A 'practice effect' in neuropsychological testing refers to:
Answer: Score improvement due to prior familiarity with the test format or items
Practice effects occur when retest scores improve because of familiarity with the task demands rather than reflecting a true change in the underlying ability.
Discriminant (divergent) validity is demonstrated when:
Answer: A test shows low correlations with measures of theoretically unrelated constructs
Discriminant validity is established when a test does NOT correlate highly with measures of constructs it theoretically should not be related to, showing specificity.
The Flynn Effect refers to:
Answer: The documented rise in average IQ scores across populations over successive generations
The Flynn Effect describes the historical rise in IQ test scores across populations over the 20th century, which is why tests must be periodically renormed.
When a test's norms are significantly outdated, what problem is most likely to occur?
Answer: Scores may be inflated because current examinees outperform the older normative sample
Because of the Flynn Effect, individuals tested against outdated norms are compared to a lower-performing historical sample, causing scores to appear artificially elevated.
Inter-rater reliability is most critical in which testing situation?
Answer: Scoring that requires subjective judgment or behavioral observation
Inter-rater reliability is essential whenever scoring requires qualitative judgment or observation, as two different raters may interpret or score the same response differently.
A 'floor effect' in testing occurs when:
Answer: Items are too difficult, causing scores to cluster near the minimum
A floor effect occurs when test items are too difficult for the examinee population, causing scores to pile up at the lowest possible values and preventing differentiation among low-ability individuals.
Which of the following best describes 'construct validity'?
Answer: The extent to which a test accurately measures the theoretical concept it purports to measure
Construct validity refers to how well a test actually measures the underlying theoretical construct (e.g., working memory, processing speed) it was designed to assess.
