James-Lange Theory
  • Stimulus leads to physiological response leads to emotion
  • Physiological response comes first before the emotion
  • Example: oncoming car leads to pounding heart which leads to feeling of fear

Cannon-Bard Theory
  • Stimulus leads to both the physiological response and the feeling of emotion
  • Physiological response and emotion occur simultaneously
  • One does not cause the other
  • Example: oncoming car leads to both pounding heart and feeling of fear at the same time

Two-Factor Theory
  • Stimulus leads to physiological response and cognitive label which leads to emotion
  • Physiological response requires our cognition (perceptions, memories, interpretations) in order to create emotion
  • Example: oncoming car leads to pounding heart and cognitive label of “I’m afraid” leads to feeling of fear
