The Theory Lab (Personality Theory & Approaches)
This distinction separates a relatively stable, enduring personality characteristic from a temporary, situational emotional condition.
What is the difference between trait and state?
Embedded within structured tests like the MMPI, this mechanism detects dishonest, random, or defensive response patterns.
What is a validity scale?
The core assumption that when presented with ambiguous stimuli, individuals unconsciously project their internal feelings, motives, and conflicts.
What is the projective hypothesis?
A systematic clinical appraisal of a client's current mental functioning, covering appearance, mood, affect, thought process, and orientation.
What is the Mental Status Examination?
A cognitive bias where an evaluator's overall positive impression of an individual influences their rating of specific traits or abilities.
What is the halo effect?
This perspective seeks to uncover general, universal laws of personality that apply across large groups of people.
What is the nomothetic approach?
A statistical technique used to reduce a large number of test items into a smaller set of underlying dimensions or traits.
What is factor analysis?
The standard administration of Henry Murray's Thematic Apperception Test typically involves presenting this specific number of cards (though clinicians often use a selection of 10 to 12).
What is 20 (or 31 including the blank card)?
An agreement established between therapist and client outlining goals, expectations, confidentiality bounds, and session schedules.
What is a therapeutic contract?
The tendency for individuals to accept vague, high-generality personality statements (like horoscopes) as highly accurate descriptions of themselves.
What is the Barnum (or Forer) Effect?
Rather than comparing individuals to group norms, this approach focuses on the unique, individual structure of a single person's personality.
What is the idiographic approach?
Tests designed to predict specific, real-world outcomes or performance indicators rather than measure theoretical constructs.
What are criterion-oriented tests (or empirical criterion keying)?
The crucial second phase of inkblot administration where the examiner asks the subject where they saw what they reported and what features made it look that way.
What is the inquiry phase?
A client's level of psychological, cognitive, and social adjustment prior to the onset of an illness or injury.
What is premorbid functioning?
The behavioral phenomenon where individuals alter their behavior simply because they know they are being observed or assessed.
What is reactivity?
Freedom, inner harmony, and world peace are all examples of this type of Rokeach value, which represents an ultimate end-state of existence rather than a daily behavior.
What is a terminal value?
The difference between the rate of new cases of a disorder during a specific period versus the total number of active cases in a population.
What is the difference between incidence and prevalence?
The standard, highly structured scoring system developed to improve the reliability and validity of the Rorschach inkblot test.
What is the Exner Comprehensive System?
The legal and ethical obligation stemming from Tarasoff v. Regents requiring clinicians to breach confidentiality if a client poses an imminent threat to an identifiable individual.
What is the duty to warn (and protect)?
A rating mistake where an examiner consistently rates candidates higher (or lower) than their actual performance merits.
What is a leniency/severity bias?
A scoring method where an individual's score on one scale is evaluated relative to their own scores on other scales, rather than compared to a normative population.
What is ipsative scoring?
The psychometric process of evaluating an individual's score against a standardized benchmark group.
What is norm-referenced testing?
Projective instruments consisting of incomplete stems (e.g., "My mother always...") designed to elicit spontaneous personal responses.
What are sentence completion tests?
The spectrum of intake interviews ranging from completely open-ended and unstructured to highly standardized formats like the SCID.
What is interview structure / structured vs. unstructured interviews?
The systemic error introduced when a psychological instrument yields systematic differences in scores across distinct demographic groups due to unstandardized cultural variables.
What is cultural bias?
