WAIS Perceptual Reasoning Index (PRI) 4

Question 1

Figure Weights, an optional PRI subtest on the WAIS-IV, primarily measures which cognitive skill?

Accepted Answer

Quantitative and inductive reasoning using visual weight analogies

Answer

Figure Weights requires examinees to determine what weight is needed to balance a scale, measuring quantitative reasoning and inductive logic.

Question 2

A clinician notices an examinee performs well on Matrix Reasoning but poorly on Block Design and Visual Puzzles. Which interpretation is most defensible?

Accepted Answer

Stronger abstract reasoning relative to spatial construction and visualization

Answer

This profile separates nonverbal inductive reasoning (Matrix Reasoning) from visuospatial construction tasks, suggesting a relative strength in abstract reasoning.

Question 3

On the WAIS-IV, which PRI subtest has the highest loading on a general spatial visualization factor?

Accepted Answer

Visual Puzzles

Answer

Visual Puzzles was specifically designed and validated as a strong measure of spatial visualization and mental synthesis ability.

Question 4

When interpreting a PRI score for a visually impaired examinee, a clinician should:

Accepted Answer

Note the score has limited validity because the subtests heavily rely on intact visual acuity

Answer

PRI subtests are inherently visual and assume adequate visual acuity; sensory impairments directly compromise task demands and score validity.

Question 5

The 'process approach' to WAIS-IV Block Design scoring focuses on:

Accepted Answer

Analyzing error patterns, self-corrections, and strategy use beyond the total score

Answer

The process approach examines qualitative features of performance such as rotation errors, broken configurations, and working style to inform clinical hypotheses.
