Personality Psychology

Introduction to Personality Psychology

  • Personality is defined as a person's relatively consistent pattern of thinking, feeling, and behaving.
  • Characteristics of Personality:
    • Long-lasting patterns.
    • Research questions include:
    • What are the basic ways in which we differ?
    • How does personality develop over time?
    • How do biology and experience influence personality?

Psychoanalytic Perspective by Sigmund Freud

  • Sigmund Freud proposed that personality is determined by unconscious drives influencing our interactions with the world.
  • Major Contributions of Freud:
    • Development of the concept of the unconscious mind.
    • Identification of psychosexual stages of development.
    • Exploration of defense mechanisms used to alleviate anxiety.

Personality Structure

  • Personality is composed of three components:

    1. Id:
    • Operates on the Pleasure Principle, seeking immediate gratification and avoiding pain.
    • Contains basic desires (survival, reproduction, aggression) and is entirely unconscious.
    1. Ego:
    • Functions in reality; enables us to balance the id's desires with the supeego's ideals.
    • Follows the Reality Principle, satisfying the id’s desires in realistic and appropriate ways.
    1. Superego:
    • Acts as our conscience; represents idealistic standards and moral values influenced by society and parental guidance.

  • The majority of personality operates unconsciously.

Defense Mechanisms

  • Anxiety arises when the ego fails to mediate between the id and the superego.
  • Types of Defense Mechanisms include:
    • Denial: Refusing to acknowledge unpleasant aspects (e.g., an addict).
    • Rationalization: Making excuses for behavior (e.g., blaming others).
    • Reaction Formation: Converting an emotion into its opposite (e.g., overconfidence).
    • Projection: Attributing personal impulses to others (e.g., distrust in a partner).

Psychosexual Stages of Development

  1. Oral Stage (0-18 months):
    • Centered on eating and dependence.
    • Potential fixations include dependency issues based on early feeding experiences.
  2. Anal Stage (18-36 months):
    • Focus on control through potty training.
    • Fixations can result in disorganized or overly controlled personalities.
  3. Phallic Stage (3-6 years):
    • Involves jealousy and self-touching; Oedipus complex emerges.
    • Fixations relate to power obsessions or sexual jealousy.
  4. Latency Stage (6-11 years):
    • Sexual impulses are subdued and focus shifts to social and academic achievements.
  5. Genital Stage (12 years - adulthood):
    • Individuals focus on mature sexual relationships and adult personality development.

Criticisms of Freud's Theory

  • Notable criticisms include:
    • Too reliant on parental influence, disregarding other factors.
    • Issues with gender identity claims.
    • Psychosexual stages difficult to test empirically.
    • Some contributions remain relevant, such as the idea of the unconscious mind.

Trait Theories

  • Gordon Allport defined personality as a collection of traits, or continuous dimensions indicative of thought patterns and behaviors.
  • Traits are better predictors of behavior than types (e.g., Myers-Briggs).
  • The Lexical Hypothesis posits that key personality differences get encoded in language; research has identified 5 broad trait categories.

The Big Five Personality Traits

  • OCEAN Model:
    • Openness: Receptiveness to new ideas; traits range from imaginative to conventional.
    • Conscientiousness: Degree of discipline & organization; ranges from organized to careless.
    • Extraversion: Preference for social interaction; ranges from outgoing to reserved.
    • Agreeableness: Trust and concern for others; ranges from cooperative to critical.
    • Neuroticism: Emotional stability; ranges from emotionally stable to anxious.
  • The Big Five traits are relatively stable throughout life and predict important life outcomes like relationships and career success.

Self-Esteem

  • Self-esteem is the assessment of one's own worth, and is informed by perceived social value.
  • According to Sociometer Theory, self-esteem fluctuates based on social inclusion/exclusion.
  • Trait self-esteem influences dependency regulation, where high self-esteem increases connection and low self-esteem leads to self-protection.

Heritability of Personality

  • Investigates the genetic and environmental factors contributing to personality traits.
  • Heritability refers to the percentage of variation among individuals due to genetics, ranging from 0 (environmental) to 1 (genetic).
  • Research involving twins shows identical twins exhibit higher similarity in traits than fraternal twins.

Gene-Environment Interactions

  • Discusses how genetic makeup can influence responses to environments, thereby creating correlated similarities.
  • The impact of environment on expression of personality traits can vary significantly.

Personality and Neuroscience

  • Explores how biological systems, such as the Reticular Activating System (RAS), can influence behaviors like introversion and extraversion.

Person-Situation Debate

  • Examines the variability in behavior based on context versus the stability of personality traits.
  • Person-situation interactions suggest predictable behavior adapts to situations.

Measuring Personality

  • Various methods to assess personality include:
    • Self-Report: Individuals evaluate their own traits but may be prone to bias.
    • Informant-Report: Others assess an individual’s traits, which can reduce bias but lacks insight into internal perceptions.
    • Observation: Direct behavioral observation can provide objectivity but risks misinterpretation.
    • Biographical/Archival Data: Utilizing existing records offers insights but may lack depth in causal relationships.
