WPPSI - Wechsler Preschool and Primary Scale of Intelligence Processing Speed Subtests Questions and Answers

Question 1

Which of the following subtests are the two primary measures used to derive the Processing Speed Index (PSI) for children in the 4:0-7:7 age band of the WPPSI-IV?

Accepted Answer

Bug Search and Cancellation

Answer

For the older age band (4:0-7:7) on the WPPSI-IV, the Processing Speed Index is primarily composed of the Bug Search and Cancellation subtests. Animal Coding is also a processing speed subtest but is supplemental, not primary.

Question 2

A 5-year-old child is administered the Bug Search subtest. The task requires the child to scan a search group of bugs and mark the one that matches the target bug. This task primarily assesses which cognitive ability?

Accepted Answer

Visual-motor coordination and speed of visual search

Answer

The Bug Search subtest is designed to measure a child's speed and accuracy of visual identification, decision-making, and implementation. It specifically assesses skills like visual scanning, discrimination, and visuomotor coordination under timed conditions.

Question 3

The Processing Speed subtests on the WPPSI-IV, such as Bug Search and Animal Coding, were designed to be more developmentally appropriate for young children than previous versions. A key adaptation is the use of:

Accepted Answer

An ink dauber and engaging, colorful stimuli

Answer

The WPPSI-IV Processing Speed subtests were intentionally made more 'game-like' and child-friendly. This includes using an ink dauber, which reduces fine motor demands, and employing engaging, familiar images like bugs and animals instead of abstract symbols.

Question 4

An examiner is testing a 6-year-old and administers the Cancellation subtest. In this subtest, the child is presented with a page of pictures and asked to mark specific target images. What is a key feature of the Cancellation subtest's design?

Accepted Answer

It includes both a random and a structured arrangement of objects.

Answer

The Cancellation subtest on the WPPSI-IV distinctively includes two items: one with a random arrangement of objects and one with a structured arrangement. This allows the examiner to gather information about how the child's performance may differ based on the visual organization of the task.

Question 5

The Processing Speed Index (PSI) is available for which age band of the WPPSI-IV?

Accepted Answer

Ages 4:0 - 7:7 only

Answer

The Processing Speed Index (PSI) and its corresponding subtests are specifically designed for and administered to the older age band of the WPPSI-IV, which is children aged 4 years, 0 months to 7 years, 7 months.
