In WMS-IV, which indices summarize immediate memory and delayed memory across auditory and visual domains?

• A. Auditory Memory Index and Visual Memory Index.
• B. Immediate Memory Index and Auditory Memory Index.
• C. Delayed Memory Index and Visual Memory Index.
• D. Immediate Memory Index and Delayed Memory Index.

Answer: (D)

In WMS-IV, memory is summarized by indices that combine performance across modalities. The key idea here is identifying indices that span both auditory and visual information, for both immediate and delayed recall. The Immediate Memory Index pools tasks that require holding information in memory right after it’s presented, across both auditory and visual inputs. The Delayed Memory Index pools tasks that require recalling information after a delay, again across both modalities. Together, they provide a cross-domain view of memory functioning.

So the best pairing is Immediate Memory Index and Delayed Memory Index. The other options focus on a single modality (either auditory or visual) or mix indices in a way that doesn’t capture memory across both domains.
