MULTI STORE MODEL A03 Flashcards
What is one strength of the MSM (LTMVSSTM) - P
There is research support to show that the LTM and STM are different
what is an example for proof that LTM and STM are different
Baddeley found that we are more likely to mix up words when they sound similar when using our STM but we tend to mix up words with similar meaning when using our LTM.
what is the explanation for proof that LTM and STM are different
The study shows that there is a difference between the two stores and they work independently like what the MSM suggest
How many 10 word lists did Baddeley give
four 10 world lists
What were the categories of Baddeley’s lists
Acoustically similar, Acoustically dissimilar, Semantically similar, Semantically dissimilar
Where was immediate recall the worst
Acoustically similar words
Where was recall after 20 minutes the worst
Semantically dissimilar words
What is a strength for Baddeley’s coding study
identified a clear difference between the two memory stores
explanation for Baddeley’s coding study strength
The idea that STM mainly uses acoustic coding and LTM uses mainly semantic coding has remained to be the case over time
What is a limitation for Baddeley’s coding study
An artificial task was used instead of meaningful material
Explanation for the limitation of Baddeley’s coding study
The lists had no personal meanings and his findings may not be able to be applied to different memory tasks particularly meaningful ones when processing meaningful info people may use semantic coding.
What is one limitation for MSM (MTOS)
There is evidence to show that there is more than one STM store
what is an example for there is proof to show there is more than one STM store
Shallice and Warrington studied a client called KF who had Amnesia. KF’s recall for digits were bad when they were read out to him but when he read the digits to himself it was much better
What is the explanation for there is proof to show there is more than one STM store
further studies show there can be another STM store for non verbal sounds, suggesting that the MSM is wrong for claiming there is only one STM store
What is another limitation to the MSM (PRNN)
Prolonged rehearsal is not needed for a transfer to LTM
What is evidence for prolonged rehearsal is not needed for a transfer to LTM
According to the MSM the number of times you rehearse something is the most important because it makes it more likely to go to LTM. Craik and Watkins found that elaborative rehearsal is needed for LTM storage
What is the explanation for prolonged rehearsal is not needed for a transfer to LTM
If this is true information can be transferred without prolonged rehearsal and suggests that MSM does not effectively explain how LTM storage can be achieved
What was the process of Jacobs’ digit span study
researcher reads out four digits, participant recalls in the correct answer if correct the researcher adds onto the number of digits until it can’t be recalled correctly
What was the basis of Miller’s capacity theory
He saw that things in life had a pattern relating to sevens he used that for STM capacity
What is a strength of Jacobs’s study
It has been replicated
Explanation to the strength of Jacobs’s study
early studies lac adequate control and some participants’ digit span may had been underestimated because they were distracted in the study (an example of confounding variable) but the study has been replicated and it shows support for the original study
What is a limitation of Miller’s research
He may have overestimated STM capacity
What is the explanation for the limitation of Miller’s research
Nelson Cowan reviewed other research and concluded that the capacity was 4 plus or minus 1
How many students did Peterson and Peterson use
24
