Comprehensive Personality Psychology Notes

Psychodynamic Perspective on Personality


Psychodynamic Perspective

Freud's Psychoanalytic Theory


Sigmund Freud
  • Core Premise: Unconscious processes originating in early childhood determine much of human personality (Prescribed reading: Morris, 2017, pp. 481–491).

  • The Topography of the Mind:

    • The mind operates across three levels of awareness:

      • Conscious: Thoughts, perceptions, and feelings that are currently in awareness.

      • Preconscious: Memories, knowledge, and information that can be easily brought into conscious awareness.

      • Unconscious: Reservoir of drives, urges, repressed desires, and memories outside of conscious awareness.

    • Unconscious impulses leak out through Freudian slips (slips of the tongue), jokes, dreams, and accidental behaviors.


Topography of the mind
  • Basic Drives:

    • Human motivation is driven by two fundamental biological drives:

      1. Sex (Eros / Libido).

      2. Aggression (Thanatos / Aggressive drive).

  • Psychosexual Stages of Personality Development:

    • Oral Stage (0−18 months0-18\text{ months}):

      • Primary Focus: Mouth (sucking, biting, swallowing).

      • Conflicts and Concerns: Dependency on caregivers.

    • Anal Stage (2−3 years2-3\text{ years}):

      • Primary Focus: Bowel and bladder elimination.

      • Conflicts and Concerns: Orderliness, cleanliness, control, and compliance.

    • Phallic Stage (4−6 years4-6\text{ years}):

      • Primary Focus: Genitals.

      • Conflicts and Concerns: Identification with parents and resolution of the Oedipus complex.

    • Latency Stage (7−11 years7-11\text{ years}):

      • Primary Focus: Dormant sexual interest.

      • Conflicts and Concerns: Sexual and aggressive impulses are channelled into socially acceptable activities (academics, sports, hobbies).

    • Genital Stage (12+ years12+\text{ years}):

      • Primary Focus: Mature sexual interests.

      • Conflicts and Concerns: Development of mature sexuality, romantic relationships, and social integration.

  • Fixations:

    • Definition: Conflicts or concerns that persist beyond the developmental stage in which they arise, caused by either undergratification or overindulgence at that stage.

    • Example: An oral fixation in adulthood may manifest as smoking, excessive eating, drinking, or nail-biting.

  • Structure of Personality:

    • Id:

      • Level of Thought: Unconscious.

      • Operating Principle: Pleasure Principle (demands immediate gratification of biological urges).

      • Description: Houses simple biological needs and instinctual drives.

    • Ego:

      • Level of Thought: Largely conscious.

      • Operating Principle: Reality Principle (delays gratification until appropriate outlets are available).

      • Description: Acts as the mediator among the demands of the id, the standards of the superego, and external reality.

    • Superego:

      • Level of Thought: Largely unconscious.

      • Operating Principle: Idealistic Principle.

      • Description: Comprises the moral conscience and internalised societal and parental standards.

  • Defence Mechanisms:

    • Definition: Unconscious mental strategies used by the ego to prevent unacceptable thoughts or impulses from reaching conscious awareness, thereby protecting the mind from distress or anxiety.

    • Repression: Excluding sources of anxiety completely from conscious awareness.

    • Projection: Attributing one's own unacceptable qualities, impulses, or thoughts to someone else.

    • Reaction Formation: Warding off an uncomfortable or unacceptable thought by actively emphasizing its exact opposite.

    • Rationalisation: Concocting a seemingly logical, acceptable reason or excuse for shameful or improper behaviour.

    • Displacement: Shifting emotional reactions or impulses from the original target object to a safer surrogate object.

    • Sublimation: Channelling socially unacceptable impulses into productive, socially acceptable, or admirable behaviours.

  • Contributions and Limitations of Freud's Theory:

    • Limitations: Questions regarding scientific testability and falsifiability ("It may be fascinating – but is it science?"); presence of significant cultural and sexist biases (e.g., male-centric perspectives).

    • Contributions: Highlighted the crucial role of childhood experiences, early parental relationships, and unconscious mental processes in shaping adult personality.

Neo-Freudian Psychodynamic Approaches

  • Theoretical Shifts from Freud:

    • Place less emphasis on instinctual sexual and aggressive drives.

    • Place greater emphasis on social interactions and interpersonal relationships.

    • Place less emphasis on the unconscious mind and greater emphasis on ego function and development.

  • Karen Horney's Theory:

    • Countered Freud's concept of "penis envy" by proposing that men experience "womb envy" due to their inability to bear children.

    • Focused on social interactions as the primary driver and source of adult personality and behaviour.

    • Identified parental indifference as "the basic evil" that engenders basic anxiety in children.

    • Neurotic Coping Styles: Children growing up in environments that are "not safe" develop a dominant, neurotic style to cope with basic anxiety:

      1. Compliant: Moving toward people; strives to be sweet, self-sacrificing, and saintly.

      2. Aggressive: Moving against people; strives to be powerful, recognised, and a winner.

      3. Detached: Moving away from people; strives to be independent, aloof, and perfect.

Humanistic, Social Cognitive, and Biological Perspectives

Humanistic Perspective

  • Prescribed reading: Morris (2017), pp. 491–498.

  • Core Focus: Concentrates on an individual's phenomenological reality (subjective experience of the world), inherent human goodness, and the striving for personal growth and self-actualisation.

  • Carl Rogers' Self Theory:

    • Self-concept is central to personality development.

    • The core determinant of psychological health is the congruence between the real self (who a person actually is) and the ideal self (who a person wants to be).

    • Development of the Self:

      • Humans possess a universal need for positive regard.

      • Receiving conditional positive regard leads to self-discrepancies and incongruence.

      • Receiving unconditional positive regard fosters self-actualisation.


Development of the Self Model
  • The Fully Functioning Person: A child raised with unconditional positive regard develops into a fully functioning person characterized by:

    1. Openness to experience.

    2. Existential living (living fully in each moment).

    3. Organismic trusting (trusting one's inner feelings and judgments).

    4. Experiential freedom (feeling free to choose one's direction).

    5. Creativity.

  • Contributions and Limitations of Humanism:

    • Contributions: Unique focus on how humans search for and construct meaning in life.

    • Limitations: Fails to provide a comprehensive theory of personality; concepts are vague and difficult to operationalise; lacks strong empirical research support; criticized as overly idealistic.

Social Cognitive Perspective

  • Core Premise: Explains individual differences in personality through learned beliefs, expectancies, cognitive interpretations, and social situations.

  • Expectancies:

    • The expectation of whether a specific behavior will yield reinforcement exerts a powerful influence on thoughts, feelings, actions, and personality traits.

  • Locus of Control (Julian Rotter):

    • Internal Locus of Control: Belief that outcomes are determined by one's own actions, efforts, and choices ("You make things happen").

    • External Locus of Control: Belief that outcomes are governed by external factors, luck, chance, or fate ("Things happen to you").


Locus of Control
  • Self-Efficacy (Albert Bandura):

    • Definition: An individual's beliefs concerning their ability to execute the specific behaviors required to achieve desired outcomes or goals.

    • Impact: Influences motivation, level of perseverance when facing obstacles, locus of control, and self-confidence.

    • Sources of Self-Efficacy:

      1. Performance experiences (past mastery or failures).

      2. Observational learning (vicarious experience through modeling).

      3. Verbal persuasion (encouragement or feedback from others).

      4. Emotional arousal (physiological and anxiety states).

  • Reciprocal Determinism (Bandura):

    • Personality is produced by a continuous, three-way interaction among:

      1. Personal factors (e.g., self-efficacy, cognitive beliefs).

      2. Behaviour (e.g., performance, actions).

      3. Environment (e.g., teacher feedback, social environment).


Reciprocal Determinism Model
  • Contributions and Limitations:

    • Contributions: Highly testable and supported by extensive empirical research evidence.

    • Limitations: Underemphasises personality processes that operate outside conscious awareness.

Biological Perspective (Part 1: Neurophysiology & Temperament Systems)

  • Eysenck's Theory:

    • Personality traits are directly linked to specific neurophysiological mechanisms in the brain.

    • Eysenck Personality Minitest Scoring Rules:

      • Extraversion: Count "yes" responses to questions 1, 4, 8, 11, and 13. A score of ≥3\ge 3 indicates extraversion.

      • Neuroticism: Count "yes" responses to questions 3, 6, 10, 12, and 15. A score of ≥3\ge 3 indicates neuroticism.

    • Neurophysiological Mechanism: Differences between extraverts and introverts stem from genetically determined differences in baseline arousal within the central nervous system (CNS). Introverts have high baseline CNS arousal and avoid overstimulation, whereas extraverts have low baseline arousal and seek stimulus-rich environments.

  • Reinforcement Sensitivity Theory (Jeffrey Gray):

    • Behavioural Activation System (BAS): Brain structures that motivate approach behaviour toward reward stimuli ("Go system"). Extraverts possess a stronger BAS, making them more sensitive to and easily influenced by rewards.

    • Behavioural Inhibition System (BIS): Brain structures sensitive to punishment stimuli that inhibit behaviour leading to danger or pain ("Stop system"). Introverts possess a more active BIS, making them more sensitive to and easily influenced by punishment.

Behavioural Genetics and Developmental Aspects of Personality

Biological Perspective (Part 2: Behavioural Genetics & Temperament)

  • Prescribed reading: Morris (2017), pp. 503–505.

  • Behavioural Genetics:

    • Goal: Establish the proportion of behavioral variation attributable to heredity.

    • Heritability: The proportion of variance in a specific trait across a population due to genetic influences.

    • Twin Studies:

      • Comparisons of Monozygotic (MZ / identical) and Dizygotic (DZ / fraternal) twins (including those separated at birth) show that approximately 40−50%40-50\% of the variation in Big Five personality traits is inherited.

      • Shared family environment exerts only a small effect on personality traits.

      • Nonshared environment (an individual's unique, unshared experiences) exerts a much larger effect.

      • Parenting Role: Family environments contain nonshared aspects (e.g., unique child-parent dynamics), and caregivers significantly impact development outside broad trait inheritance.

    • Polygenic Influence: Personality traits are polygenic, shaped by complex interactions among multiple genes and environmental inputs.

  • Temperament:

    • Definition: Innate, biologically-based tendencies to feel or act in specific ways from infancy.

    • Three Dimensions of Temperament (Buss & Plomin, 1984):

      1. Activity level (overall energy and vigor of movement).

      2. Emotionality (intensity of emotional reactions).

      3. Sociability (tendency to affiliate with others).

    • Shyness and Inhibition (Jerome Kagan):

      • Inhibited infants react to novel situations with startle responses and emotional distress.

      • Inhibition measured at 4 months4\text{ months} predicts shyness in childhood and adolescence.

      • Biological Basis: The amygdala is more easily aroused and reactive in inhibited children.


Amygdala location in brain
  • Social Component: Shyness involves an interaction between biological vulnerability and social experiences.

  • Contributions and Limitations of Biological Perspective:

    • Contributions: Firmly demonstrated that human personality has a substantial genetic foundation.

    • Limitations: Heritability coefficients risk oversimplifying trait etiology; genes and environment dynamically interact in every trait.

Nature, Nurture, and Comparative Contexts

  • Prescribed reading: Swartz et al. (2021), Ch. 5.

  • Animal Personality:

    • Spotted Hyena Study (Gosling, 1998): Documented 5 personality traits in spotted hyenas (though not identical to human traits).

    • Cross-Species Evidence (Gosling & John, 1999): Confirmed that traits corresponding to extraversion, neuroticism, and agreeableness exist in most animal species.

    • Openness to Experience: Displayed in animals as individual differences in curiosity and playfulness.

    • Conscientiousness: Only chimpanzees showed evidence of conscientiousness among tested non-human animals.

    • Rationale: Animal personality research provides insights into genetic, biological, and environmental determinants of personality, aids understanding of perception processes, and informs animal welfare strategies.

  • Age and Personality Development:

    • Transition to Personality: Parents reliably identify Big Five traits in children by age 33. Early temperament links to later adult traits, but full stability is not reached until middle childhood or later.

    • Adult Personality Trajectories:

      • Maturity Principle: Across cultures, agreeableness, conscientiousness, and emotional stability increase systematically from adolescence through middle age.

      • Individual Rank-Order Stability: Relative rankings on Big Five traits remain enduring, with rank-order stability increasing with age.

      • Drivers of Stability: Genetic factors, early experiences, and stable environmental contexts.

      • Drivers of Change: Biological maturation, environmental transitions, and poor person-environment fit.

  • Gender and Personality:

    • Empirical Trends:

      • Women average higher scores on traits emphasizing social connectedness, empathy, nurturing, and neuroticism.

      • Men average higher scores on traits emphasizing autonomy, individuality, anger, and physical aggression.

    • Explanations: Biological mechanisms (e.g., testosterone, natural selection) vs Sociocultural mechanisms (e.g., social roles).

    • Caveat: Individual personality differences within each gender are far greater than average differences observed between genders.

  • Culture and Personality:

    • Cultural Bias: Traditional theories emphasize Euro-American values of individuality and autonomy, which may not translate across non-Western cultures.

    • Cross-Cultural Trait Differences:

      • Collectivist Cultures: Higher average scores on agreeableness; higher external locus of control.

      • Individualistic Cultures: Higher average scores on extraversion and openness to experience; higher internal locus of control.

    • Explanations for Cultural Differences: Genetically influenced temperamental distributions, test response style biases, and child socialisation aligned with cultural values.

  • Personality and Adjustment (Fit):

    • Optimal adjustment depends heavily on person-environment fit across the lifespan.

    • Career Application — Holland's Model: Classifies personalities and occupations into 6 types (RIASEC): Realistic, Investigative, Artistic, Social, Enterprising, Conventional.


Holland's RIASEC Personality Hexagon
  • Critique in South Africa (SA): Holland's model rests on assumptions invalid in developing contexts like SA (assumes employment is freely available, educational opportunities are equal, and career selection is an unconstrained individual choice).

Personality Assessment and Behavioral Correlates

Methodological Approaches to Assessment

  • Prescribed reading: Morris (2017), pp. 513–520.

  • Idiographic Approaches:

    • Person-centred approaches focusing on individual lives and the unique integration of personal characteristics.

    • Examples: Psychobiography, detailed clinical interviews, narrative case studies.

  • Nomothetic Approaches:

    • Variable-centred approaches focusing on universal characteristics common to all people, evaluating individual variations along standardized scales.

    • Examples: Standardized questionnaires, self-report inventories.

Personality Assessment Instruments

  • Projective Measures:

    • Mechanism: Assess unconscious processes and motives by presenting ambiguous stimuli and evaluating unstructured responses.

    • Rorschach Inkblot Test: Interpretation of symmetrical inkblots.


Rorschach inkblot sample
  • Thematic Apperception Test (TAT): Construction of stories around ambiguous picture scenes.


Thematic Apperception Test card
  • Evaluation: The reliability and validity of projective tests are questionable and widely criticized.


Reliability and Validity diagram
  • Objective Measures:

    • Mechanism: Structured and standardized personality assessments using self-reports or informant ratings.

    • Prominent Instruments:

      • 16 Personality Factor Questionnaire (16PF).

      • Minnesota Multiphasic Personality Inventory, version 2 (MMPI-2).

      • Revised Neuroticism/Extraversion/Openness Personality Inventory (NEO-PI-R / NEO-PI-3).

      • South African Personality Inventory (SAPI).

    • Evaluation:

      • Strengths: Easy to administer; standardized scoring enables comparisons across individuals.

      • Limitations: Subject to response biases (acquiescence, social desirability); potential test item bias; reference group effect (lacking objective external standards for self-rating); can be dehumanising.

Music Preferences as a Window into Personality

  • Four Dimensions of Music Genre Preference (Rentfrow & Gosling, 2003):

    1. Reflective and Complex (Classical, Blues, Jazz, Folk):

      • Correlated Traits: High Openness to Experience (inventive, imaginative, intelligent, tolerant, politically liberal).

    2. Intense and Rebellious (Rock, Alternative, Heavy Metal):

      • Correlated Traits: High Openness to Experience (curious, intelligent, physically active, risk-taking).

    3. Upbeat and Conventional (Country, Pop, Soundtracks, Religious music):

      • Correlated Traits: High Extraversion, High Agreeableness, High Conscientiousness; Low Openness to Experience (cheerful, outgoing, reliable, helpful, physically attractive, conventional).

    4. Energetic and Rhythmic (Rap/Hip-Hop, Soul/Funk, Electronic/Dance):

      • Correlated Traits: High Extraversion, High Agreeableness (talkative, energetic, physically attractive, forgiving, politically liberal).

  • Accuracy of Music-Based Judgments:

    • Rentfrow & Gosling (2006): Observers listening to an individual's top 10 songs accurately judged Openness to Experience, Extraversion, Emotional Stability, and Agreeableness (though failed to accurately judge Conscientiousness).

    • Nave et al. (2018): Online study (n=22 252n = 22\,252) demonstrated that reactions to short, unfamiliar musical excerpts predicted individual differences in Openness and Extraversion beyond age and gender variables.

  • Theoretical Explanations for Musical Correlates:

    1. Activity Congruence: People select music that complements activities they enjoy.

    2. Emotion Regulation: People select music that reinforces or regulates their emotional states.

    3. Self-Identity Motives: People select music that reinforces self-perceptions and signals social identity to others.

  • Overall Conclusion on Assessment: Every assessment method has distinct strengths and weaknesses; utilizing a diversity of idiographic and nomothetic approaches provides a comprehensive understanding of human personality.
