Answer 1

.baddley and hitch 1974

Question 2

What does the working memory model consist of?

Answer 2

-central executive
-visuospatial sketchpad
-phonological loop
-episodic buffer
-long term memory

Question 3

What is the central executive?

Answer 3

-receives environmental stimuli and passes it to appropriate store

Question 4

What is the visuospatial sketchpad?

Answer 4

What are the limitations to the model?

Answer 8

-doesn’t capture evidence for more stores:
.HM could make new procedural ltm but not semantic or episodic
