Baddelley Classic Study

Question 1

What was the aim of Baddeley’s Study?

Answer 1

• investigate weather LTM was badly impaired with acoustically similar or semantically similar words used

Question 2

What was the IV and DV of Baddelley’s Study?

Answer 2

IV
- acoustically similar or disimilar words
- semantically similar or disimillar words

DV
- The correct order of words recalled

Question 3

Why include task for each trail as well as the interferance task was this important?

Answer 3

TASK in each up to 4th trial
- Participants had 6 sequence of 8 digits they had to recall which l
- to stop participants from recalling the words they had learn in their STM but LTM –> prevent information going to STM
- They had 8 seconds to to write each sequences

In addition
- 1 min to recall and write down ten word list items

INTERFERANCE TASK
- included 15 mins of copying sequences of digits at their own pace

Question 4

How did Baddelley Controll his classic study?

Answer 4

• HEARING TEST
• participants required to to write each word down (the words were in random order) after hearing the word to check they were able to hear
• 3 participants excluded because they didn’t score 100%
• ## Standardised procedure

Question 5

What did the sample include?

Answer 5

• men and women recruited from Applied Psychology Unit

Question 6

What was the procedure of Baddelley’s study?

Answer 6

• HEARING TEST to remove any confounding variables by listening and copying each word which was listed in random order
• 10 list of words were projected on a slide with every word shown 3 seconds in the correct order
• They then required to complete 6 task involving remembering digits
• They then recalled the list of words in the correct order for **1 min **
• This was completed on the 4th trial
• After 4th trial, participants did an interferance task of copying sequences of digits at their own pace
• they were then given a surprise retest to recall the list of words in correct order once more

Question 7

What were the results for acoustically similiar/disimilar?

Answer 7

• in the beginning especially trail 2 recall of acoustially similar words was worse than acoustically disimilar
• they were not statistically signficant
• did not affect LTM recall

harder to recall acoustically in the intial phase suggest STM encodes acoustically

Question 8

What were the results for semantally similar/disimilar?

Answer 8

• semantically similar words were more difficult to learn than semantically disimiliar words
• Semantically similar words recalled SIGNIFICALLY FEWER in the retest

Shows LTM encods semantically

Question 9

What does it mean if memory stores get confused give an example from Baddely Study.

Answer 9

• memory stores get confused when processing infomration that’s similar
• in Baddeley’s Study, semantically similar words were harder to recall in later stage of the therefore LTM gets confused meaning LTM encodes semantically
• in Baddeley’s study acoustically similar words were harder to recal in early stage therefore STM gets confused meaning STM encodes acoustically

Question 10

How can Baddelleys Study be applicable to real life?

Answer 10

• how we can make learning more effective to be stored in LTM
• LTM encodes semantially e.g. students creating mindmaps with semantic links/knoweldge will learn more effectively then reading acoustically (STM)
• results therefore can help understand behaviour in real life and society to e.g. aid education
