Working Memory Model

Question 1

What does the WMM suggest about the STM

Answer 1

It’s made up of the central executive, phonological loop, visuospatial sketchpad and episodic buffer

Question 2

What is the central executive

Answer 2

Its described as ‘attentional process’ with a very limited processing capacity and whose role is to allocate tasks to the 3 slave systems

Question 3

What is the phonological loop

Answer 3

Processes auditory information and allows for maintenance rehearsal by being made up of the articulatory process (stores words you hear) and the phonological loop

Question 4

Explain. the WMM

Answer 4

See resource

Question 5

What is the visa-spatial sketchpad

Answer 5

Combines visual and spatial information processed by other stores giving us a complete picture. For example - Recalling a famous landmark. The VSS is divided into the inner scribe and visual cache. The capacity of the VSS is 4-5 chunks

Question 6

Explain the episodic buffer

Answer 6

It interrogates all types of data processed by other stores and so is described as the storage component of the CE as well. as linking STM to LTM

Question 7

Give a - (CENDP)

Answer 7

The CE hasn’t been precisely defined. The term process is too vague and the CE may be made up. of several sub-components or part of a larger component of the WMM draws doubts about the accuracy. of working its deception

Question 8

Give a + (KF)

Answer 8

KF provides support for the WMM because their findings show KF had poor STM recall for auditory, but increased for visual. Suggesting that the components of memory which process auditory and visual stimuli are separate (like the WMM says)

Question 9

Give a + (SDT)

Answer 9

Studies of dual-task performance, where participants undertook a visual and verbal task simultaneously, shows decreased performance for tasks and supports the idea that the CE has limited processing capacity and the slave systems are in competition for the tasks and resources

Question 10

Give a + (NS)

Answer 10

Neuroscanning evidence showed a positive correlation between increasing cognitive load processed by the CE and increasing levels in the prefrontal cortex. Supporting the idea the CE has a role in allocating tasks to slave systems and has limited processing capacity, reflected by the increased brain activation levels, suggesting that the WMM is accurate in its mechanism of the CE
