Trait Models of Personality

What is Personality?

Personality refers to the unique patterns of thoughts, feelings, and behaviors that characterize an individual and persist over time and across situations.

• Definition: Enduring patterns of thinking, feeling, and acting.

• Examples: Outgoing, hardworking, shy, friendly, religious, calm, etc.

Clues About Personality

• Thoughts, beliefs, values: e.g., valuing friendships more than school.

• Feelings: e.g., feeling anxious before a test.

• Behaviors: e.g., being the life of a party.

Defining Personality

Personality is the set of psychological traits and mechanisms within the individual that are organized and relatively enduring, and that influence their interactions with, and adaptations to, the intrapsychic, physical, and social environments.

• Traits: The basic building blocks of personality.

• Consistency: The idea that people will behave similarly across situations.

Personality: Major Perspectives

• Trait/Dispositional theories

• Psychodynamic theories

• Humanistic theories

• Behavioral/social-cognitive theories

Why Measure Personality?

• To predict behavior

• To understand psychological problems

• To help in clinical, educational, and workplace settings

Trait Theories

• Trait: A relatively stable disposition to behave in a particular and consistent way.

• The trait approach uses terms to characterize differences among individuals by using language as descriptors.

Factor Analysis in Personality

Factor Analysis

Factor analysis is a statistical procedure used to identify clusters of related traits (factors) based on correlations among variables.

• Helps reduce a large number of traits to a smaller set of underlying factors.

• Example: Raymond Cattell identified 16 basic personality factors.

Measuring Personality

• Self-report inventories: Individuals answer questions about their characteristic behaviors.

• Projective tests: Individuals respond to ambiguous stimuli, revealing unconscious aspects of personality.

The Five-Factor Model of Personality (Big Five)

Big Five Traits

• Openness to Experience: Imagination, creativity, curiosity.

• Conscientiousness: Organization, dependability, discipline.

• Extraversion: Sociability, assertiveness, energy.

• Agreeableness: Compassion, cooperativeness, trust.

• Neuroticism: Emotional instability, anxiety, moodiness.

Mnemonic: OCEAN

Are the Big 5 Factors Universal?

• Research supports the universality of the Big Five across cultures, though some variations exist.

Walter Mischel: Person-Situation Consistency

• Argued that behavior is influenced more by the situation than by personality traits.

• Personality traits may not predict behavior as strongly as previously thought.

Free Will and Determinism

• Free will: The belief that people have the power to choose their own behaviors.

• Determinism: The belief that all events, including human actions, are determined by causes external to the will.

Behaviorist and Social-Cognitive Perspectives

Behaviorism

Behaviorism is a theoretical orientation based on the premise that scientific psychology should study only observable behavior.

• B.F. Skinner: Radical behaviorism; personality is fully determined by environmental stimuli.

• Personality is a collection of response tendencies that are tied to various stimulus situations.

Bandura: Social Learning Theory

• Emphasizes observational learning, environmental events, and behavior as influences on one another (reciprocal determinism).

Bandura: Observational Learning

• Key processes: Attention, Retention, Reproduction, Motivation.

Psychodynamic Perspective

Sigmund Freud

• Founder of psychoanalysis; emphasized the influence of the unconscious mind on behavior.

• Personality is shaped by unconscious motives and conflicts.

Levels of Consciousness

• Conscious: Thoughts and feelings we are aware of.

• Preconscious: Memories and thoughts not currently in awareness but easily retrieved.

• Unconscious: Thoughts, urges, and memories outside of conscious awareness.

Basic Instincts

• Life instincts (Eros): Drive for survival, reproduction, pleasure.

• Death instincts (Thanatos): Aggressive and destructive drives.

Structure of Personality (Freud)

• Id: Primitive, instinctual part of the mind; operates on the pleasure principle.

• Ego: Rational part; mediates between id and reality; operates on the reality principle.

• Superego: Moral standards and ideals; provides guidelines for making judgments.

Freud's Model of Personality Dynamics

• Conflict: Ongoing negotiation of opposing impulses (id, ego, superego).

• Anxiety: Results from conflicts among the id, ego, and superego.

Defense Mechanisms

• Repression: Keeping traumatic memories hidden in the unconscious.

• Denial: Refusing to accept reality.

• Displacement: Redirecting emotions to a substitute target.

• Projection: Attributing one's own unacceptable impulses to others.

• Rationalization: Creating logical explanations for behaviors.

• Reaction formation: Behaving in a way opposite to one's true feelings.

• Sublimation: Channeling impulses into socially acceptable activities.

Psychosexual Stages of Personality Development

• Oral stage: Pleasure centers on the mouth (birth to 1 year).

• Anal stage: Pleasure focuses on bowel and bladder control (1-3 years).

• Phallic stage: Pleasure zone is the genitals (3-6 years).

• Latency stage: Dormant sexual feelings (6 to puberty).

• Genital stage: Maturation of sexual interests (puberty onward).

Humanistic Perspective

Humanistic Psychology

• Emphasizes the unique qualities of humans, especially free will and the drive for personal growth.

• Focuses on realizing one's full potential.

Abraham Maslow (1908-1970)

• Proposed the hierarchy of needs, culminating in self-actualization.

Level	Description
Physiological	Basic needs: food, water, shelter, clothing, etc.
Safety	Security, health, employment, property, safety against threats
Love/Belonging	Friendship, intimacy, family, sense of connection
Esteem	Respect, self-esteem, status, recognition
Self-actualization	Achieving one's full potential, including creative activities

Self-Concept

• How a person views themselves (actual self) and how they would like to be (ideal self).

• Discrepancies between actual and ideal self can lead to anxiety and low self-esteem.

Development of the Self

• Children need unconditional positive regard to develop a healthy self-concept.

• Conditional love can lead to anxiety and defense mechanisms.

Summary Table: Major Personality Theories

Theory	Main Focus	Key Figures
Trait	Describing and measuring traits	Allport, Cattell, Eysenck, Costa & McCrae
Behaviorist	Learning and environment	Skinner, Bandura
Psychodynamic	Unconscious motives and conflicts	Freud, Jung, Adler
Humanistic	Personal growth and self-actualization	Maslow, Rogers
