important deck Flashcards
Roberts, Walton and Viechtbauer (2006)
meta analysis of 92 samples from 15-65. Emotional stability increases until 30, then it is stable for life Social dominance (part of extraversion) increases until about 50. Dcrease in sociability extraversion throughout life. Openness to expeirneces increases till about 30 then slightly decreases. Agreeableness increases throughout life. Conscientiousness increases throughout life
Robert et al (2006)
Personality traits change most between 20-40 years
McCrae et al (1999)
changes across cultures. Different cultures different amount of changes e.g. in Croatia major change from 18-21 to 21+ but not that much change in Portuguese in the personality trait extraversion
McCrae and Costa (1999)
humans have genetic predisposition to dvelop in certain directions, hard-wired to become more socially dominant, agreeable, conscientious, emotionally stable and less open to experiences
social investment hypothesis
Roberts, Wood and Smith, 2005): investment in universal tasks of social living (job, marriage…) similar tasks supported in most sultures. Normative experiences associated with increases in personality traits of social dominance, agreeableness, conscientiousness and emotional stability
Main things to influence our personality:
self-conceot, characteristic adaptatios (attitudes, goals…), biology and external influences
why are we more narcissitc
taking more selfies…
Raskin and Terry (1988):
narcisstic personality inventory. Theyre charming, everyone wants to hear my stories, people seem to recognize my authority, I find it easy to manipulate people. Types of narcissism: pathological (vulnerability component, need good feedback), grandiose
what did Costa and McCrae do?
found r=.70 slef reports of adults/observers 6 years apart, r=.65 24 years apart
by Robins and Trzesniewski (2005)
men on average have higher slef esteem then women. Originally have same at the about 7. But during school goes down till 18 lowest point. Then increases till 65 (highest). Higher than men at 85
Lamb et al (2002)
openness to experience flutucates a lot from 2-15. Extraversion &neuroticism increases, agreeableness and conscientiousness remain high
Hawiaan studies: Edmonds et al, 2013
Found early childhood doesn’t predict later childhood
SOKA-model (Vazire, 2010)
self is better at reporting low observability low evalutiveness, when high observability or high evalitvieness observer report is better.
Mishel et al (1988
delay gratification, when 4/5/6 year olds get left alone with marshmellow and told if wait 15 minutes get another and can eat both 2/3 cant wait to eat it. Later in life seen to do better if more self discipline when younger
what is personality?
a set of psychological traits/mechanisms within the individual that refer to the differences among individuals and they way they think/feel/behave, across a fairly long period of time and a range of situations
what is reliability
The degree to which a measure produces consistent results
Does the obtained score represent the ‘true level’ of the construct being measured?
what is internal-consistency reliability
The extent to which the items of a measure are correlated with each other
what is inter-rater reliability
The degree of agreement between the scores of different raters/observers
what is test retest reliability
The degree of consistency between scores across different measurement occasions
what is validity
The extent to which a test measures what it claims to measure
what is content validity
The extent to which a measure assess all relevant features of the construct, and does not assess irrelevant features
what is construct validity
The measure assess the same construct that it is intended to asses
- Convergent validity: correspondence with measures assessing similar (positive relations) or opposite (negative relations) characteristics
- Discriminant validity: correspondence with measures assessing characteristics unrelated to the one the scale is intended to measure
what is criterion validty
Relations with relevant outcome variables; also called predictive validity
what is the fundamental lexical hypothesis
“The most important individual differences in human transactions will come to be encoded as single terms in all of the world’s languages”
more than 5000 words to describe traits
what is Cattells 16PF
factors with low high scores to see what personality traits you have e.g. warmth, intellect, reasoning, emotional stability, dominance, liveliness, rule-consciousness, social boldness, sensitivity, vigilance, abstractness, privateness, apprehension, openness to change, self- resilience, perfectionism, tension
what is EFA?
exploratory factor analysis. Data reduction technique: aims to determine the number and nature of “underlying factors” that explain a pattern of correlations between large numbers of variables
Generates hypotheses e.g. shy, anxious and tense all measure the same things as highly correlated so 1 factor
whats CFA?
confirmatory factor analysis. Statistical technique for model testing
Tests hypotheses
whats EN theory of personality?
By Eyesneck. two superfactorys (extraversion-introversion and neurotcisim-stability)
what is the PEN theory of personality
Eyesneck later added the superfactor Psychoticism (extraversion, neurotics)
what is the hierarchical organisation of personality
superfactor at the top, its traits, habitual response level then specific response level.
how many factors should be in a factor analysis for personality?
5 (tested on different cultures, nations, languages)-Goldberg
what is the big five/five-facotr model of personality

whats mean level change
an absolute change in the individual’s level of a certain trait over time. Longitudinal research shows that mean-level change does occur.
Roberts, Walton, & Viechtbauer (2006)
social aspects of extraversion decrease throughout lie, but assertive increase. conscientiousness, emotional stability and openness all increase still about 30 then stay constant, agreeableness increases until 50.
change most from 20-40
what did McCrae et al 1999 show
differences across cultures. e.g. croatians are the most extraverted whilst Germans are the least. croatians are least conscientiousness and Germans are the most, out of 5 countries
why do we change?
Humans have a species-wide genetic predisposition to develop in certain directions
• Hard-wired to become more socially dominant, agreeable, conscientious, emotionally stable, and less open to experience
what influences the personality
biological causes, characteristic adaptations, self-concept, external influences e.g. norms,…
what is the social investment hypothesis
(Roberts, Wood, & Smith, 2005)
Investment in universal tasks of social living (e.g., getting a job, being married)
• Similar tasks supported in most cultures
• Normative experiences associated with increases in personality traits of social dominance, agreeableness, conscientiousness, and emotional stability.
what is the narcissitic personality inventory
e.g. im an extraordinary person, everyone likes to hear my stories… superiority and self-sufficiency
what did costa and McCrae (1988) find
self-reports of adults personality 6 years apart r=.70
same with observer reports in 1992
what did Costa and McCrae (1992)
self reports of adults 24 years apart r=.65
what did McCrae wt al 2002
12-16 r=.40 (.50 for C)
Robins and Trzesniewski 2005
at 7 same self etseem. lowest peak for both is 18 years. females lower self esteem than boys until 80 where have more
Lamb et al 2002
all of the big five increase in childhood, neurotics mainly increases when school starts. through childhood from 2-15 about r=.2
what are the Hawaiian studies
45 year personality correlations. all correlated bar neuroticism.
what di Vazire 2010 find?
when low observability low evalutiveness e.g. anxious . if high observability on either of these observers are better
what did Mischel et al 1988
delay of gratification. one marshmallow now to two later. those who had more self control later were likely to wait then (more likely to go to uni…) 4 years old
what are the four main humours
used in Acient Greece blood-cheerful- sanguine black bile-depressive- melancholic yellow bile- angry- choleric Phlegm-calm-phlegmatic no empirical evidence
what were the four kind of dogs temperament Ian Pavolv found
weak- anxious- melancholic
strong unbalanced-irritable/ choleric
strong balanced slow- calm/phlegmatic
strong balanced mobile- lively/sanguine
about dopamine
transmission of signals of reward, in response to things that feel pleasurable and exciting
Cloninger: personality characteristics related to one’s response to pleasure and excitement
does parkinson’s or cocaine have excess dopamine?
cocaine- increase novelty seeking. PD have lack of interest in new/fun activities, uncoordinated movements
about serotonin
inhibits the transmission of signals of punishment, preventing neurons to send message in response to things that feel harmful or unpleasant. low levels are high in harm avoidance (fear of uncertainty…)
• Cloninger: personality characteristics related to pain and anxiety
what drugs can make serotonin system more active
Prozac/paxil
Inhibition of transmitting punishment signals
Reduction of negative emotions such as anxiety and depression
what is norepinephrine
noradrenaline) inhibits the transmission of signals of responding to stimuli that in the past have been associated with reward
~ signals of conditioned reward
• Cloninger: personality characteristics related to people and things that have been associated with pleasure
low levels of norepinephrine = high in “Reward Dependence”
what happens if you are low in norepinephrine?
e tendency to develop strong sentimental attachment
what is Grans theory?
Reinforcement Sensitivity Theory (RST)
- Brain regions work together as systems that underlie personality
1. The Behavioural Activation System (BAS) 2. The Behavioural Inhibition System (BIS) 3. The Fight-or-Flight System (FFS)
what is BAS?
Brain regions responsible for receiving signals from the nervous system which indicates that rewards are being experienced
- Go-system: encourage pursuit of rewards, communicating the pleasurable and exciting nature of rewards
stronger system=want rewards more - novelty seeking
what is BIS
Brain regions responsible for receiving signals from the nervous system which indicate that punishments are being experienced
- Stop-system: encourage avoidance of punishments, communicating the painful and frightening nature of punishments
stronger system more avid punishment, more anxious…
what is FFS?
fleeing
- In response to extremely threatening situations
- People differ in the sensitivity of their Fight-Flight system: Stronger or more sensitive system = more ready to fight or to flee in case of emergency
~ showing extreme reactions: aggressive response, leaving hurriedly
~ some researchers suggest that there might be a negative link with Cloninger’s Reward Dependence dimension but there is not yet empirical evidence showing such association
what is Ascending reticular activating system (ARAS)
ARAS is located in the brain stem, where the spinal cord meets the brain
- Nervous system receives stimulation from the environment
- ARAS regulates the amount of stimulation that is admitted to the brain from the nervous system
- If one’s ARAS allows little stimulation, one feels underaroused and thus seeks stimulationextraverted personality
- If one’s ARAS allows admits a lot of stimulation, one feels overaroused and thus avoids stimulationintroverted personality
what is in control of neurotcism
lymbic system
One of its functions is to regulate stress responses
- People with a limbic system that is able to manage stressful stimuli, are more emotionally stable
- People with a limbic system overwhelmed by stressful stimuli, tend to be more neurotic
what are higher levels of psychotosim associated with
Very psychotic people are aggressive, cold, egocentric, impersonal, impulsive, tough-minded, antisocial
~ High levels of psychoticism are associated with criminal behaviour, mental illnesses, but also with creativity
High levels in psychoticism are associated with higher levels of testosterone and low levels of the enzyme mono-amine oxidase (MAO)*
whats the lemon juice test by Eyesneck and Eyesneck 1967
eeded: - Lemon juice
- Cotton wool balls
- Kitchen scales
Need to do: - Drop lemon juice on your tongue
- Mop up all the saliva you produce using the cotton wool balls - Weigh the balls and compare your result with the result of others
Eysenck: the stimulation produced by the lemon juice is perceived more strongly by introverts than by extraverts
Result (Eysenck & Eysenck, 1967): Introverts produced more saliva than extraverts
Geen (1984)
Extraverts in the choice condition will prefer higher levels of stimulation and thus choose louder noises than introverts in the choice conditions (intensity settings ranged from 0 to 100)
confirmed by the results: Mean settings of intensity was 37.3 for the introverts and 54.2 for the extraverts. Introverts prefer lower levels of stimulation than extraverts
2. Introverts are more aroused / react more strongly than extraverts under equal levels of stimulation
