Where Do Our Facial Expressions Come From?

The video explores the universality and innateness of facial expressions, tracing back to Darwin's theories and Ekman's cross-cultural research. It introduces the Facial Action Coding System (FACS) for measuring expressions and discusses the evolutionary role of expressions in sensory input and survival. The video also highlights the balance between innate expressions and learned social cues.

What did Darwin propose about the origin of human emotional expressions?

• They are developed through personal experiences.

• They are unique to each individual and not universal.

• They are inherited from our ancestors and aid in survival.

• They are learned behaviors from cultural interactions.

What was the main finding of Paul Ekman's research in New Guinea?

• Facial expressions are learned through social interactions.

• Facial expressions are unique to each culture.

• Isolated cultures use different expressions for emotions.

• Basic facial expressions are universal across cultures.

What is the purpose of the Facial Action Coding System (FACS)?

• To teach people how to express emotions.

• To document and measure muscle activity in facial expressions.

• To create new facial expressions for different emotions.

• To eliminate the need for verbal communication.

How do facial expressions help us react to our environment?

• By reducing the need for physical movement.

• By making us more attractive to others.

• By increasing our ability to communicate verbally.

• By controlling sensory input like light and smell.

What is the learned component of facial expressions?

• The development of new expressions for new emotions.

• The ability to express emotions universally.

• The control and masking of emotions in social settings.

• The innate nature of basic facial expressions.
