Exam 2 Flashcards
Motivation
An inferred process within a person or animal that causes movement either towards 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 stimulation
i.e. cats know how to catch a mouse
Fixed-action patterns
an instinctual behavioural sequence that’s relatively invariant within the species
i.e. mother turkeys and how they protect their young
Releaser
is the triggering stimulus–what cues the fixed action pattern
i.e. the “cheap, cheap” sound of babies 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
are innate like thirst, hunger, and sex
Secondary drives
are needs that have been conditioned to have meaning like money
Incentives
are the stimuli we seek that can satisfy drives such as food, water, social approval, companionship and other needs
Theories of Motivation–Drive reduction theories
we feel unpleasant tension when we stray from homeostasis
we become motivated (driven) to restore that physiological equilibrium (satisfy the need)
Arousal Theory
humans are motivated to engage in behaviours that either increase or decrease arousal levels
Yerkes-Dodson law
Performance increases with arousal only up to a point, beyond which performance decrease
relationship can be characterized as a bell shaped curve where arousal can increase performance only up to a point
when levels of stress or arousal become too high, performance decreases
Different tasks require different levels of arousal for optimal performance. How does this work for simple and complex tasks?
simple or well-learned tasks: performance improves as arousal increases
complex, unfamiliar or difficult tasks: the relationship between arousal and performance reverses after a point, and performance declines as arousal increases
What is the Hierarchy of Needs? and who created it?
Abraham Maslow created the Hierarchy of Needs in the 1940’s.
He believed that individuals possess a constantly growing inner drive that has great potential.
What are the levels of the Hierarchy of Needs from bottom to top?
Self-actualization needs
Aesthetic needs
Cognitive needs
Esteem needs
Belongingness needs
Safety needs
Physiological needs
Self-Determination theory
proposes that people have 3 primary motives:
1. Autonomy
2. Relatedness
3. 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
Extrinsic Motivation
performance motivation
a person tends to do a task or activity mainly because doing so will yield some kind of reward or benefit upon completion.
i.e. a paycheck
Intrinsic Motivation
mastery motivation
is characterized by doing something purely because of enjoyment or fun
i.e. if you have an awesome workplace where you enjoy what you do
Over Justification Effect
The addition of external motivation can undermine internal motivation
i.e. students who previously enjoyed solving puzzles showed less intrinsic motivation after being paid
Self efficacy
confidence that one can plan and execute a course of action
Approach goals
enjoyable and pleasant incentives that we are drawn toward, such as praise or financial reward
i.e.getting married in order to live a shared life
Avoidance goals
unpleasant outcomes such as shame, embarrassment, or emotional pain, which we try to avoid
i.e. getting married to avoid being alone
What are the 3 motivational conflicts?
- Approach-approach conflicts–when you are equally attracted to 2 or more possible goals
- Avoidance-avoidance conflicts–require you to choose the lesser of 2 evils because you dislike both alternatives
- Approach-avoidance conflicts–when a single activity or goal has both positive and a negative aspect
Hunger
the need to consume enough nutrients so that you have enough energy to function
what does the ventromedial hypothalamus do?
stimulation to this area reduces eating; destruction to it causes overeating (“off” switch)
What does the lateral hypothalamus do?
stimulation to this area increases eating; destruction reduces eating to a level of starvation (“on” switch)
The biology of weight
research does not support the idea that people that people who are overweight are emotionally disturbed
heaviness is not always caused by overeating
biological mechanisms regulate your body weight and are influenced by genetics
Set point
genetically influenced weight range for an individual
when your body falls below your “set point” weight, increased hunger and a lower metabolic rate may combine to restore weight lost (and vice versa)
how are genes are involved in some types of obesity?
mutations in the ob gene may cause obesity in some individuals
ob gene causes fat cells to secrete a protein called leptin that acts on the hypothalamus and helps to regulate appetite
normals levels of leptin cause us to eat enough for maintenance
low levels cause us to overeat
what do the receptors in the nose and mouth do?
urge us to eat
what do the receptors in the gut do?
urge us to stop eating
What does the hormone ghrelin do?
it makes you hungry
What does leptin do?
it turns off your appetite
what does sugar do?
activates pleasure-inducing dopamine pathway
What is the prevalence of obesity in Canada?
approximately 26% of women and 35% of men
It has been increasing over the years and is not solely from genetics
What does “kummerspeck” mean?
“grief bacon”
sometimes people eat when they don’t physiologically need to–there are other things that influence whether we eat, beyond just hunger
Social facilitation
eating more when we’re around other people–it’s a social acivity
impression management
eating in order to fit in or not be embarrassed
i.e. eating less on a 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” study 1
they gave away free popcorn in either medium or large containers
moviegoers who were given fresh popcorn ate 45.3% more popcorn when it was given to them in large containers
they were influenced by the container size
“Mindless Eating” study 2
in another study some participants were given stale, 14 day old popcorn
even though people disliked it, they still ate 33.6% more popcorn when eating from a large container than from a medium container
when asked if they thought they ate more because of the size of the container: 77% of those given the large tubs said they would have eaten the same amount if given a medium container
Implications
what is an appropriate “serving size”?
Bottomless bowl of soup study (2005)
individuals stopped eating after consuming, on average, over 70% more than those participants who knowingly refilled their bowls
shows how people’s consumption is determined, in part, by external cues such as the bowl
Master’s and Johnson’s four stages of the sexual response
- Excitement
- Plateau
- Orgasm
- Resolution
Compared to women, men…
- think about sex more
- initiate sex more often in relationships
- desire sex more in relationships
- masturbate more
- report fewer problems with low sex drive
- more often pay money or offer gifts for sex
- more often watch porn
- have orgasms more reliably and easily than women
Clark and Hatfield (1989) study about sex on campus
“I’ve been noticing you around campus. I find you to be very attractive. Would you…”
“go out with me tonight?”
“come over to my apartment tonight?”
“go to bed with me tonight?”
-men and women both said about 50-55% for the date
-70% of men and only 5% of women agreed to go to the apartment
-75% of men and 0% of women agreed to go to bed
What does better sex result 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 5-session marital communication intervention
People can engage in sex for approach reasons like:
-to feel good
- to share intimacy/be closer with our partner
- to have fun
People can engage in sex for avoidance reasons like:
- to stop our partner from leaving
- to stop our partner from being upset
- To stop feeling guilty
Affiliation need
the need to build relationships and to feel a part of the group
Humans are innately social beings–3 points
-the need to belong affects thoughts, emotions and behaviors
-feelings of love activate the brain’s reward and safety systems
-social isolation increases the risk for mental decline and poor health
The standard of beauty has changed. How?
In 1900-1950, larger and heavier women were considered more attractive than now
Study on waist-to-hip ratio and fertility (1990)
-married women with higher ratio reported more difficulty getting pregnant
Matching Phenomenon
men and women of similar attractiveness are drawn to one another
(couples, friends, and spouses tend to share the same values, attitudes, and beliefs)
Opposites do not attract
attractive people and unattractive people have different standards
Good News about matching
regardless of the level of physical attractiveness, people generally rate their spouses as attractive
What did they find out about attractiveness?
attractiveness is NOT universal, beauty is all determined individually
Eastwick & Finkel (2008) study about matching
-people were asked to rate the importance of attractiveness and earning prospects (self reported)
-the self reported found that men value physical attractiveness and women value earning prospect
-then went on little 4 minute “speed dates”
-then rated the attractiveness and earning prospects
-these did not pan out in actual rating of partners
Online Dating services
customers typically end up going out with feweer than 1% of the peoples whose profiles they study online
when you have all these criteria to consider, and so many people to choose from, you start striving for perfection
Speed-Dating event
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
people realize 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”
What is the bottom line about attraction?
many factors play a role in what we find attractive, and we don’t always know why we are attracted to some people
often beauty is truly in the eye of the beholder
Passionate Love
Aroused state of intense positive absorption in another, usually at the beginning of a live relationship
Companionate Love
The feelings of intimacy and affection we feel toward someone with whine our lives are deeply intertwined
Triangular Theory of Love (Sternberg)
suggests to at love has 3 basic ingredients:
-intimacy
-passion
-commitment
Intimacy (Triangular Theory)
feelings of being close and bonded
Passion (Triangular Theory)
arousal and sexual attraction
Commitment (Triangular Theory)
short term commitment to love your partner, long term to maintain that love and stay with them
Emotions have the following 3 components:
- a subjective thought and/or experience with
- accompanying patterns of neural activity and physical arousal and
- an observable behavioural expression
Emotion
is a state of arousal involving facial and bodily changes, brain activation, cognitive appraisals, subjective feelings, and tendencies toward action
The fast route
skips the visual cortex and goes straight to the amygdala for an instant emotional reaction
stimulates activity in sensory areas
Amygdala
a brain structure involved in the arousal and regulation of emotion and the initial emotional response to sensory information
Assesses Threat
becomes activated during the perception of arousing or aversive/fear-inducing stimuli
i.e. loud noises, odours, bad tastes
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
associated with emotional experience and emotional regulation: modifying and controlling what we feel
Left Prefrontal cortex
more tuned to approach emotions
i.e. happiness, enthusiasm
if damaged results in loss of joy
Right Prefrontal cortex
more tuned to unpleasant emotions
involved in withdrawal and escape from unpleasant and frightful stimuli
i.e. disgust
Autonomic nervous system
a control system that acts largely unconsciously and regulates bodily functions such as the heart rate, digestion
Schachter & Singer: Two Factor Theory
The experience of emotion depends on two factors:
-Physiological arousal and cognitive interpretation
Emotion:
-physical response
-cognitive interpretation
-conscious experience
Schacter and Singer’s classic study
all participants received an epinephrine injection (adrenaline)
told that it either causes arousal or has no effect
participants were then put in a waiting room with someone else who either acted.. Angry or Euphoric/Goofy
results:
if participants expected the shot would increase arousal, then it did not have an effect on their emotions
However, if participants did not expect the shot to affect arousal, participants interpreted it based on the situation
Dutton & Aron-arousal river study
Capilano river:
high scary suspension bridge
low stable suspension bridge
Approached by an attractive female research assistant and then she gave them her number to “call her for the results”
Results:
the males that met the woman on the suspension bridge found her more attractive and were more likely to call her (12.5% vs. 50%)
the feelings of arousal that the male hikers experienced on the bridge were misinterpreted as attraction (Misinterpretation attraction)
what is the bottom line about interpretation
emotion is determined, in part, by our appraisal/interpretation of the situation
the same principle occurs for evaluations of stressful events (an event is only stressful for people if they interpret it that way)
Body language
nonverbal signals of movement, posture, gesture and gaze
Emotional dialects
variations across cultures in how common emotions are expressed
Display rules
social and cultural rules that regulate when, how and where a person may express emotions (or must suppress)
Health psychology
is the branch of psychology concerned with the promotion of health and the prevention of illness
Placebo effect
the percepton that one has received an intervention improves one’s symptoms
Nocebo effect
An intervention that one has received an intervention decreases symptoms or increases side effects
