Baddeley's study on encoding

• What was Baddeley's aim in his study?

  To see encoding differences in STM/LTM
• How many sets of words were given to each group in Baddeley's experiment?

  12 sets of five words
• What type of words did Group A have in Baddeley's study?

  Similar sounding words
• What type of words did Group B have in Baddeley's study?

  Dissimilar sounding words
• What type of words did Group C have in Baddeley's study?

  Words with similar meanings
• What type of words did Group D have in Baddeley's study?

  Words with dissimilar meanings
• Which groups tested STM in Baddeley's study?

  Groups A and B
• Which groups tested LTM in Baddeley's study?

  Groups C and D
• How long after being given the words were groups C and D asked to recall them?

  20 minutes
• Which group recalled fewer words in STM in Baddeley's study?

  Group A
• Which group recalled fewer words in LTM in Baddeley's study?

  Group C
• How did words with similar sounds affect recall in STM?

  They were more poorly recalled
• How did words with similar meanings affect recall in LTM?

  They were more poorly recalled
• What did Baddeley conclude about encoding in STM?

  It is encoded by sound
• What did Baddeley conclude about encoding in LTM?

  It is encoded by meaning
• Why is controlling extraneous variables a strength?

  Increases certainty in affected factors
• How was hearing controlled in Baddeley's study?

  Participants were given a hearing test
• What does Brandimonte et al.'s research suggest about STM encoding?

  STM can use visual encoding
• What is a weakness regarding LTM testing in Baddeley's study?

  20 minutes may not test LTM
• What does the potential weakness regarding LTM testing mean for the conclusion?

  Lacks validity
• What did Baddeley's study of encoding show?

  Two memory types have qualitative differences
