This system processes visual and spatial information—shapes, colors, locations, and movements. It allows you to mentally navigate a room, rotate an object in your imagination, or remember where you parked. Like the loop, it has limited capacity. Interference occurs if you try to track a moving dot while mentally rotating a shape, as both tasks compete for the same sketchpad.
Here is a detailed breakdown of the Baddeley Model of Working Memory. baddeley memory
No model is perfect. Critics have pointed out that the central executive is sometimes treated as a “little homunculus”—a vague, all-powerful manager whose own inner workings are not fully explained. Others argue that the visuospatial sketchpad may actually be two separate systems (one for visual appearance, one for spatial location). Furthermore, neuroimaging suggests that the components interact more dynamically than Baddeley’s original “hierarchical” diagram implies. Interference occurs if you try to track a
Some essential features of the model include: Critics have pointed out that the central executive
While still the gold standard, the model faces criticism:
