Study Notes

Introduction to Testing

Discusses the evolution of testing and its significant achievements.
A test is a measurement device/technique used to quantify behavior, aiding in predicting behavior.
An item is a specific stimulus to which a person responds, either scored, evaluated, or counted.
A psychological test is a systematic procedure to obtain behavior samples relevant to cognitive, affective, or interpersonal functioning.
Psychological assessment integrates information from multiple sources to describe, predict, explain, diagnose and make decisions about a person. It uses various psychological techniques and tools.

Taxonomy of Psychological Assessment

Measurement includes correct/incorrect responses and tests (e.g., questionnaires, inventories).
Non-measurement includes interviews, observations, and other questionnaires/checklists.
Psychological assessment incorporates both quantified (testing) and unquantified (observation, interviews) information.

Basic Elements of the Definition of Psychological Tests

Psychological tests are systematic procedures characterized by planning, uniformity, and thoroughness.
Psychological tests are samples of behavior.
Behaviors sampled through tests are related to cognitive, psychological significance.
Tests are objective and fair, efficiently applicable to limited time.

Parties Involved in Testing

Test authors and developers conceive, prepare, and develop tests, distributing through publications.
Test publishers publish and market tests.
Test reviewers critique tests.
Test users are those selecting tests.
Test sponsors are institutions or agencies contracting with test developers/publishers.
Test administrators administer tests to individuals or groups.
Test takers participate and respond to the tests.
Test scorers quantify responses .
Test score interpreters analyze and interpret results.

Categories of Tests

Ability tests sample knowledge, skills, or cognitive functions. These include achievement tests (measure previous learning) and aptitude tests (measure potential for specific skills) and intelligence tests (measuring general potential to solve problems, adapt, and learn).
Personality tests measure typical behavior patterns, traits, temperaments, and dispositions. There are structured (objective, self-report) and unstructured/projective (ambiguous stimuli) types.

Current Uses of Psychological Tests

Tests are important in decision-making for selection, placement, classification, or group diagnosis.
Tests are used in psychological research across many areas such as differential, developmental, abnormal, educational, social, and vocational psychology.
Tests can also be used for self-understanding and personal development.
