Chapter 10: Tests of Intelligence Flashcards
Test’s Appeal
The Theory on which the test is based.
Ease with which the test can be administered
Ease with which the test can be scored
Ease with which results can be interpreted for a particular purpose
Adequacy and appropriateness of the norms
Acceptability of the published reliability and validity indices
Test’s Utility in terms of costs versus benefits
Test Administration
Adaptive testing
Adaptive Testing
Tailored Testing, Sequential Testing, Branched Testing, and Response-Contingent Testing; Tests tailored to the testtaker
Advantages of beginning an Intelligence Test or Subtest at an Optimal Level of Difficulty
Allows the test user to collect the maximum amount of information in the minimum amount of time
It facilities rapport
Minimizes the potential for examinee fatigue from being administered too many items
Routing Test
A task used to direct or route the examinee to a particular level of questions; purpose of the routing test is to direct an examinee to test items that have a high probability of being at an optimal level of difficulty
Teaching Items
designed to illustrate the task required and assure the examiner that the examinee understands
Floor
Lowest level of items on a subtest
Ceiling
Highest-level item on a subtest
Basal Level
Base-level criterion that must be met for testing on the subtest to continue
Ceiling Level
Said to have been reached and testing is discontinued
Testing the Limits
Procedure that involves administering test items beyond the level at which the test manual dictates discontinuance; employed when an examiner has reason to believe that an examinee can respond correctly to items at the hgiher level
Extra Test Behavior
The way the examinee copes with frustration, how the examinee reacts to items considered very easy, the amount of support the examinee seems to require, general approach to the task, behavioral observations that will supplement formal scores
Stanford-Binet Intelligence Scales: Fifth Edition
Designed for administration to asseess as young as 2 and as old as 85 (or older). Yields a number of composite scores, including a Full Scale IQ derived from the administration of 10 Subtests; has two routing scales
Ratio IQ
Ratio of the testtaker’s mental age divided by his or her chronologcal age, multiplied by 100 to eliminate decimals
Devliation IQ
Reflects a comparison of the performance of the individual with the performance of others of the same age in the standardization sample
Age Scales
Different items grouped by age
Point Scale
Test organized into subtests by category of item, not by age at which most testtakers are presumed capable of responding in the way that is keyed as correct
Psychometric Soundness of the SB5
Calculated coeficients were consistently high (0.97-0.98) across age groups; Test-retest reliability coefficient is high. Inter-scorer reliability coefficients reported in SB5 manual ranged from .74 to .97 with an overall median of .90. Content-related evidence of validity was established from expert input to empirical item analysis. Criterion-related evidence was presented in the form of both concurrent and predictive data. Predictive Validity evidenced by correlations with measures of achievement and detailed findings reported in the manual. Factor analytic studies were presented in support of the construct validity of the SB5.
Adaptive Testing
Testing individually tailored to the testtaker; also known as tailored testing, sequential testing, branched testing, and response-contingent testing; designed to mimic automatically what a wise examiner would do.
