Baddeley 1966 (B Experiment)
Cards in this deck (15)
- 1What did previous research show?That STM isn't as accurate when words given are acoustically similar. Words that were semantically similar were remembered better.
- 2What happened in Baddeley's experiment 1?20 participants were split into 4 groups and given 4 trials of the same word list, then distracted and asked to recall words in order. Acoustic was remembered best, suggesting information was in the STM still as it is known STM works acoustically. Baddeley wanted words to be in LTM so did experiment 2.
- 3What was the aim of Baddeley?To see if in the long term memory acoustically similar words would be recalled with less accuracy than semantically similar words.
- 4What procedure was Baddeley's experiment?A lab experiment with independent measures
- 5What were the IV and the DV of the study?The IV was the type of word list given (whether it was semantically similar, acoustically similar or a control).
The DV was whether the participant could recall the order of the words (wasn't how many words could be remembered but the order) - 6Who did the sample consist of?Males and female selected from the 'Applied Psychology Research Unit'
- 7What was the procedure?The words were projected before the participants at the rate of one word every three seconds. They then underwent distraction tasks and were eventually asked to write down the original words in order. This was repeated over 4 learning trials to transfer to LTM. After all trails, P's were given the words in a random order and asked to put them in the correct order
- 8Why were they given interference tasks?To stop any acoustic rehearsal
- 9Why did they have to repeat the task 4 times?To transfer the information into the long term memory
- 10What is the generalisability of Baddeley?The sample size and the fact they were selected from a Psychology Centre would normally decrease generalisability, but we say memory works in one universal way so it should still be applicable to the general population even if there was a small sample size
- 11How is the reliability of Baddeley et al?High in reliability as there is consistency between other findings such as those of Underwood and Goad.
- 12What is the application of Baddeley?Helps students in education as it suggests learning of items is improved by semantic similarity, which can help devise techniques for students to learn such as not grouping together similar topics as they get confused in the long term memory.
- 13What is the validity of Baddeley?High in internal as it was a lab experiment which controlled the IV and DV strictly, but it's low in mundane realism as the task was not valid to every day life and it was low in external validity as P's were out of their every day setting.
- 14Ethics of Baddeley's study?The surprise recall task was not consented to by the P's so fully informed consent wasn't gathered, hence P's were deceived but this was necessary for the accurate findings.
- 15What happened in experiment 2?Housewives were given acoustically and semantically similar lists. The first group did the same procedure as in experiment 1, the second were distracted before the test and the third was distracted after the test as a control. Distracting before the test worked best.
