Yes, and it is written in Charles Darwin’s “The Expression of the Emotions in Man and Animals,” facial expressions are a universal way to convey emotions, but they can differ according to culture. The seven universal micro expressions are:
• Anger
• Fear
• Sadness
• Happiness
• Surprise
• Disgust
• Contempt
These only occur for 1/15 or 1/25 seconds and are the best indicators of someone’s emotions.
