Question 11

What did Baddely do?

Answer 11

4 sets of 10 words
each word shown for 3 seconds
end of each set recall words in order
set 1 : acoustic similar
set 2 : acoustic dissimilar
set 3 : semantic similar
set 4 : semantic dissimilar

Question 12

What did Baddely conclude?

Answer 12

difficulty remembering acoustic similar words in STM

difficulty remembering semantic similar in LTM

Question 13

What is the weaknesses of Baddelys experiment?

Answer 13

• baddely may not have tested LTM
• STM may not be exclusively acoustic
• LTM may not be exclusively semantic
