BCP Psychometric Concepts and Test Theory Questions and Answers 3

Question 1

A 'practice effect' in neuropsychological testing refers to:

Accepted Answer

Score improvement due to prior familiarity with the test format or items

Answer

Practice effects occur when retest scores improve because of familiarity with the task demands rather than reflecting a true change in the underlying ability.

Question 2

Discriminant (divergent) validity is demonstrated when:

Accepted Answer

A test shows low correlations with measures of theoretically unrelated constructs

Answer

Discriminant validity is established when a test does NOT correlate highly with measures of constructs it theoretically should not be related to, showing specificity.

Question 3

The Flynn Effect refers to:

Accepted Answer

The documented rise in average IQ scores across populations over successive generations

Answer

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.

Question 4

When a test's norms are significantly outdated, what problem is most likely to occur?

Accepted Answer

Scores may be inflated because current examinees outperform the older normative sample

Answer

Because of the Flynn Effect, individuals tested against outdated norms are compared to a lower-performing historical sample, causing scores to appear artificially elevated.

Question 5

Inter-rater reliability is most critical in which testing situation?

Accepted Answer

Scoring that requires subjective judgment or behavioral observation

Answer

Inter-rater reliability is essential whenever scoring requires qualitative judgment or observation, as two different raters may interpret or score the same response differently.
