  • Conclusion: emotions like fear and confidence are contagious.

Non-verbal and Verbal Contagion

• Non-verbal Contagion Experiment:

  • Experiment in Portland: Vanessa looked up at nothing, causing others to mimic her action.
  • Conclusion: people catch emotions and rationalize them.

• Microexpressions:

  • Studied by Dr. Paul Ekman: universal expressions such as fear and happiness.
  • Fear expression enhances awareness and readiness.
