost be able to taste the sourness. That is, if the expression fits the taste.
Emotions are transferred through the facial expressions. You can see disgust, see sourness, see anger or see happiness. In fact: as an audience, you will feel the emotion.
This means that as a speaker, you can play with people’s emotions, using your face. It’s therefor important to pay attention to your facial expressions.
When you’re talking about something that is exciting, make sure your face is exciting! Smile when you are happy! When you’re talking about something sad… pull up a sad face… And of course, When you are talking about something angry, be angry!
Your audience will experience the emotion you are expressing.
There are exercises you can do to train showing emotions. I’ve added a few in the document attached to this article.
Try to test out the different emotions that you have in your presentation. And see how people respond. You will be surprised by the impact of your face.
