Theories of Personality: Comprehensive Study Notes

Theories of Personality

Introduction

This study guide summarizes major theories and perspectives on personality, as covered in Psychology 2035A. Personality psychology explores the enduring patterns of thoughts, feelings, and behaviors that make each individual unique. Understanding these theories provides insight into human motivation, development, and behavior.

The Nature of Personality

Defining Personality and Traits

Personality is defined as an individual's unique constellation of consistent behavioral traits. A personality trait is a durable disposition to behave in a particular way across various situations.

• Common personality traits include honesty, moodiness, impulsiveness, and friendliness.

• Traits are relatively stable over time and across contexts.

The Five-Factor Model (Big Five)

Paul Costa and Robert McCrae identified five higher-order traits that are widely accepted in contemporary personality research:

• Extraversion: Sociability, assertiveness, and positive emotions.

• Neuroticism: Emotional instability, anxiety, and moodiness.

• Openness to Experience: Imagination, creativity, and curiosity.

• Agreeableness: Compassion, cooperativeness, and trust.

• Conscientiousness: Organization, dependability, and discipline.

Additional info: The Big Five model is supported by cross-cultural research and is used in many psychological assessments.

Psychodynamic Perspectives

Overview of Psychodynamic Theories

Psychodynamic theories, originating from Sigmund Freud, emphasize unconscious mental forces and internal conflicts as determinants of personality.

• Personality is shaped by unconscious motives and childhood experiences.

• Key theorists: Sigmund Freud, Anna Freud, Melanie Klein, Alfred Adler, Carl Jung, and object relations theorists.

Freud's Psychoanalytic Theory

Freud proposed that personality consists of three components:

• Id: The primitive, instinctive component operating on the pleasure principle.

• Ego: The decision-making component operating on the reality principle.

• Superego: The moral component incorporating societal standards of right and wrong.

These components interact across three levels of awareness:

• Conscious: Thoughts and feelings we are aware of.

• Preconscious: Material just beneath the surface, easily retrievable.

• Unconscious: Deep, inaccessible thoughts and memories influencing behavior.

Defense Mechanisms

Defense mechanisms are unconscious strategies used to protect the self from anxiety and distress.

Mechanism	Definition	Example
Repression	Keeping distressing thoughts buried in the unconscious	A traumatized person has no recollection of a close brush with death.
Projection	Attributing one's own feelings to another person	A woman who dislikes her boss thinks her boss dislikes her.
Displacement	Diverting emotions to a substitute target	After a scolding, a child takes anger out on a sibling.
Reaction Formation	Behaving in a way opposite to one's true feelings	A parent who resents a child spoils them with gifts.
Regression	Reverting to immature patterns of behavior	An adult has a temper tantrum when frustrated.
Rationalization	Creating plausible excuses for unacceptable behavior	A student watches TV instead of studying, claiming extra study wouldn't help.
Identification	Bolstering self-esteem by forming alliances	An insecure young man joins a fraternity to boost self-esteem.

Additional info: Excessive reliance on defense mechanisms is linked to mental health impairments.

Jung's Analytical Psychology

Carl Jung expanded on Freud's ideas, proposing two layers of the unconscious:

• Personal Unconscious: Similar to Freud's concept, containing personal experiences.

• Collective Unconscious: A shared storehouse of ancestral memory traces, containing archetypes (universal symbols and ideas).

Archetypes manifest in dreams, art, and cultural symbols.

Evaluation of Psychodynamic Theories

• Contributions: Highlighted unconscious influences, childhood experiences, and defense mechanisms.

• Criticisms: Lack of testability, reliance on case studies, and potential bias (e.g., gender and cultural).

Behavioral Perspectives

Behaviorism and Personality

Behaviorism focuses on observable behavior and the influence of environmental stimuli.

• Personality is seen as a collection of learned response tendencies.

• Key processes: Classical conditioning, operant conditioning, and observational learning.

Classical Conditioning

Classical conditioning is a type of learning where a neutral stimulus acquires the capacity to evoke a response originally elicited by another stimulus.

• Explains acquisition of emotional responses (e.g., phobias, anxiety).

• Extinction: The gradual weakening and disappearance of a conditioned response.

Operant Conditioning (B.F. Skinner)

Operant conditioning involves learning through consequences of voluntary behavior.

• Behaviors followed by favorable outcomes are strengthened.

• Behaviors followed by unfavorable outcomes are weakened.

Type	Definition	Example
Positive Reinforcement	Response strengthened by arrival of pleasant stimulus	Receiving praise for good work.
Negative Reinforcement	Response strengthened by removal of unpleasant stimulus	Turning off a loud alarm by getting out of bed.
Punishment	Response weakened by arrival of unpleasant stimulus	Receiving a scolding for misbehavior.

Bandura's Social Cognitive Theory

Bandura emphasized observational learning and the role of self-efficacy (belief in one's ability to achieve desired outcomes).

• Learning occurs by observing models and the consequences of their actions.

• High self-efficacy leads to confidence and persistence; low self-efficacy leads to doubt.

Evaluation of Behavioral Perspectives

• Strengths: Empirical research base, explanation for moderate consistency in behavior.

• Limitations: Over-reliance on animal research, less focus on actual behavior in modern theories.

Humanistic Perspectives

Overview of Humanistic Theory

Humanistic theories emphasize the unique qualities of humans, free will, and the drive for personal growth.

• Humans are conscious, rational beings capable of personal growth.

• Key theorists: Carl Rogers, Abraham Maslow.

Rogers's Person-Centered Theory

Rogers proposed that personality is based on the self-concept—a collection of beliefs about one's nature and behavior.

• Congruence: Self-concept matches actual experience.

• Incongruence: Self-concept does not match reality, leading to anxiety and psychological distress.

• Unconditional positive regard from parents fosters congruent self-concept; conditional affection leads to incongruence.

Maslow's Theory of Self-Actualization

Maslow described a hierarchy of needs, culminating in self-actualization—the realization of one's potential.

• Hierarchy (from lowest to highest): Physiological, safety, love/belonging, esteem, cognitive, self-actualization.

• Self-actualizing individuals are open, spontaneous, appreciative, and enjoy peak experiences.

Evaluation of Humanistic Perspectives

• Contributions: Emphasized self-concept and psychological health; foundation for positive psychology.

• Criticisms: Lack of testability, idealistic view of human nature, limited empirical evidence.

Contemporary Empirical Approaches

Narcissism

Narcissism is a personality trait marked by a sense of self-importance, need for attention, and entitlement.

• Research shows narcissists have fragile self-concepts and seek to maintain self-esteem.

• Levels of narcissism have increased in recent generations.

• Types: Grandiose and vulnerable narcissism.

Terror Management Theory (TMT)

TMT posits that awareness of mortality creates anxiety, which is buffered by cultural worldviews and self-esteem.

• Mortality salience increases self-esteem as an anxiety buffer.

• Provides a sense of order and meaning.

Culture and Personality

Individualism vs. Collectivism

Personality is influenced by cultural values:

• Individualism: Prioritizing personal goals and attributes over group membership.

• Collectivism: Prioritizing group goals and identity within the group.

Self-enhancement (focusing on strengths and positive feedback) is more common in individualistic cultures.

Self-Insight and Cultural Differences

Research suggests collectivism may promote greater self-insight than individualism, especially regarding socially desirable behaviors.

• Holier than thou phenomenon: Tendency to overestimate one's likelihood of engaging in desirable behaviors compared to peers.
