Try to describe the characteristics of a person who is close to you. You will primarily name enduring characteristics (traits), which influence the life of that person in a particular way. Is the individual, for instance, extraverted, reserved or open for new experiences? The following terms are used in the context of personality characteristics in psychology:
- Traits: Enduring personality characteristics – personality is defined as the sum of all of these traits.
- Predisposition: The characteristics of an individual determine his behaviour.
- Consistency/stability over time: Personality characteristics persist over an extended period of time (months or years), i.e. carelessness vs. conscientiousness.
- Trans-situational consistency: Personality characteristics remain stable in various situations, i.e. unreliability at work as well as in relationships.
Other important terms are:
- Temperament: a biologically determined reaction mode relating to the level of activity. .
- State-Trait: persistent condition vs. momentary condition
The most important models of personality
The most recent and universally acknowledged model of personality is the Big Five Model (Five-factor model). Over the last two decades, it was used in approximately 3,000 scientific studies. In this Big Five model, you can recognize parts of other models of personality.
Eysencks 3 dimensions of personality (1953)
Even today, the two dimensions of personality, extraversion and neuroticism, appear in various questionnaires, whereas the third dimension assumed by Eysenck, psychoticism, has always been the focus of harsh criticism.
Extraversion and introversion
The two poles extraversion and introversion stand for the degree of sociability and personal exposure, as opposed to reservation and control.
|– open, sociable, impulsive– seeking excitement and change
– happy, carefree
– higher excitation threshold of the ascending reticular activating system ⇒ seeking external stimulation
|– calm, serious, reserved– seeking quiet and retreat
– observing, reliable
– lower excitation threshold ⇒ seeking quieter environments
People with high levels of neuroticism are emotionally unstable, overly sensitive, and often suffer from fear and anxiety. Frequently, associated psychosomatic complaints like headaches, restless sleep, gastrointestinal symptoms, etc. may occur. Other characteristics are: nervousness, insecurity, mood swings, vulnerability for negative emotions, impulsiveness.
People with low levels of neuroticism are rather well-adjusted and emotionally more stable. They can handle burdens and stress quite well and remain calm even in extreme situations. They rarely or never focus on negative feelings and self-doubt is rather unusual.
According to Eysenck, the third dimension of psychoticism comprises a range of realistic/normal to psychopathic/criminal to psychotic behaviour. People with a high level of psychoticism are unable to show empathy and are regarded as cold and unfriendly.
The Big Five: The Five-Factor Model
The founders of the Big Five assumed that personality is reflected in language. The focus was on the „lexical hypothesis“: All important aspects of human personalities are evident from the utilization of specific adjectives, in order to describe oneself or others. After extensive factor analysis of various dictionaries, adjectives proved to be alike across cultures.
The Study of Personality Over Decades Resulted in the Five Dimensions of Human Personality.
With the aid of these dimensions, all people can be compared and described. In the 1980s already characterized by Goldberg, they achieved general publicity through the standardized personality test NEO Personal Inventory (Neo Five-Factor Inventory).
What makes the Big Five model so special is that individuals are not classified into predefined categories, but rather that very individual personality profiles can be established on the basis of the five dimensions.
|Dimension||High level||Low level|
||cooperative, caring, helpful, compliant, kind||sceptical, competitive, critical, confronting|
||curious, non-conform, creative, interested||cautious, traditional, conservative, factual|
||casual, volatile, inconsistent, unreliable, messy||determined, organized, disciplined, orderly, pedantic, reliable|
||restrained, calm, quiet, solitary, reserved||active, social, talkative, cheerful, expressing positive emotions|
||well-adjusted, relaxed, carefree, calm||anxious, nervous, worried, emotionally unstable|
Tip for exams: Memorize the Big Five very well – for years they could be found among the IMPP questions every six months, time and again.
The interactionist approach
Despite individual personality characteristics, people behave differently depending on situation and environment. Do you behave the same way during a lecture, a doctor-patient conversation, at a party or among family? The current state of research assumes a dynamic interactionist approach: the environment and one’s personality mutually influence each other.
Interactionism = disposition (characteristic of a person) + situationism (environmental impacts)
The learning theory personality model
The behaviourist approach assumes that any behaviour is exclusively formed by environmental amplifiers. Every individual behaves in certain situations according to his or her life history of learning. Behavioural theorists focus especially on the possibility that learned behaviour can be changed systematically.
The psychodynamic model (Freud)
Freud’s approach especially concentrates on early childhood experiences. The different stages of psychosexual development which want to be coped with make for a great conflict potential. If a person fails in one stage of development, a fixation on this stage may occur (oral, narcissistic, anal, phallic, latent, and genital).
Where does “normal“ end and “abnormal“ begin? In the ICD-code (F60), personality disorders are listed under personality and behaviour disorders with the following description:
“These are severe personality and behaviour disorders of the individual not directly resulting from brain damage or disease or from any other psychiatric disorder. They involve different personality areas, and are almost always associated with personal and social impairment. Personality disorders usually manifest themselves during childhood or adolescence and continue into adulthood.“
Hardly any diagnosis is as difficult to make as the one for personality disorders. The following criteria have to be evaluated – yet always in the light of the current situation and social and cultural context of the person concerned:
- Emotional responsiveness
- Self control
- Social adaptation
- Ability to form relationships
Acquaint yourself with the following personality disorders in DSM IV and their main criteria:
- Paranoid: Distrust, hostility, always suspecting that others are deceiving them, expecting bad things in general, jealousy
- Schizoid: Loner, distant, difficulty with for social relationships, little empathy
- Schizotypal: Illusions, flat affect, fear of social relationships, eccentricities in behaviour and appearance
- Antisocial (also sociopathic or psychopathic): Aggressive, reckless, impulsive, emotionally decayed, unable to feel empathy
- Emotionally unstable: Borderline personality, extremely emotional, push-pull relationships, autoaggressive behaviour, unstable self-image, impulsive
- Histrionic: Excessive drama in one’s behaviour, attention seeking, flat affect, egocentric
- Narcissistic: Exaggerated sense of self-importance, extremely egoistic, excessive need for constant admiration and attention, lack of empathy, problems with social relationships
- Avoidant: Low self-esteem, feeling of incompetence and worthlessness, fears of rejection, being blamed or put down
- Dependent: Almost always follows others, no or little focus on one’s own needs, great fears of being alone and being left alone
- Obsessive-compulsive: Compulsive, constant preoccupation with planning and rules, (problems in social relationships), perfectionist, overly conscientious
Personal constructs and behavioral styles
Field dependence and field independence (cognitive style)
According to this construct, people differ according to their ability to identify an item in a context. The individuals are classified into “differentiated/analytic“ and “global“ according to the Embedded Figures Test.
In the Embedded Figures Test, individuals have to detect “embedded figures“ in a hidden context as fast as possible. Individuals who can differentiate the items well are described as being field independent.
Interference tendency describes the degree of susceptibility towards interference with respect to irrelevant stimuli: the level of cognitive control. A common method of measurement is the Stroop effect whereby individuals have to name the colour of a word without becoming distracted by the choice of the word (red, green, yellow, …). Hereby, the reaction time is measured.
This is an example for the Stroop effect:
Sensation seeking (Zuckerman, 1979)
Every personality is seeking a different level of stimulation. Zuckerman’s construct is very similar to Eysenck’s approach to extraversion/introversion. Sensation seeking means having a tendency to seek new, stimulating situations.
Thus, a risky, nonconformist behaviour with a propensity for extremes (i.e. extreme sports or excessive partying) is aimed for.
Sensation seeking is divided into four stages. How would you classify yourself?
- Thrill and adventure seeking: Physically risky activities
- Experience seeking: Change through an unconventional lifestyle (travelling, music, drugs)
- Disinhibition seeking: Change through social stimulations (party, promiscuity, social drinking)
- Boredom susceptibility: Aversion towards boredom and tendency to restlessness when the environment no longer offers change.
Special behavioral styles from the clinical area
The following constructs of personality are particularly important with regard to the relationship between personality and diseases, as well as respective coping styles.
Locus of control: Internal and external
In the concept of locus of control, you will recognize many similarities with the model of learned helplessness and the styles of attribution. Especially in the clinical field, locus of control plays an important role. Depending on whether the patient perceives the locus of control as internal or external, the process and genesis of the disease are formed.
- Internal locus of control: People with a strong internal locus of control rate the importance of their own behavior on events in their life as very high.
- External locus of control: People with a high external locus of control blame fate, other people and circumstances for the events in their life. There is not a lot of importance placed on one’s own influence.
Sensitization and Repression
This construct focuses on how people deal with fear evoking stimuli. Sensitizers confront these stimuli and place a stronger focus on their processing and origin. Repressors rather move these stimuli aside and repress facing their fears.
The passive resignation style is characterized by attributing failures internally. Individuals show lower levels of activity, respond more depressively and altogether behave with an “enduring“ attitude as their consistent basic attitude: “Everything is senseless anyway.” This behavioral style is based on the construct of learned helplessness by Seligman.
Behaviour classification into type A, type B and type C
Do certain personalities have a high risk for coronary heart diseases? The classification into Type A and B addresses this question. Originally developed in the 60s, the classification into types was very successful at first. However, a causal relationship between health critical behaviour and an actual coronary disease could not be proven.
The simplicity of the construct is another disadvantage. The additional development of Type C tries to detect personality characteristics which are associated with cancer diseases (empirically not confirmed!).
|Type A behaviour „Coronary-prone personality“||Type B behaviour||Type C behaviour „Cancer-prone personality“|
|Constant pressure to achieveHighly ambition, often exceeds one’s own energy limits
High need for control (little delegation)
|All people who don not display the type A behaviour. Seeking quiet and recoverySocial relationships are of high priority
Need for rest
|Denial of negative emotionsInability to express anger
Tendency towards depressive
Self-concept and self-esteem
We have assumptions and value judgements about ourselves which are relatively stable in a mentally healthy individual. This self-concept develops from social experiences in different areas (school, sports, university, social relationships, etc.) and is significantly shaped in childhood and adolescence. Many scientists divide this self-concept into two parts:
- Cognitive descriptive component (Example: „I master German grammar quite well.“)
- Emotional evaluative component (Example: „I am satisfied with my average grade in the extremely difficult exam.“)
