Question 30

Within the WAIS, what is the difference between Processing Speed and Perceptual Reasoning?

Answer 30

Processing Speed refers to the ability to process simple information rapidly and accurately, whereas Perceptual Reasoning indexes spatial processing and visual-motor integration.

Question 31

We have recently considered both the WAIS-IV assessment of intellectual ability and structured interviewing assessment measures. What are some benefits common to both structured interviews and a WAIS? What might be some drawbacks?

Answer 31

Benefits: both have increased reliability, increased validity, are standardized, and are useful. Drawbacks: more expensive and time consuming (to achieve this standardization, lengthy training is often required), the clinician has less freedom if a client provides an interview/assessment response that is not listed in the manual, scripts may be awkward to follow.

Question 32

You suspect a client may have difficulties with abstract verbal reasoning , and that she will also have excellent abilities when manipulating mental problems. On which scale (not subtest) of the WAIS-IV will she show relatively poorer performance? On which scale (not subtest) will she show relatively better performance?

Answer 32

Relatively poorer performance on Verbal Comprehension Index (VCI), and relatively better performance on Working Memory Index (WMI).

Question 33

What does it mean if someone scores below a 70 in the WAIS and what are the potential implications?

Answer 33

Scoring below 70 would put someone in the intellectually disabled range, which matters because it can help determine if they are competent and if they are eligible for special services, like at school. These implications include (but not limited to) domains such as legal, educational, and occupational.

Question 34

In terms of psychometrics, what are the strengths of the WAIS-IV?

Answer 34

High standardization, high reliability for FSIQ and Subscales, good validity for FSIQ and Subscales, and high utility. This is one of the best available assessments in clinical psychology and is widely used in consequential settings (legal, mental health, educational).
