PRINCIPLES OF PSYCHOLOGICAL TESTING
INTRODUCTION TO
PSYCHOLOGICAL TESTING
JEMABEL GONZAGA-SIDAYEN, RP, RPm, M.A.
Psychological testing • a field characterized by the use of samples of behavior in order to infer generalizations about a given individual.
• Sample behaviors are gathered through the responses to the psychological test and these responses are often compiled into statistical tables that allow the evaluator to compare the behavior of the individual being tested to the responses of a norm group.

ACHIEVEMENT

STRUCTURED PERSONALITY TEST
PROJECTIVE TECHNIQUES
TYPES OF TESTS
• Individual tests are those that can be given to only one person at a time.
• Group test can be administered to more than one person at a time by a single examiner.
TYPES OF TESTS
• ACHIEVEMENT – refers to previous learning • APTITUDE – refers to the potential for learning or acquiring a specific skill
• INTELLIGENCE – general potential to solve problems; capacity for abstract thinking TYPES OF TESTS
• STRUCTURED PERSONALITY TEST – usually a “self-report” variety that requires the subject to choose between two or more alternative responses
• PROJECTIVE TECHNIQUES – either the stimulus or the required response or both are ambiguous.
•There are basic concepts and fundamental ideas that underlie all psychological and educational tests.
RELIABILITY
• Refers to the accuracy, dependability, consistency, or repeatability of test results.
• The degree to which test scores are free of measurement errors
VALIDITY
• Meaning and usefulness of test results • The degree to which a certain inference or interpretation based on the test is appropriate
• What does the psychological test measure? HISTORICAL PERSPECTIVE
• EARLY ANTECEDENTS:
Du Bois (1970, 1972) – Chinese had a relatively sophisticated civil testing program more than 4000 years ago.
China give oral examinations to help determine work evaluations and promotion decisions.
