Question 1

One strength

Answer 1

Baddley identified clear difference between two memory stores
Able to say STM is acoustic LTM is semantic
Important step in our understanding of the memory system led to multi store model

Question 2

What’s a limitation

Answer 2

Baddley study used artificial stimuli

Word list no personal meaning to participant
So Baddley a finding may not tell us much about coding in different kind of memory tasks especially everyday life

Suggest findings from this study have limited application

Question 3

What’s another strength

Answer 3

Jacob Study has been replicated
Although study is old and lacked adequate control
Jacob’s findings have been confirmed by new and better controlled studies

Suggest Jacob test is valid test of digit span

Question 4

Another limitation

Answer 4

Limitation of miller research may have overestimated STM capacity

Nelson Cowan 2001 reviewed other research and concluded that STM capacity is 4 plus or minus 1 chunks
Suggest lower end of Miller estimate (5 items more appropriate than seven
