The Working Model Of Memory

Question 1

Working memory model

Answer 1

• short term memory only
• active processor: stores work together to process information.
• explains dual tasking: 2 thing at once (using two separate stores)

Question 2

Draw the working memory model

Answer 2

X

Question 3

Central executive

Answer 3

• the controller
• delegates to the slaves (determine where the brain’s attention should be directed)
• problem solves
• limited capacity
• deals with all types of information

Question 7

Baddeley and hitch (1976)- two stores

Answer 7

• Gave participants two studies to do simultaneously.
  -Task 1: occupied central executive
  -Task 2: occupied the articulatory loop OR both the central executive AND the articulatory loop.
• found that doing tasks that involve the same component causes difficulty but when different components are used, performance is not effected.
