Baddeley's working memory model proposes which three components for the short-term workbench?
AIconic store, echoic store and haptic store
BPhonological loop, visuospatial sketchpad and central executive
CEpisodic buffer, semantic buffer and procedural buffer
DSensory register, encoding stage and retrieval stage
Answer & Solution
Correct answer: B. Phonological loop, visuospatial sketchpad and central executive
1. Box 6.1 introduces working memory as a multi-component view of short-term memory.
2. It was first proposed by Baddeley in 1986.
3. The first component is the phonological loop holding limited number of sounds.
4. The second is the visuospatial sketchpad storing visual and spatial information.
5. The third, called the central executive, allocates resources and monitors behaviour.
6. Hence the three components are phonological loop, visuospatial sketchpad and central executive.
