WAIS Psychometric Properties and Norms 3

Question 1

The Flynn Effect refers to which observed trend in IQ test norms?

Accepted Answer

Rising raw score performance over generations requiring periodic renorming

Answer

The Flynn Effect is the well-documented phenomenon of rising raw score performance across generations, necessitating updated norms.

Question 2

When interpreting WAIS-IV subtest scores, a scaled score of 10 represents performance at which level?

Accepted Answer

Exactly at the population mean

Answer

WAIS-IV subtest scaled scores have a mean of 10 and SD of 3, so a score of 10 is exactly average.

Question 3

Which WAIS-IV reliability method is most appropriate for evaluating the consistency of Processing Speed subtests?

Accepted Answer

Test-retest reliability

Answer

Processing Speed subtests are speeded tasks where split-half methods are inappropriate; test-retest reliability is the standard approach.

Question 4

What is the standard error of measurement (SEM) primarily used for in WAIS-IV score interpretation?

Accepted Answer

Constructing confidence intervals around obtained scores

Answer

The SEM is used to build confidence intervals, expressing the range within which the true score likely falls.

Question 5

Discriminant validity evidence for the WAIS-IV is typically demonstrated by showing that WAIS-IV scores do NOT correlate highly with measures of which construct?

Accepted Answer

Personality traits

Answer

Discriminant validity is shown when WAIS-IV scores correlate weakly with theoretically unrelated constructs such as personality traits.
