Answer:
The emotional state of jealousy was not identified by Paul Ekman as having a universal facial expression.
Paul Ekman is a well-known psychologist who has extensively studied facial expressions and emotions. He has identified six basic emotions that are universally expressed through facial expressions across different cultures and languages. These six emotions are happiness, sadness, anger, fear, surprise, and disgust.
Jealousy is not one of the six basic emotions identified by Paul Ekman. While jealousy is a common emotion experienced by many people, its expression may vary across different cultures and may not be universally recognizable through facial expressions alone.
