Personality: Definition and Measurement
- Personality: The characteristic style of an individual’s behavior, thinking, and feeling.
- Four Main Approaches to Personality:
- Trait-Biological
- Psychodynamic
- Humanistic-Existential
- Social-Cognitive
- Study of Personality: Focuses on the variations in psychological differences among individuals.
Measuring Personality
- Personality Inventories:
- Rely on self-reporting via multiple-choice or forced-choice questions.
- Self-Report: Individuals answer a questionnaire indicating how well statements describe their behavior.
- MMPI-2-RF: A well-researched clinical questionnaire assessing personality and psychological problems, utilizing actuarial methods.
Projective Techniques
- Projective Techniques: Analyze ambiguous stimuli to elicit unique responses reflecting one’s personality.
- Thematic Apperception Test (TAT): Respondents create stories about ambiguous images, revealing underlying motives and social perceptions.
Trait Approach
- Trait Approach: Categorizes individual differences using trait terms.
- Challenges:
- Narrowing down endless adjectives.
- Understanding biological/hereditary foundations for particular traits.
- Traits: Defined as stable dispositions to behave consistently in particular ways (Gordon Allport, 1937).
Core Traits Exploration
- Core Traits:
- Early research indicated personality traits could be described via adjectives.
- Factor Analysis: Sorts personality components into small dimensions, questioning how many core traits exist.
- Big Five Personality Traits:
- OCEAN or CANOE model:
- Openness
- Conscientiousness
- Extraversion
- Agreeableness
- Neuroticism
- Criteria for reliability across cultures and minimal overlap.
Biological Basis of Traits
- Personality Influencers:
- Changes can result from brain damage, pathologies (e.g., Alzheimer's), or pharmaceutical treatments.
- Behavioral Genetics: Investigates genetic correlations in monozygotic vs. dizygotic twins, revealing personality traits affected by genetic and environmental factors:
- Heritability estimates:
- Openness: 0.41
- Conscientiousness: 0.31
- Extraversion: 0.36
- Agreeableness: 0.35
- Neuroticism: 0.37
Gender Differences in Personality
- Research indicates systematic personality differences, suggesting influences of culture and sex hormones:
- Women: More verbally expressive, sensitive to cues, nurturing, relationally aggressive.
- Men: More physically aggressive, assertive, slightly higher self-esteem.
- Controversial debate about the origins of these differences—biological versus cultural.
Psychodynamic Approach: Id, Ego, Superego
- Origin: Developed by Sigmund Freud, posits personality formed by unconscious needs and motives.
- Id: Instinctual drives.
- Ego: Reality principle, mediator.
- Superego: Moral compass.
- Anxiety arises from conflicts between these components.
- Defense Mechanisms:
- Unconscious strategies to reduce anxiety from unacceptable impulses, including:
- Rationalization
- Projection
- Sublimation
- Reaction Formation
Psychosexual Stages of Personality Development
- Sigmund Freud's stages of personality formation based on sexual gratification zones:
- Oral Stage: Focus on mouth; feeding and sucking.
- Anal Stage: Focus on bowel control; toilet training.
- Phallic Stage: Awareness of gender differences; coping with incestuous feelings.
- Latency Stage: Development of social and intellectual skills.
- Genital Stage: Mature adult personality development.
Humanistic-Existential Approach
- Focuses on healthy choices shaping personality.
- Self-Actualization: Realizing one’s inner potential, influenced by environmental factors.
- Flow Experience: Achieving focus when tasks align with abilities, as described by Mihaly Csikszentmihalyi.
Social-Cognitive Approach
- Views personality through thoughts about situations encountered in daily life, emphasizing perception of the environment.
- Personal Constructs: Dimensions used to interpret experiences, highlighting perspective differences crucial in personality.
- Locus of Control:
- Internal: Believing one controls their fate.
- External: Believing fate is controlled by external factors.
Self-Concept
- Self-Concept: Knowledge of one’s behaviors and traits; intertwined with personal narratives.
- Self-Schemas: Traits defining oneself, crucial in memory and self-conceptualization.
- Formation influenced by feedback from for relationships and environment.
Self-Esteem
- Defined as the extent to which one values and accepts themselves.
- Influenced by social perceptions, self-evaluations, and standards.
- Implicit Egotism: Preferring objects or people with similarities to oneself (e.g., name-letter effect).
Conclusion
- The study of personality encompasses various approaches that explore the complex interactions between biological, psychological, social, and cultural factors to understand individual differences in behavior, emotion, and thought.
