Motivation and emotion

Motivation and Emotion



  • Instinct Theory: we are motivated by our inborn automated behaviors.

  • But instincts only explain why we do a small fraction of our behaviors.

Drive reduction theory

Drive Reduction Theory

  • Our behavior is motivated by BIOLOGICAL NEEDS.

  • Wants to maintain homeostasis.

  • When we are not, we have a need that creates a drive.

  • Primary versus Secondary drives

Arousal theory

Arousal Theory

  • We are motivated to seek an optimum level of arousal.

  • Yerkes-Dodson Law

Yerkes dodson law

Yerkes-Dodson Law

  • The Yerkes-Dodson Law says we perform best under the optimal amount of arousal. (Like Goldilocks)

  • Not too much, not too little.

Maslow s hierarchy of needs

Maslow’s Hierarchy of Needs

  • Abraham Maslow said we are motivated by needs, and all needs are not created equal.

  • We are driven to satisfy the lower level needs first.

Motivation of hunger

Motivation of HUNGER

Biological basis of hunger

Biological Basis of Hunger

  • Hunger does NOT come from our stomach.

    It comes from our…

  • Brain

    What part of the brain?

  • The Hypothalamus



Lateral Hypothalamus

Ventromedial Hypothalamus

When stimulated you feel full.

When lesioned you will never feel full again.

  • When stimulated it makes you hungry.

  • When lesioned (destroyed) you will never be hungry again.

I’m late for lunch. I’m hungry. The lateral hypothalamus makes you hungry.

Set point theory

Set Point Theory

  • The hypothalamus acts like a thermostat.

  • Wants to maintain a stable weight.

  • Activate the lateral when you diet and activate the ventromedial when you start to gain weight.

  • Leptin theory

Body chemistry

Body Chemistry

  • Glucose

  • The hormone insulin converts glucose to fat.

  • When glucose levels drop- hunger increases.

Psychological aspects of hunger

Psychological Aspects of Hunger

  • Internals versus Externals

  • The Garcia Effect

Fried Frog Legs

Criadillas- bull testicles.

Eating disorders

Eating Disorders

Bulimia Nervosa

  • Characterized by binging (eating large amounts of food) and purging (getting rid of the food).

Anorexia nervosa

Anorexia Nervosa

  • Starve themselves to below 85% of their normal body weight.

  • See themselves as fat.

  • Vast majority are women.



  • Severely overweight to the point where it causes health issues.

  • Mostly eating habits but some people are predisposed towards obesity.

Click on the pictures to see some case studies on obesity.

Sexual motivation

Sexual Motivation

  • Sex is natural.

  • Without sex, none of us would be here.

  • How do scientists (or you) find out about sex?

    YOU ASK!!!!!!

Kinsey s studies

Kinsey’s Studies

  • Confidential interviews with 18,000 people (in early 1950’s).

  • Sexual Behavior in the Human Male and Sexual Behavior in the Human Female

  • Scale of sexuality….0 to 6 where 0 is exclusively heterosexual and 6 homosexual and 7 is asexual.

Click on Kinsey to see the movie trailer.

Masters and johnson study

Masters and Johnson Study

  • In the 1960’s William Masters and Virginia Johnson set out to explore the physiology of sex.

  • 382 females and 312 males.

After their research was done they ran an institute that claimed to turn gay people straight.

Mapped out the sexual response cycle

Mapped out the Sexual Response Cycle

  • Initial Excitement

  • Plateau Phase

  • Orgasm

  • Resolution Phase (with refractory period).

Psychological factors in sexual motivation

Psychological Factors in Sexual Motivation

  • Only some people are externals when it comes to hunger- but we are all externals when it comes to sex.

  • Heiman 4 tape study.

  • People can find sexually explicit images either pleasing or disturbing- but they are none the less biologically arousing.

We have discussed the energizing of sexual motivation but have yet to discuss its direction

We have discussed the energizing of sexual motivation but have yet to discuss its direction:

Sexual Orientation

An enduring sexual attraction toward members of either one's own gender or the other gender.

How is sexual orientation determined

How is Sexual Orientation Determined

  • There has been NO evidence that sexuality is socially determined.

  • Kids raised by gay parents are no more likely to be gay that if they were raised by hetero parents.

  • This it is likely biologically determined.

The brain

The Brain

  • Simon LeVay discovered that there is a cluster of cells in the hypothalamus that is larger in heterosexual men than in heterosexual women or homosexual men.

Prenatal environment

Prenatal Environment

  • Current research seems to point to the hormonal levels in the prenatal environment.

  • We have created homosexual male fruit flies and lesbian sheep!!!

Achievement motivation what motivates us to work school job sports video games relationships etc

Achievement MotivationWhat motivates us to work?(School, job, sports, video games, relationships etc..)

Intrinsic Motivators

Extrinsic Motivators

Reward that we get for accomplishments from outside ourselves (grades or money or etc..)

Work great in the short run.

  • Rewards we get internally, such as enjoyment or satisfaction.

Achievement motivation

Achievement motivation

Where would one stand to practice if they had high achievement motivation?

  • Those with high achievement motivation will choose tasks that are moderately difficult. Not too hard because they want to achieve. Not too easy because they want to feel good about themselves.

Overjustification effect

Overjustification effect

Studies show that if you externally reward someone (excessively) for something they love doing, they will lose their intrinsic desire for doing it.

  • Alex Rodriguez earns 27.5 million dollars per year. Does he love the game??

Management theory management teaching styles relate closely to intrinsic extrinsic motivators

Management TheoryManagement/Teaching styles relate closely to Intrinsic/Extrinsic Motivators.

Theory X

Theory Y

Managers believe that employees are internally motivated to do good work and policies should encourage this internal motive.

Interested in Maslow’s higher needs.

  • Managers believes that employees will work only if rewarded with benefits or threatened with punishment.

  • Think employees are Extrinsically Motivated.

  • Only interested in Maslow’s lower needs.

When motives conflict

When Motives Conflict

  • Approach-approach conflict – when we have 2 desirable things to choose from. Both Beyonce and Tyra Banks want to date you.

Approach avoidance conflict

Approach –avoidance conflict

  • Both options have their benefits and drawbacks. Example, telling your wife that her hair looks bad. The good is she’ll fix it. The bad is she might be mad at you for a few hours.

Avoidance avoidance conflict

Avoidance-avoidance conflict

  • You must choose between 2 equally unattractive options.

Four theories of emotion

Four theories of emotion

James lange theory of emotion

James-Lange Theory of Emotion

  • Willam James and Carl Lange came up with the James-Lange Theory of Emotion.

  • Based on our autonomic nervous system

  • The body changes and our mind interprets those changes as emotion.

  • “I’m afraid because I run”

Motivation and emotion

  • Male participants were asked to meet an interviewer in the middle of one of two bridges. One was a safe-looking bridge and one looked more dangerous. An attractive female researcher interviewed the male passers-by in the middle of the two bridges. She gave them her telephone number in case they wanted to ask about the results. Men on the less safe-looking bridge were more aroused by the height of the bridge, and were likely to confuse their feelings for being 'lovestruck'. They were then more likely to call her back, looking for a date.

  • Support for James Lange????

Motivation and emotion

  • Giving the Finger, the Psychology and History Thereof By William Weir on February 13, 2009

  • For the study, 54 right-handed subjects read a story about a person whose behavior could be interpreted as either assertive or hostile. One group extended their forefinger while reading, another group extended their middle finger. The latter group tended to assert that person in the essay was hostile, rather than assertive.

  • Support for the James Lange theory??

Facial feedback hypothesis

Facial feedback hypothesis

The effects of facial expression

The Effects of Facial Expression

If facial expressions are manipulated, like furrowing

brows, people feel sad while looking at sad pictures.

Attaching two golf tees to the face and making their tips touch causes the brow to furrow.

Maybe ned was right sometimes we should force ourselves to smile

Maybe Ned was right. Sometimes we should force ourselves to smile.

Cannon bard theory of emotion

Cannon-Bard Theory of Emotion

  • Say James-Lange theory is full of crap.

  • The physiological change and cognitive awareness must occur simultaneously.

  • They believed it was the thalamus that helped this happen.

Think 2 cannons firing at the same time

Think – 2 cannons firing at the same time.

Physiologicalchange (heart rate, breathing)

Cognitive awareness

Two factor theory of emotion

Two-Factor Theory of Emotion

  • Stanley Schachter explains emotions more completely that the other two theories.

  • They happen at the same time but…

  • Emotion is processed in the autonomic nervous system AND the cerebral cortex (conscious thought)

  • Includes cognitive appraisal

Motivation and emotion

  • If you are in a falling vehicle heading toward the ground at 60 mph, your autonomic reaction would include heart racing and screaming. But if your cognitive appraisal says you are on a rollercoaster, then you have the emotion of “fun”

Everyone say it loud

Everyone say it loud

Schacter – Two Factor

Opponent process theory of emotion

Opponent Process Theory of Emotion

  • Have you ever felt crappy for a few days, then felt elated? This theory says feeling one way will lead you to feel the opposite.

  • How is this similar to the opponent process theory of color vision?



  • There are 2 stress hormones you need to know.

  • Cortisol and adrenaline

  • Cortisol does lead to weight gain.

Seyle s general adaptation syndrome

Seyle’s General Adaptation Syndrome

  • Describes our response to a stressful event.

  • Three stages

  • Alarm

  • Resistance

  • Exhaustion

Emotional expression

Emotional Expression

When culturally diverse people were shown six basic facial expressions, they did fairly well at recognizing them (Paul Ekman 1989).

Elkman & Matsumoto, Japanese and

Caucasian Facial Expression of Emotion

Motivation and emotion

Izard (1977) isolated 10 emotions. Most of

them are present in infancy, except for contempt,

shame, and guilt. Even blind children display these facial expressions.

Paul ekman basis for lie to me

Paul Ekman – basis for Lie to Me

  • Paul Ekman studied emotions and facial expressions and found there are universal facial expressions. Lying and disgust are the same in the USA and Japan.

  • However, the display rules are different for collectivist cultures than individualist cultures. Chinese are not encouraged to display anger like Americans are.

Cognition does not always precede emotion

Cognition Does Not Always Precede Emotion

When fearful eyes were subliminally presented to subjects, fMRI scans revealed higher levels of activity in the amygdala (Whalen et al. 2004).

Catharsis hypothesis

Catharsis Hypothesis

Venting anger through action or fantasy achieves an emotional release or “catharsis.”

Expressing anger breeds more anger, and through reinforcement it is habit-forming.

Cultural gender differences

Cultural & Gender Differences

  • Boys respond to anger by moving away from that situation, while girls talk to their friends or listen to music.

  • The expression of anger is more encouraged in individualistic cultures (USA) than in cultures that do promote group behavior (China, Japan)
