Emotion: Theories, Biological Basis, and Cultural Influences (Psychology 1000, Chapter 11.4)

Emotion: Foundations and Components

Definition and Components of Emotion

Emotions are complex psychological states that involve subjective experience, physiological responses, and behavioral expressions. They are central to human experience and influence cognition, behavior, and social interaction.

• Subjective Perceptions: Emotions involve conscious and unconscious thoughts and appraisals.

• Energy: Emotional states are often accompanied by changes in energy levels and arousal.

• Brain/Body Reactions: Emotions are reactions to situations, involving both neural activity and physical changes.

• Behavioral Expression: Observable actions such as facial expressions or changes in muscle tension.

Example: Feeling fear when hearing a loud noise at night, accompanied by a racing heart and a startled jump.

Emotional States vs. Emotional Traits

• Emotional States: Transitory reactions that depend on specific situations.

• Emotional Traits: Consistent patterns of emotional reactions across various life situations.

The Biological Basis of Emotion

The Autonomic Nervous System (ANS) and Emotional Response

The ANS regulates involuntary physiological responses associated with emotions.

• Sympathetic Division: Prepares the body for stress ("fight or flight" response).

• Parasympathetic Division: Restores the body to normal conditions after stress.

Example: Increased heart rate and sweating during fear or excitement.

Fear and the Autonomic Response

• Brain-Body Reaction: Can be conscious or unconscious.

• Unconscious Processing: The brain can execute a reaction to fear before conscious awareness.

• Two Pathways for Processing Fear:

  • Low Road: Fast, unconscious processing via the amygdala.

  • High Road: Slower, conscious processing via the sensory cortex.

Diagram Description: Emotional stimulus is sensed by the thalamus, which can send signals via the "low road" to the amygdala (quick alarm) or via the "high road" to the sensory cortex for detailed analysis.

Contemporary Model of Emotion

Integrated Components

Modern models of emotion recognize the interplay between physiological arousal, behavioral tendencies, emotional expression, and subjective feelings.

• Appraisal: Cognitive evaluation of an emotional stimulus.

• ANS Arousal: Activation of the autonomic nervous system.

• Behavioral Tendency: Inclination to act in response to emotion.

• Emotional Expression: Outward display of emotion.

• Emotional Feelings: Subjective experience of emotion.

Theories of Emotion

James-Lange Theory

This theory posits that physiological responses to stimuli precede and give rise to the subjective experience of emotion.

• Sequence: Event → Physiological response → Emotional experience.

• Example: Heart races → Feel afraid.

Cannon-Bard Theory

Disagrees with James-Lange, suggesting that emotional feelings and physiological responses occur simultaneously and independently.

• Sequence: Event → Simultaneous emotional and bodily response.

• Example: Hear a noise → Heart races and feel fear at the same time.

Two-Factor Theory (Schachter-Singer)

Proposes that emotion is determined by physiological arousal and the cognitive interpretation (appraisal) of that arousal.

• Sequence: Physiological arousal + Cognitive label → Emotional experience.

• Example: Heart races (arousal) + "I am in danger" (cognitive label) → Feel fear.

Universality and Cultural Influences on Emotion

Are Emotions Universal?

Some emotions are considered universal, experienced across cultures and hardwired into human biology.

• Basic Emotions: Joy, Surprise, Sadness, Anger, Disgust, and Fear.

• Physiological Distinctiveness: Each basic emotion has unique physiological markers.

Culture and Emotions

While basic emotions are universal, cultural factors influence how emotions are expressed and regulated.

• Display Rules: Culturally specific guidelines for when, how, and where emotions should be expressed.

• Examples:

  • Western societies: Boys are discouraged from crying.

  • Eastern societies: Emphasis on restraint and deference to authority.

Emotional Dialects

Variations in emotional expression across cultures, even for the same emotion.

• Example: Contempt is expressed by lowering the brow in North America, but by raising the upper lip in Gabon (West Africa).

Display Rules (Expanded)

• Definition: Unwritten cultural expectations and etiquette for emotional expression.

• Function: Dictate when, how, and why emotions are expressed or suppressed.

Summary Table: Major Theories of Emotion

Theory	Main Idea	Sequence of Events	Key Example
James-Lange	Emotion follows physiological response	Stimulus → Physiological response → Emotion	Heart races, then feel fear
Cannon-Bard	Emotion and physiological response occur simultaneously	Stimulus → Emotion + Physiological response	Heart races and feel fear at the same time
Two-Factor (Schachter-Singer)	Emotion is a combination of arousal and cognitive interpretation	Arousal + Cognitive label → Emotion	Heart races, interpret situation as dangerous, feel fear

Key Terms and Definitions

• Emotion: A complex psychological state involving subjective experience, physiological response, and behavioral expression.

• Autonomic Nervous System (ANS): Regulates involuntary bodily functions and is involved in emotional responses.

• Sympathetic Division: Part of the ANS that prepares the body for stress.

• Parasympathetic Division: Part of the ANS that restores the body to normal after stress.

• Display Rules: Cultural norms dictating how and when emotions are expressed.

• Emotional Dialects: Culturally specific ways of expressing the same emotion.

Formulas and Diagrams

• James-Lange Theory: $\text{Stimulus} \rightarrow \text{Physiological Response} \rightarrow \text{Emotion}$

• Cannon-Bard Theory: $\text{Stimulus} \rightarrow \text{Emotion} + \text{Physiological Response}$

• Two-Factor Theory: $\text{Emotion} = \text{Arousal} + \text{Cognitive Label}$
