classic study- baddeley working memeory model Flashcards
when describing a study what must you include
aim, procedure,findings and conclusions
what was the aim of baddeleys study
to see if ltm was like stm, if ltm acoustic similarity of words would lead to more memory impairment
what was the method of this study
- lab experiment
-independent measure
iv was the types of word list that was given
do was the recall of the order of word lists
how did this research influence psychology
it shows the importance of experimental design, since is uses both independent groups and repeated measures
what was the background for this study
stm for word sequences is impaired for acousitcally similar words but not for semantically similar words
who was in experiment 3
mixed men and women approx 20 per group
what was in experiment 3
4 lists
when was this experiment 3 performed
1966
where did the study take place
in a lab, applied psychology research unit, Cambridge
how- experiment 3
4 lists per group- acousitcally similar and dissimilar , semantically similar and dissimilar
what was the method for experiment 3
1- presented with word list (10 words for 3 seconds )
2- digit task
3- test (write down the word list in the correct order)
4- 15 min digit copying task
5- surprise recall
what were the results for experiment 3
acoustically similar list showed no significant difference
semantically similar list the control lost was significantly better for recall
what were the findings of experiment 3
trial 1 and 2 - harder to learn list of acoustically similar words as Stm trying to hold the information
trial 3 and 4 the words are being transferred into ltm so the % recalled becomes similar
retest condition- words have been transferred into the ltm so no difference in recALL BETWEEN trial 4 and the retest
experiment 3 conclusion
learning of word sequences impaired by semantic similarity
ltm based on semantic encoding and stm based on acoustic encoding
