FUNDAMENTALS OF EMOTION
Basic Definition
- Emotion is a brief episode of coordinated responses including:
- Brain activation changes
- Behavioral modifications
- Autonomic system changes (heart rate, sweating, etc.)
- Can be triggered by external events (seeing a threat) or internal events (memories, thoughts)
Key Terms
- Feelings:
- The subjective experience of emotions
- Personal interpretation of emotional states
- Can vary between individuals
- Example: How one person experiences fear may differ from another
- Moods:
- Longer-lasting emotional states
- Lower intensity than acute emotions
- More sustained duration
- Example: Being in a "happy mood" vs. feeling intense excitement
- Interoception:
- The brain's ability to interpret bodily signals
- Integration of multiple physical responses
- Important for emotional awareness
- Includes processing of:
- Heart rate changes
- Muscle tension
- Temperature changes
- Breathing patterns
- Other bodily sensations
THEORIES OF EMOTION
1. James-Lange Theory
- Sequential process:
- Event occurs
- Physiological changes happen
- Brain interprets these changes
- Emotion is experienced
- Example:
- See a lion
- Heart races, muscles tense
- Brain notices these physical changes
- Person experiences fear
2. Cannon-Bard Theory
- More direct approach:
- Event simultaneously triggers emotion AND physiological changes
- No interpretation step needed
- More immediate than James-Lange theory
- Parallel processing rather than sequential
3. Cognitive Theory
- Two-factor approach:
- Physiological changes combine with
- Conscious awareness of the event
- Both factors needed to produce emotion
- Emphasizes role of cognition in emotional experience
4. Emergency Synthesis Theory
- Most current and accepted theory
- Features:
- Multiple pathways possible
- Some direct, some indirect
- More nuanced approach
- Flexible framework
- Accounts for individual differences
- Explains varying emotional responses
