Lecture on Emotions

Introduction

• Famous examples of public emotional outbursts by celebrities (e.g., Mel Gibson, Tom Cruise, Kanye West)

Theories of Emotion

James-Lange Theory

• Proposed by William James and Carl Lange
• Suggests emotions follow bodily reactions
• Example: Sad because crying, scared because shaking

Cannon-Bard Theory

• Proposed by Walter Cannon and Philip Bard
• Emotions and bodily responses occur simultaneously but separately

Two-Factor Theory (Schachter & Singer)

• Emotions involve physiological arousal and cognitive labeling of that arousal
• Spillover Effect: Arousal from one event can influence response to another event
• Famous experiment with epinephrine and emotional labeling

Zajonc's View

• Emotions can occur without cognitive processing
• Automatic emotional reactions occur before cognition

Cognition and Emotion

• Cognition plays a role in defining emotion
• Interpretation of stimuli affects emotional response
• Top-Down vs. Bottom-Up Processing:
  • Complex emotions require cognitive processing (high-road)
  • Simple reactions bypass cognitive processing (low-road)

Autonomic Nervous System

• Sympathetic Division: Arouses in crisis (increased heart rate, breathing, energy)
• Parasympathetic Division: Calms after crisis
• Balance of arousal is crucial for optimal function

Biological Signals of Emotion

• Overlapping symptoms for different emotions
• Brain activity patterns differ for positive and negative emotions
• Amygdala activity increases with fear

Importance of Understanding Emotions

• Emotions drive behavior and decision-making
• Misreading emotions can be confusing and dangerous

Conclusion

• Emotions are essential and complex
• Various theories explain different aspects of emotional experience
