Test 2 Flashcards
Motivation
Inferred process within a person or animal that cause movement either toward a goal or away from an unpleasant situation
Theories of Motivation
An over-arching explanation for why people do the things that they do
Instincts
Automatic, involuntary, and unlearned behaviour patterns triggered by particular stimuli (e.g., a cat knows how to catch mice)
Fixed-action patterns
An instinctual behavioural sequence that’s relatively invariant within the species (E.g., Mother Turkey’s)
Releaser
the triggering stimulus – what cues the fixed action pattern (e.g., the “cheep, cheep” sound of baby turkeys)
Drives
A biological trigger that tells us we may be deprived of something and causes us to seek out what is needed, such as food or water
Primary Drives
innate like thirst, hunger, and sex
Secondary Drives
needs that have been conditioned to have
meaning (e.g, like money)
Incentives
the stimuli we seek that can satisfy drives such as food, water, social approval, companionship, and other needs
Drive Reduction Theories
- We feel unpleasant tension when we stray from homeostasis (physiological equilibrium)
- We become motivated (driven) to restore that physiological equilibrium (satisfy the need)
Homeostasis
The body’s physiological processes that allow it to maintain consistent internal states in response to the outer environment
Drive Reduction Theory
- we have physical needs
- unmet needs create drive
- that drive pushes us to reduce the need
Arousal Theory
The body’s physiological processes that allow it to maintain consistent internal states in response to the outer environment
Yerkes-Dodson Law
Performance increases with arousal only up to a point, beyond which performance decreases
What happens when we preform simple or well-learned tasks?
Performance improves as arousal increases
What happens when we preform complex, unfamiliar, or difficult tasks?
relationship between arousal and performance reverses after a point, and performance declines as arousal increases
Abraham Maslow
Believed that individuals posses a constantly growing inner drive that has great potential (created the hierarchy of needs - purple pyramid)
Self-Determination Theory
proposes that people have three primary motives:
* Autonomy
* Relatedness
* Competence
Autonomy
To cause outcomes in your own life—act consistently with your self-concept
Relatedness
To feel connected with others who are important to you—care for others and experience caring
Competence
To feel mastery over your life - to perform tasks at a satisfying level
What is the key distinction with self-determination theory?
extrinsic and intrinsic motivation
Extrinsic Motivation
a person tends to do a task or activity mainly because doing so will yield some kind of reward or benefit upon completion (also known as performance motivation - gaining rewards) e.g., paycheck
Intrisnic motivation
characterized by doing something purely because of enjoyment or fun (also known as mastery motivation - overcoming challenges while enjoying it)
Over-justification effect
The addition of external motivation can undermine internal motivation
Self-efficacy
Confidence that one can plan and execute a course of action
Approach Goals
are enjoyable and pleasant incentives that we are drawn toward, such as praise or financial reward
Avoidance Goals
are unpleasant outcomes such as shame, embarrassment, or emotional pain, which we try to avoid
Three Motivational Conflicts
- Approach-approach conflicts * Conflicts that occur when you are equally attracted to two or more possible goals
- Avoidance-avoidance conflicts * Conflicts that require you to choose the lesser of two evils because you dislike both alternatives
- Approach-avoidance conflicts * Conflicts that occur when a single activity or goal has both a positive and a negative aspect
Hunger
The need to consume enough nutrients so that you have enough energy to function. it is our major drive
Ventromedial Hypothalamus
stimulation reduces eating (“off” switch);
destruction causes overeating
Lateral hypothalamus
stimulation increases eating (“on” switch);
destruction reduces eating to starvation level
What happens when the ventromedial hypothalamus no longer functions?
Hunger regulation no longer functions properly
Felling full is in the ________ not the _________
brain; stomach
The biology of weight
Research does not support the idea that people who are overweight are emotionally disturbed. Heaviness is not always caused by overeating
Set Point
Genetically influenced weight range for an individual. Varies 10% either direction
Basal metabolic rate
the rate at which the body burns calories for energy
Why does the ob gene cause obesity in some individuals?
Ob gene causes fat cells to secrete the protein leptin
What receptors urge us to eat?
receptors in the nose and mouth
What receptors urge us to stop eating?
receptors in the gut
Ghrelin
Makes you hungry
Leptin
Turns off appetite
What does sugar activate?
pleasure-inducing dopamine pathway
Prevalence of obesity in Canada
Approximately 26% of women and 35% of men
Social Facilitation
Eating more when we’re around other people –it’s a social activity
Impression Management
eating in order to fit in or not be embarrassed (E.g., eating less –ordering a salad on the first date)
Minimal eating norm
good manners—at least in some social and cultural settings—is to eat small amounts to avoid seeming rude
Modeling
eating whatever others eat
“Mindless Eating”
unintentionally influenced by container size or colour
Wansink & Kim “Mindless Eating” study
- gave away fresh popcorn for free
- moviegoers ate 45.3% more when it was given to them in a large container
- gave away free 14 day-old popcorn
even though it was disliked, they still ate 33.6% more popcorn - when asked 77% percent said size didn’t affect how much they ate
Van Ittersum & Wansink Dish Size & consumption study
Increasing the size of the dishes increases consumption by 18–25% for meals and 30–45% for snack foods
Wansink, Painter, & North Attention and Eating Study
Bottomless bowl of soup study:
* Individuals stopped eating after
consuming, on average, over 70%
more than those participants who
knowingly refilled their bowls
Master’s and Johnson’s four stages of sexual response:
- Excitement
- Plateau
- Orgasm
- Resolution
Sex differences: compared to women, men…
- Think about sex more often
- Initiate sex more often in relationships
- Desire sex more often in relationships
- Masturbate more
- Report fewer problems with low sexual desire
- More often pay money or offer gifts for sex
- More often watch (and pay for) pornography
- Have orgasms more reliably and easily than
women
Clark & Hatfield Study
- “go out with me tonight?”
- “come over to my apartment tonight?”
- “go to bed with me tonight?”
* women would more likely say yes to question 1, whereas men would most likely say yes to question 3 (but still 1+2 but not as high)
Problem with Clark & Hatfield’s Paradigm
- Riskier for women to agree
- Men and women are perceived
differently when they propose casual
sex (Conley, 2010) - Female proposers are perceived as
more intelligent, successful, and
sexually skilled than male proposers
Arousal in measured in what two ways?
- self-report
- Physical
Better sex results in…
- Men less likely to leave
- More satisfied wives two years later
- Men’s satisfaction fluctuated with frequency of sex
Better relationships result in…
- Higher sex satisfaction 18 months later, if relationship satisfaction and effective communication are high
- Greater sex satisfaction 1 year later if wife has open communication and high perceptions of stability
- More sexual satisfaction, following a 5-session marital communication intervention
People can engage in sex for approach/promotion reasons:
- To feel good
- To share intimacy/be closer with our partner
- To have fun
People can engage in sex for avoidance/prevention reasons:
- To stop our partner from leaving
- To stop our partner from being upset
- To stop feeling guilty
Human are innately social beings:
- The needs to belong affects thoughts, emotions, and behaviours
- Feelings of love activate the brain reward and safety systems
- Social isolation increase the risk from mental decline and poor health
Affiliation need
the need to build relationships and to feel a part of a group
The standard of a beautiful body has changed:
In the 1900-1950, larger and heavier women were considered more attractive than now. Now, thinner women are considered more attractive. However, waist-to-hip ratio has not changed
Waist-to-hip-ratio and fertility
Married women with higher ratio reported more difficulty becoming pregnant.
Low waist-to-hip ratio is associated with absence of major diseases
Matching Phenomenon
Men and women of similar attractiveness are
drawn to one another
Why does the Matching phenomenon work?
Attractive people and unattractive people have different standards. Highly attractive people have high standard. Less attractive people have lower standards.
Good News about Beauty and Matching
Regardless of the level of physical attractiveness, people generally rate their spouses as attractive
Speed-dating results
Participants self-reported traditional sex differences in hypothetical mate preferences
* Men – physical attractiveness
* Women – earning prospects
However, these did not pan out in actual ratings of partners
What can we conclude about Matching Hypothesis & Beauty/Status Trade?
People don’t seem to know why they fall for who they
Online dating services:
Customers typically end up going out with fewer
than 1% of the people whose profiles they study online
Speed-dating events
The average participant makes a match with at
least 1 in 10 of the people they meet; some studies have found the average is 2 or 3 out of 10
Why is there a difference in online dating services?
When you have all criteria to consider, and
so many people to choose from, you start striving for perfection
Why is there a difference in speed-dating?
People realize that there aren’t an infinite number of possibilities…If they want to get anything out of the evening, they have to settle for less than perfection
Stereotype about dating
- Men are indiscriminate pursuers who will go for anyone with a heartbeat
- Women are selectors—the romantic gatekeepers who thrive on saying “no”
Attractiveness and Time of Day
Men and women approached at 9, 10:30 or 12 PM to rate attractiveness of people in the bar at the time. Called “The Closing Time Effect”
Attractiveness and Time of Month
- Women who were not on hormonal birth control rated different faces at different times of the month
- During ovulation, greater preference for more masculine faces; at other times, more feminine faces
Bottom line of Attraction
Many factors play a role in what we find attractive, and we don’t always know why we are attracted to some people
Passionate Love
Aroused state of intense positive absorption in another, usually at the beginning of a love relationship
Compassionate Love
The feelings of intimacy and affection we feel toward someone with whom our lives are deeply intertwined
Intimacy
feelings of being close and bonded
Passion
arousal and sexual attraction
Commitment
short-term commitment to love your partner, long-term to maintain that love and stay with them
What are the three components of Emotion?
- A subjective thought and/or experience
- accompanying patterns of neural activity and physical arousal
- an observable behavioural expression
Emotion
a state of arousal involving facial and bodily changes, brain activation, cognitive appraisals, subjective feelings, and tendencies toward action.
Physiology of emotions
Physiological Changes in the Brain and Body
Routes of emotion: fast route
skips the visual cortex and goes strait to the amygdala for an instant emotional reaction
Amygdala
A brain structure involved in the arousal and regulation of emotion and the initial emotional response to sensory information “threat detector”
Assesses threat
Becomes activated during the perception of arousing or aversive/fear-inducing stimuli (e.g., Loud noises, Noxious odours, Bad tastes etc.)
Routes of emotion: slow pathway
Sensory input is routed to the cortex for analysis and then transmission to the amygdala
Prefrontal cortex
the most forward part of the frontal lobes of the brain
Emotional regulation
modifying and controlling what we feel, associated with emotional experience
