Chapter 8: Personality – Foundations, Perspectives, and Measurement

Personality: Definition and Core Questions

What is Personality?

Personality is a complex concept in psychology, referring to the reliable patterns of thinking, feeling, and behaving that characterize an individual. Each psychological theory offers its own definition, but most agree that personality is a stable set of traits and tendencies that influence how people interact with the world.

• Reliable pattern: Personality is consistent across time and situations.

• P (Person) variable: Used in psychological models to represent individual differences.

Three Essential Questions

• What is personality? (Structure: organization and elements)

• How does personality work? (Function: purpose and role in behavior)

• Where does personality come from? (Origin: biological, psychological, and social sources)

Fundamental Assumptions in Personality Psychology

Key Dimensions

Personality theories often address several fundamental assumptions:

• Choice: Free Will vs. Determinism (Is behavior chosen or determined by forces outside our control?)

• Source: Nature vs. Nurture (Are traits inherited or shaped by environment?)

• Universality: Is everyone basically the same, or are there meaningful differences?

• Change: Can personality change over time?

Goals of Personality Psychology

Major Objectives

Personality psychology seeks to:

• Describe: Identify and classify personality traits and patterns.

• Explain: Understand the causes and mechanisms underlying personality.

• Predict: Forecast future behavior based on personality traits.

• Change: Explore possibilities for modifying personality or its expression.

Socio-Historical Perspectives on Personality

Philosophical and Religious Views

• Philosophy: Plato’s dualism (body and psyche) – the mind and body as separate entities.

• Religions:

  • Sufism (Islamic perspective)

  • Zen Buddhism (focus on abandoning self)

  • Judeo-Christian perspectives

• Abandoning self: Seen as a way to achieve health and reduce suffering in some traditions.

The Trait Perspective

Overview

The trait perspective aims to define the minimum core characteristics (traits) that can describe all personalities. Traits are considered stable, inherited features that influence behavior.

• Determinism: Personality is determined by traits; little room for free choice.

• Nature: Traits are inherited, representing inner forces.

• Stability: People are basically the same and remain stable over their lifespan.

Five Factor Theory (Big Five)

Factor analysis has identified five major dimensions of personality, known as the Big Five:

• Openness to Experience

• Conscientiousness

• Extraversion

• Agreeableness

• Neuroticism

Each trait exists on a continuum from low to high.

Trait	Low Scores	High Scores
Openness	Down-to-earth, conventional	Imaginative, creative
Conscientiousness	Negligent, lazy	Detail-oriented, reliable
Extraversion	Quiet, reserved	Talkative, outgoing
Agreeableness	Critical, suspicious	Trusting, cooperative
Neuroticism	Calm, unemotional	Worried, temperamental

Measuring Personality

• Behavioral observations: Watching how people act in various situations.

• Self-report questionnaires: Individuals rate themselves on various traits (e.g., Big Five Inventory).

• Objective tests: Standardized measures such as the NEO Personality Inventory (NEO-PI), which assesses Neuroticism, Extraversion, and Openness.

The Psychodynamic Perspective

Overview

The psychodynamic perspective, most famously associated with Freud and Jung, posits that personality is shaped by hidden forces in the mind, especially unconscious motives and conflicts.

• Determinism: Personality is determined by unconscious processes; no free will.

• Nature over nurture: Biological drives are primary.

• Stability: Personality is stable and cannot be changed.

Freud: Levels of Consciousness

• Conscious level: What you are aware of.

• Preconscious level: Information below awareness but easily accessible.

• Unconscious level: Deep, inaccessible drives and memories that most influence behavior.

Freud: Contents of the Unconscious

• Eros: Life drive, creation, libido (sexual impulses).

• Thanatos: Death drive, destruction.

Freud: Structure of the Mind

• Id ("It"): Pleasure principle – "If it feels good, do it." Seeks immediate gratification.

• Ego ("I"): Reality principle – mediates between id and superego, seeks safety and realistic solutions.

• Superego ("Over-I"): Idealistic principle – internalized ideals and conscience, "Do the Right Thing."

Freud: Psychic Conflict

• Occurs when the id, ego, and superego have incompatible urges, resulting in anxiety.

• The ego acts as the executive mediator.

• Defense mechanisms: Strategies used by the ego to protect the self from anxiety generated by psychic conflict.

Freud: Defense Mechanisms

• Denial: Refusing to believe something is a problem (e.g., denying substance abuse).

• Repression: Unconsciously pushing anxiety-inducing thoughts out of awareness.

• Regression: Reverting to childlike behaviors when stressed.

• Reaction formation: Acting in the opposite way to an anxiety-producing impulse.

• Displacement: Redirecting feelings to a safer target (e.g., yelling at a roommate instead of an instructor).

• Projection: Attributing one’s own unacceptable thoughts to others.

• Sublimation: Channeling unacceptable impulses into socially acceptable activities (e.g., exercise).

Freud: Psychosexual Development

• Oral stage (birth to 18 months): Oral fixation.

• Anal stage (18 to 36 months): Anal retentive traits.

• Phallic stage (3 to 6 years): Gender identity formation.

• Latency stage (7 to sexual puberty): Dormant sexual feelings.

• Genital stage (puberty to adulthood): Mature sexual interests.

Freud: How to Observe the Unseen

• Psychoanalysis: Talk therapy to reveal unconscious motivations.

• Free association: Saying whatever comes to mind.

• Dream analysis: Interpreting symbolic meanings in dreams.

• Parapraxis: Accidental leakage of unconscious thoughts into behavior (Freudian slips).

Projection Hypothesis and Projective Tests

• If a person is presented with an ambiguous stimulus, their personality will be projected onto it.

• Rorschach Inkblot Test: Interpretation of ambiguous inkblots.

• Thematic Apperception Test (TAT): Analysis of stories told about ambiguous pictures.

Jung's Contributions

• Agreed with Freud that unconscious motives drive personality.

• Disagreed with Freud’s emphasis on sexuality as the primary human motivation.

• Collective unconscious: Shared, inborn set of ideas and memories inherited at birth.

• Archetypes: Universal, shared concepts (e.g., "hero") often expressed in art and culture.
