Q

What is the refutability criterion from Popper?

A

A scientific theory must state what observable data should be possible or impossible - argued that Freud/Adler’s theories are not REAL SCIENTIFIC THEORIES, but more border on the verge of pseudoscience
- must be able to be refuted

Q

What is the general consensus on the plaster vs. plasticity hypothesis?

A

Most personality psychologists agree that personality can change across childhood, but debate about adulthood

William James: “Plaster hypothesis - after 30, impossible to change personality, biological development becomes rigid and complete”

Plasticity hypothesis = personality is malleable and an change across the lifespan, because of new life experiences, psychotherapy, social influences

Q

What is absolute stability? / rank order consistency?

A

measures constancy of personality traits over time, focus on means within a sample of a specific trait, ie. extroversion
- using analysis of variance or T-Tests pair samples, want to be NON-SIGNIFICANT OVER TIME to demonstrate absolute continuity

Strong evidence for consistency = 0.6-0.9 correlations

Q

What is relative stability?

What type of measurement does it need?

A

people’s ranking compared to others changed, people scoring high on X compared to others is expected to stay at same level of X over time compared to other people

Needs the rank order to look the same, uses correlation coefficient,
needs a EXTREMELY HIGH CORRELATION COEFFICIENT across Time 1 and Time 2

Q

What are the findings for personality change? (how someone measures on a specific trait over time and compared to others)

A

Big changes in young adulthood and then slow down, emotional stability and conscientiousness tend to rise

Rank order / differential stability tends to also increase with age but is still never that close to a perfect correlation coefficient of 1

Lower correlation rank order stability between long assessment periods, eg. studying people from 3-60 years
No gender differences
No support for the plaster hypothesis
Plasticity hypothesis is corroborated

Q

What are the 4 types of data?

A

S Data - Self-reports, good insight for inner thoughts/feelings

I Data - Informants reports, family, friends, other lab participants, roommates, colleagues, good insight

L Data - Life Outcomes, hospital visits, tax record, marriages, university,

B Data - Behavioural Observations, audio recordings, lab, good for objectively viewing a person’s behaviour as they do not have a relationship to them/not biassed accounts of a person

Q

How do the different RMs differ in personality psych?

A
  1. Correlative research, individual differences are central, situation is peripheral
  2. Experimental research, treatment/situation is central, ignores individual differences
  3. Case studies, single individual is central

Q

Criterion validity?

A

does the measure predict an independent criterion in the same subject? You should get a correlation between the measure and the criterion

Q

Concurrent validity?

A

does your test correlate with a different test?

24
Q

Predictive validity?

A

does your test correlate and predict specific behaviours in the future?

25
MOST IMPORTANT: construct validity
does your measure appropriately measure a theoretical construct? Is it related to one construct that it should be related to?
26
What is the nomological network in validity?
a network of theoretical models including the relationship of your variables in measures to other variables in other related measures
27
Must a personality theory be supported by empirical evidence?
no
28
What is Discriminant/divergent validity?
your measure is NOT correlated with other UNRELATED measures, eg. a measure of narcissism is not correlated with life fulfilment
29
What is Split half reliability?
split one test into two halves, and then correlate participants scores of the two halves of the same test
30
Alternate form reliability?
= same participants are tested with one form of the same test and then another form of the same test
31
Inter rater reliability?
the extent to which different observers rate a person in the same/similar way
32
What is Heterotypic continuity in personality change?
reflects the consistency of fundamental differences in personality that change with age, eg. introverted child ≠ introverted adult but still have the trait of introversion
33
What are the three aspects of childhood temperament? (Vroman, Lo, & Durbin, 2014)
Positive emotionality Negative emotionality Effortful control These 3 types of temperament act as precursors via heterotypic continuity to traits in adulthood, eg. positive emotionality as precursor to extroversion
34
What are the 4 techniques to improve reliability?
1. care with research procedure 2. standardised research protocol 3. measure important not trivial variables 4. aggregation - averaging measures
35
What is the Spearman-Brown formula in psychometrics?
more error-filled measures are, the more measurements you need
36
What is construct validation?
strategy of establishing the validity of a measure by comparing it with a WIDE range of other measures
37
What is generalisability?
a broad combination of validity and reliability - what can the result generalise to?
38
What 4 things limit generalisability?
1. participant demographic 2. gender bias (difference in traits) 3. shows vs. no shows 4. ethnic and cultural lack of diversity
39
What is the third variable problem?
a potential third complication in between two variables
40
Can childhood personality ranks predict life outcomes?
YES 4- to 6-year-old children rated as more “inhibited” than most of their peers were slower to find a stable romantic partner and slower to find a first job 19 years later, compared to children rated as less inhibited
41
Are personality disorders stable and fixable?
relatively but less stable that those without personality disorders therapy not super effective
42
What 5 things keeps personality stable across lifespan?
1. heterotypic continuity 2. your physical and environmental features shape and maintain personality 3. birth order? not super well supported 4. early experiences of stress/bullying/exclusion lead to adverse traits and health outcomes (chronic biological inflammation) 5. person-environment transactions = seeking out environments that are compatible with personality traits
43
What types of parents produce more well-adjusted children?
1. educated parents produce more emotionally stable children, but not more contienscious
44
What is the cumulative continuity principle?
the idea that personality becomes more stable and unchanging over time, eg. most between 50-70 years
45
What are the 3 types of person-environment transcations?
1. Active person– environment transaction =Person seeks out compatible environments and avoids incompatible ones 2. Reactive person– environment transaction = Different people respond differently to the same situation 3. Evocative person– environment transaction = Aspect of an individual’s personality leads to behavior that changes the situations he or she experiences
46
Do traits change other traits?
YES
47
Why might personality be more stable over time?
the environment often becomes more stable along with other things like intelligence, eg. the "Flynn effect"
48
What does the end of history refer to?
feeling that we changed a lot in the past and probably won't as much in the future
49
What two things do we need to establish personality development?
showing rank order consistency and increase or decrease in a trait
50
cross sectional study?
study of people of different ages measured at the same time
51
what are cohort effects?
tendency for a finding to be limited to a cohort of people, particularly all living together in same location or time period, social and cultural environment shapes mass perspective
52
what does longitundinal data show? + maturity principle?
people often become more stable and less neurotic and better self-esteem people beocme more mature with age
53
Why does personality change?
1. aligns with cognitive changes 2. changes in life social roles require building new qualities and skills 3. the social clock pressure to do certain things by a certain age 4. developing a narrative identity (eg. McAdams approach), around late adolescence 5. changing goals
54
what are the aspects of narrative identity?
1. agency = getting through challenges and goals 2. redemption = bad things happening that produced good things
55
What traits do most people want to change?
1. neuroticism in many countries many people of all ages want to change to more socially desirable
56
what can produce personality changes?
yes - general intervention programs, targeted interventions, or behaviors and life experiences.
