Question 2

What term describes a subset of WAIS subtests administered when time is limited but a reliable estimate of general ability is still needed?

Accepted Answer

Abbreviated battery

Answer

An abbreviated battery uses a reduced set of subtests to estimate FSIQ when full administration is not feasible.

Question 3

The WAIS-IV replaced which earlier version of the instrument?

Accepted Answer

WAIS-III

Answer

The WAIS-IV (2008) replaced the WAIS-III (1997), updating norms, floor/ceiling, and factor structure.

Question 4

Which structural change distinguished WAIS-IV from WAIS-III regarding index scores?

Accepted Answer

WAIS-IV eliminated the Perceptual Organization Index and replaced it with the Perceptual Reasoning Index

Answer

WAIS-IV replaced the Perceptual Organization Index (POI) of WAIS-III with the Perceptual Reasoning Index (PRI), reflecting updated factor analytic findings.

Question 5

In the WAIS-IV factor structure, which index score has the highest g-loading and contributes most to FSIQ?

Accepted Answer

Verbal Comprehension Index

Answer

The Verbal Comprehension Index typically shows the highest g-loading in WAIS-IV factor analyses, reflecting strong association with general intelligence.
