Sept 5 Flashcards

1
Q

why talk about research methods?

A
  1. foster critical thinking & media literacy

headlines in media often sensationalize research findings, distorting nuanced insights and obscuring study limitations

many opinions about relationships online are presented as facts, but lack scientific backing

Q

confirmation bias

A

tendency to seek out, pay attention to, and believe evidence that supports our pre-existing beliefs

we aren’t objective observers of our relationship interactions - interpretations of events are biased by our expectations and emotions

Q

4 points on how our perspective is unique and limited

A
  1. experience has no control group (no way to limit confounders)
  2. your experience are just a small sample of all relationships
  3. often unaware of many forces on behaviours (ie. underestimate the power of the situation)
  4. too quick to see causal relationship where there may be none
    - just because two things co-occur, doesn’t mean one causes the other

Q

can love be studied? quote and perspectives

A

“no one - not even the National Science Foundation - can argue that falling in love is a science” - US Senator William Proxmire, 1975

studying love isn’t impossible, but it is challenging

Q

what is key to studying love?

A

how we OPERATIONALIZE these psychological constructs

need to carefully consider what we’re really measuring and what we think we’re measuring

Q

operationalizing our constructs

A

can’t measure psych constructs directly, only their operationalizations

ie. for attraction, could look at…
1. behavioural indicators (smiling, phone number exchange)
2. self-reported ratings of attraction
3. physiological measures (heart rate, brain activity)

Q

examples of questions on The Love Scale

A

rate on scale from 1-9 (true to not true)

if my partner were feeling badly, my first duty would be to cheer them up

I feel that I can confide in my partner about virtually everything

I find it easy to ignore my partner’s faults

I would do almost anything for my partner

When I am with my partner, I spend a good deal of time just looking at them

Q

comments on The Love Scale

A

takes love (abstract) and makes it quantifiable through specific statements

questions focus on care and affection aspects of love, but misses other things like commitment and passion

culturally biased - would this be appropriate all over the world?

but this scale is logical and makes sense

pros of self-report

A

cheap

easy to administer

25
social desirability bias
desire to be seen in a positive light relationship researchers deal with many sensitive topics ie. higher reported rates of infidelity in online surveys vs face to face interviews
26
people's definition of sex varies
asked people what constituted sex for them 13.9% = "you touch each other's genitals" 39.9% = "oral contact with other's genitals" 81% = "penile-anal intercourse" 95.5% = "penile-vaginal intercourse"
27
sentiment override
global beliefs about the partner/relationship may colour perception and memory of specific interactions ie. "how many times did your partner kiss you yesterday?" "I don't remember, but he loves me and we have a good relationship, so it must've been a lot"
28
behavioural observation
gather data about relationship events without having to ask people who are experiencing those events directly ie. how do people in happy and distressed relationships differ in the way they behave towards each other? train observers to WATCH & CODE recordings of participant behaviour
29
behavioural observation: can observe people...
1. in the lab 2. at home 3. anywhere! (speed dating events, airports)
30
behavioural observation: coders must agree about...
what constitutes incidents of a given behaviour category need INTER-RATER RELIABILITY
31
inter-rater reliability
extent to which coders agree on whether a specific behaviour has or hasn't occurred important in behavioural observation lots of behaviours require INTERPRETATION ie. lighthearted joke vs hostile sarcasm may be easier to agree on a SUPER CONCRETE behaviour, but lose the broader meaning of the behaviour ("can't see the forest through the trees") - ie. may agree that a SMILE has occurred, but each smile carries different meaning
32
coders require ________ _________ to ensure ________-_________ __________
extensive training inter-rater reliability
33
pros of behavioural observation
1. directly assess behaviours of interest 2. don't have to rely on faulty memories 3. avoid social desirability bias
34
cons of behavioural observation
1. expensive, time and labour intensive 2. reactivity: change in behaviour caused by knowledge one is being observed
35
reactivity
possible con of behavioural observation a change in behaviour caused by the knowledge one is being observed
36
indirect measures are designed to avoid...
1. reactivity 2. social desirability
37
reaction time is an example of what kind of measure?
indirect used to assess IMPLICIT ATTITUDES: the automatic tendency to associate a given stimulus with positive or negative feelings
38
the newlywed game study setup
bring in newlyweds assess their EXPLICIT and IMPLICIT attitudes towards partner sit in front of computer, briefly see picture of partner then see a cross then shown a word (either positive or negative) INSTRUCTIONS: indicate valence of word as quickly as possible
39
the newlywed game underlying premise
some concepts are more tightly linked in our minds on the basis of experience index of automatic attitudes = negative word RT - positive word RT higher score = more positive attitude positive feelings for partner facilitates identification of positive words
40
in the newlywed game, a higher score means...
more positive attitude towards your partner negative word RT - positive word RT because negative word RT should be longer than positive word RT
41
the newlywed game results
1. conscious/explicit attitudes NOT CORRELATED with implicit attitudes - suggests Ps aren't aware of implicit attitudes 2. IMPLICIT but not explicit attitudes associated with newlyweds' CHANGES IN SATISFACTION over time (4 years) 3. IMPLICIT attitudes predict NONVERBAL BEHAVIOUR in couple discussions - nonverbal behaviours linked to satisfaction with conversation and relationship satisfaction over following week - explicit attitudes didn't predict either verbal or nonverbal behaviour
42
newlyweds game: what did implicit attitudes predict?
1. associated with newlyweds' changes in satisfaction over time 2. predict nonverbal behaviour in couple discussion
43
newlyweds game: explicit attitudes didn't predict...
verbal behaviour nonverbal behaviour
44
pros of indirect measures
1. avoid social desirability & reactivity problems could be particularly useful for sensitive topics
45
cons of indirect measures
1. big gap between construct of interest and operationalization can we be sure that we're studying what we think we're studying
46
physiological responses
body's reaction to various experiences/stimuli 1. ANS activity (heart race, BP) 2. hormone changes (cortisol, sex hormones) 3. immune system changes 4. brain activity
47
challenges collecting & interpreting fMRI data
1. very confined & noisy environment - makes it hard to create powerful psychological experience for participants 2. don't see brain "activation" per se - infer activation by subtracting response on control from trial of interest - need to think carefully about task design
48
pros of physiological response measures
1. interesting in their own right (understanding link between relationships and health) 2. outside participants' control (not susceptible to social desirability bias, etc)
49
cons of physiological response measures
1. very expensive > leads to smaller size 2. ambiguity in interpretation 3. could be more invasive (depending on the measure)
50
archival data
draw on publicly available documents & data ie. marriage licenses, yearbooks, Facebook, personal ads data collected by someone else, often for an unrelated purpose
51
example of archival data
more positive facial expressions in yearbook photos predict likelihood of being happily married 30 years later
51
pros of archival data
1. typically economical 2. can examine historical trends
52
cons of archival data
limited by type and quality of og data also limited access to this data
52
measurement: takeaway
no single approach is perfect all have limitations ideally, want to adopt a multi-method approach - using combo of methods to triangulate on an answer
53
correlational design
examine NATURALLY OCCURRING associations between variables (the things we're measuring) ie. do people tend to be attracted to those more similar to themselves? strength of association captured by the CORRELATION COEFFICIENT (r) which ranges from -1 to +1 - sign tells us direction - magnitude tells us strength of association
54
pros of correlational design
sometimes the only option available some variables can't be manipulated by researchers ie. gender, culture, age, marriage status, chronic illness, having an affair
55
cons of correlational design
can't draw conclusions about CAUSATION (conclusion about cause and effect)
56
correlational design: does marriage cause happiness?
evidence to suggest that marriage & happiness are associated plausible that marriage may increase happiness BUT could also be true that happier people are more likely to get married OR optimistic people may be more likely to get married AND more likely to be happy
57
3 criteria must be met to conclude causation
1. two variables must be correlated 2. one variable must precede the other 3. there must be no reasonable alternative explanations for the pattern of correlation (no confounders)
58
cross sectional data
collected at single point in time
59
longitudinal data
collected from the same participants, about the same variables, on multiple occasions allows us to examine CHANGE OVER TIME ie. how does satisfaction change over course of relationship? ie. do communication patterns early in relationship predict whether the couple will stay together or break up later?
60
longitudinal research: 2 challenges & considerations
1. choosing the right interval (how long to follow them for, how frequently to assess them) 2. attrition: sample you start with may not be the sample you end with
61
longitudinal research: choosing the right interval
for certain questions, may need to follow couples for a long time (months, years, decades) sometimes, may be interested in more frequent assessments over shorter time period
62
daily diary study
type of longitudinal approach where Ps provide data everyday AT ABOUT THE SAME TIME
63
experience sampling
type of longitudinal approach where data is gathered THROUGHOUT THE DAY, thereby capturing behaviours, thoughts & feelings as they occur
64
attrition bias
participants may drop out those who drop out may SYSTEMATICALLY DIFFER from those remaining in the study
65
example of attrition bias
researchers have often observed u-shaped pattern of MARRIAGE SATISFACTION satisfaction is high, then drops slowly until low, then increases slowly until high again could be an ARTIFACT OF UNSATISFIED COUPLES DROPPING OUT OF STUDY
66
the U shaped pattern of marriage satisfaction could be...
an example of attrition bias an artifact of unsatisfied couples dropping out of the study
67
cons of longitudinal research
1. expensive in terms of time and labour 2. attrition bias 3. correlational: getting 1 step closer to making causal claims, but still not there
68
statistically controlling for alternative explanations
you measure an alternative variable that might explain your effect, and you INCLUDE IT in your analyses if your effect is just a proxy for something the control variable is doing, your EFFECT WOULD BE WIPED OUT ie. when children eat more ice cream, they're more likely to drown - have you tried controlling for whether it's summertime? - oh hey, the effect is gone. wild.
69
while statistically controlling for alternative variables is good...
1. this type of statistical control is still subject to limitations 2. can be hard to anticipate every relevant variable
70
experimental design
manipulate one variable to determine effect on another variable the ONLY design that (if properly executed) allows us to make causal claims independent and dependent variables
71
independent variable
the MANIPULATED variable in an experiment (possible cause)
72
dependent variable
the MEASURED variable in an experiment (possible effect)
73
importance of a good control
compare experimental group to control group to determine effect of experimental intervention want the control condition to match experimental condition AS CLOSELY AS POSSIBLE minus the key ingredient want to AVOID CONFOUNDS: alternate explanations for relationship between two variables
74
example of a control group to answer Q "are attractive people seen more positively?"
have participants rate target profiles on positive & negative personality traits manipulate attractiveness of photo: attractive or unattractive must make sure PHOTOS MATCH ON ALL OTHER FACTORS: - age - gender - race - quality/colour of photo
75
random assignment
every participant has equal chance of being assigned to experimental or control group with large enough sample, two groups should be similar on all these individual traits helps us rule out alternative explanations
76
why is random assignment important?
every participant brings unique set of perspectives, biases etc potential threat to internal validity
77
internal validity
can we rule out alternate explanations in the experiment? are we sure the effect is being caused by what we think it is?
78
what does internal validity rely on?
1. selection of appropriate controls 2. random assignment
79
pros of experiments
allow us to make causal claims caveat: as long as there are no threats to internal validity
80
cons of experiments
1. may have lower EXTERNAL VALIDITY 2. not always feasible
81
external validity
extent to which results obtained in a given context generalize to other contexts
82
often make universal claims about relationships, but...
don't study diverse samples ie. homosexual couples historically underrepresented in relationships research
83
WEIRD participants
Western Education Industrialized Rich Democratic because convenience samples are much easier and cheaper to get, they're used more frequently
84
representative sample
sample that resembles entire population we want to study on variables of interest ie. all nationalities, all SES backgrounds ie. national statistics agencies like StatsCanada very hard to get
85
even if we do a good job of reaching out to a representative sample...
the people who agree to participate may differ from those who don't
86
volunteer bias
people who agree to participate in a study may differ from those who don't
87
example of volunteer bias
mailed invitation to participate in longitudinal study to couples who'd obtained marriage license in LA county between 1993-1994 those who responded to invitation: 1. higher SES (more education, higher status job) 2. more likely to have cohabited prior to marriage
88
dyadic data: complicating the sample process
often want dyadic data to examine dyadic processes 1. means both partners need to agree to participate - not all couples do this, excludes lots of couples 2. are dyadic samples representative of the population or unique?
89
dyadic data: individuals whose partner agreed to participate with them reported...
1. greater relationship satisfaction 2. greater commitment 3. more secure attachment 4. less likelihood to break up over time
90
lecture takeaway
1. relationships researchers generally use a COMBO of convenience and more (though not totally) representative samples 2. having a non-representative sample doesn't make the study WRONG - it just limits the extent to which we can generalize our findings 3. some relationship phenomena more universal than others 4. NO ONE STUDY IS PERFECT
91
relationship science is an _______ process
incremental no one study is perfect
92
actor-partner interdependence model
allows us to examine how individual outcomes are affected by BOTH one's own characteristics (ACTOR EFFECT) and the partner's characteristics (PARTNER EFFECT) because we can recruit both members of couple, we can examine individuals' outcomes based on their own behaviour/thoughts/characteristics and also those of their partners
93
ethical issues in relationships research
1. asked to deeply think about & confide about issues of highly personal and sensitive nature 2. may experience negative effects like recognizing relationship problems for the first time 3. cost-benefit analysis - must be sure the benefits of the research are worth the costs 4. need to be sensitive in approaching participants, providing effective debriefing and counselling resources
