BASIC CONCEPTS IN PSYCHOLOGICAL TESTING Flashcards
Most psychological tests can be categorized as measuring
Intellectual Abilities
Attitudes, Interests, and Values.
Aspects of Personality
Psychopathology.
a systematic procedure for observing and describing a person’s behavior in a standard situation (Cronbach, 1970)
Psychological Test?
two of the most important features of psychological test
First, tests are ideally designed to be objective measures of psychological characteristics.
Second, the need for test standardization
The clinician then scores or interprets the client’s responses using ____________, _________________, meaning rules that are based on empirical data
reasonably objective, empirically derived scoring rules
The goal is to ensure that the differences among clients’ test scores reflect ___________________
differences among the clients themselves,
Everyone who takes the same test should be exposed to the same set of materials and evaluated according to the same scoring criteria
Standardization
The principles of ______________ and _________allow us to evaluate the quality of psychological tests using the same logic that we apply to evaluating the quality of psychological experiments
objectivity and standardization
objectivity and standardization reduces or eliminates the impact of extraneous, or confounding, variables—such as _____________ or ____________, so that test results can be attributed to just one source, namely the characteristics of the client.
scoring procedures or the tester’s personal characteristics
tests differ from most other clinical assessment techniques in three ways
- a client’s test responses can be quantitatively compared with statistical norms established by the responses of hundreds or thousands of other people who have taken the same test under standardized conditions.
- A test can be taken in private, without a clinician present, meaning that there might not be observational data to supplement test results.
- Tests can be administered in groups as well as individually
ensures that everyone who takes a test receives the same instructions and experiences the same (or very similar) testing conditions.
Standardization
test construction procedure in which items are chosen because they appear on logical grounds to measure the characteristic of interest to the tester.
Analytic Approach (Rational Approach)
Psychologists who take an analytic approach, sometimes called the rational approach, begin by asking:_______________________________ They then build their test by creating items that answer these questions.
What are the qualities we want to measure, and how do we define them?
This approach can be faster and less expensive because it does not require the test developer to pre-test many items with many people before settling on the ones that will comprise the test.
Analytic Approach
These procedures are also ideal for psychologists who for some reason need to develop a test on short notice, and especially for those who will use their test to evaluate a hypothesis based on a particular theory.
Analytic Approach
Example: there is a theory that includes “geekiness” as an important personality dimension. But there is no “geekiness” test available. What approach will researchers use in this situation?
Analytic approach
