Psychological test (definition)
A systematic procedure for obtaining samples of behavior, relevant to cognitive, affective, or interpersonal functioning, and for scoring and evaluating those samples according to standards
Basic elements of the Definition of psychological testing
- Systematic procedures
- Samples of behavior
- cognitive, affective or interpersonal functioning
- evaluated and scored
- standards based on empirical data
Psychological tests are systematic procedures (Explanation and Rationale)
- are characterizted by planning, uniformity and thoroughness
- must be demonstrably objective and fair to be of use
Psychological tests are sample of behavior (Explanation and Rationale)
- small subsets of a much larger whole
- sampling behavior is efficient because the time available is usually limited
The behaviors sampled are relevant to cognitive, affective, or interpersonal functioning (Explanation and Rationale)
- samples are selected for their empirical or practical psychological significance
- tests are tools
Test results are evaluated and scored (Explanation and Rationale)
- numerical category system is applied to test results
- no questions about what the results of tests are
To evaluated tests it is necessary to have standards based on empirical data (Explanation and Rationale)
- apply common criterion to test results
- the standards used are the only meaning those results have
The goal of testing is…
- to make and assessment of an individual’s standing relative to a selected comparison group
- assessment will be ussually quantitative in nature
- psychometric theory (interpretation is tied to…)
Standardization
- uniformity of teting procedure (Control of extraneous variables)
- explicit reference to the results of a normative sample
The term “psychological test”
per se dominated procedures where responses are scored as correct vs. incorrect
Personality tests

( inventories, questionaires, surveys, etc.)
Ability tests

Psychological tests as tools
- tests serve as a purpose
- tests need to be applied appropriately and skillfully
2 distict points and ways at/in which test are evaluated
- Test as potential tools
2. Tests used for a specific purpose
- Test as potential tools (evaluation)
of primar concern are their technical qualities and the available empirical evidence base
- Tests used for a specific purpose
the focus shifts to the test user and the way she/her handles the test
