How does aging affect the components of the Working Memory Model?

• A. All components improve with age.
• B. Possible decline in Central Executive and Visuospatial Sketchpad efficiency; Phonological Loop may be preserved in some contexts; overall working memory tends to decline with age.
• C. Aging has no effect on working memory.
• D. Phonological loop declines most; others improve.

Answer: (B)

Aging affects working memory unevenly across its components. The central executive, which is the control system that directs attention, updates information, and allocates mental resources, often shows age-related decline. Slower processing speed and reduced executive control mean older adults may struggle with tasks that require switching between tasks, inhibiting irrelevant information, or managing multiple streams of data.

The visuospatial sketchpad, responsible for holding and manipulating visual and spatial information, also tends to become less efficient with age. This shows up in tasks that require mental imagery, spatial awareness, or tracking movements in space, where performance can drop as people get older.

The phonological loop, which briefly stores verbal information and uses subvocal rehearsal to keep it active, is usually more resilient in healthy aging. Verbal memory and language skills can remain strong for many older adults, especially in familiar or routine contexts. That said, in demanding situations that require rapid or extensive phonological processing, you might notice slower rehearsal or smaller effects on performance.

Because the central executive and visuospatial sketchpad are more vulnerable and because the phonological loop is often preserved, the overall pattern is a tendency for working memory to decline with age, with variability based on task demands and individual differences.

So the best description is that there may be declines in the central executive and visuospatial sketchpad, the phonological loop may be preserved in many contexts, and overall working memory tends to decline with age.
