Unit VIII - Motivation, Emotion, and Stress Flashcards
What is motivation?
a need or desire that ENERGIZES and directs BEHAVIOR
How is motivation pushed or pulled from us?
Our motivations arise from the INTERPLAY between NATURE (the bodily “push”) and NURTURE (the “pulls” from our personal experiences, thoughts, and culture).
Our MOTIVES drive our behavior.
From which perspectives have psychologists viewed motivation?
Instinct theory
Drive reduction theory
Arousal theory
Hierarchy of needs
What is an instinct?
a COMPLEX behavior that is rigidly PATTERNED throughout a species and is UNLEARNED
What are examples of instincts?
IMPRINTING in birds
RETURN of salmon to BIRTHPLACE
Infants’ innate reflexes to root for a NIPPLE and SUCK
What is instinct theory?
Instinct theory views our INSTINCTS as the source of our MOTIVATIONS.
Instinct theory states that the MOTIVATION to SURVIVE is the most IMPORTANT motivation and the innate behaviors that aid survival drive our motivations
How do physiological needs create a drive?
PHYSIOLOGICAL NEEDS (such as for food or
water) create an AROUSED, MOTIVATED state—
a drive (such as hunger or thirst)—that pushes
us to behave in a way that reduces the need and
returns the body to HOMEOSTASIS
What is homeostasis?
a tendency to maintain a BALANCED or CONSTANT
internal state; the REGULATION of any aspect of body CHEMISTRY, such as blood glucose, around a
PARTICULAR level
What is drive-reduction theory?
the idea that a PHYSIOLOGICAL NEED creates
an AROUSED state (a drive) that motivates an organism to satisfy the need and restore the body to HOMEOSTASIS, or balance
How does drive reduction theory explain how we regulate our body temperature?
Similar to THERMOSTAT
FEEDBACK LOOPS- sensors detect temperature, if too cold, blood vessels constrict to conserve warmth
DRIVEN to put on more clothes/ seek warmer environment
How is behavior pulled by incentives?
we also are pulled by incentives— positive or negative environmental stimuli that lure or repel us.
Can one behavior be both pushed and pulled?
When there is BOTH a biological need and an incentive, we feel STRONGLY driven.
The food-deprived person who smells pizza baking may feel a strong hunger drive, and the baking pizza may become a compelling incentive.
Can curiosity be a motive?
Curiosity drives monkeys to try to figure out how to unlock a latch that opens nothing.
What other behaviors might curiosity explain?
Curiosity DRIVES newly mobile infants to investigate every ACCESSIBLE corner of the house, and it drove students, in one experiment, to CLICK on pens to see whether they did or didn’t deliver an electric shock.
How do humans seek optimal levels of arousal?
Having ALL our biological needs SATISFIED, we feel DRIVEN to experience STIMULATION
lack simulation- BORED/ try to INCREASE arousal
Too much stimulation- try to DECREASE arousal
What is the Yerkes-Dodson law?
MODERATE arousal leads to OPTIMAL performance
What is optimal arousal?
BETWEEN bored LOW arousal and anxious hyperarousal lies a FLOURISHING life.
What is Abraham’s Maslow’s theory of motivation?
Abraham Maslow
theorized that human needs are HIERARCHICAL….some have PRIORITY over others
What is a hierarchy of needs?
PHYSIOLOGICAL needs that must FIRST be satisfied before HIGHER level safety needs and then PSYCHOLOGICAL needs are ADDRESSED.
What is self-transcendence?
people strive for MEANING, PURPOSE, and COMMUNION in a way that is TRANSPERSONAL—beyond the self.
Is the order of Maslow’s hierarchy fixed?
The order of Maslow’s hierarchy is NOT UNIVERSALLY fixed.
Starvation - political statement
Self-esteem matters most in individualist nations, whose citizens tend to focus more on personal achievements than on family and community identity.
What is the order of Maslow’s hierarchy of needs?
Physiological Safety Belongingness & love Esteem Self-actualization Self-transcendence
Research on hunger
Ancel Keys perform SEMI-STARVATION experiment, halved food intake- men became listless & apathetic- body weight stabilized about 25% less than starting
What were the psychological effects of being semi-starved?
men- food OBSESSED
TALKED food, DAYDREAMED food
Lost interest in SEX & SOCIAL activities
WWII survivor Louis Zamperini - drifted with two other members in Pacific Ocean for 47 days- to pass time, they …
recited recipes
recalled mothers’ home cooking
How is hunger related to stomach contractions?
When hungry and felt hunger pang, stomach contractions occur
Can hunger exist without stomach contractions?
Without stomach contractions. hunger still persist
Rat and humans without stomach still eat/ can be hungry
What is glucose?
the form of SUGAR
that circulates in the blood and
provides the MAJOR SOURCE OF
ENERGY for body tissues
How does blood glucose impact hunger?
Glucose level in blood DROPS will trigger HUNGER
APPETITE hormones released from HC, stomach, intestines, pancreas, and liver ALL signal brain to motivate.not motivate eating
What role does the hypothalamus play in hunger?
HC performs body MAINTENANCE
Blood vessels supply HC, enabling it to RESPOND to current blood chemistry/ neural information
How does the arcuate nucleus impact hunger?
A SMALL structure in the BASE of the hypothalamus, the arcuate nucleus plays a KEY role in the REGULATION of appetite and body weight.
What are the two portions of the hypothalamus that control appetite?
Lateral hypothalamus
ventromedial hypothalamus
lateral hypothalamus (LH)
Stimulation of this structure in the hypothalamus STIMULATES hunger
without this, hunger signals are inhibited
ventromedial hypothalamus (VMH)
Stimulation of this structure in the hypothalamus INHIBITS hunger.
without this, full signals are inhbitited
What research has been conducted?
When the neural center which secretes APPETITE-SUPPRESSING hormones is electrically STIMULATED, animals will
STOP eating.
DESTROY area causes obesity and uncontrollable eating
What are five appetite hormones?
Insulin leptin PYY ghrelin orexin
insulin
decreases appetite
hormone secreted by PANCREAS; controls blood GLUCOSE
leptin
decreases appetite
protein hormone secreted by FAT CELLS; when abundant, causes brain to increase metabolism and decrease hunger
PYY
decreases appetite
DIGESTIVE TRACT hormone; sends “I’m not hungry”
signals to the brain
ghrelin
increases appetite
hormone secreted by empty STOMACH;
sends “I’m hungry” signals to the brain
orexin
increases appetite
a hunger-triggering hormone produced by the HYPOTHAMALUS
What is the set point?
the POINT (weight) at which your “WEIGHT THERMOSTAT” may be SET (fixed)
What happens wen body fall below set weight?
Increased hunger
Lowered metabolic rate
What oppositions are there to the idea of set point?
Some researchers DOUBT that our bodies have a preset tendency to maintain OPTIMUM weight
Slow, sustained changes in body weight- alter set point
Given unlimited access to a wide variety of tasty foods, people and other animals tend to _______ and ____ ______
overeat
gain weight
Instead of set point, some researchers prefer term ///
settling point
Settlign point
level at which a person’s weight settles in response to caloric intake and expenditure.
What is basal metabolic rate?
the RESTING rate of energy EXPENDITURE for maintaining BASIC body functions.
How was basal metabolic rate impacted in Keys’ semi-starvation experiment?
By end of 6 months, men stabilized at 3/4 normal weight by REDUCING energy expenditure due to drop in basal metabolic rate
If amnesia patients with no memories of events occurring a few minutes ago, were offered lunch, they would readily eat it. This suggests that part of knowing when to eat is…
memory of our last meal
How does culture influence hunger?
Japanese people enjoy natto, fermented soybean dish- super smelly
Asians repulsed be stinky cheese
Peruvians likes roasted guinea pig
Alaskans eat whale blubber
Is there a relationship between geography and food spices?
Countries with hot climates, in which food historically spoiled more quickly, feature recipes with more
bacteria-inhibiting spices.
How do situations control our eating behavior?
Some situations arouse our appetite more than others.
In one experiment, watching an intense action movie (rather than a non-arousing interview)
doubled snacking.
Do we eat more when we are around others?
Most people do.
After parties ppl have overeaten- presence of others tends to amplify our natural behavior tendencies
Does serving size matter?
Researchers studied the effects of portion size by offering people varieties of free snacks.
The consistent result:
offered a supersized portion, people put away more calories.
What does the research on serving size show?
People eat more with bigger plate
Children eat more with adult-sized plates
Bigger bowl- more ice cream
Have cooking shows influenced healthy eating?
Today dozens of cooking shows are broadcast to
millions of U.S. viewers daily. Yet FEWER Americans than ever are home cooking
their own, more healthful meals.
Does food variety stimulate eating?
Yes- people eat more at buffets
Ancestors-variety was healthy- wide range of vitamins
How can we use behavior science to improve nutrition?
Obama, in 2015, used executive order to use behavioral science to better serve Americans
What has worked?
One research team quadrupled carrots
taken by offering schoolchildren carrots before they picked up other foods in a lunch line.
A new school lunch tray puts fruits and veggies up front, and spreads the main dish out in a shallow
compartment to make it look bigger.

What is body mass index (BMI)?
measurement of your body FAT based on your WEIGHT in relation to your HEIGHT.
Why was storing fat adaptive?
Carried ancestors through famine
Impoverished places find heavier bodies attractive
How do set point and metabolism contribute to obesity?
Fat requires less food intake to maintain that to gain
Weight below set point-> brain triggers hunger and metabolism
Body perceives STARVATION-> adapts by burning fewer calories
How does sleep loss make us more vulnerable to obesity?
Sleep deprivation increases the release of GHRELIN which stimulates the appetite and decreases the release of LEPTIN which reports body fat to the brain.
Is sex a need?
Sex is not like hunger, because it is not an actual NEED. Yet sex MOTIVATES.
A small number of human are ASEXUAL and have no sexual attraction to others.
How do sex hormones influence human development?
Prenatal period- sex hormones direct sex
Puberty- sex hormones ushers into adolescence

testosterone
estrogen
testosterone
Present in both sex
Additional in male influences development in womb/ during puberty
estrogen
Contribute to female sex characteristics
Secreted in higher amount in females
Peak during OVULATION
How do hormones influence sexuality?
females- sexually receptive during peak estrogen
testosterone drops in females- waning sexual interest
Males with low testosterone levels- increase testosterone- more energy/sexual desires
How can hormonal surges impact sexual desire?
The surge of hormones that occurs during puberty TRIGGERS the DEVELOPMENT of sex characteristics and sexual interest.
Castration of prepubertal boys results in ….
sex characteristics and sexual desire
do not develop normally
How can hormonal decline impact sexual desire?
Sex remains a part of life, but as hormone levels decline, sexual fantasies and intercourse
decline as well.
How can hormonal shifts impact sexual desire?
Surgery/drugs may cause hormonal shifts
Castration-> sex drive fell
Drugs reducing testosterone levels-> lost sexual urge
Because of our highly developed _____, sex hormones have ____ control over our behavior than they do over other animals’ behavior.
brain
less
What about hormone replacement?
We might compare human sex hormones, especially testosterone, to the fuel in a car. Without fuel, a car will not run. But if the fuel level is MINIMALLY ADEQUATE, adding more WON’T CHANGE how the car runs.
What is the sexual response cycle?
the
FOUR stages of sexual responding
described by William Masters and
Virginia Johnson in 1966
What are the 4 phases?
excitment
plateau
orgasm
resolution
excitement
The genital areas become ENGORGED with blood, causing a woman’s clitoris and a man’s penis to SWELL. A woman’s vagina EXPANDS and secretes LUBRICANT; her breasts and nipples may ENLARGE.
plateau
Breathing, pulse, and blood pressure rates continue to INCREASE. The penis becomes fully engorged and some fluid may appear at its tip.
A woman’s vaginal secretion continues to INCREASE.
orgasm
Muscle contractions appear all over the body and are accompanied by further increases in breathing, pulse, and blood pressure rates. The pleasurable feeling of sexual release is much the same for both sexes.
resolution
The body gradually returns to its unaroused state as the genital blood vessels
release their accumulated blood. This happens relatively quickly if orgasm has occurred,
relatively slowly otherwise.
What is the refractory period?
period in which another orgasm is not possible
Men’s refractory periods are ______ than women’s,
longer
What are biological influences on sexuality?

Religious & personal values
Cultural expectations
Media
How do external stimuli influence sexual arousal?
People become aroused when interacting with erotic material
Repeated exposure results in habituation
How important are psychological factors?
Compared with our motivation for eating, our sexual motivation
is LESS influenced by biological factors.
Psychological and social-cultural
factors play a BIGGER role.
Can exposure to sexually explicit material have adverse effects on women?
Yes
Depictions of sexual coercing/ enjoyment increased false belief that women wants to be overpowered/ hurting women/ committing rape
Can exposure to sexually explicit material have adverse effects on relationships?
Yes
Causes people to judge others as less attractive
Relationships to be less satisfying
Can exposure to sexually explicit material have adverse effects on men?
yes

Does imagination play a role in sexual arousal?
95% of people have sex fantasies
Men tend to have more frequent physical and less romantic fantasies
some men prefer faster paced sexual content
How does commitment enhance contentment?
In one national study that followed participants to age 30, later first sex predicted GREATER satisfaction
in one’s marriage or partnership.
How does building a relationship enhance sexual satisfaction?
Those whose relationship first developed to a deep commitment, such as marriage, not only reported greater relationship satisfaction and stability but also
better sex.

belonging
How do we create ‘us’?
Bonds at school, band, sports
Parting -> DISTRESS - promise to call, write
Sharp circle around us- attachment to “us” and hostilities to “they”
What does the research on isolation show?
Risk for mental decline
Older adults-> more doctor visits/ lonely- greater risk for dementia
Bereaved-> empty life- overeating
What is ostracism?
deliberate social
exclusion of individuals or groups
Ostracism example Henry Flipper
ostracized by white cadets at US Military Academy
became first black West Point grad
Experiment-> some students told they would end up alone or didn’t belong in a group
Those students became more likely to engage in self-defeating behaviors/ act in aggressive ways against those who has excluded them
Checking your phone is a way to …
feel connected to others even if there has been no text messages
How have we changed how we connect?
Social networking sites
Typical US teen with phone sends 30 texts a day
68% uses Internet
How does social networking influence us?
By connecting LIKE-MINDED people, the Internet serves as a social AMPLIFIER.
In times of social crisis or personal stress, it provides INFORMATION and SUPPORTIVE connections.
It enables people to SHARE their experiences and compare their lives with others, though it can be depressing when one garners few likes or has lots of bragging friends.

Lower grades
Increased anxiety & depression
What is achievement motivation?
a desire for SIGNIFICANT
accomplishment, for MASTERY of
skills or ideas, for CONTROL, and for
attaining a HIGH standard
