In WMS-IV, which indices describe memory modalities across auditory and visual domains?

• A. Immediate Memory Index and Delayed Memory Index.
• B. Verbal Memory Index and Visual Spatial Index.
• C. Auditory Memory Index and Visual Memory Index.
• D. Working Memory Index and Processing Speed.

Answer: (C)

In the WMS-IV, memory abilities are examined separately for different sensory modalities, specifically auditory and visual. The two indices that capture this modality-specific memory are Auditory Memory Index and Visual Memory Index. The Auditory Memory Index measures how well a person can encode, store, and retrieve information heard verbally, such as stories or sequences. The Visual Memory Index assesses memory for information seen visually, like designs or complex figures. This separation allows clinicians to see whether someone’s memory performance is stronger for auditory material or visual material, rather than mixing all memory tasks together.

The other options mix memory concepts with non-modality-specific or different domain constructs. Immediate Memory and Delayed Memory indices refer to memory performance across tasks but aren’t tied to a single sensory modality. Verbal Memory Index and Visual Spatial Index aren’t the standard modality-specific indices on the WMS-IV, and Working Memory and Processing Speed measure other cognitive processes rather than the distinct auditory versus visual memory modalities. Therefore, the best answer is the combination of Auditory Memory Index and Visual Memory Index.
