Personality Psychology

The scientific study of how and why people differ from one another, focusing on understanding the whole person and individual differences.

Personality

Patterns of thoughts, feelings, and behaviors, and the psychological mechanisms behind them.

The Psychological Triad

The three core components of personality: thoughts (beliefs, values, expectations), feelings (emotions and emotional experiences), and behaviors (observable actions).

Trait Approach

A theoretical approach to personality that focuses on enduring, comparative individual differences in personality characteristics.

Biological Approach

A theoretical approach that examines genetic and biological influences on personality, including hormones and neurotransmitters.

Psychodynamic Approach

A theoretical approach investigating underlying psychological processes, particularly unconscious influences.

Phenomenological Approach

A theoretical approach emphasizing subjective experiences and how individuals interpret their world.

Learning Approach

A theoretical approach focusing on learned responses, conditioning, and environmental influences on personality.

Population

The broader group of individuals that researchers want to understand and generalize their findings toward.

Independent Variable

The factor manipulated by researchers in an experimental study.

Dependent Variable

The measured outcome in an experimental study that may be affected by the independent variable.

Ecological Validity

The degree to which experimental designs, manipulations, and findings reflect real-world relevance and conditions.

Observational Studies

The most common research design in personality psychology, examining naturally occurring relationships without manipulating variables.

Cross-Sectional Studies

Observational research designs that measure variables across participants at a single point in time.

Longitudinal Studies

Research designs that repeatedly measure the same participants over an extended period of time to assess stability, change, and temporal ordering.

Case Studies

Intensive examinations of a single individual, providing rich detail and understanding of the whole person, especially useful for rare phenomena.

Behavioral Data (B Data)

Direct observations of an individual's actions in real-world contexts, standardized laboratory situations, or through projective techniques and nonverbal cues.

Electronically Activated Recorder (EAR)

An acoustic recording device that samples ambient sounds from individuals' everyday environments to collect objective behavioral data.

Life Outcome Data (L Data)

Objective and verifiable information about real-world events and outcomes in an individual's life, such as school, health, divorce, or criminal records.

Multidetermination

A disadvantage of life outcome data where an outcome results from multiple causes rather than a single personality trait.

Informant-Report Data (I Data)

Personality descriptions and judgments provided by knowledgeable informants who know an individual, such as parents, friends, partners, or coworkers.

Self-Report Data (S Data)

Personality descriptions provided directly by individuals assessing their own internal thoughts, feelings, and behaviors.

Funder's Second Law

The principle stating that there are no perfect indicators of personality; every data-gathering method possesses distinct strengths and limitations.

Replicability

The degree to which the findings of a study can be obtained again when the research is repeated.

Generalizability

The degree to which research findings apply across different populations, settings, and contexts.

Physiognomy

A nonscientific assessment method attempting to infer personality traits from physical appearance, particularly facial features.

Phrenology

A nonscientific assessment method attempting to infer personality characteristics from the shape and bumps of the skull.

Barnum Effect

The psychological tendency for individuals to interpret vague, highly generalized personality descriptions as personally meaningful or uniquely accurate.

Transparent Items

Assessment items where the specific psychological characteristic or trait being evaluated is relatively obvious to the respondent.

Nontransparent Items

Assessment items where the psychological characteristic or trait being evaluated is less obvious to the respondent.

Reliability

The consistency of a measurement instrument, demonstrated when it produces similar results under similar conditions.

Validity

The degree to which a measurement instrument actually assesses the specific theoretical construct it is intended to measure.

Face Validity

The degree to which an assessment instrument appears on the surface to measure the construct it is designed to evaluate.

Predictive Validity

The degree to which scores on a personality measure successfully forecast relevant future outcomes or behaviors.

Structural Validity

The extent to which the internal organization and statistical relations of a test match its proposed theoretical structure.

Convergent Validity

The degree to which a measure corresponds with other measures evaluating the same or related constructs.

Discriminant Validity

The degree to which a measure remains empirical and conceptually distinct from measures of unrelated constructs.

Constructivism

A philosophical position arguing that personality is socially constructed, thereby challenging the existence of an independent objective criterion for accuracy.

Critical Realism

A philosophical perspective holding that while no criterion is perfect, multiple imperfect pieces of information can be evaluated together to determine the accuracy of personality judgments.

Interjudge Agreement

A criterion for accuracy measured by the degree of consensus among different observers evaluating the same individual.

Attributional Complexity

A cognitive characteristic of good personality judges involving the tendency to recognize that behavior has multiple, complex explanations.

Judgability

The degree to which an individual's personality characteristics can be easily and accurately perceived and assessed by others.

Lexical Approach

A strategy for trait taxonomy construction based on the idea that the most important individual differences become encoded into natural language over time.

Openness to Experience

A Big Five personality trait characterized by curiosity, creativity, intellectual interest, and aesthetic sensitivity.

Conscientiousness

A Big Five personality trait characterized by organization, responsibility, dependability, punctuality, and productivity.

Extraversion

A Big Five personality trait characterized by being outgoing, talkative, sociable, assertive, and energetic.

Agreeableness

A Big Five personality trait characterized by warmth, kindness, cooperation, trust, and empathy.

Neuroticism

A Big Five personality trait characterized by anxiety, irritability, moodiness, tension, and emotional reactivity; its opposite pole is emotional stability.

Person-Situation Debate

The historical controversy over whether stable individual personality traits or external situational factors better predict and explain human behavior.

Situationism

A perspective emphasizing that external situations, environments, and social pressures are the primary determinants of behavior, minimizing the importance of internal personality traits.

Interactionism

A perspective associated with Kurt Lewin stating that behavior is determined by the continuous interplay between person-level dispositions and situational contexts.

Temperament

Early, partially biologically based individual differences in thoughts, feelings, and behaviors that represent the foundational roots of personality in infancy and childhood.

Negative Emotionality

A core temperament dimension characterized by fear, frustration, depression, and aggression, closely related to adult neuroticism.

Positive Emotionality

A core temperament dimension characterized by affiliation, positive affect, high-intensity pleasure, and perceptual sensitivity, related to extraversion.

Effortful Control

A core temperament dimension encompassing inhibitory control, activation control, and attention control, closely related to adult conscientiousness.

Rank-Order Stability

The consistency of an individual's relative ranking or position on a personality trait compared to other individuals over time.

Cumulative Continuity Principle

The developmental principle stating that the rank-order stability of personality traits generally increases as individuals grow older.

Mean-Level Change

The average degree and direction of increase or decrease in a personality trait across a group or population as age increases.

Social Investment Theory

A theoretical framework proposing that adopting adult social roles and responsibilities (such as careers, marriage, and parenthood) acts as a catalyst for personality development and change.

Maturity Principle

The developmental principle stating that people generally become better equipped to handle life's demands with age, typically showing average increases in responsibility, cooperation, and emotional stability.
