descirbe the aim

A

to see if the LTM is impared by semantic similarities and to show that the LTM is not impaied by acoustic similarities

Q

baddeley classic study on the working memory model

what was the experimental design and what were the IV

A

independent group design - 4 groups
* control groups - acoustically dissimilar words - semantically dissimilar words
* experimental groups - acoustically similar words - semantically similar words

Q

Baddeley classic study on the working memory model

describe the procedure

A
  • participants got split into one of 4 groups
  • list of 10 words presented on a projector- 1 every 3 seconds
  • interference task was used - listen to 6 sequences of numbers and write it down
  • had 40 seconds to write words in the correct order
    REPEATED 4 TIMES FOR EACH GROUP
  • interference task used again - copying digits
  • surprise recall used - words placed randomly around the room (all participants ended with 5 scores each)

Q

baddeley classic study on the working memory

describe the results

A

Q

baddeley classic study on the working memory model

describe the conclusion

A
  • the STM and LTM have different coding systems
  • STM used acoustic encoding
  • LTM uses semantic encoding (impaired by semantic similarities)

Q

baddeley classic study on the working memory

positive evaluation points

A
  • volunteer sample - quick and easy
  • highyl controlled - all words has same frequency in everyday life - increases internal validity
  • standardised procedure - words show up every 3 seconds on a projector - increases reliability

Q

baddeley classic study on the working memory

negative evaluation points

A
  • all sample from cambridge - ethnocentric - not representative to TP - lacks population validity
  • lab experiment - artificial memory exp. - lacks ecological validity
  • independent groups design - individual differences (attention levels/ mood) - effects results of the IV
