The view that human emotions are universal has been supported by the studies of

Paul Ekman

Ekman conducted a series of studies through which he found that there are six basic human emotions that are found globally across cultures and geography. These emotions are:

1. Anger

2. Disgust

3. Fear

4. Surprise

5. Happiness

6. Sadness

Ekman claimed that these universal emotions are primarily expressed through facial expressions.
