Core components of personality
traits, states, acts
Traits
characters, values, temperament; generally consistent, stable, and have internal cues
States
feelings, experiences, thoughts in reaction to external situations; private, short-term
Acts
behaviors, activities, habits; observable, have internal/intentional causes
Related components to personality
physical appearance, social effects/evaluations (effect you have on others), talents/skills
Personality
characteristics of a person that describe and account for consistent patterns of feeling, thinking, and behaving
Freud’s philosophical view of the person
people are driven by sex & aggression, anxiety & defense mechanisms
Rogers’ philosophical view of the person
people are driven by self-actualization, congruence between self + experience, incongruence & defensive mechanisms (denial + distortion)
Comprehensiveness
theory fully explains and accounts for a wide variety of aspects in a phenomena
Parsimony
theory explains the phenomena in the simplest way so that it is understandable and can be generalized to many situations
5 areas personality theories should address
structure, process, growth & development, psychopathology, change
Structure
how is a personality is organized and how are its basic, enduring parts are connected and interact with each other?
Process
what motivates someone to do something?
Growth & development
how does personality develop?
Psychopathology
how do people cope with stress/anxiety?
Change
can personality change over time?
Bandwidth & example
theory explains a wide range of phenomena (ex. A radio has a bunch of channels)
Fidelity & example
theory explains the specifics of the phenomena (ex. When you try to listen to a channel within a radio, it is clear and easy to hear)
Bandwidth-fidelity trade-off
sometimes, you can’t have both strong bandwidth and fidelity in a theory, so theorists will have to choose which one they want their theory to be stronger in
What does the Prof John and traffic cop scenario show?
the traffic cop’s speed monitor is reliable because it shows Prof John speeding at 90 mph every time he speeds BUT it may not be a valid measurement for safety because Prof John claims that he is safe whilst driving 90 mph
How is the amniotic fluid test a fallible measurement?
you can’t actually measure exactly how much fluid is in the amniotic sac (unreliable); if you measure it multiple times, the amount will vary
Principle of aggregation & example
get a bunch of items/observations and average them to get a single aggregate/overall score (ex. Instead of taking an exam with 1 question, where the only possible scores are 0% or 100%, it’s better to take an exam with 20 questions to get an accurate sense of how much a student has learned)
Example of the principle of aggregation
chicken oviduct story; single observations do not always capture the same results (unreliable), so you need to use 100 test tubes and average the results to account for those that are overestimations and underestimations
Reliability
how well the measurements/observations are stable across time, dependable, and replicable
Retest reliability & example
across time; how well the results of the same test given to the same people at different time points correlate with each other (ex. A student should get the same score on the same exam now and 2 weeks later)
Parallel test/alternate form reliability & example
across tests; how well one measure of the construct correlates to a similar measure of the same construct (ex. A student should get the same score on form A as form B)
Split-half reliability/internal consistency & example
across items; how well the items within a measure correlate with each other (ex. A student should get the same score on the first 10 questions of the exam and on the last 10 questions of the exam)
Interjudge agreement reliability & example
across observers; how well the ratings of different observers correlate with each other (ex. A student should get the same score when graded by different GSI’s)
How can we make sure our theory is valid?
use LOTS of different data sources/methods
What does LOTS stand for?
Life data, Observer data, Test data, Self data
Life data
life history & records (ex. School, criminal, employment)
Pros and Cons of Life data
pros: objective, you can measure ‘real world’ outcomes cons: no info on thoughts, feelings and why
Observer data
rating made by others (teachers, parents, peers, trained observers) that are data coded by researchers (ex. Admin in the back of the class)
Pros and Cons of Observer data
pros: provides multiple perspectives, others may know you better than yourself, can be less biased than self data cons: observer bias, issues can arise with interjudge reliability, situation & being observed may influence behavior
Test data
experiments, standardized/timed tests (ex. SAT/ACT, marshmallow experiment)
Pros and Cons of Test data
pros: objective, can control/manipulate situation, measure causal relationship cons: articifical settings can mess with validity and generalizability, demands characteristics that wouldn’t happen naturally, experimenter expectancy effects, some phenomena can’t be studied in the lab
Self data
questionnaires, interviews (ex. Myers-Briggs Type Indicator)
Pros and Cons of Self data
pros: easy to get large samples & measure many variables at once, some phenomena can only be measured through Self data cons: can’t claim casual relationships, people may not answer truthfully because of social desirability, people tend to agree with questions/statements
Validity
how well our measure actually measures what we want it to measure
Content validity
how well a measure comprehensively represents all facets of the construct
Criterion validity
how well a measure correlates with other measures on the same construct & how well it predicts future outcomes
Convergent/discriminant validity
how well a measure correlates with related measures & doesn’t correlate with unrelated measures
Pros and Cons of case studies & clinical research
pros: more natural settings, can study the full complexity of an individual cons: unsystematic, subjective, no causal relationship
Pros and Cons of lab studies & experimental research
pros: manipulation of variables, objective, causal relationships cons: some things can’t be studied in a lab, artificial settings pose issues for external validity/generalization, demand characteristics & experimenter expectancy effects
Pros and Cons of questionnaires & correlational research
pros: can study a wide variety of variables and their relationships, easily get large samples cons: no causal relationships, self-reports have issues with validity + reliability, no in-depth studies of individuals
Nomothetic approach
use fixed measures that are applied and computed the same way for everyone to figure out common laws and principles that are generalizable for all individuals of a population
Pros and Cons of nomothetic approaches
pros: simple, easy to administer + analyze, objective cons: items may be irrelevant, features of personality may not be included
Idiographic approach
use flexible measures that are tailored to an individual to get a full picture of the unique individual
Pros and Cons of idiographic approaches
pros: get more relevant info to the individual cons: may need guided instructions for administering, more difficult and time-consuming to analyze
Longitudinal study
test the same individuals at multiple time points to see how their results have changed over time
4 problems with the ACL
(1) a lot of adjectives are applicable to most people (most people would say they’re ‘friendly’) so it’s not really meaningful (2) some people check a bunch of boxes while some people check few boxes (3) people go through it mindlessly without even thinking about it (4) it’s unclear what it means when someone doesn’t check a box (NA or doesn’t understand)
Correlation
linear association between two variables from -1.00 to +1.00
Explain the meaning of a .40 correlation
strong correlation, usually seen in medical and social sciences; changes odds from 50/50 to 70/30 (40% increase)
Explain the meaning of a .30 correlation
typical correlation in research; changes odds from 50/50 to 65/35 (30% increase)
Explain the meaning of a .08 correlation
small correlation, but can be meaningful; aspirin has a .08 correlation for avoiding heart attack; changes odds from 50/50 to 54/46 (8% increase in not getting a heart attack)
Can you infer causation from correlation? & example
aw hell no! There may be confounding/3rd variables that may explain the correlation (ex. Height & intelligence are correlated; good nutriention can lead to taller height and better brain development)
4 reasons for studying Freud
(1) he discovered new techniques (free association, dream interpretation, transference, projective tests) which informed subsequent research (2) he had rich observations from in-depth case studies (3) his theory led to more psychological theories as others built upon his work or made theories that went against his work ( 4) he addressed topics central to the human experience that were not covered on other theories (ex. Dreams, sexual desires, internal mental conflicts, infant psychological life)
Psychic determinism
theorizes that all mental processes are not spontaneous but are determined by the unconscious or preexisting mental complexes
Big 2 instincts and their evolutionary basis
sex & aggression; selfish gene (we wanna pass down our genes)
Why do humans have sexual & aggressive drives?
sex-linked with physical pleasure; aggression linked with survival
Conscious
thoughts and perceptions that are you actively thinking about
Pre-conscious
memories, stored knowledge that you can pull from when needed
Unconscious
fears, violence, unacceptable desires/impulses that you cannot access without the help of the trained professional
Dichotic listening task & example
listen to right ear (conscious listening) while a story plays in the left ear (unconscious listening); story on your left influences your perception of of the story on the right (ex. River bank vs. money bank)
What does the dichotic listening task prove?
System 1 & 2 communicate with each other; System 1 sends unconscious messages from the left ear to the to System 2 while System 2 was consciously interpreting the right ear
Cocktail party phenomenon
our unconscious monitors the environment and pings the conscious when important info is found (ex. Name, potential dangers, sex)
Verbal slips & example
slip of the tongue that is motivated by and reveals information from our unconscious; Freud believed this occurs when our unconscious interferes with our conscious thoughts (ex. Tennis match “nice to ‘beat’ you!”)
Automatic vigilance example
Stroop color-interference paradigm: difficulty naming the color of a word when it doesn’t match the spelling of a word
Id
animalistic impulses, source of drive energy (sex, aggression, life, death), seeks to relieve immediate tension through the pleasure principle, satisfaction through action/imagination
Ego
satisfies the id with reality and the demands of the superego in mind like a balancing act (dynamic equilibrium), follow the reality principle
Superego
morals, ideals, rewards good behavior with pride/self-love and punishes bad behavior with guilt/inferiority, overly harsh & unrealistic, can be forgiving because of circumstances
Pleasure principle
pursue pleasure, avoid pain
Reality principle
delay gratification and uses reality to get the maximum pleasure and minimum pain
Primary process thinking & example
reflective habit, unconscious, illogical, can’t tell the difference between fantasy and reality, child-like, emotional, needs immediate gratification, used by the id to release tension and fulfill the pleasure principle (ex. Seeing an attractive person at the grocery store and wanting to have sex with them)
Secondary process thinking & example
takes effort, conscious, logical, tests reality, develops over time, used by ego to fulfill the reality principle (ex. Seeing an attractive person at the grocery store and wanting to ask them on a date)
System 1
(1) evolutionary older, limbic system (2) fast but inaccurate (3) effortless (4) automatic; falls under unconscious primary process thinking
System 2
(1) evolutionary newer, brain cortex (2) slow but detailed (3) takes effort and uses limited capacity (4) can be controlled and therefore changed; falls under conscious secondary process thinking
Freud’s psychosexual vs. Erikson psychosocial stages of development
Oral stage
ages 0-1, fixation in mouth area, sucking instinct; same time as Trust vs Mistrust
Anal stage
ages 2-3; fixation on anus, conflict between retention and expulsion, learning self-control; same time as Autonomy vs Shame
Phallic stage
ages 4-5, fixated on genitals, Oedipus/Electra complex; same time as Initiative vs Guilt
Latent stage
6-adolescence, sexual/aggressive tendencies are dormant/hidden/repressed, focus on asexual forces (school, friendships, etc.); same time as Industry vs Inferiority
Genital stage
adolescence, onset of puberty, Freud's final stage where people reach ‘maturity’,; same time as Ego Identity vs Role Confusion
Trust vs Mistrust
ages 0-1, learn if primary caregivers are trustworthy, responsive parenting; same time as Oral stage
Autonomy vs Shame
ages 2-3, learning independence, patient parenting vs restrictive parenting; same time as Anal stage
Initiative vs Guilt
ages 4-5, taking satisfaction in accomplishments, actions begin to have purpose, developing sense of right and wrong; same time as Phallic stage
Industry vs Inferiority
6-adolescence, developing competence, learning skills to be a successful member of society; same time as Latent stage
Ego Identity vs Role Confusion
adolescence, developing an identity; same time as Genital stage
Intimacy vs Isolation
early adulthood, finding a partner
Generativity vs. Stagnation
middle adulthood, giving back to the next generation
Ego Integrity vs. Despair
late adulthood, looking back to see if life was fulfilling
Why do we like Erikson’s psychosocial stages better than Freud’s psychosexual stages?
included both biological + social forces, addressed entire life cycle
Marcia’s identity statuses
Achievement
commitment with exploration
In moratorium
no commitment with exploration
Foreclosure
commitment without exploration
Diffusion
no commitment and no exploration
Harlow’s monkeys
monkeys chose cloth mother over metal milk mother, suggesting the need for physical contact and closeness; evidence against Freud’s oral stage of development
Fixation
when a person becomes preoccupied with themes related to a certain erogenous zone; no evidence for this (ex. People who weren’t breastfed don’t all end up as smokers)
Regression
returning to an earlier stage based on a fixation; usually happens when people are stressed/frustrated/anxious
