Evaluation: The working memory model

Question 1

State the 1st evaluation point of the working memory model.

Answer 1

Dual task performances
- Hitch & Baddeley study

Task 1:
- Occupied central executive (True/False task)

Task 2:
- Involved articulatory loop or both CE & AL
- Asked to continuously repeat "The"
- Asked to say random numbers 
Reults:
- Task 1 = Slower
- Task 2 = Faster

Question 2

What does the 1st evaluation point of working memory model suggest?

Answer 2

• Demonstrates dual task performance effects & shows central executive is one component of working memory

Question 3

State the 2nd evaluation point of the working memory model.

Answer 3

Problems with using case studies

• Brain injuries = traumatic
• Therefore, may cause change in behaviour which results in person to perform worse in tasks
• Others may have other difficulties
• This is an issue as most support evidence for WMM comes from case studies

Question 4

State the 3rd evaluation point of the working memory model

Answer 4

Evidence from brain-damaged patients

• Shallic & Warrington studied a patient called KF
• His short-term forgetting of auditory information was much greater than that of visual stimuli
• Therefore, KF’s brain is restricted to the phonological loop
