Introduction

• Examples of Emotional Outbursts: Mel Gibson, Tom Cruise, Kanye West.
• Role of Emotions:
  • Provide energy and motivation.
  • Often improve performance.
  • Affect how we think and behave.

Definition and Components of Emotion

• Emotion: Integrated mind-body response to a stimulus.
• Components:
  • Physiological arousal.
  • Expressive behaviors.
  • Conscious experience.
• Example: Feeling fear when followed at night.
• Key Questions:
  • Interaction of thinking and feeling?
  • Order of bodily reactions and thoughts?

Theories of Emotion

James-Lange Theory

• Proposed by: William James and Carl Lange.
• Concept: Physiological arousal precedes emotion (e.g., feel sad because you are crying).

Cannon-Bard Theory

• Proposed by: Walter Cannon and Philip Bard.
• Concept: Bodily responses and emotions occur separately but simultaneously.

Two-Factor Theory

• Proposed by: Stanley Schachter and Jerome Singer.
• Concept: Emotion requires physiological arousal and cognitive labeling.
• Experiment: College students injected with epinephrine and exposed to actors displaying emotions.

Zajonc’s View

• Proposed by: Robert Zajonc.
• Concept: Emotional reactions can occur separately, or before cognition.

Cognition and Emotion Interaction

• Pathways:
  • High-road: Complex emotions like love, involve cognitive processing.
  • Low-road: Quick, instinctive reactions bypassing the cortex.

Autonomic Nervous System and Emotion

• Sympathetic Division: Arouses body for action.
• Parasympathetic Division: Calms the body afterward.
• Optimal Arousal: Necessary for effective task performance.

Emotions and Brain Activity

• Overlap of Biological Signals: Different emotions can have similar physiological responses.
• Brain Patterns:
  • Positive feelings: More left frontal lobe activity.
  • Negative feelings: More right frontal lobe activity.
  • Fear: Increased amygdala activity.

Conclusion

• Importance of understanding emotions in daily life and interactions.
