Research Methods and Designs for Personality Theories

Vocabulary flashcards covering personality research methods, experimental designs, psychometrics, cognitive performance tests, projective techniques, and self-report rating scales.

Deduction

A reasoning process that moves from a general premise downward to a specific conclusion, applying an established rule to a single case.

Induction

A reasoning process that builds a broad general conclusion from an accumulation of small, specific observations, useful when generating testable predictions.

Quantitative Research

An empirical approach in which data are expressed as numbers (counts, scores, frequencies) and analyzed statistically using standardized procedures to maximize objectivity and generalizability.

Qualitative Research

An empirical approach in which data are expressed as words, images, or behavioral descriptions using open-ended, context-sensitive procedures to capture meaning and individual perspective.

Reliability

The dependability and consistency of a measure across repeated administrations; an instrument that is unreliable cannot be valid.

Validity

The degree to which an assessment tool measures the specific construct it was designed to evaluate, requiring a precise construct definition and a meaningful measurement method.

Target Patterns of Reliability and Validity

A visual framework illustrating four measurement outcomes: unreliable and unvalid (scattered off-center), unreliable but valid (scattered around center), reliable but not valid (tightly clustered off-target), and both reliable and valid (tightly clustered on target).

True Experiment

A research design that controls every variable influencing the outcome and uses random assignment to experimental and control conditions to establish causal relationships.

Random Assignment

The experimental procedure giving every participant an equal chance of placement in any study condition, minimizing pre-existing group differences and selection bias.

Quasi-Experiment

An experimental setup where random assignment is functionally or ethically impossible, requiring comparison across pre-existing, non-equivalent groups.

Confound

An extraneous variable that differs systematically across non-randomly assigned groups, threatening internal validity by obscuring what caused the observed outcome.

Correlational Study

A research design assessing the statistical association between variables on a scale from $-1$ to $+1$, indicating relationship strength without proving causation or eliminating third variables.

Third Variable Problem

A scenario where an apparent relationship between two correlated variables disappears once an underlying third variable (such as intelligence or socioeconomic status) is statistically controlled.

Case Study

A short, detailed factual account of events within an individual, group, or organization, offering high ecological validity but prone to observer bias and inability to replicate.

Psychometric Methods

Standardized, validated psychological tests and questionnaires governed by explicit administration rules, inquiry procedures, and population norms.

Stylization

The conscious or unconscious modification of personal expressions in written documents (such as letters or diaries) driven by awareness of a potential external audience.

Systematic Observation

A focused diagnostic observation using a predetermined scheme or plan to record only relevant behaviors, increasing efficiency and consistency.

Anamnesis

The clinical collection of life-history data (family, emotional, educational, and professional development), strictly distinguishing objective facts from subjective recollections.

Standardized Interview

An interview structure where the questions and their precise sequence are fixed in advance, minimizing interviewer deviation.

Performance Tests

Diagnostic instruments evaluating cognitive abilities along a success-failure dimension, yielding objective results independent of impression management.

Intelligence Quotient (IQ) Ratio

The classical formula for intellectual functioning expressed mathematically as $IQ = \frac{MA}{CA} \times 100$, relating mental age to chronological age.

g Factor

The theoretical construct of general mental energy or broad cognitive capability underlying one-dimensional intelligence tests.

Kohs Block Design Test

A nonverbal performance intelligence test that measures spatial visualization and manipulation by having examinees reproduce geometric designs using colored cubes.

Raven's Progressive Matrices

A nonverbal reasoning test assessing abstract problem-solving and the $g$ factor by prompting the test-taker to select the missing piece that completes a visual pattern.

Rey-Osterrieth Complex Figure

A neuropsychological performance task involving the copying and delayed recall of an intricate abstract geometric figure to assess visual memory and visuospatial construction.

Tower Test

An executive function task assessing planning and abstract problem-solving by requiring the movement of disks or beads across pegs to reach a target configuration in minimal moves.

Porteus Maze Test

A paper-and-pencil maze instrument scored for cognitive planning, foresight, and impulsivity (such as cutting corners or rushing into blind alleys).

Stroop Task

A classic cognitive control test measuring selective attention and response inhibition by timing participants as they name the ink color of incongruent color words.

Emotional Stroop Task

A variant of the Stroop procedure measuring emotional interference, where threat-related words capture attention and prolong color-naming latencies.

Projective Hypothesis

The theoretical premise that presenting an individual with an ambiguous stimulus compels them to impose structure using their own internal psychological processes and emotions.

Rorschach Inkblot Test

A projective technique created by Hermann Rorschach in 1921 using 10 symmetrical inkblots, scored primarily on how responses are structured (location, form, color, movement) rather than content alone.

Thematic Apperception Test (TAT)

A verbal projective technique developed by Murray and Morgan in 1935 presenting ambiguous pictorial scenarios to elicit narratives that uncover implicit motives.

Draw-a-Person Test

A graphic projective technique introduced by Machover in 1949 involving drawings of individuals of both sexes, evaluated using figure size, placement, detail, and distortions.

Lüscher Color Test

A manipulative projective test developed by Max Lüscher in 1947 where a person orders 8 colors by preference to reveal their current emotional state, psychological needs, and stress level.

Objective Personality Tests

Behavioral assessments evaluating personality through quantifiable task performance where the respondent does not know what specific trait is being measured, reducing faking.

Level-of-Aspiration Test

An objective personality procedure developed by Rotter (1940) evaluating how an individual adjusts predicted future performance in response to prior success and failure.

Objective-Analytic (O-A) Batteries

A comprehensive assessment system developed by Cattell and Warburton (1967) compiling factor-analyzed behavioral, perceptual, and reaction-time tasks to measure traits without self-report.

Unidimensional Questionnaire

A self-report scale designed to assess a single specific psychological construct or symptom severity in depth (e.g., Rosenberg Self-Esteem Scale, BDI, STAI).

Multidimensional Questionnaire

A comprehensive self-report inventory capturing an extensive profile across multiple trait dimensions in a single administration (e.g., 16PF, NEO-PI-R, MMPI, CPI).

NEO-PI-R

A multidimensional questionnaire operationalizing the Five-Factor Model (Openness, Conscientiousness, Extraversion, Agreeableness, Neuroticism), each subdivided into 6 facets.

Minnesota Multiphasic Personality Inventory (MMPI)

A multidimensional assessment featuring clinical diagnostic scales (e.g., depression, paranoia, schizophrenia) paired with specialized validity scales to detect dissimulation.

California Psychological Inventory (CPI)

A multidimensional self-report inventory using folk-concept scales (such as dominance, sociability, and self-control) to evaluate normal-range personality functioning.

Q-Sort

A psychometric rating procedure where 40 to 100+ cards with descriptive statements are sorted across a forced normal distribution, requiring relative comparison between items.

California Q-Set

A standardized 100-item sorting tool developed by Block and completed by trained clinicians/observers to generate quantifiable, longitudinal personality profiles.
