Personality

The study of individual differences for identifying ways in which people are similar and different


-explains how thry become that way -similar attributes= similar behavior -different attributes = different behavior

Psychological qualities of personality

Qualities that contribute (influence) to an individuals enduring (consistent) and distinctive (differentiate individuals) patterns of feeling, thinking and behaving

What are personality models two functions

Description


-describe the ways people are similar and different from one another (trait terms)



Prediction


-set of ideas for predicting future behavior

Barnum effect

Cogntive bias that occurs when individuals believe that generic personality descriptions and statements apply to themselves


-is so general that it can be applied to everyone

Traits

Typical ways of thinking, feeling and acting in various situations at different times

Traits are

Used to describe personality



Influenced by the interaction of physiology and environment



Relatively stable



Expressed in diverse ways

Structural components

Represent stable, enduring aspects of personality


-stable over time


-building blocks or units of analysis of personality theories


- represented by traits

Genetics

Study of how genes and environment affect personality and behavior


-specific inherited personality characteristics and potentialities (expressed in person depending on environment)

How are people's genetic determinants of personality reflected in an individuals

Temperament


Emotions


Genes and molecule biology

Temperament

Biologically based emotional and behavioral tendencies present in infancy and early childhood that form building blocks of adult personality

Emotions

Seven basic emotions have large genetic components

Genes and molecular biology

Specific parts of the gene that are responsive to nervous system development that effect behavior

Neuroscience

Study of how brain and CNS affect personality by studying


-bodily responses (heart rate)


-brain structure and activity (EEG)


-biochemical activity (neurotransmitters)

Process components (3 processes on before slide)

Are the dynamic or motivational components of personality that change over relatively brief or extended periods of time


-explain rapid dynamic flow of motivation emotion and action


-drive behavior

3 categories of process components (1)

Pleasure or hedonic motives


-people are motivated by pursuit of pleasure or the avoidance of pain


Ex. Psychodynamic thoeires

3 categories of process components (2)

Growth or self actualization motives


-peoples attempts to grow a number of ways and realize their potential even at the costs of increased tension


Ex. Humanistic theories

3 categories of process components (3)

Cogntive motives


-people are motivated to understand, predict and explain their own ans other people's behavior


Ex. cognitive models of behavior

Growth and development

Explains personality development across life span

Two explanatory challenges of personality development

Normative development


-describing and explaining developmental patterns experienced by most people (differences in mean level)



Individual differences


-understand developmental factors contributing to Individual differences (rank level differences)

Early personality development ideas focused on nature nurture debate but recent work looks at

- genes and environment interaction and the weight attached to these factors


-developmental factors influencing personality


-epigenetics


Epigenetics

Phenotypic changes in terms of gene expression in the absence of changes in DNA sequence


-environmental influences induce changes in stable epigenetic states that regulate gene expression and complex neural functions

Epigentic mechanisms

Are molecular events that govern the way the environment regulates the genomes of organisms


-leads to individual differences in appearance, physiology, cognition and behavior

Example study of Epigentic

WW 2 the siege of leningrad and Dutch Hunger Winter


-famine during Prenatal period lead to smaller babies who had increased insulin resistance (impared glucose tolerance)


-showed reduced DNA methylation (CH3)

Two kinds of environmental factors

Macro


Micro

Macro factors

Through enculturation and socialization processes people learn the behavior, rituals and beliefs of their class, group, sub group or family


-these behaviors, rituals and beliefs reflect the religious, philosophical and political beliefs of their class

Micro factors?

How do family relationships parenting styles and peer groups influence personality

Development and family relations

Parental influences on personality development work through



Modeling effects


-parental behavior creates reactions to ans responses from children



Level of maternal sensitivity



Dimensions that underlie parenting style


-acceptance and rejection


-warm loving and cold rejecting

Examples of non shared environmental influences

Modeling effects


Level and type of attachment


Level of maternal sensitivity


Parenting style

Development and peer influence

Contribute to non shared environmental influence by socializing peer group members outside the home


-peers generate normative expectations about how age based peers are supposed to behave (social influence effects)

Evolutionary forces

Development of behavior and traits that are adaptive to the environment and that facilitate survival


-how personality attributes may have evolved through natural selection

What does heyes (2010) propose (read slides)

That cognitive mechanics like imitation, mentalizing, empathy and language are not inherit to humans.


Are the result of cultural factors that shape the development of such processes


-tools make cognitive structures more accessible than others

Self and identity

Personal sense of who one is


-self concept


-self esteem


-social identity

Why is the concept of self important

Explains why our personality and others appear intergrated and whole instead of a fragmented sense of self



Phenomenological self



Explains why we think we know about who we are (self schema)

Phenomenological self

Our subjective sense of self


A sense of who we are as invidividuals

Intrapsychic foundations

Examination of conscious and unconscious thoughts and feelings


-psychoanalytic theory (frued)


-psychodynamic thoeies (noe freudians)


-uncounscious motivations


-defence mechanisms


-attachments

Two interrelated questions raised by the psychodynamic perspective

1) to what degree do unconscious compared to conscious processes influence thoughts, behaviors and emotions



2) why is that an important question


-inflcue of past on present and future behavior


-adresses how the past, present and future behaviors are studied


-how much weight should be given to such events that happen in the past

Why are these two questions important

Answers to both questions influence


-how is personality studied


-what aspects of personality functions are to be studied


-what interpretations are to be made for conscious behaviors (signs vs samples)


-what casual factors are unconscious behaviors

Signs vee samples

?

Inttistically motivated

Feelings of free choice and adjustment


Personal competence


Connections to other


Conscious and unconscious environmental responses

Self determination theory

Draws on humanistic principles that emphasize the desire to grow, develop and bring about postive self change

What are the 3 basic needs that bring postive self change

Autonomy


-must be free to make choices



Competence


-need to feel skilled, achieve mastery at skill level appropriate tasks


-feel effective and able to expand abilities



Relatedness


-meaningful relationships with others, reciprocal relatedness, feeling inter connected



(When these 3 r ment people are intristically motivated (self determined) and happy to participate in activities)

Cogntive foundations

Difference in how we process information about the causes of events and outcome in their lives.


These differences influence


-future expectations


-emotions accociated with anticipated outcomes


-loss of control, learned helplessness, optimism- pessimism

What are the 4 structural concepts in social cogntive theory

1) personal goals (goal expectations)


2) competencies and skills (self efficacy expectations)


3) expectancies and beliefs (outcome expectations)


4) behavioral standards (self directed criteria)

LOTS

Life data (99%)


-info from a person life history or life record (school grades)



Observer data (89%)


-info from knowledgeable observers (parents)



Test data (86%)


-info from experimental studies and standardized tests



Self report data (100%)


-info from the person (questionnaires)

Advantages of self reports

Convenient


Easy to obtain


Easy to score


Reliability and validity can be established

Limitations of self reports

People may be unaware of their psychological characteristics



People are motivated to present themselves in a postive light

Triangulation

Combination of data to create a comprehensive understanding and confidence in research findings


Data overlapped


-LOTS

Nomothetic method (fixed)

Same measures are given to all participants, responses scored in thr same way


-means law


-ranks and comparisons

Nomothetic method advantages

Removes research from the realm of philosophical speculation



Provided empirical evidence



Construct validity and reliability of measures needs to be demonstrated

Idiographic method (flexible)

Some traits are unique to an individual


-Reflects clinical approach


-root word meaning idiosyncratic


-cant be compared


-tait in two people can differ in connotation or importance


-allows people to describe themselves in own words

Correlation coefficient

Measures the relationship between two variables


-postive (both up)


- negative (one up other down)



Magnitude


-small (0 to 3, 0 to -3)


-medium (3 to 5, -3 to -5)


-large (5 to 9, - 5 to -9)

Variable relations

First causes second



Second causes first



Other variable cause both variables

Typologies

Personality is repsented by distinct and discontinuous categories


-gender

4 typologies proposed by hippocrates and Galen

Choleric (irritable)


Melancholic (depressed)


Sanguine (optimistic)


Phlegmatic (calm)


-come for the 4 basic elements

What are Sheldon's 3 body types

1) endomotphs


-rounded/ soft


-viscerotonic (relaxed, comfortable, extovered)



2) mesomorphs


-square/ muscular


-somotonic (active, dynamic, assertive, aggressive)



3) ectomorphs


-thin/ fine boned


-cerebrotonic (introverted, thoughtful, sensitive)

Quantitative vs qualitative

The difference between people is quantitative rather than qualitative.


-people differ as to how much of a trait is incorporated in their personality

Personality hierarchy

Traits can be organized into hierarchy that ranges from specific behaviors at the lowest level to global and abstract trait structures at the highest level

The trait concept

Traits refer to consistent pattering of distinctive behaviors, feelings and thoughts


-consistency (traits describe regularity in behavior)


-distinctiveness (individual difference)

What are the 3 functions of all trait theories

1) description ☆


-traits summarize what the person is typically like (trait taxonomy: list of trait terms)



2) prediction ☆


-about everyday behaviors and the strength of a trait



3) explanation


-why is this happening


-traits are inhereited biological factors which determins individual differences

Where do trait taxonomies come from

Theoretical


-begjns with observations and hunches of what traits exist and go together



Lexical


-explores a particular language and identifies triat terms



Measurement


-use measurement techniques to discover personality dimensions

Example of theoretical (Eysenck personality theory)

Started with theories of hippocrates and Galen and Carl Jung



Proposed two super traits that combines these personalities


-introversion and extroversion


-emotionality and stability

Example of theoretical model (interpersonal circle)

Wiggins argues core personality traits influence interpersonal life



Two dimensions


-dominace and love


-cold hearted (communion)/ warm agreeable


-dominace (agency)/ submissive

What was the first lexical approach

Allport


-diffrrnetiated between personality traits, temporary states and activities


-traits are units of personality based in nervous system



4506 trait terms of personality

Allport 3 different personality traits

Cardinal traits


- express dispositions that are so pervasive that virtually every act is traceable to it



Central traits


-5 to 7 traits that reflect more limited ranges of situations



Secondary disposition (attitudes)


-traktd that thr are least obvious, generalized and consistent

Factor analysis (measurement approach)

Statistical technique that mathematically identifies meaningful underlying relationships amoung a set of correlated variables

Factor analysis steps

Collect data


Look at the pattern of correlations among the answers to different questions (items)


-doesnt answer why the responses are related



Computer organizes item correlations into clusters of items (factors) that are similarly correlated



When all correlations are accounted for the process



Factors in factor analysis

High and positively correlated items are placed in first factor



Weakly or negative items correlated with items in the first factor but instead correlated between themselves are placed in second factor

Three factor theory (Eysenck) PEN model

Introversion - extroversion



Emotional stability - Neuroticism



Psychoticism


-captures abnormal qualities in relatively normal individuals



Measured by Eysenck Persinality Inventory (EPI)



Additional narrow traits


Sub facets

What Is psychoticism

Reflects aggressiveness, lack of empathy, interpersonal coldness, ego centrist and anti social behavior

Bandwidth fidelity issue

?

Construct validity for the big 5 rests on factor analysis of 3 types of data

1) lexicon studies analysis of trait terms in the natural language


2) cross cultural research


3) Q data

What is Q data

Relationships between questionnaires that assess the big 5 in other questions

Know

Big 5 are necessary for a taxonomy or description of individual differences

Lexical studies

Individual rate themselves on a variety of traits sampled from a dictionary



Ratings are factor analyzed to find out how many factors are needed to understand the corrections between trait ratings


The big 5 (OCEAN)

Neuroticism


Extraversion


Openness


Agreeableness


Conscientiousness

Fundamental lexical hypothesis

The most important individual difference in human transactions will come encoded as single terms in some or all the world's languages

NEO personality inventory revised (personality questionnaires)

Measures 5 factors and 6 narrower facets (small components that make up big 5)



Each facet measured by 8 items (240 items)



Agrees with other big 5 instruments

Cattells 2 kinds of traits

Surface traits


-are clearly observable



Source trait


-the cause of surface traits

Cattells theory of personality

Identified 40 groups of correlated observations each represented by a surface trait


-came from Life data



Was interested in the structures that gave rise to surface traits



Further analysis lead to the development of 16 source traits


-these were measured by the 16 personality factors (self report test)

3 different types of source traits

1) ability traits


-skills that allow the person to function effectively (intelligence)



2) temperament traits


-involvr emotional life and stylistic qualities of behavior (calm vs emotional)



3) dynamic traits


-striving and motivational aspects of personality (self control)

NEO personality inventory correlated with 3 traits measured by Eysenck PEN model and Cattell 16 personality factors

Eysenck extroversion and Neuroticism are virtually the same in the Big 5



Eysenck Psychoticism corresponds to low agreeableness and low conscientiousness



16 personality factors yields thr big 5 factor structure

Unique features of five facotr model

Triats are not just descriptions of personality but are causal factors that influence the life course of everyone

General personality factor (GPF) Musek

All human personality can be explained holistically like g in intelligence



Postive aspects of 5 factor model plus two higher order factors

Two higher order factors in GPF

Alpha


-emotional stability needed to get along with others


-agreeablness, conscientious and neuroticism



Beta


-flexibility to adapt to changes and challenges


-exttoversion, openness



Have genetic origin and evolutionary importance

HEXACO Model (6 factor model)

Extroversion


conscientious


openness


neuroticism


Agreableness


Honestly/ Humility (genuine, trustworthy, integrity, moral)



Temperment traits N in the FFM are in A


Sentimental trials in A in the FFM are in N



Honestly/ humility dimension predicts outcomes not in FFM like dark triad

What are the facets of Honeslt/ humility scale

Sincerity


Fairness


Greed avoidance


Modesty

High and low scores in honestly and humility

High scored people -peoppe avoid manipulation of others, not interested in wealth, no entitlement, doesn't take advantage of disadvantaged, doesn't break rules



Low scored people


Will flater others to get what they want, break rules, motivated by wealth, feel self importance

Big 7 model (tellegen and waller)

Same as big 5 with two additional factors


-postive valence


-negtive valence


(Represent states like moods)



Understand pathology within the normal range and the dark triad

As to thr adjective, when in doubt strike it out

Elimination of adjectives thar describe physical characteristics, demographics, unusual behaviors and adjectives not typically used to describe behavior produces 10 possible candidates


(Pic)

Is intelligence a personality trait

Maybe not


-intelligence related terms and adjectives loaded on openness, culture and conscientiousness



-self and peer ratings on personality differ from IQ



-IQ is different from traits

Is religiosity a personality trait

Undetermined



-religiosity is a secondary trait reflected by combinations of A, C and sometimes O, E



-spiritual transcendence is only slightly related to big 5



-6 factors found when big 5 and transcendence scores were analyzed together

Is sexuality a personality trait

Doesn't look like it


-sexy 7 (Buss) measures descriptors of personality relating to sexuality



-early research: sexuality descriptors restricted to one gender



-can be accounted for by combinations of A, E , O and N facets

Sexy 7

?

3 approaches for studying personality in crossed cultural perspective

Methodological


- emic and etic distinction



Lexical



Interview methodology

Emic and etic distinction ?

Languages may lack one to one translations



Dont know if same factor is found two languages or if an imposed etic on culture because trait terms don't arise spontaneously in the language



-avoid transport test approach (back translation methods)

What did Hofstee do

Identified 126 words that can be translated directly from English to Dutch and German



-found congruence across all three languages except for openness factor



-german and English have similar factor structure



-in Dutch opened included traits of rebelloiusness



-similar variations on openness found in Hungarian and Italian

Emic factors and big 5

Some culturally specific personality factors are not captured by big 5



Ex. Status and family relations not measured by big 5 in Asian cultures


-Chinese: filial piety (family responsibility, honor)


-jappanese: amae (dependency, dependable)


-Korean: cheong (human affection)


-saving the WA (don't embarrasse famiy)

Di Blas and Forzi

Explored the structure of personality terms in Intalian by selecting items directly from Italian dictionary (lexical study)


-ask idnvidiuals to rate themselves


-see if big 5 would replicate



Found 3 out of 5


-extraversion


-agreeablenss


-conscientiousness



Neuroticism not identified

China cross culturally and Big 5

Chinese and American college students showed identical results except for the facet of openness

Cheung (1996)

Developed the Chinese personality assessment Inventory (CPAI)


-a measure of 10 trait clusters unique to Chinese personality

Cheung (2001)

Administer the NEO personality inventory reverse and Chinese personality assessment inventory to analyze results together



-6 factors (big 5 and cheung: interpersonal relatedness)

Interpersonal relatedness

Reflects traits encouraged in Chinese culture


-maintaining harmony


-avoiding conflict


-flexible in situations


-saving face



In other Asian and American samples

Cross culturally triats in South Africa

Ubuntu


-emphasizes social relatedness, peace and harmony in collective community based environment



-tolerance, compassion, sensitivity, loyalty, warm, trustworthy



-obedience and respect toward adults parents teachers seniors and authority

Nel, Valchev and Rothmann (2012)

Used lexical study to examine Ubuntu amon English, Afrikaans and 11 south African language groups



-found in all language groups in trait clusters representing relationship harmony, softheartedness, facilitating goals

Alternative study to previous

Study of Ubunto and NEO PR



Two large superordinate traits emerged


1) person centered (contained big 5)


2) relationship centered (corresponding attributes of Ubuntu)


-emic personality traits


Zeinoun, Choueiri and DeVijver (2017)


(Example of cultural specific (emic) factors)

Study of personality dimensions in modern standard Arabic


-806 participants



167 personality traits that are familiar and common in Lebanon, Syria, Jordan and West Bank



Reveled 6 factor solution


Reflected facets of big 5 and HEXACO model and narrow culturally specific personality traits


Zeinoun, Choueiri and DeVijver (2017) 6 factors

1) morality


2) conscientiousness


3) postivie emotionally (low N, high E)


4) dominace


5) agreeablness/ righteousness


6) emotional stability (low N)

DeRaad and Peabody (2005)

Examined trait terms across 11 languages



big 3 (extraversion, agreeablness and consciousness) are cross lingual recurrent


-neuroticism and openness are less cross culturally reliable



replication of full big 5 is questionable

What does openness vary across cultures

1) Defintion


Lexical studies: defined as intellect and imagination


Self report measures (NEO PI): defined as open to novel experiences, people and events



Exists cross culturally but dinfied in a unique way to each culture (emic concept)

Why are there more than 5 factors in some cultures

1) extra dimensions may tap into social evaluation (power, morality)



2) interpersonal relations are so important that there are many trait terms to describe relations



3) in some cultures, culture specific dimensions are captured in combinations of extraversion and ageeeablness

Web pages and Big 5

Bloggers are high in N and O


-observers reading blogs related N,O, C of bloggers


-E and A ratings reflected bloggers ideal self ratings



High E individuals bloggers to more online groups



Introverts spent more time on Facebook and more postive about it

Seidman (2013)

Found that high C individuals were more cautious in their online presentations



High A and E individuals were more likely to express their actual triats



High N positively associated with the expression of ideal hidden selfs

Sorokwaska (2016)

E predicted the frequency of online selfie posting



Weak evidence of relationship between self esteem and selfish posting

Kaurin (2018)

Observers rate personality of those who posted on social media



Agreed and their ratings were correlated with a criterion measure of target personality



Accuracy correlations were higher when based on selfies than brief introductions provided with selfies


(Expcet agreeablness and self esteem)

Research strategies to measure age differences throughout adulthood

Longitudinal: individual change


Cross sectional: mean level change

Age and personality

Stability over long periods (increases with age)



No period of dramatic personality change



Personality coherence rather than incoherence



Big 5 are most consistent starting at age 3 and until 5



Evidence of some change is found (small Gradual changes)

Rank order correlations remain significant

30% of variability at a later age can be predicted from responses at an earlier age

Bazana and Stelmack (2004) means of stability coefficients for big 5

N: 0.52


E: 0.59


O: 0.52


A: 0.48


C: 0.50

Schwada and Bleidorn (2017) study of 9636 Dutch participants

Provided with big 5 self reports at 5 assessments over 7 years



Individual differences in personality change were small but significant until old age



O, C, E, A Individual differences in change were most pronocuded in emerging adulthood and decreased midlife and old age



N Individual differences in change were relatively consistent across life span

What does consistency or continuity in personality mean

Level of trait remains thr same over time



Personally change means an increase or decrease in level from previous levels and then stability



Change is often one of degree not kind

Trait change can occur in

1) a group of people over time (mean level change)



2) how a person changes over time (individual rank order level change)



3) change compared to same age peers or refetence group (relative rank order level change)

Rothbart and Bates (2006) personality in children

Suggest that temperament froms thr affective core of later personality and predicts a wide range of childhood and adolescent traits

Temperament

Defined as individual differences in emotional reactivity and regulation


- relatively stable and partially genetically based


-environmental factors do contribute

3 temperaments present in fincacy that form the basis of adult extroversion and Neuroticism

1) Emtionality (N)


-N is more of a personality trait



2) Sociability (E)



3) Activity level



- Agreeablness doesn't emerge till 8


-is hierarchically organized and can be measured reliably

Difference in adult vs childhood

A and C, C and O are strongly correlated in childhood but become independent in adulthood



C and O underlie traits of self regulation and self mastery

Barbarnelli BFQ- C measure

Made of 65 traits reflecting the constructs of neuroticism, extroversion, openness, agreeablness and conscientiousness

Large crossed culture study by Takett, Slobodsky and Mar (2012)

Found that only E A and O replicated across culture and age groups of 8 to 14

How stable are the attributes in children.

Evidence of rank order stability (cumulative-continuity principle)



Evidence of Disruption hypothesis



Little evidence of maturity principle (increases with age in the meal level of A, C and E)

Disruption hypothesis

Biological social and emotional changes during development are accompanied by personality change

N and gender differences

Little difference in children



Adolescent girls become prone to negative affect and increasing N



Boys show little change in N with age

Sobodskaya and Kornienko (2021) cords cultural difference in children's personality development

In childhood A, C and N increase while E and O decreased



In adolescents parents report increases in C and decreases in N


-youth rated Alpha and A decreases



Personality maturation happens from childhood to late adolescence except N


Personality change in adulthood

Assumption of the big 5 theory that personality change is set by 30 is premature



-Robert concluded most change happens 22-30 (young adulthood)


-there was no evidence of gender differences on any personality dimension or within any age cohort


Shrivastava (2003) cross sectional study using internet respondents

Similar to Robert but...



Women but not men are more emotionally stable after age 30



Older men had the same level of emotional stability as young men



Openness declined with age for everyone

Why might personality change in young adulthood

1) life experiences can change E, C, N



2) demands of age- graded social roles and expectations


- tasks like finding a partner and getting a job can set the stage for changes

Barrick and Mount (1991) Personality and career choice

Found C alone was related to performance ratings, productivity, salary and low job turnover


-held across gender and occupations


-being extravered was helpful for people on management and sales

Sackett and Walmsley (2014) personality and career choice

Attributes related to C and A were important across many jobs


-ranging in compexitiy, raining and experience

Serrat, Villar, Pratt and Stuckas (2007) personality and retirement

Assessed big 5 and general activity before retirement in the prediction of hedonic and eudaimonic well being at two points of retirement



N - Eudaimonic well being


E and General activity- hodonic well being

Eudaimonic well being and hedonic well being

Eudaimonic


-idea of pursuing one's goals, realizing ones potential and feeling that one's life has purpose and meaning



hedonic


-being satisfied with life and experiencing high levels of postive affect

Hansson, henning and Buratti (2019)

Examined the relationship between big 5 and adjustment to retirement


(Look on snap)

Asselman and Specht (2021) examined personality changes that happen prior to retirement and shortly after

C was higher in first years of work versus later



E was higher in and after first yeas of working



A increased gradually in the 3 years after starting work



C was lower in and after first year of retirement verse before


-no other traits differed around start of retirement

Friedman (1993) and longevity

Children rated high in C in 1922 were more likely to be alive in 1990


-live longer cause C people engage in self care acts that reduce illness/ disability


-better coping skills that reduce stress



Those rated as Agreeable (happy/ cheerful) in 1922 were likely to be dead by 60


-promte faster recovery but determental to life long personality characteristic

Argeeableness and short life

Agreeable people may underestimate risk factors, fail to follow medical advice



Poor coping skills


-may not know how to handle stress and have difficulty breaking out of bad habits that got them their

Spengler (2014) personality and health

Examined the relationship between self and teacher rated student traits assessed at the end of primary school with all cause morality rate at 52


-self ratings on responsible student scale


-teacher ratings of studiousness



Predicted all cause morality even after controlling for IQ, SES and gender



Results show self and observer estimates on triats reflect C predict longevity and low morality

JOKELA (2019) examined the relationship between big 5 and healthy life years lost and population

Low C was associated with high mortality


-only when it was below median level



Low emtional stability was related to shorter life expectancy


-only among those in the lowest 15% distribution

Gale (2017) N and longevity

Explored relationship between N and self rated health



1 SD increment in N was associated with 6% increase in mortality



After adjusting self rated health, high N was associated with 8% reduction


-only if those people with fair or poor self rated health

Mund and Neyer (2015)

Assessed big 5, measures of subjective health and loneliness in German adults at two pints in time 15 years apart



N precise both subjective heath and loneliness

Ogle (2016) N increases risk of PTSD

Increases in thr level of N assessed in young adults and then in midlife reported trauma memories



N leads to PTSD symptoms by magnifying the emotional level, availability and centrality of trauma related memories

C financial well being

Trait associated with high levels of motivation, goal setting, financial planning/ success



Suffer more when experience financial services backs, doubt abilities


-low C contribute set backs to lack of effort or bad luck

Boyce and wood (2016)

C is positively related to loss aversion


-high C sees loss as more devastating


-C people are more risk aversive

Loss aversion

The heuristic to evaluate losses as being more meaningful and more negative than positively values gains

Extrovert advantage

Have higher quality social interactions, are better at creating favorable impressions and establishing rapport

Duffy and Chartrad (2015) extroveet advantage

Filmed extrovers where they were judging photographs or completed a word search tasks while interacting with someone



Extroverts mimic other people when it is highly adaptive to do so


-use to.bulid rapport particularly only when they have a goal to affiliate



Supports that extroverts are more reward sensitive than introverts

Leikas and Iiimarinen (2016) costs of E and C

High scores had more postive moods at the start of the study but were mentally depleted 3 hours later



Depletion was postively related to the number of interaction partners during the day
