What is Personality Psych? Flashcards
what is personality?
- Set of psychological traits and mechanisms within individual
- Organized (disorganization occurs in those with disorders)
- Relatively enduring
- Influences interactions with and adaptations to environment (physical, intrapsychic, and social)
what is NOT personality?
- Attitudes, morals, values, and beliefs (because these are highly malleable and change over time)
- Abilities (cognitive or otherwise)
- Physical characteristics
- Social categories (ex. “Bully”)
- But personality can interact with all of the above
what is temperament?
- Innate qualities and characteristics a person is born with
- Typically used to refer to emotionality (ex. Calm, anxious, nervous)
- Interchangeable with nature, character, disposition, makeup
levels of analysis
- human nature
- individual and group differences
- individual uniqueness
levels of analysis: human nature
- How we are like ALL others
- Traits/mechanisms typical of our species; possessed by nearly everyone
- Ex. Pro-social tendencies
levels of analysis: individual and group differences
- How we are like SOME others
- Individual differences: ways in which each person is like some other people (ex. Introverts, sensation-seekers)
- Group differences: ways people of one group differ from another group (ex. Cultural differences, age differences)
- Important not to make conclusions about individual differences based on group differences
levels of analysis: individual uniqueness
- How we are like NO others
- Everyone has unique qualities not shared by any other person in the world
- This uniqueness is the sum of traits and mechanisms -> their combinations and interactions (rather than one sole trait)
early attempts to understand personality
- Astrology
- Humoral theory (surplus/imbalance of bodily fluids affecting personality)
- Physiognomy (personality assessment based on shape of body, esp. face)
- Phrenology (personality assessment based on morphology of skull)
2 means of personality assessment today
- descriptive research: describing personality (ex. what is a person’s level of extroversion?)
- explanatory research: used to discover relationships between personality factors and other phenomena (ex. is extroversion related to empathy?)
descriptive research relies on what?
- Self-reports (S-Data)
- Observer reports (O-Data)
- Test data (T-data)
- Life history/life outcome (L-data)
what is the goal of descriptive research?
- triangulation!
- process of evaluating a phenomenon using multiple sources/types of data
- ex. do self-report findings on shyness replicate with observer report data?
- low-moderate correspondence across all types of data
types of explanatory research (and their major limitation)
- correlational designs
- experimental designs
- meta-analyses (important for achieving scientific consensus)
- case studies
- limitation: typically WEIRD research (70% from the USA)
S-Data
self-reports (ie. surveys, interviews, experience sampling)
O-Data
info provided by someone else (ie. psychologists, teachers, friends & family)
naturalistic vs. artificial observation
- naturalistic: observing in natural environment (ex. home, school)
- artificial: observing in lab setting
T-Data
- info from standardized tests (not just written, can also include standardized lab tests)
- includes physiological data, projective techniques
physiological data
- measuring physiological responses (ie. heart rate, blood pressure, etc.) to indicate aspects of personality
- ex. using eye-blink test to measure fear response in people with high levels of psychopathy
- ex. using fmri to measure levels of brain activity
projective techniques
- person is given standard ambiguous stimulus and asked to report what they see
- ex. Rorschach test
L-Data
- info gathered from events, activities, and publicly-available outcomes in person’s life (ex. Amount of times one’s been married, speeding tickets, internet visiting history)
- can often be predicted by S-data and O-data
3 standards used to evaluate personality measures
- reliability: ability to repeatedly accurately measure the trait of interest (consistency)
- validity: extent to which a test measures what it claims to measure (accuracy)
- generalizability: the degree to which a measure retains its validity across various contexts (ie. across people, across conditions)
