Emotion, Stress, and Coping 1
Emotion
- Emotions reflect a "stirred up’ state
- Emotions have valence: positive or negative
- Emotions are thought to have 3 components:
- Physiological arousal
- Subjective experience
- Behavioral expression
James-Lange Theory of Emotion

Assessment of James-Lange Theory of Emotion
- Cannon’s arguments against the theory:
- Visceral response are slower than emotions
- The same visceral responses are associated with many emotions (increased heart rate with anger and joy).
- Subsequent research provides support:
- Different emotions are associated with different patterns of visceral activity
- Accidental transection of the spinal cord greatly diminishes emotional reactivity (prevents visceral signals from reaching brain)
Subjective Emotional Experience
- Emotional intensity varies along a bell curve
- At the upper end are people with severe personality disorders (too intense anger and sadness)
- At the lower end are people who appear not to have emotional states
- "Alexithymia" a condition in which a person does not experience emotional states
Happiness as an Emotion
- Happiness is an emotional state characterized by a positive valence
- Research shows that happiness is
- related to cultural values (highest in individualistic cultures, lowest in collectivist cultures)
- not related to:
- Gender
- Age
- Individual wealth

Facial Expression of Emotion
- There is an evolutionary link between the experience of emotion and facial expression of emotion:
- Served to inform others of our emotional state
- Different facial expressions are associated with different emotions
- Facial expression can alter emotional experience

Taxonomy of Emotions
- How many basic emotional states?
- Between 5 and 9 basic states:
- The common 5 include anger, fear, happiness, sadness, and disgust
- Additional states include surprise, contempt, shame, guilt, joy, and trust
- Emotional valence may be related to activity in the nervous system:
- Positive: activity of dopamine systems
- Negative: activity of norepinephrine systems

Cognitive Perspectives on Emotion
- Plato: "reason must rein in the passions"
- Schachter and Singer (1962): cognitive judgements are a critical part of emotional experience:
- Subjects are aroused by an injection of adrenaline and then exposed to anger or happiness cues
- The emotional cues played a prominent role in emotional experience

Emotional Influences on Cognition
- Emotional states can alter our cognitive ability
- Anxiety can reduce working memory capacity by the process of distraction
- Mood can alter the way we make judgements, inferences, or predictions
- Mood becomes a part of memory and can alter encoding/retrieval of information
- Extreme emotional experiences can alter brain structure
Stress
- Stress: A state that impairs our ability to respond to internal and external demands
- Stress is a psychobiological process
- Stress reflects the interaction of the person with their environment
- Stress responses are organized in stages
- Alarm: release of adrenaline and activation of the autonomic nervous system
- Resistance: all systems return to normal
- Exhaustion: systems begin to fail
Modern Views of Stress
- Richard Lazarus: stress is a transaction between a person and their environment
- Primary appraisal: person evaluates situations as benign or stressful
- Secondary appraisal: person decides how to deal with stress
- Lazarus identifies three types of stress:
- Loss: person loses a loved one or a possession
- Threat: anticipated harm
- Challenge: opportunity for growth (new job)
