Comprehensive Notes on Personality Psychology

Defining Personality and the Scope of Personality Psychology

Personality is defined as the enduring patterns of thought, feeling, motivation, and behaviour that are expressed across different circumstances. It involves individual differences in characteristic patterns of how people think, feel, and behave across various contexts. This includes external social patterns and the internal processes that underpin how a person generally acts (Hogan & Bickle, $2014$).

Personality psychologists generally focus on two primary aims:

• Constructing theories that describe the structure of personality, which is the organisation of enduring patterns of thought, feeling, motivation, and behaviour.

• Studying individual differences, specifically the ways people differ from one another.

Individual differences research provides a framework for studying variable behaviours a person performs over time and in different situations, considering the person and various person-world interactions. People are multidimensional; therefore, it is unlikely that any one factor accounts for complex behaviours (O’Connor, $2008$). Personality lies at the intersection of virtually all psychological processes—cognition, emotion, and behaviour—occurring through their interplay. Throughout the study of personality, two central questions remain:

• What are the basic elements of personality (the distinct psychological 'fingerprint')?

• How stable is personality over time and across situations?

Psychodynamic Theories of Personality

Sigmund Freud developed the first comprehensive theory of personality. As a neurologist in the $1880s$, Freud encountered patients with hysteria—disorders involving paralysis or fainting with no apparent biological origin. Influenced by Jean-Martin Charcot, who used hypnosis to alleviate such symptoms, Freud reasoned that if a symptom is not physiological and the patient cannot consciously stop it, there must be an unconscious counter-will of equal or greater magnitude.

Freud’s theory of psychodynamics suggests psychological forces (wishes, fears, intentions) have direction and intensity. When motives collide, the balance of forces determines behaviour.

Carl Jung, a Swiss psychiatrist, initially influenced Freud before their friendship ended. Jung is known for:

• The collective unconscious: Structures of the unconscious mind common to all humans.

• Personality archetypes: Universal images or patterns in the collective and personal unconscious.

• Introversion and Extroversion: The two major personality factors.

• The Myers-Briggs Type Indicator (MBTI) is based on Jung’s work.

Freud’s Models: Topographic and Drive Models

Freud’s topographic model ($1900/1965$) used a spatial metaphor of the mind split into sectors:

• Conscious: Rational, goal-directed thoughts at the centre of awareness.

• Preconscious: Mental processes not currently conscious but which could become conscious at any point.

• Unconscious: Irrational processes organised along associative lines rather than logic. Access is barred by repression to avoid emotional distress.

In dreams, Freud distinguished between the manifest content (story line) and latent content (underlying message). Unconscious processes may 'leak' into consciousness through slips of the tongue.

Freud’s drive (instinct) model, influenced by Charles Darwin, hypothesised that humans are motivated by drives like other animals. He proposed two basic drives:

• Sexual drive (Libido): Broadly refers to pleasure-seeking, sensuality, and love, not just intercourse.

• Aggressive drive: Expressed in acceptable (sports, video games) and unacceptable ways.

Conflict, Ambivalence, and Compromise Formations

Freud emphasized ambivalence—conflicting feelings or motives. Research by Emmons and King ($1988$) asked participants to list $15$ personal 'strivings'. They found that higher conflict among strivings linked to more anxiety, depression, physical complaints (headaches, coughing, acne), and more health service visits. Kelly et al. ($2011$) found the highest depression rates in individuals with high ambivalence around goals and low levels of conflict among competing motives.

Compromise formations are solutions developed to maximise fulfilment of conflicting motives simultaneously. For example, people compromise between seeing themselves accurately and maintaining self-esteem, often creating a distorted self-portrait (Swann, $1997$; Kunda, $1990$).

Freud’s Developmental Model: Psychosexual Stages

Freud proposed that personality development follows a series of psychosexual stages defined by the focus of the libido on particular erogenous zones. Difficulties at any stage can lead to fixations (conflicts persisting beyond the period) or regression (reverting to earlier modes of emotion management).

• Oral Stage ($0$ to $18$ months): Exploration through the mouth. Difficulties lead to dependency or behaviours like thumb sucking and nail biting.

• Anal Stage ($2$ to $3$ years): Focus on toilet training, compliance, and defiance. Anal fixations may result in excessive orderliness/punctuality or extreme messiness/stubbornness.

• Phallic Stage ($4$ to $6$ years): Awareness of biological sex. Children identify with the same-sex parent. Identification involves internalising motives, beliefs, and ideals.

  • Oedipus Complex: Boys desire an exclusive relationship with their mother and fear castration by their father (castration complex).

  • Electra Complex: The female counterpart where girls transfer love to their father.

• Latency Stage ($7$ to $11$ years): Repression of sexual impulses; channelling energy into school and sports.

• Genital Stage ($12$ years and beyond): Conscious sexuality resurfaces; goal is mature sexuality and adult responsibilities.

Freud’s Structural Model

Freud’s final model described conflict among three mental forces:

• Id: Reservoir of sexual and aggressive energy; driven by the pleasure principle (immediate satisfaction) and primary process thinking (illogical, wishful).

• Superego: Conscience and source of ideals; the parental voice established through identification.

• Ego: Balances the id, superego, and external reality; operates on the reality principle and secondary process thinking (rational, logical).

Defence Mechanisms

Defence mechanisms are unconscious processes aimed at protecting a person from unpleasant emotions (anxiety) or bolstering pleasurable ones:

• Repression: Keeping threatening thoughts/memories from awareness.

• Denial: Refusal to acknowledge external realities (e.g., concluding a skin growth is 'nothing').

• Projection: Attributing one's own unacknowledged feelings/impulses to others.

• Reaction Formation: Overemphasising the opposite of unacceptable impulses.

• Sublimation: Converting impulses into socially acceptable activities.

• Rationalisation: Explaining away actions logically to avoid guilt or shame.

• Displacement: Directing emotions away from the real target to a substitute (e.g., hitting a punching bag).

• Regression: Reverting to an earlier developmental stage under stress.

• Passive Aggression: Indirect expression of anger (e.g., 'sitting on' important documents).

Analytical Psychology (Jungian Psychology)

Jung proposed the psyche is a self-regulating system maintaining balance between opposites. Key components include:

• The Ego: The conscious mind and identity.

• The Self: The central principle providing meaning and purpose. The goal is individuation (discovering uniqueness).

• Collective Unconscious: Universal memories/impulses from our ancestral past.

• Personal Unconscious: Repressed aspects of personality not congruent with morals/culture.

• Archetypes: Internal patterns including the Shadow (negative aspects from society), Anima (man's image of a woman), and Animus (woman's image of a man).

• Persona: Aspects of personality revealed or hidden from others.

• Psychological Types: Extroverted (energised by the external world) and Introverted (internal world).

Object Relations and Post-Freudian Developments

Object relations theories focus on interpersonal disturbances and the mental processes underlying relatedness. Humans are born seeking relationships. Representations of the self and significant others are crucial. People with relationship difficulties often expect malevolence (Buchele & Rutin, $2017$) and have trouble with constancy—keeping positive representations in mind during conflict (Kernberg, $1984$).

Relational theories argue human adaptation is primarily adaptation to others. For example, children exposed to psychologically controlling parents (love-withdrawal, possessiveness) express more social aggression/bullying toward peers (Kokkinos & Voulgaridou, $2017$).

Assessing Personality: Life History and Projective Tests

• Life History Methods: Qualitative in-depth case studies study the person in context.

• Projective Tests: Ambiguous stimuli where people 'project' meaning, revealing personality traits.

  • Rorschach Inkblot Test ($1921$): Participants describe what inkblots resemble.

  • Thematic Apperception Test (TAT): Participants make up stories for ambiguous drawings. Borderline personality disorder patients often display themes of abuse and egocentrism.

• Criticisms of Projective Tests: Lack of reliability/validity, influenced by investigator bias, and less useful in predicting behaviour than demographic data ($Garb, 1984$). However, they can assess implicit processes and disturbances in thinking.

Cognitive-Social Theories

Developed in the $1960s$, these theories (Social Learning Theory, Social-Cognitive Theory) emphasize that personality consists of learned behaviours and information processing. Albert Bandura ($1986, 1999$) argued people aren't just shaped by stimuli but by schemas, expectations, and goals.

Conditions for behaviour (Bandura’s Model): $1.$ Encoding: Categorising the event as relevant. $2.$ Personal Value: Relevance of the event for current goals or 'life tasks'. $3.$ Behaviour-Outcome Expectancy: Belief that a behaviour leads to a specific outcome. $4.$ Self-Efficacy Expectancy: Conviction in one's ability to execute a behaviour. $5.$ Competences: Skills required for performance. $6.$ Self-Regulation: Setting goals, monitoring progress, and adjusting.

A study by Wood and Bandura ($1989$) found that participants told ability was an 'acquirable skill' increased self-efficacy and performance, while the 'fixed-ability' group showed declines in all measures.

Trait Theories

Traits are emotional, cognitive, and behavioural tendencies on which individuals vary. Gordon Allport ($1937$) distinguished between observed traits and inferred dispositions.

Key Trait Theorists:

• Raymond Cattell ($1957$): Used factor analysis to identify $16$ key traits. Concluded $1/3$ of traits are determined by heredity and $2/3$ by environment.

• Hans Eysenck ($1953$): Identified three super-traits:

  • Extroversion-Introversion: Linked to cortical arousal via the ascending reticular activating system (ARAS). Introverts have higher resting ARAS levels and avoid stimulation.

  • Neuroticism-Emotional Stability: Linked to negative affect.

  • Psychoticism-Impulse Control: Aggressive, antisocial vs. empathic tendencies.

• Jeffrey Gray’s Reinforcement Sensitivity Theory (RST):

  • Behavioural Approach System (BAS): Attuned to rewards; extroverts have stronger BAS.

  • Behavioural Inhibition System (BIS): Attuned to punishment; introverts have stronger BIS.

The Five-Factor Model (FFM) and HEXACO

The FFM (OCEAN) is the most widely accepted model:

• Openness to experience: Intellectual curiosity, aesthetics.

• Conscientiousness: Discipline, organisation.

• Extroversion: Sociability, activity.

• Agreeableness: Trust, altruism.

• Neuroticism: Anxiety, impulsivity.

Cross-cultural studies (Schmitt et al., $2007$, with $17,837$ participants) confirm the FFM's robustness. The HEXACO model (Ashton & Lee, 2007) adds a sixth factor: Honesty-Humility, involving sincerity and greed avoidance.

Consistency and Stability of Personality

Walter Mischel triggered a debate in $1968$ arguing situation variables determine behaviour, showing test correlations of only $+0.30$ to $+0.40$. Seymour Epstein ($1979$) responded with the Principle of Aggregation, averaging behaviours across situations.

Stability across the lifespan:

• Inhibition to the unfamiliar (Kagan, $1989$): An aspect of temperament seen as early as $4$ months; predicts social anxiety in later years.

• Dunedin Longitudinal Study: Infants classified as 'difficult' at age $3$ were more likely to have alcohol problems or antisocial disorder at age $21$.

• Australian Temperament Project (ATP): Documentation of Victorian children since $1983$ shows temperament is relatively stable; 'difficult' infant characteristics increase emotional adjustment risks.

• Mischel’s If-Then Patterns: Personality lies in stable ways situations trigger specific patterns (e.g., aggressive if threatened).

Humanistic and Existential Theories

Humanistic psychology focuses on uniquely human aspects like meaning and being true to oneself.

• Carl Rogers (Person-Centred Approach): Focuses on phenomenal experience (conception of reality).

  • True Self: Core being untainted by others.

  • False Self: A mask worn to meet conditions of worth (standards set by others).

  • Ideal Self vs. Self-Concept: Divergence leads to distortion.

  • Actualising Tendency: Primary motivation to fulfil all human needs.

• Existentialism (Jean-Paul Sartre): Humans have no fixed nature (essence) and are free to alter their course.

  • Existential Dread: Recognition that life has no absolute value/meaning and death is inevitable.

  • Mortality Salience: Experiments show that thinking about death (e.g., questionnaires) makes people more punitive or more charitable as a buffer against anxiety.

Genetics, Personality, and Culture

Heritability refers to the proportion of variance in traits due to genetics. Twin studies indicate heritability estimates between $15$ percent and $50$ percent. The Minnesota study found MZ twins reared apart averaged $+0.50$ correlation on personality traits, similar to MZ twins reared together ($+0.51$).

Cultural Perspectives:

• Culture Pattern Approach: Culture shapes individuals to fit its organised beliefs and rituals (Benedict, $1934$).

• Interactionist Approach: Multidirectional causality; personality, economics, and culture mutually influence one another.

• Aboriginal Dreaming: Personality is linked to ancestral spirits and the spiritual whole of land, animals, and people.

Questions & Discussion

• How might projective tests help athletes? Qualitative techniques can provide deeper understanding of traits affecting performance that self-report questionnaires might miss.

• Are we responsible for actions? If behaviour is motivated by unconscious forces, the degree of accountability for war criminals or individuals in court remains a debated ethical/philosophical issue.

• Is character a specific or global trait? Considering Lance Armstrong’s behaviour, personality psychologists explore if a person can be honourable in one domain and dishonourable in another.

• How many traits are necessary? While FFM suggests $5$, Cattell suggested $16$, and Eysenck suggested $3$.
