Chapter 12: Emotion, Stress, and Health Flashcards
Components of Emotion
physiological- changes in bodily arousal
cognitive- appraisal and interpretation of feeling
behavioral- expression of emotion
Physiological Component
changes in bodily arousal like increased heart rate, body temp, and respiration
produced by autonomic nervous system
difference in intensity of emotion relates to sympathetic nervous system (fight-or-flight). parasympathetic works to calm people down
Cognitive Component
- evaluative thoughts people have about their emotional experiences
- appraisal of events that are producing the emotion
influencing how intensely we will experience the emotion.
interpretation shapes how people experience the emotion
Behavioral
express emotion through body language
6 fundamental emotions: anger, sadness, happiness, surprise, fear, and disgust
3 Measurements of Emotions
behavioral displays of emotions
self-reports of emotions
psychophysiological reactions
Behavioral displays of emotion
observed by objective rater
actions, facial expressions
Self-rating of emotion
measure a person’s emotional experience
may be inaccurate and only provides limited feature
Physiological Reaction to stimuli
Facial Electromyography (EMG)- measures contraction of facial muscles. pleasant stimuli activates muscles involved in smiling. negative stimuli –> frowning
Heart Rate- unpleasant leads to lower heart rate, pleasant is associated with accelerated heart rate
Skin Conductance- high skin conductance -> more perspiration -> more arousal of emotion
Startle Reflex- measures involuntary movements like eye blinks
Cognitive Function of Emotions
help us organize our memories
help us prioritize our concerns and needs
may help us form judgement and make decision
Behavioral Function of Emotions
minimize negative emotions and maximize positive emotions
action tendencies
Social Functions of Emotions
emotions help coordinate relationships
can improve quality of emotions (sharing emotions can lead to intimacy and help form relationships)
James Lange Theory
- emotions. begins with perception of environment
- elicitation of physiological and behavioral change
- processed by the cortex and converted into emotion
appraisal lead to immediate physiological (SNS) reaction
typically leads to behavior
each emotion has unique SNS signature
people’s “experience” of emotion is an afterthought
ex. sam experienced high arousal and then interpreted it as anger
“I did not run because I was afraid. I felt afraid because I ran”
critic: predispose that every emotion has specific physiological response. fear of exam and fear of dog is different. not possible.
Cannon-Bard Theory
After perceiving an event, thalamus simultaneously relays information about event to sympathetic nervous system and to part of brain that perceive emotion
aka. experience of emotion and activation of sympathetic nervous system happen at the same time
Schachter and Singer’s Two-Factor Theory
- emotions. begins with perception of environment
- elicitation of physiological and behavioral change
- cognitive label of emotion
- feels a specific emotion
arousal in all emotions is the same. undifferentiated arousal of SNS. cognitive label turns undifferentiated arousal into a specific emotion
cognition determines whether the state of physiological arousal will be labeled as “anger”, “joy”, “fear”, etc.

Cognitive-Meditational Theory
aka Appraisal Theory
Richard Lazarus
cognitive appraisal affects how people interpret physical arousal and the level of arousal itself
Not afraid of bear in zoo because we can assess that it is of no danger.

Facial Feedback Theory
subjective experience of emotion are influenced by sensory feedback from facial muscle activity
facial efference- sensory feedback from facial muscular activity

Evolutionary Theory
emotional expression serve as communicative function that is essential to survival.
certain emotions have been passed down through generations because they have played a key role in survival
basic emotions: surprise, interest, joy, rage, fear, disgust, shame, and anguish
