Which two core subtests make up the Processing Speed Index (PSI) on the WAIS-IV?
Answer: Symbol Search and Coding
The WAIS-IV PSI is composed of the Symbol Search and Coding subtests.
What cognitive ability does the Processing Speed Index primarily measure?
Answer: Speed of mental and graphomotor processing of simple visual information
PSI reflects how quickly one processes simple visual information and produces a motor response.
On the Coding subtest, what is the examinee asked to do?
Answer: Copy symbols paired with numbers using a key, as fast as possible
Coding requires copying symbols matched to numbers using a reference key within a time limit.
What does the Symbol Search subtest require the examinee to do?
Answer: Indicate whether target symbols appear in a search group
In Symbol Search the examinee scans a search group to decide if a target symbol is present.
A very low PSI score with average scores on other indexes most often suggests difficulty with which area?
Answer: Speed and efficiency of visual-motor performance
An isolated low PSI typically points to slowed visual-motor processing efficiency rather than reasoning deficits.
Which condition is commonly associated with reduced Processing Speed Index scores?
Answer: ADHD and certain learning disabilities
ADHD and some learning disabilities are frequently linked to lowered processing speed.
The Processing Speed Index contributes to which broader composite score?
Answer: The Full Scale IQ (FSIQ)
PSI is one of the four indexes that combine into the Full Scale IQ.
