Cognitive Study: Baddeley Flashcards
What was the aim of Baddeley’s study?
He conducted a study that showed recall of acoustically similar words from short-term memory was poor. However the short term memory was not affected by semantically similar words. We aim to apply the same procedure to see if it was the same for long-term memory.
What year did Baddeley do his study?
1966
What type of experiment and group design was baddeleys study?
Lab experiment using independent group design
How many participants were there and where were they from? What thpe of sample?
72 participants and they were from Cambridge University it was a volunteer sample.
What screenings did he do beforehand?
A hearing test was given before the procedure excluding three participants. 
Describe the procedure. Baddeley
Is there a full list of 10 words: acoustically similar, acoustically dissimilar, semantically similar, semantically dissimilar. The words presented aloud on a tape with one word every three seconds. They had 40 seconds to remember the order of the words. Then were given an unexpected intervention for 20 minutes. Afterwards they had to record the 10 words again.
Describe the findings of Baddeley.
Short-term memory of the acoustically similar list had a lower mean score. 20 minutes later the long-term memory had no significant forgetting of acoustically similar words although there was in acoustically dissimilar.
What was the conclusion of baddeleys study?
The long-term memory is acoustic and the short-term memory is semantic.
Evaluate Baddeley G
Although there was a large sample of 72 meaning anomalies would be averaged out there were so many conditions for each group had only 15 to 20 people meaning anomalies could affect the data.
Evaluate Baddeley R
The reliability of this study is good because you standardise procedures. For example, each participant saw the word for three seconds. He also avoided read aloud word list so ppts with hearing difficulties wouldn’t be at a disadvantage.
Evaluate Baddeley A
Baddeleys study Helps us with revision techniques. For example, if long-term memory encode semantically students should use mind maps with semantic links like images.
Evaluate Baddeley V
Badly study has low ecological validity because recalling the order of the word list is an artificial behaviour. However he did improve this with a surprise factor as you’re often asked to recall information unexpectedly.
