11 Personality - Psychology 2e

PERSONALITY

What is Personality?

  • Personality: The long-standing traits and patterns that propel individuals to consistently think, feel, and behave in specific ways.

    • Derived from the Latin word persona, meaning a mask worn by an actor, historically used to represent specific personality traits.

    • Descriptive characteristics include emotions such as happy, sad, impatient, shy, fearful, curious, and helpful.

Historical Perspectives

Hippocrates (370 BCE)

  • Theorized that personality traits and human behaviors emerge from four separate temperaments associated with bodily fluids.

    • Choleric: Associated with yellow bile; traits include being passionate, ambitious, and bold.

    • Melancholic: Associated with black bile; traits include being reserved, anxious, and unhappy.

    • Sanguine: Associated with red blood; traits are joyful, eager, and optimistic.

    • Phlegmatic: Associated with white phlegm; traits include being calm, reliable, and thoughtful.

  • Galen expanded on this theory to explain diseases and personality using these humors.

Phrenology

  • Franz Gall (1780): Proposed that bumps on the skull could reveal personality traits, character, and mental abilities; discredited due to lack of empirical support.

    • Developed a chart correlating specific skull areas with personality traits.

Immanuel Kant (18th Century)

  • Asserted categorization into four temperaments using traits to describe each temperament.

Wilhelm Wundt (19th Century)

  • Suggested that personality could be described using two major axes:

    1. Emotional/Non-emotional: Differentiates strong emotions (melancholic, choleric) from weak (phlegmatic, sanguine).

    2. Changeable/Unchangeable: Distinguishes changeable temperaments (choleric, sanguine) from unchangeable (melancholic, phlegmatic).

Psychodynamic Perspectives (20th Century)

Sigmund Freud

  • Developed the first comprehensive theory of personality, focusing on unconscious drives influenced by sex, aggression, and childhood sexuality.

  • Levels of Consciousness:

    • Unconscious: Mental activity that is hidden from awareness, affecting behavior.

    • Freudian Slip: Accidental verbal mistakes revealing unconscious urges.

The Id, Ego, and Superego

  • Id: Primitive urges focused on basic needs (hunger, thirst, sex), operates on the pleasure principle.

  • Superego: Internal moral compass, develops through social interactions, strives for perfection, creates feelings of pride or guilt.

  • Ego: Balances id and superego, operates on the reality principle, rational aspect of personality seen by others.

  • Effects on Personality:

    • Balanced interaction between id and superego leads to a healthy personality; imbalance leads to neurosis or unhealthy behaviors.

Defense Mechanisms

  • Unconscious behaviors aimed at reducing anxiety, used by the ego.

  • Overuse can be problematic.

Stages of Psychosexual Development

  • Freud outlined five stages wherein pleasure-seeking urges focus on different body parts:

    1. Oral Stage (Birth - 1 year): Erogenous zone - mouth; adult fixation may lead to smoking, overeating.

    2. Anal Stage (1-3 years): Erogenous zone - anus; issues can result in an anal-retentive or anal-expulsive personality.

    3. Phallic Stage (3-6 years): Desire for opposite-sex parent, includes Oedipus and Electra complexes; adult fixation leads to over-ambition or vanity.

    4. Latency Stage (6-12 years): Sexual feelings are dormant.

    5. Genital Stage (12+): Redirects sexual urges towards socially acceptable partners.

Contemporary Theories of Personality

Alfred Adler

  • Focused on individual psychology and the drive to compensate for feelings of inferiority, introducing the inferiority complex.

  • Emphasized social connections and posited that birth order influences personality.

    • Identified three social tasks:

    1. Occupational tasks (careers).

    2. Societal tasks (friendships).

    3. Love tasks (intimate relationships).

Erik Erikson

  • Developed a psychosocial theory presenting eight stages of development, emphasizing social relationships and their role in personality development over the lifespan.

Carl Jung

  • Contributed to analytical psychology, focusing on the balance of conscious and unconscious thought.

    • Introduced concepts of the collective unconscious and archetypes, asserting that these universal themes derive from shared human experiences.

  • Developed contrasting concepts of extroversion (energized by social interactions) and introversion (energized by solitude).

Karen Horney

  • Advocated for self-realization and corrected Freud's theory about envy.

  • Proposed coping styles in response to anxiety:

    1. Moving toward people: Dependency.

    2. Moving against people: Aggression.

    3. Moving away from people: Isolation.

Behavioral Perspective

B.F. Skinner
  • Focused on observable behaviors shaped by environmental reinforcements, asserting that personality develops continuously through experiences.

Social-Cognitive Perspective

Albert Bandura
  • Proposed that cognitive processes interact with behavior and the environment (reciprocal determinism) to shape personality, emphasizing observational learning and self-efficacy in a social context.

Julian Rotter

Locus of Control
  • Defined the locus of control as a belief system about control over life outcomes on a continuum from internal to external.

    • Internal locus of control: Belief outcomes result primarily from personal effort.

    • External locus of control: Belief outcomes are determined by external forces like luck.

Walter Mischel

The Person-Situation Debate
  • Found that behavior varies significantly across different situations, igniting debate on personality consistency over time and context.

  • Marshmallow Study: Examined self-regulation and willpower, revealing correlations with later life success and behavioral issues based on self-control levels.

Humanistic Approaches

Abraham Maslow

  • Studied self-actualized individuals, identifying shared qualities of creativity, compassion, and acceptance.

Carl Rogers

  • Linked personality with self-concept, differentiating between ideal self and real self.

    • Congruence: High degrees lead to self-worth and a productive life; low degrees lead to maladjustment.

Biological Approaches

Heritable Traits

Minnesota Study of Twins Reared Apart
  • Concluded that identical twins share strong similarities in personality regardless of upbringing, indicating significant genetic influence.

    • Traits with heritability over 0.50 include leadership and resilience.

Temperament

  • Observed early life temperaments categorized as easy, difficult, or slow to warm.

  • Important dimensions:

    1. Reactivity: Response to stimuli.

    2. Self-Regulation: Control over responses.

Somatotypes

William H. Sheldon
  • Proposed three body types linked to personality traits:

    1. Endomorphs: Relaxed and sociable.

    2. Mesomorphs: Adventurous and competitive.

    3. Ectomorphs: Anxious and thoughtful.

Trait Theorists

Gordon Allport

  • Classified personality traits into three categories:

    1. Cardinal Traits: Dominant traits (rare).

    2. Central Traits: Core characteristics.

    3. Secondary Traits: Context-dependent traits.

Raymond Cattell

  • Narrowed Allport's traits to 16 dimensions, measured on a continuum.

Hans & Sybil Eysenck

  • Proposed two primary personality dimensions:

    1. Extroversion/Introversion

    2. Neuroticism/Stability

Five Factor Model

Big Five Personality Traits

  • Each person has traits on a continuum forming the acronym OCEAN:

    1. Openness: Creativity and curiosity.

    2. Conscientiousness: Dependability and organization.

    3. Extroversion: Sociability and assertiveness.

    4. Agreeableness: Compassion and cooperativeness.

    5. Neuroticism: Emotional instability.

HEXACO Model

  • Consists of six personality traits described as follows:

    • (H) Honesty-humility: Sincerity, modesty.

    • (E) Emotionality: Sensitivity, sentimentality.

    • (X) Extraversion: Sociability and boldness.

    • (A) Agreeableness: Patience, gentleness.

    • (C) Conscientiousness: Organization, thoroughness.

    • (O) Openness: Creativity and inquisitiveness.

Cultural Understandings of Personality

Influence of Culture

  • Culture significantly impacts personality formation, with variations across different societies.

    • Examples:

    • Asian cultures exhibit collectivism, often leading to less extroversion.

    • Central and South American cultures score higher on openness.

    • Europeans tend to score higher on neuroticism.

Regional Differences in the U.S.

  • Identified personality clusters:

    • Upper Midwest and Deep South: Friendly and conventional.

    • West: Creative and emotionally stable.

    • Northeast: Stressed and irritable.

Individualist vs. Collectivist Cultures

  • Individualist Cultures: Emphasize independence and achievement; present in Western nations.

  • Collectivist Cultures: Prioritize social harmony and group needs; common in Asia, Africa, South America.

Assessment Methods

Self-Report Inventories

  • Commonly used tests in various fields including psychology, employment, and legal settings. They often utilize structured formats with multiple-choice or Likert scales.

Minnesota Multiphasic Personality Inventory (MMPI)
  • A widely utilized inventory with various scales for assessing psychological disorders, consisting of 338 items in its current version.

Likert Scales

  • Feature in many personality assessments, allowing respondents to express the degree of their agreement with statements.

Projective Tests

  • Projects unconscious feelings through interaction with ambiguous stimuli.

  • Major projective tests include:

    • Rorschach Inkblot Test: Interpretation of inkblot cards.

    • Thematic Apperception Test (TAT): Storytelling based on ambiguous images.

    • Rotter Incomplete Sentence Blank (RISB): Completing sentences to express unconscious desires and fears.

Examples of Test Questions

  • The questions utilized in tests such as the MMPI or RISB vary widely but often include statements prompting true/false responses or requiring complete sentences based on personal experiences or beliefs.
