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

Score decline following fatigue from repeated assessments

Answer

Examiner bias introduced through repeated administration

Answer

Scoring errors caused by the examiner rushing through the protocol

Question 2

Discriminant (divergent) validity is demonstrated when:

Accepted Answer

A test shows low correlations with measures of theoretically unrelated constructs

Answer

A test correlates highly with measures of the same construct

Answer

Different raters produce identical scores on the same protocol

Answer

A test accurately predicts future real-world outcomes

Question 3

The Flynn Effect refers to:

Accepted Answer

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

Answer

Improvement in individual test scores with practice across retesting

Answer

The decline in cognitive performance associated with normal aging

Answer

Score inflation caused by repeated exposure of test items to the public

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When a test's norms are significantly outdated, what problem is most likely to occur?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

The test becomes unreliable due to item deterioration over time

Answer

The standard error of measurement increases substantially

Answer

The test ceiling lowers, producing more ceiling effects

Question 5

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

Accepted Answer

Scoring that requires subjective judgment or behavioral observation

Answer

Tests composed entirely of multiple-choice items

Answer

Assessments administered and scored entirely by computer

Answer

Tests normed on a very large standardization sample

Question 6

A 'floor effect' in testing occurs when:

Accepted Answer

Items are too difficult, causing scores to cluster near the minimum

Answer

The physical testing environment negatively affects performance

Answer

Items are too easy, causing scores to cluster near the maximum

Answer

The normative sample included too few low-ability participants

Question 7

Which of the following best describes 'construct validity'?

Accepted Answer

The extent to which a test accurately measures the theoretical concept it purports to measure

Answer

The degree to which test content represents the full range of the skill domain

Answer

The ability of a test to predict future performance on related real-world tasks

Answer

The consistency of scores produced across multiple test administrations
