What and Why of Emotions
Emotions– A feeling state involving physiological arousal, a
cognitive appraisal of the situation arousing the state, and an outward expression of the state
Explaining the components of emotions– Typically, psychologists have studied emotions in
terms of three components-the physical, the cognitive, and the behavioral
– The physical component is the physiological arousal that accompanies the emotion

What and Why of Emotions
Explaining the components of emotions (continued)– The cognitive component determines the specific
emotion we feel– The behavioral component of emotions is the
outward expression of the emotions

What and Why of Emotions
Theories of emotion– James-Lange theory of emotion
The theory that emotional feelings result when an individual becomes aware of a physiological response to an emotion-provoking stimulus
– Cannon-Bard theory of emotion The theory that an emotion-provoking stimulus is
transmitted simultaneously to the cortex, providing the feeling of emotion, and to the sympathetic nervous system, causing the physiological arousal
– Schachter-Singer theory of emotion A two-stage theory stating that for an emotion to occur,
there must be (1) physiological arousal and (2) an explanation for the arousal

What and Why of Emotions
Theories of emotion (continued)– Lazarus theory of emotion
The theory that an emotion-provoking stimulus triggers a cognitive appraisal, which is followed by the emotion and the physiological arousal

What and Why of Emotions
Emotion and the brain– The brain structure most closely associated with
fear is the amygdala– When the emotion of fear first materializes, much of
the brain’s processing is nonconscious
Copyright © 2007 Horizon Textbook Publishing All rights reserved
What and Why of Emotions
Emotion and the brain (continued)– Researchers using electroencephalographs to track
mood changes have found that reductions in both anxiety and depression are associated with a shift in electrical activity from the left to the right side of the brain
Polygraph test– A device designed to detect changes in heart rate,
blood pressure, respiration rate, and the skin conductance response that typically accompany the anxiety that occurs when a person lies
Copyright © 2007 Horizon Textbook Publishing All rights reserved
What and Why of Emotions
Polygraph test (continued)– Assumption behind the polygraph examination is
that lying causes changes in these physiological function s that can be accurately measured and recorded by the device
– However, a polygraph is not really a lie detector; it cannot distinguish lying from fear, sexual arousal, anxiety, anger, or general emotional arousal
– Lykken Found that increasing arousal by tensing muscles and
thinking about something exciting during neutral questions could also alter the results

To Tell the Truth
How to detect deception– Hand gestures decrease– Hand to face gestures increase
Mouth guard Nose touching Rubbing eye Neck scratch Ear rub
– Body shifts increase– Less eye contact– More foot movement– More speech errors– Pitch of voice increases (goes higher)

“To Tell the Truth” It is your job to detect who is not telling the truth. Now that you know what to look for with regard to nonverbal cues of deception listen to your classmates answer the following questions. Have them lie on tow of the questions and try to determine which two they are lying.
1. In what month is your birthday?2. How many siblings do you have?3. What is the last digit of your student I.D. number?4. What is your middle name?5. What is your favorite color?6. What is your father’s first name?7. To which political party do you subscribe?8. What were you born?9. How old are you?10. What is your shoe size?11. Have you ever been given a speeding ticket?12. How well do you play tennis?

Expression of Emotion
Range of emotion– Paul Ekman and Carroll Izard
Insist that there are a limited number of basic emotions
– Basic emotions Emotions that are found in all cultures, that are reflected in
the same facial expressions across cultures, and that emerge in children according to their biological timetable
– Ekman Suggested considering emotions as families Anger family might range form annoyed to irritated, angry,
livid, and finally enraged If perceived as a family, anger should also include various
forms of its expression

Expression of Emotion
Range of emotion (continued)– Ekaman and Friesen
Claim there are subtle distinctions in the facial expression of a single emotion that convey its intensity
Development of facial expressions– Like the motor skills of crawling and walking, facial
expressions of emotions develop according to a biological timetable of maturation
– Consistency of emotional development across individual infants and across cultures supports the idea that emotional expression is inborn

Expression of Emotion
Universality of facial expressions– Charles Darwin
First to study the relationship between emotions and facial expressions
Believed that the facial expression of emotion was an aid to survival, because it enabled people to communicate their internal states and react to emergencies before they developed language
Maintained that most emotions, and the facial expressions that convey them, are genetically inherited and characteristic of the entire human species
Concluded that facial expressions were similar across cultures

Expression of Emotion
Universality of facial expressions (continued)– Scherer and Wallbott
Found very extensive overlap in the patterns of emotional experiences reported across cultures in 37 different counties on 5 continents
Also found important cultural differences in the ways emotions are elicited and regulated and in how they are shared socially
– Researchers found that Caucasian Americans more quickly identified the facial expressions of other Caucasian Americans than did Caucasian Europeans

Expression of Emotion
Cultural rules for displaying emotion– Display rule
Cultural rules that dictate how emotions should be expressed, and when and where their expression is appropriate
– Often a society’s display rules require people to give evidence of certain emotions that they may not actually feel or to disguise their true feelings
– Cole Found that 3-year-old girls, when given an unattractive gift,
smiled nevertheless They had already learned a display rule and signaled an
emotion they very likely did not feel

Expression of Emotion
Cultural rules for displaying emotion (continued)– Davis
Found that among first to third graders, girls were better able to hide disappointment than boys were
– Not only can emotions be displayed by not felt, they can also be felt but not displayed
– Most of us learn to display rules very early and abide by them most of the time

Expression of Emotion
Emotion as a form of communication– Katherine Bridges
Observed emotional expression in Canadian infants over a period of months
Reported that the first emotional expression to appear is that of distress
– Researchers have found that mothers in many cultures attempt to regulate the moods of their babies through facial communication of emotions
Copyright © 2007 Horizon Textbook Publishing All rights reserved
Expression of Emotion
Emotion as a form of communication (continued)– In a study involving some 200 male and female
university students, women admitted that they flirted with, smiled at, and played up to men, leading them on when they had no romantic interest in the men or any intention of having sex with them
– Men admitted intentionally deceiving women about the depth of their emotional commitment

Experiencing Emotion
Facial-feedback hypothesis– Sylvan Tomkins
Claimed that the facial expression itself-that is, the movement of the facial muscles producing the expression-triggers both the physiological arousal and the conscious feeling associated with the emotion
– Facial-feedback hypothesis The idea that the muscular movements involved in certain
facial expressions trigger the corresponding emotions
Copyright © 2007 Horizon Textbook Publishing All rights reserved
Experiencing Emotion
Facial-feedback hypothesis (continued)– Ekman and colleagues
Documented the effects of facial expressions on physiological indicators of emotion using 16 participants
Reported that a distinctive physiological response pattern emerged for the emotions of fear, sadness, anger, and disgust, whether the participants relived one of their emotional experiences or simply made the corresponding facial expression
Researcher found that both anger and fear accelerate hear rate, but fear produces colder fingers than does anger
Copyright © 2007 Horizon Textbook Publishing All rights reserved
Experiencing Emotion
Facial-feedback hypothesis (continued)– Izard
Believes that learning to self-regulate emotional expression can help in controlling emotions
Proposes that this approach to the regulation of emotion might be a useful adjunct to psychotherapy
Gender differences in experiencing emotion– David Buss
Has reported that women are far more likely to feel anger when their partner is sexually aggressive
Men experience grater anger than women when their partner withholds sex
Copyright © 2007 Horizon Textbook Publishing All rights reserved
Experiencing Emotion
Gender differences in experiencing emotion (continued)– Research by evolutionary psychologists also
suggests clear and consistent differences between the sexes concerning feelings of jealousy
– Men, more than women, experience jealousy over evidence or suspicions of sexual infidelity
– A women is more likely than a man to be jealous of her partner’s emotional attachment and commitment to another and over the attention, time, and resources diverted from the relationship

Experiencing Emotion
Emotion and cognition– Emotion allows us to detect risk more quickly than
we could with rational though alone– It is possible that the anger-optimism link arises
from confidence, whether justified or not, in concrete measures directed towards people who are perceived as potentially threatening

Experiencing Emotion
Love– Triangular theory of love
Robert Sternberg’s theory that three components-intimacy, passion, and decision/commitment-singly and in various combinations produce sever different kinds of love
– Liking– Infatuated love– Empty love– Romantic love– Fatuous love– Companionate love– Consummate love
