Physiological Response
Brain structure activity (RAS, thalamus, amygdala)
Right prefrontal cortex: NALeft prefrontal cortext: PA
ANS, facial expressionHeart rate, blood pressure, countenanceBlood flow to hands greater w/ anger than sadness
Endocrine system/hormonal activityAdrenaline, cortisol

Cognitive Response
Evaluate potential consequences of event & your ability to cope
AppraisalDo I care about what is happening here?
Might this prevent (help) me from reaching my goals?
Interpret physiological changesHow upset/excited am I?

Behavioral Response
Adaptive behaviors Reduce negative &
increase positive valence
Express emotionFacial features/body
language/tone of voice Informs others about
current emotional state
Can we determine emotions via faces?
Grab a partner & make a face!

Emotions
Emotions unites all these diverse responses into a coherent response systemAdaptive response to some event

Reaction Paper VIII: Emotion
What do you think causes emotions? Provide a novel example of this cause for one specific emotion (e.g., anger, happiness, fear).
PLEASE TURN THIS IN AFTER CLASS!

Biological Paradigm - Zajonc
Emphasize evolution/adaptive nature of emotion
Changes in physiology, facial expressions, cortical activity produce emotions
Genetically inherited neural circuits Biology primary
No cognition needed
![Page 17: Emotion A Multidimensional Response System. Nature of emotions ßMultidimensional, adaptive response system ßPhysiological ßConscious (subjective feelings)](https://reader035.vdocuments.us/reader035/viewer/2022062712/56649c6e5503460f949209bd/html5/thumbnails/17.jpg)
Biological Paradigm - Zajonc
Stimulate amygdalaEmotional R
Manipulate facial musclesEmotional R
Emotions are often fast/automaticSomeone jumps out and
scares you --> fearNo time for thought
Emotions precede cognition in development Infants emotional?,
cognitive?

Biological Paradigm - Theories James-Lange Theory
Emotion = awareness of physiological responses to emotion-arousing stimuli‘We are sad because we cry, afraid because we tremble.’
Fear(emotion)
Poundingheart
(arousal)
Sight of oncoming
car(perception of
stimulus)

Cognitive Paradigm - Lazarus
Emotion = person-event relationshipCognitive interpretations
establishes nature of that relationship
Depends on whether event potentially impacts one’s goals
Appraisals keyW/o cognitions, no

Must not have prior explanation of arousal

Biological or Cognitive paradigm? Who is right?
Is cognition primary or is biology primary in emotions?
BOTH!Evolutionarily devised quick response systemSlower cognitive processing system
These probably interact in complex ways

Two-Systems viewSystem 1
Innate automatic system reacts w/o higher processing to emotional SThalamus-> Amygdala
System 2Experience based system
dependent on new learning & cognitive processingCortex
Culture/life experience plays a role in emotions

Experiencing Emotion
Subjective Well-BeingSelf-perceived happiness or satisfaction with lifeUsed along with measures of objective well-being
Physical and economic indicators to evaluate people’s quality of life
Love (need to belong) more important than $

Happiness is...
Researchers Have Found ThatHappy People Tend to
Have high self-esteem (in individualistic countries)
Be optimistic, outgoing, and agreeable
Have close friendships or a satisfyingmarriage
Have work and leisure that engagetheir skills
Have a meaningful religious faith
Sleep well and exercise
However, Happiness Seems Not MuchRelated to Other Factors, Such as
Age
Gender (women are more often depressed, but also more often joyful)
Education levels
Parenthood (having children or not)
Physical attractiveness
