Chapter 1: Introduction to Personality Theories

Vocabulary flashcards covering fundamental concepts, criteria of scientific theories, measurement methods, and research strategies from Chapter 1: Introduction to Personality Theories.

Personality

The underlying causes within the person of individual behavior and experience.

Nomothetic approach

A research approach focused on comparing people and identifying patterns across groups, such as comparing test scores among many individuals.

Idiographic approach

A research approach focused on understanding one individual in depth, such as through a detailed case study.

Personality dynamics

The study of how personality operates and functions, addressing questions about adaptation and adjustment, cognitive processes, and culture.

Personality development

The study of how biological influences and experiences in childhood and adulthood contribute to personality formation and change across the lifespan.

Scientific method

A systematic approach and method of knowing based on observation and empirical evidence rather than opinions, assumptions, or intuition.

Determinism

The assumption that phenomena have causes that can be discovered through empirical research.

Theory

A conceptual tool for understanding specific phenomena by organizing ideas to help explain what happens and why.

Hypothesis

A specific, testable prediction derived from a theory that can be investigated through research.

Verifiability

A criterion of a good theory stating that it must make claims and predictions that can be tested and potentially supported or disconfirmed by evidence.

Comprehensiveness

A criterion of a good theory indicating that it applies to and explains a wide variety of relevant phenomena rather than a single isolated behavior.

Applied value

A criterion of a good theory indicating that it is useful in helping improve life or guiding practical interventions and applications.

Parsimony

A criterion of a good theory stating that it should explain phenomena with a manageable number of constructs without introducing unnecessary complexity.

Heuristic value

The ability of a theory to stimulate new questions, ideas, or further research.

Basic research

Research aimed at increasing fundamental knowledge and understanding.

Applied research

Research conducted to address a practical problem or improve a real-world situation.

Implicit theories

Everyday, intuitive assumptions made about what people are like that are not necessarily grounded in formal scientific theory.

Reliability

The consistency or repeatability of a measure, yielding similar results across time or observers under comparable conditions.

Validity

The extent to which a measuring instrument actually measures what it is intended to measure.

Test–retest reliability

A method of assessing consistency by evaluating whether scores remain stable over time when the same test is retaken.

Alternate-forms reliability

A method of assessing consistency by evaluating whether different versions of a test produce comparable results.

Split-half reliability

A method of assessing consistency by checking whether different portions or halves of a single test yield consistent results.

Direct self-report

A measurement technique in which a person directly answers questions about themselves, such as rating a trait on a 10-point scale.

Indirect methods

Assessment techniques that evaluate personality without relying exclusively on direct rating scales, such as asking open-ended questions about an ideal job.

Projective tests

A measurement technique where a person responds to ambiguous material, such as interpreting an inkblot.

Behavioral measures

A personality assessment method in which researchers directly observe or record an individual's behavior.

Correlational research

A research method that examines the relationships between variables; by itself, it does not establish causation.

Experimental research

A research strategy that manipulates an independent variable to investigate its effects on a dependent variable while controlling other factors.

Independent variable (IV)

The presumed cause or variable that is manipulated by the researcher in an experiment.

Dependent variable (DV)

The outcome variable measured by the researcher to determine the effects of manipulating the independent variable.

Case study

A research method that intensively and comprehensively examines one individual's life history, relationships, and behavior.

Psychobiography

The application of a formal personality theory to explain and understand an individual's life history.

Eclecticism

The approach of combining and drawing upon ideas from more than one theoretical perspective rather than relying exclusively on a single theory.

Paradigm

A broad theoretical model or overarching perspective shared by researchers in a discipline.
