theory of personality and individual differences Flashcards
how can one describe the term personality?
comes from ‘persona’ meaning ‘mask’
stable concept but also evolves as we mature and gain new experiences
summarise essence of individual which is consistent over situations and time
what does the study of individual differences actually study?
the ways in which people are psychologically similar and psychologically different
brief origins of personality psychology?
traced back to greek philosophers
interest in individual differences split off psychology from philosophy
briefly explain what phrenology is?
Franz Gall claimed lumps on the skull reveal character traits and mental abilties
what are the 2 main camps in modern personality psychology and which approaches branch out from them?
- scientific - trait, behaviorists and social learning theorists
- clinical - psychoanalysts, humanists and existentialists
briefly describe the psychoanalytic approach to personality?
unconscious mind & motivations
resolving internal conflict
focus on childhood trauma leading to fixations shaping personality in adulthood
briefly describe the trait approach?
conceptualising and measuring how people differ
continuum of trats and behaviours
briefly describe the biological/evolutionary approach?
anatomy, physiology, inheritance and evolution
inherited predispositions
briefly describe the phenomenological/humanistic approach?
conscious experience of the world
personal responsibility and self acceptance
qualitative methods as focused on subjective experience
briefly describe the learning approaches?
behaviourism, social learning theory and cognitive personality theory
learning helps to adapt behaviour view rewards and punishment
briefly describe the cognitive approach?
role of perception and memory
different ways in which people process information
what 4 factors to look at when evaluating a philosophical theory?
- coherence
- relevance
- comprehensiveness
- compellingness
what are the 6 factors which make a theory useful?
- generates hypotheses and research
- falsifiable
- integrates existing data
- suggests practical answers to day-to-day problems
- internal consistency
- simplicity/parsimony
which 2 cultural contexts exist and what personalities are associated with this?
individualistic
- individual needs and competition
- have ‘i’ orientation
- autonomy and equality
collectivist
- cooperation and groups
- ‘we’ orientation
- tradition and hierarchy
when are situational variables / personality traits best suited to predicting behaviour?
in regards to the person-situation debate
personality traits - predict patterns of beh. across situations and time
situational variables - predict beh. in specific situations
what is the Forer/Barnum effect?
example of data supporting this?
people accept vague and general personality descriptions as uniquely applicable to themselves
even if questionable/false if deemed positive/flattering enough
as shown by average of 4.2/5 when rating how accurate personality description was about them
what are psychometrics?
and what is including in psychological psychometric testing?
psychometrics - theory and methods of psychological measurement
include intelligence testing, measurement of personality traits and vocational testing
a few background facts about Sigmund Freud?
work? studies? published?
- specialised in treatment of nervous disorders
- studied hypnosis and the ‘talking cure’ which he used in his own work and is now the basis of psychological therapy
- published the interpretation of dreams in 1900 introducing concept of unconscious
- developed first comprehensive theory of personality
what are the 6 key assumptions of Freud’s psychoanalytic theory?
- psychic determinism - everything in person’s mind and actions has specific cause
- unconscious instinctual urges - driven by unconscious animalistic urges
- structure of mind - divided into 3 (ego, id, superego)
- psychic conflict - personality characteristics determined by how person overcomes conflicts between id, ego and superego
- psychic energy - must be expressed and 2 drives of eros/libido - life & sexual instincts and thanatos - death instinct
- psychoanalytic therapy - relieve conflicts by providing insight into unconscious
what is involved in the topographic model of personality?
3 levels of awareness (ego floating in all 3):
- conscious - current awareness
- preconscious - below surface of consciousness but accessible (superego)
- unconscious - not voluntarily accessed (id)
what are the parts of the structural model of the mind/personality?
- id
- ego
- superego
describe the id?
primitive irrational mind
based on pleasure principle
unconscious
describe the ego?
rational part of the mind
based on the reality principle
negotiates compromise between the id and superego
describe the superego?
the moral part of the mind (the conscience)
embodiment of parental and social values
describe the cause and result of intra-psychic conflict?
interactions betwen 3 structures of personality create intra-psychic conflict
conflict can result in anxiety
how is intra-psychic conflict dealt with?
defence mechanisms
what and when are the 5 psychosexual stages of development?
- oral (0-18 months)
- anal (18-3 1/2years)
- phallic (3 1/2-6 years)
- latency (6-puberty)
- genital (puberty-adulthood)
what are the 3 parts to each psychosexual stage?
a physical focus
a psychological theme
an adult character type (depends on whether fixation occurs whereby trauma during stage leads to exhibiting pos/neg characteristics of that stage)
what are the 3 parts to the oral stage of development?
- physical focus - mouth
- psychological theme - dependency
- adult character - extremely dependent or independent (stressful times may lead to oscialltion between the 2)
what are the 3 parts to the anal stage of development?
physical focus - anus
psychological theme - self control / obedience
adult character - highly self-control and subservient to authority (anally retentive)
little self-control and hostile (anally expulsive)
what are the 3 parts to the phallic stage of development?
physical focus - penis
psychological theme - sexual identification : Oedipus and Electra complex
adult character - promiscious or asexual
what occurs during the latency stage of development?
period of relative calm
what occurs during the gential stage of development?
physical focus - genitals
psychological theme - sexual reproduction, intellectual and creativity
adult character- well adjusted and balanced
list some defence mechanisms and explain why they are used?
denial repression regression reaction formation sublimation projection rationalisation intellectualisation displacement
used to deal with anxiety caused by conflicts between 3 structures of personality
briefly explain the defence mechanism of denial?
stating an anxiety provoking stimuli doesn’t exist (can be unconsciously done)
briefly explain the defence mechanism of repression?
pushing anxiety into unconscious (intentional and takes a lot of energy)
briefly explain the defence mechanism of regression?
returning to a previous stage of development e.g biting nails or having tantrums
briefly explain the defence mechanism of reaction formation?
taking opposite belief because true belief causes anxiety
briefly explain the defence mechanism of displacement?
taking out impulses on a less threatening target
briefly explain the defence mechanism of rationalisation/intellectualisation?
focusing on logic and intellectual aspects to escape real reason
briefly explain the defence mechanism of sublimation?
acting out unacceptable imulses in a socially acceptable way e.g humour
what are several forms of ‘evidence’ of the unconscious?
parapraxes (Freudian slips)
humour (controlled leak)
dreams (royal road to the unconscious as enable id to express impulses)
what are the 2 parts of dreams?
manifest content - what we see and remember
latent content - what is really being said (Freud interprets majority as sexual)
what is the aim of psychoanalytic theory and what are the main techniques?
uncover repressed, unconscious material to release pent-up anxiety inducing emotions
- dream analysis
- free assoication
- transference and counter-transference
what is meant by transference?
and counter-transference
transference - when client transfers feelings about something/someone to therapist
counter-transference - when therapist develops pos/neg feelings for client
what are 3 examples of projective tests to measure unconscious material
project unconscious onto interpretive task
Rorscach inkblot test - describe what ou see
thematic apperception test (TAT) - tell story about picture
human figure drawing test - draw pic for therapist
list some strengths of Freud’s theory?
1st comprehensive theory on behaviour and personality
emphasises role of unconscious and early childhood
stimulated lots of research
developed first system of psychotherapy
list some old evidence in support of Freud’s theory?
defence mechanisms esp. repression occurs (Weinberger & Davidson, 1994)
lab studies have demonstrated transference (Andersen & Baum, 1994)
list some criticisms of Freud’s theory?
hard to test empirically
role of enviro overlooked
focus on heterosxual male beh. as norm
evidence to criticise Freud’s theory?
Eysenck (1952)
found inverse correlation between recovery and psychotherapy
difference between the trait theory and the type theory?
trait - continuous and categorises people based on degree they manifest particular traits. unique personalities explained by certain degree to which they have traits
type - categorical and assumes that we all fit into a personality category and all in that category as alike
what is the definition of character?
personal characteristics that have been judged
what is temperament?
hereditary aspects of personality i.e arounsal system including moods and irritability
what is McCrae & Costa (1990) definition of a trait?
dimensions of individual differences in tendencies to show consistent patterns of thoughts, feelings and actions
what are the 3 main assumptions of the trait approach to personality?
- personality differences between people as although we all share the same traits, we all express them to a certain degree which shapes our personality
- traits are stable across time and situations
- traits are independent of one another (type approach suggests they are clustered)
how are traits distributed and what does this mean?
normally distributed meaning fewer people score in extreme on any trait
how does the trait continuum work?
any characteristic can be illustrated with this continuum
two opposite traits lying on each side and person can be placed in between them
what are the 4 ways traits are studied?
- typological approach
- single-trait approach
- many-trait approach
- essential trait approach
how does the typological approach study traits?
attempts to put people in distinct categories using certain clusters of traits
how does the single-trait approach study traits?
focuses on one personality trait to explain a range of important behvaiours e.g aggression
how does the many-trait approach study traits?
what test does it use?
focuses on many traits and correlates these with behaviour
california q set measuring traits one possesses and can predict complex behaviours later on
how does the essential trait approach study traits?
reduces ‘many traits’ to a few that are essential to understanding personality and individual differences (most prominent today)
e.g the Big Five and Eyesenck’s extraverion, psychoticism and neuroticism
underpined by psychometric theory and factor analysis
what are the highlights of Allport’s theory?
personality is dynamic as motivations change (adult=growth, child=tension reduction) - fucntional autonomy
hierarchical organisation - a few traits can explain most behaviour
conscious values shape personality (not same as Frued)
lexical approach - all important traits captured by language
what is the difference between the idiographic and nomothetic approaches to personality measurement and description?
idiographic - non-comparability between individuals as all have unique combination of traits which should be looked at e.g self report and interviews
nomothetic - comparability aong individuals along same personality traits
what is the morphogenic approach to personality measurement and description?
Allport blending idiographic and nomothetic by looking at the individual wihin a certain group
what are central, cardinal and secondary traits according to Allport?
central - traits in combination organise most of person’s behaviour
cardinal - dominant trait that influences behaviour
secondary - not often exhibited traits which may influence some behaviour
what is meant by ‘common’ traits?
within any culture there are common traits that everyone recognises and identifies
share due to common biological and cultural heritages
what is ‘proprium’?
organising structure of personality
responsible for self-esteem and image
what is meant by the term ‘projective test’?
indirect way of measuring personality by examining reactions/interpretations to certain stimuli with the aim of accessing unconscious as reflects their inner needs etc.
e.g inkblots
wat is meant by objective/psychometric tests?
tests which require people to answer very specific qs about their personality
e.g EPQ
what are several issues with reliabilty and validity in the Rarschach inkblot test?
reliability - same person might interpret same picture as different on different days depending on mood and same with person testing, also quite subjective in marking as well so different experimenters would view differently
validity - might be testing mood not constant personality traits, also subject to social desirability bias/lying especially when in high pressure situation lie diagnosis or court case
what are the 3 main reasons people dissented from Freud’s ideas?
and what are the counter proposals?
- pessimistic - controlled by unconscious forces instead proposed teleological (behaviour=goal directed)
- adult personality shaped by childhood experiences - proposed adolescence and early adulthood important too
- over emphasis on role of unconscious - instead proposed social and cultural influences
describe Carl Jung’s alternative theory and what is the name of it?
Analytic psychology
teleological view - personality development continues throughout life and is influenced by future goals as well as past
anima (feminine side of male) and animus help in choosing best corresponding romantic partner
conscious ego, personal unconscious and collective unconscious (inherited content predisposing us to look at world in certain way called archetypes)
contribution of Jung to personality psychology?
archetypes and collective unconscious interpreted as our naturally born instincts - not born blank slates
theory of traits resulted in Myers-Briggs Type Indicator
developed word association test
describe Alfred Addler’s alternative theory and what is the name of it?
Individual psychology
striving for superiority is motivating force and if fail then inferiority complex
birth order - middle best, oldest dethroned and youngest inferior
parenting styles- pampering = overprotection leading to doubting abilities and neglect = not protected leading to difficulty forming intimate relationships
describe Erik Erikson’s alternative theory and what is the name of it?
Ego psychology
teleological approach to ego as works towards goals and maintains sense of identity
personality development along lifespan and identity crisis focal point for each developmental stage (how we resolve this determines direction of personality development i.e adaptive or mal)
give some examples of Erikson’s 8 pscyhosocial developmental stages?
infancy - trust vs mistrust
adolescence - identity vs role confusion
young adulthood - intimacy vs isolation
describe Karen Horney’s alternative theory and what is the name of it?
Feminine Psychology
males and females differentiated and gender roles in place due to society and culture not just biological differences (biology determines sex, culture determines gender)
parenting - disturbances causes basic anxiety which can lead to alienation with ‘real self’ - dealt with by moving toward/against or away from people associated with 1/3 neurotic personality styles
what is involved in object relations theory?
superego develops from identifications as a child with important people
repeat psychological patterns learnt in childhood in new relationships through transference
object=person, relations
essence of who we are can’t be understood without understanding relations with significant others
what are the 3 approaches in trait identification and measurement?
- lexical - all relevant dimensions of personality exist in the natural language
- theoretical - start with a theory which guides selection of terms and question formation
- statistical (psychometric theory) - use factor analysis to guide selection of terms and questions - essential trait approach uses this
give some examples of psychometric testing?
(theory and methods of psychological measurement)
- intelligence testing
- measurement of personality traits
- vocational testing
describe factor analysis used in psychometrics?
statistical method allowing lots of data to be reduced into a few important factors
resulted in the Big Five
uses concept of correlation
briefly describe process of factor analysis?
- measure large number of people in varous ways using numerous items
- correlate scores with scores of every measure (correlation matrix)
- determine how many factors need to be hypothesised to account for inter-correlations (when high correlation then thought to masure same characteristics called factor/trait)
- subjectively decide meaning of each factor and label it
- standardise the personality measure (test people and analyse responses to develop norms which future scores are assessed against)
what is meant by test-retest reliability?
stability over time
measure by correlating scores from ppts who take test on at least 2 occasions (needs to be .8)
influenced by characteristics of subject and of test e.g poor instructions
what is meant by internal consistency?
in terms of reliabilty
whether all items are measuring the same thing
Cronbach’s Alpha (shouldn’t be below .7) but very high score indicates test too specific to be valid
strengths of psychometrics?
objective way of dscribing people and their behaviour
easy to administer
lots of quantitative data for statistical analysis
weaknesses of psychometrics?
having valid and reliable tests difficult
tests contain culture bias e.g intelligence tests
where did Cattell get his data from?
L-data : life data
T-data: test data
Q data questionnaire data
in Cattell’s theory, what are source and surface traits?
source - underlying causes of overt behaviour, basic elements of personality and cause of surface traits (16 of them)
surface - behavioural manifestations of source traits
what are Cattell’s 5 trait classifications?
- environmental-mold traits: determined by experience
- constitutional traits: determined by biology
- ability traits: ability to deal with complex situation e.g intelligence
- temperament traits: emotional tendencies determine general style of interaction
- dynamic traits: ergs (innate motivational traits) and meta-ergs (learned motivational traits)
what is the na,e of Cattell’s questionnaire measuring personality?
the sixteen personality factor questionnaire
185 multiple choice questions about daily behaviour and interests and opinions not self-assessment of own traits
correlation between Big Five and Cattell’s 16 personality factors?
16 traits can be grouped into 5 second order global factors which correlate with the big 5
strengths of cattell’s 16 personality factors?
revolutionary contribution using factor analysis and computer technology
lots of research supporting
weaknesses of cattell’s 16 personality factors?
findings not easy to replicate and realistically only 5 factors
different to Eyesenck as factors correlated with each other not independent
discuss the complication of subjective labelling of traits?
similar traits have been given different names by different theorists
have to look at meaning underlying a trait rather than just its name
who created the Big Five and when?
and what are they?
1987 McCrae & Costa Openness Conscientiousness Extraversion Agreeableness Neuroticism
name some similarities between Cattell & Eysenck?
emphasising biological and genetic factors
nomothetic approach
factor analysis (used in different ways)
explaining personality of normal adults
name some differences between Cattell & Eysenck?
cattell
- primary factors: source traits
- data driven - inductive
- oblique rotation - factors can be correlated with each other
Eysenck
- second-order factors - supertraits
- theory driven - deductive
- orthogonal rotation - factors not correlated as independent of each other
briefly describe Eysenck’s theory?
3 second-order factors called supertraits which contain large number of source or narrow traits - hierarchical structure (derived from intercorrelations between source traits)
genetically determined
focused on temperament
what are Eysenck’s 3 essential traits and what is the genetic cause of them?
PEN
Psychoticism - tendency towards psychotic behaviour
Extraversion - high extraversion = low level of cortical arousal
Neuroticism (vs emotional stability) - high neuroticism = excessive activitiy of sympathetic nervous system
example of the hierarchical structure of supertraits (Eysenck) - extraversion?
level 1: super-ordinate trait/second-order factors = extraversion
level 2: narrow/source traits = e.g sociable, dominant
level 3: habitual acts = regularly party going behaviour
level 4: specific acts = dancing on table
describe the extraversion - introversion super-ordinate trait?
balance of inhibition and excitation in the brain
Ascending Reticular Activating System (ARAS) in brainstem controls overall cortical arousal
extraverts - lower levels of activity in ARAS (lower cortical arousal) so seek contexts with high stimulation
introverts - higher levels of activity in ARAS so seek contexts with low stimulation
describe the neuroticism-emotional stability super-ordinate trait?
scoring high on neuroticisim scale doesn’t make you neurotic but might be more susceptible to neurotic problems
high neuroticism arises from hypersensitivity or excessive activity of sympathetic nervous system meaning react more to threatening environments
key neurotic symptom is the panic attack
what did Holeva & Tarrier (2001) find about the link between neuroticism and PTSD?
studied victims of road traffic accidents (4 weeks and 6 months after)
those scroing highly on neuroticism (and to a lesser extent psychoticism) were associated with the development of PTSD
so high trait anxiety appear to increase risk of developing PTSD
examples of studies findings links between neuroticism and psychological disorders?
Holeva & Tarrier 2001 - car accidents more likely to suffer PTSD when neurotic
Ormel & Wohlfarth 1991 - link between neuroticism and psychological distress in life changing situations
Clark, Watson & Mineka 1994 - link between neuroticism and mood/anxiety disorders
describe the psychoticism super-ordinate trait?
added later as a super-ordinate trait and less well researched
potential link to dopaminergic system
high scores on psychotic measures indicate recklessness, inappropriate emotional expression and manipulative
name some of the findings from the EPQ? (Eysenck Personality Questionnaire)
introverts tend to demonstrate superior academic performance in western and non-western cultures (Kline, 1966)
those with high E,N & P scores are more likely to engage in criminal activity (Eysenck, 1977)
what is meant by agreeableness, openness and conscientiousness in the Big Five?
openness - unconventional and indepedent thinker
conscientiousness - controlled and organised
agreeableness - helpful, trusting and sympathetic
how is the Big Five measured?
using the NEO-PI (Costa & McCrae, 1985)
each of the five super traits are measured by 6 subordinate traits e.g agreeableness - ruthless vs soft hearted
research supporting the big five and findings using it?
big five personality afctors have emerged in studies of school children and appear to be fairly stable over time (Soldz & Vaillant, 1999)
extraverts exercise and drink more
conscientiousness get better grades
openness more likely to play musical instrument
agreeable smoke less
findings regarding the big five and job performance?
Barrick & Mount, 1991
found conscientious showed consistent relations with all job performance cirteria
extraverts predicted success in management and sales
agreeableness and neuroticism predict performance when working in groups
findings regarding the big five and job satisfaction?
Judge, Heller & Mount, 2002
only relationships between neuroticism and extraversion and ob satisfaction generalised across studies
what are some of the problems with the big five?
can be reproduced cross-culturally but not always the same 5, nor are there always 5
women score consistently higher in N, A and C
fails to account for how authoritarian personalites treat people differently depending on their rank
what does Eysenck (3 essential traits) suggest about the big five and is there research supporting him?
suggests the big five mixes superfactors (extraversion and neuroticism) with primary traits (agreeableness and conscientiousness)
Draycott & Kline, 1995 analysed the NEO-PI and EPQ-R and found the big five mixes lower prder with higher order factions
describe the type theory to personality?
assumption that people are qualitatively different from each other
as focuses on patterns of traits that characterise people and sorts these patterns into types of people
aims to classify people into categories that are distinct - you are either one type or another
e.g either an introvert or an extravert not on a continuum (trait approach)
describe sheldon’s somatotypes?
- endomorph - sociable character with plump shape
- mesomorph - assertive with muscular shape
- ectomorph - fragile with poor muscles
describe the earliest personality theory and contemporary research related to this?
four humors of ancient greeks & medicine called humorism:
- excess blood = robust
- excess black bile = depresed
- ecess yellow bile = angry
- excess phlegm = cold
contemporary research = type A personality having chronic hostility raises risk of having heart attack
correspond with Eysenck’s 3 essential traits
describe the Jungen personality theory?
at least 2 different personality types of introversion (internally oriented) and extraversion (internally orientated)
recognised people never one category but incorporate aspects of both although one dominant in individual’s functioning
in the Jungen personality theory, what is meant by dominant and auxiliary functions?
recognised people never one category but incorporate aspects of both although one dominant in individual’s functioning
2 auxiliary functions within the dominant function-
1. perceiving information (via senses or intuition) 2. making decisions (objective logic or subjective feelings)
auxiliary functions are preferences, we can use both but we have a preference (innate but shaped by environment e.g family) for one over the other e.g senses over intuition
what are Jungen’s 8 personality types using the dominant and auxiliary functions?
extraverted & introverted sensing
extraverted & introverted intuition
extraverted & introverted thinking
extraverted & introverted feeling
how did Briggs and Myers develop Jungen’s typology?
added a forth auxiliarly function / preference
judging (ordered/structured enviro) vs perceiving (flexible/unstructured)
so 4 functions in jungen's extended theory: extraverted-introverted sensing-intuitive thinking-feeling judging-perceiving
describe the Myers-Briggs Type Indicator?
defines 16 personalit types
questionnaire widely used in business to assist employment decisions
evidence questions reliability and validity
existence of 16 types questioned
re-test data from 3 months later indicicates around 50% a different type
where are indidivual differences apparent in our health?
in attitudes that individuals have towards their health
describe the personality characteristics of type A individuals?
and the risks associated with this personality?
type a & b are extreme ends of the continuum with a being a syndrome of several traits
ongoing struggle to achieve more in less time and work longer hours
than Type B (non-coronary prone)
in competition with others
show more physiological responses to stress
suffer increased risk of heart disease, more driving accidents (Nabi et al., 2005) and sacrfifice relationships to strive for achievement (Carver & Humphries, 1982)
describe the personality characteristics of type B individuals?
relaxed
work hard sometimes but not driven in compulsive manner
less interested in competition and power
what are the 3 major traits identified by Glass, 1977 making up a Type A personality?
- easily aroused hostility (leads to 20% increased risk of CHD, Childa & Steptoe,2009) and most strongly implicated as risk factor)
- sense of time urgency
- competitive achievement strivings
why are there mixed findings when looking for alink between type a personality and coronary heart disease?
haynes et al, 1978 found predictor
cohen & reed, 1985 found no association
more likely to find association when using strctured interview compared to a questionnaire
what did Williams et al find in their large longitudinal study regarding anger (dimension of Type A personality) and heart disease?
studied nearly 13 000 middle aged adults
higher anger scores twice as likely to suffer from CHD
3x more likely to be hospitalised or die fro heart disease during study
what is the explanation why anger and hostility (dimension of Type A personality) are related to CHD?
may be due o unhealthy lifestyle (smoking, drinking, heavier), poor social support, weaker immune systems and enhanced cardiovascular reactivity to stress through sympathetic nervous system (most important)
what is the hormone theory about link between type a personality and CHD?
secrte excessive amounts of epinephrine and norepinephrine (adrenaline and noradrenaline)
play a part in constriction and dilation of blood vessels and has role in onset of heart problems
interventions therefore aim to reduce stress, anger and alter lifestyle patterns
what are other personality factors related to increased rsk of CHD?
- depression
- low levels of social support
- high hostility and anger (Type A)
what is meant by the type D personality?
explanation for link with CHD?
denollet, 2005
distressed personality type
combination of depression and social inhibition (isolated)
may be due to less likely to report symptoms to clinicians due to social inhibition (Schiffer et al, 2007)
describe Lombroso’s theory regarding the ‘criminal man’, 1876?
first attempt at investigating criminal personality
argued the shape of the head and face determined who was ‘born criminal’ and hence a separate species
this shape is atavistic meaning features related to our ancestors of primates e.g large jaw and ears
murderers: lots of hair, long ears and thin lips
sex offenders: strong jaw, thick lips and projecting ears
describe Sheldon’s theory, 1942, regarding somatotype and crime?
basis is that body shape is correlated with personality but not on person purely 1 somatotype:
ectomorph (small&thin): sensitive and introvert
endomorph(big): relaxed and extraverted
mesomorph(muscley): active and aggressive - characterised as criminals due to the traits they possess
what is a criticism of the basis of Sheldon’s somatotype theory?
developed the 3 body types based on a sample of 300 males
this leaves out over 50% of the population (women) who may not have the same body types and characteristics etc
also, although 80-90% of criminal population being men, 10-20% are women
describe Sheldon’s study regarding somatotypes and crime?
problems with this study?
looked through 200 student and 200 male delinquents body types
found delinquent population significantly more mesomorphic - appearing to support his theory
classification of somatotype in this study unreliable
didn’t use legal criteria to select delinquent sample and when re-analysed used legal critera to define delinquency, association no longer found
what are some alternative explanations regarding Sheldon’s theory on somatotype and crime?
and disputing evidence?
muscley people have learned from young age that best way to get what they want is to be aggressive
more likely to be recruited by gangs
British Crime Survey found smaller body types usually performing delinquent acts, perhaps due to rough background (hence why small) so driven to crime - more accurate as has much larger and wider sample
describe Eysenck’s personality theory regarding criminal behaviour?
3 factors influencing behaviour and each other in situations where criminal behaviour is a possible outcome:
social - responses to socialisation (reinforcement and punishment and anti-social behaviour curbed by conscience developing due to socialisation)
psychological - stable psychological traits (crucial role in process of socialisation) - may be more than his 3
biological - functioning of the nervous system (e.g hypersensitive autonomic nervous system implicated in neurotic individuals and physiological arousal in conditionability (high when N)-speed&efficiency of socialisation)
what may be an issue with Eysenck’s personality theory and crime regarding the samples he looked at?
he was more interested in looking at the ‘normal’ population so worked mainly with delinquents and those with ‘time limited criminality’ meaning perform minor crimes and grow out of that phase in 20s
therefore not studying true criminals so theory may not be relevant to those commiting more serious criminal acts or certain crimes
as shown by theory concerning development of anti-social behaviour not directly criminal behaviour (legal and social factors involved to become this)
how does Eysenck link extraversion and neuroticism to conditionability in personality theory and crime?
and the later added P?
conditionability - speed and efficiency of a child’s socialisation
stable introvert - low E and N most easy to condition
neurotic extravert - high E and N least easy so may turn to anti-social behaviour
low E and high N (&vice versa) mid-point in conditionability
high P related to offending particularly in hostile crimes towards others
what does evidence suggest about the link between Eysenck’s 3 personality traits and crime?
supports that high P and N predictors for criminals (Bartol & Bartol, 2005)
less clear for E but made up of sociability and impulsivity, the latter of which is found often in offenders but the first not related
what are some personality disorders linked with crime?
psychopathy
anti-social personality disorder
the dark triad - machiavellianism (manipulation and deception of others in pursuit of their goals), narcissism (excessive admiration of one’s self) and psychopathy
Big Five certain patterns of characteristics in criminal populations
