Trait / Disposition
A building block of personality, traits are universal dimensions with individual differences.
Two Perspectives on Traits
- Traits as Internal Causal Properties (Internal traits cause people to act in particular ways)
- Traits as Purely Descriptive Summaries (Traits are purely descriptive summaries of attributes of persons, they make no assumptions about internality or causality)
The Act Frequency Formulation of Traits
Looks at implications of the descriptive summary trait perspective. Traits are viewed as categories of acts.
The Three Elements of The
Act Frequency Research Program
Act nomination, prototypicality judgement, and the recording of act performance
Act Frequency Research Program (AFRP)
Act Nomination
First step of AFRP. A procedure designed to identify which acts belong in which trait categories. Essentially, involves slotting behaviours/outward manifestations of traits into specific categories.
Eg. Categorizing someone striking up conversation with a stranger as an act of friendliness/extraversion
Act Frequency Research Program (AFRP)
Prototypicality Judgement
Second step of AFRP. Identifying which acts are most central to (prototypical of) each trait, as in, what acts are the best examples of a trait.
Eg. Impusively spending a large sum of money may be ranked as more impulsive than making a snap decision to go out with friends
Act Frequency Research Program (AFRP)
Recording of Act Performance
Third step of AFRP. Securing information on the performance of individuals in their daily lives.
List the three approaches to identifying the ‘most important’ traits
Lexical approach, statistical approach, theoretical approach
Lexical Approach to IDing Personality Traits
In which traits listed and defined in the dictionary form the basis of describing differences among people. Uses the lexical hypothesis that all important individual differences have become encoded within the natural language.
The Lexical Approach’s Two Criteria For Identifying Important Traits
Synonym Frequency: The more synonyms there are to describe an attribute, the more important that attribute is.
Cross-Cultural Universality: The more important a difference/attribute is, the more languages that will have a term for it.
Statistical Approach to IDing Personality Traits
Make sure to be able to define covariance
In which researchers use factor analysis to identify major personality traits.
The statistical approach starts with a large, diverse pool of personality items, and asks individuals to self-rate based on those items.
Then, researchers apply statistical methods in order to sort items by covariance.
Factor analysis is the primary statistical method: Helps us determine groups of items that “covary” or “go together.”
From the textbook: The goal is to identify dimensions/“coordinates” on the personality map.
Factor Analysis
Factor Analysis: Identifies groups of items that covary (go together) with each other, but not with other groups of items.
F.A. reveals clusters that have common properties, and can be useful in reducing large swathes of personality traits into a smaller and more useful set of underlying factors.
Factor Loadings
Indexes of how much of the variation in an item is “explained” by a factor (basically correlations).
Theoretical Approach to IDing Personality Traits
Starts with a theory, and the theory determines which variables or traits are important to study.
If the theory is very good, it will save us a lot of time spent looking at unhelpful variables.
But, depending on how much the theory contains gaps or biases, there can be many flaws/omissions/distortions as well.
Taxonomy
A classification scheme.
Eysenck’s Hierarchical Model of Personality
Make sure to know the three broad traits
A model of personality, based on traits Eysenck believed were highly heritable/had a likely psychophysiological foundation.
Three traits:
E - Extraversion (introversion)
N - Neuroticism (emotional stability)
P - Psychoticism
His model was hierarchical, with narrow traits falling under broad traits. Narrow traits consist of habitual actions (patterns), which consist of specific actions.
Eysenck
Extraversion Narrow Traits + Psychophysiology
Traits: Sociable, active, lively, dominant, etc.
Psychophysiology: Extraverts experience more positive affect. Introverts have higher cortical and nervous system arousal to moderate-to-high levels of stimulation.
Neuroticism Narrow Traits + Psychophysiology (Eysenck)
Traits: Anxiety, depression, guilt, low-self-esteem, emotional
Psychophysiology: Associated with greater reactivity (physiological and psychological) to stress and negative stimuli.
High N Individuals: Stay angry longer, less likely to forgive, more vigilant to threats, etc.
Psychoticism Narrow Traits + Psychophysiology
Narrow Traits: Aggressive, cold, egocentric, antisocial (socially disruptive)… creative
Psychophysiology: Associated with higher testosterone, and lower monoamine oxidase
Controversial: Including creativity as a narrow trait of P
A lot of psychoticism narrow traits are spread out through The Big 5 traits
Hierarchical Structure of Eysenck’s System
- Super trait at the top of the hierarchy
- Narrower traits at the second level
- Habitual acts at the third level (eg. sociable at second level, socializing frequently at the third level)
-At the very lowest (4th) level are specific acts (eg. I raised my hand in class) - If enough specific acts are repeated frequently, they become habitual acts (go up to the third level)
The Two Key Biological Underpinnings of Eysenck’s Personality System
Heritability: Any personality dimension in Eysenck’s system must have reasonably high heritability
Identifiable physiological substrate: For any personality dimension in Eysenck’s system, one must be able to identify properties in the brain and CNS that can presumably be linked to/be a causal property of this dimension.
Physiological Substrate: Eg. Extraversion associated with CNS arousal/reactivity
Gray’s Reinforcement Sensitivity Theory
List the two hypothesized biological systems in the brain
Also be sure to know the three systems of Gray’s theory
Jeffery Gray (1972, 1990)
Model of personality with two hypothesized biological systems in the brain:
1. Responsive to reward (those more sensitive to this were said to be impulsive)
2. Responsive to punishment (those more sensitive to this were said to be anxious)
Three systems (detailed in other flashcards): Behavioural activation system (BAS), Fight-Flight-Freeze System (FFFS), Behavioural Inhibition System (BIS)
Gray’s Reinforcement Sensitivity Theory
Behavioural Activation System (BAS)
Brain system responsive to reward, motivates approach behaviours: novelty-seeking, extraversion, etc.
Higher BAS = Higher positive emotion, novelty-seeking, extraversion, etc.
Not sure if this is testable, but some brain regions relevant to this system include: thalamus, cerebral cortex, striatum
Gray’s Reinforcement Sensitivity Theory
Fight–Flight–Freeze System (FFFS)
Brain system responsive to negative stimuli, mediates the fear response
Higher FFFS = motivates avoidance behaviours, fear-proneness, phobias
Not sure if this is testable, but some brain regions relevant to this system include: amygdala, anterior cingulate, hypothalamus
