Q

semantic encoding

A

-semantic refers to meaning
-we all know what thousands of words mean and this is because our semnatic memory is the ability to understand and use words and concepts

Q

baddley
result and conclusion

A

-similar sounding words were poorly recalled in STM, words wiht similar meaning poorly recalled in LTM
-this shows STM is encoded by sound and LTM by meaning

Q

baddley strength

A

controlled expiriment as EV like participants hearing were controlled by a hearing test enhances the validity of the expiriment

Q

baddley
weakness

A

LTM may not have bben tested as they only waited 20 mins before recall so conclusion lacks validity

Q

LTM weakness

A

its not as simple as it seems distinctice types of LTM are difficult to seperate so it may be an oversimplification

Mc Geoh + Mc Donald aim
to see what effect the 2nd activity had on the accuracy of memory
26
Mc Geoh + Mc Donald method
12 participants has to learn a list of 10 words then they were shown a new list - there were 5 different kinds of lists shown to the participants
27
Mc Geoh + Mc Donald resukt + conclusion
-when the participants were asked to recall the original list of words,thir performance depended on the nature if the 2nd list. -the results show that interfearnece is the stongest when an intervening activity is similar .
28
Mc Geoh + Mc Donald strength
controlled and unbiased = counterbalancing = high internal validity
29
Mc Geoh + Mc Donald weakness
artficial task - word list do not reflect real life memory
30
factors affectcing accuracy = context
conetxt is the general setting in which activities happen , contetx can act as a cue to recall information.
31
godden and baddley aim
to see if people who learn and are tested in the same environment will recall more infor than people who learn and are tested in a different environment
32
godden and baddley method
4 groups - 1 learned and tested on the beach - 2 learned under the water, tested on the beach - 3 learned on the beach , tested underwater - 4 learned under water and tested underwater
33
godden and baddley result + conclusion
-recall was highest in the same environment for learning and recall - context acts as a trigger or cue, improving the accuracy for memory
34
godden and baddley weakness
the test used was artificial - word lits is not a natural way to investigate recall
35
godden and baddley weakness
only applies to very similar situations
36
the multi store model
-three memory stores, different coding, capacity and duration -sensory memory = very short duration , large capacity, attention transferes info to STM - STM = limited duration and capacity, acoustic encoding - Role of rehersal = rehersla keeps info in STM, repeat rehersal transferes STM to LTM - LTM = semantoic coding , unlimited capacity and stored yp to a lifetime
37
capacity
amount of info taht can be stored in the meory store
38
sensory
- less that 1 sec - capacity very high
39
short term
- less than 1 min - about 7 chunks
40
long term
- up to a lifetime - capacity unlimited
41
MSM strength
there is evidence to support the existance of differet memory stores so baddleys research supprts the view
42
MSM weakness
having 1 stm and ltm store is too simplisitic
43
primacy effect
these words were tyhe first heards - they have been rehearsed, so we can recall form our ltm
44
recency effect
these words were the most recently heard so we cfan recall because its still in our stm
45
Murdock aim
to see if to see if memory of words were affected by the number of words a person ahs to remember
46
murdock method
- rnadomly selected 4000 most common words in the dictiniary , 103 students form psychology cource took part in the study - 20 word list which ecah contained diff words- lists varied in lengths form 10 - 40 words
47
murdock result + conclusion
-recall related to position of words, higher recall for the first words and last words than the ones in the middle -shows the serial position effect and supports the MSM stores
48
murdock strength
was conducted in a highly controlled environment which makes the results more valid
49
murdock weakness
the word list only represents a small part of what we do with our memory so lacks external validity
50
false memory
memory for somehting that did noit happen but feels as if it were a true memory
51
loftus and pickrell aim
to see if false memory could be created in participants through suggestion
52
loftus and pickrell method
24 participants were given short stories about childhood from relatives. 3 3 were true and 1 was getting lost in a mall amd getting rescued by an elderly lady
53
loftus and pickrell result + cocnclusion
- 6 out of 24 recalled the false story fully or partially - imagining an event can implant a false memory in a person , reducing accuracy of memory
54
loftus and pickrell strength
it has important implifications for eye witness testimonies - police may unconsiously ask leading or biased questions to person
55
loftus and pickrell weakness
there are ehtical issues - at the end the participants were given a debrief - they bwere told its fake but they still left wiht an unpleasant feeling
56
bartletts war of the ghosts
altering our recollection of something so that it makes more sence to us
57
bartlette aim
to see how memory is reconstructed when people are asked to recall somwthing over a period of days or months
58
bartlette method
the war of the ghoss story was read by 1 participant amnd was recalled after 15 minutes then read by another participant and so on
59
bartlette results + conclusion
- participants changes the story to fit cultural expextation and left out unfamiliar information - we use our knowledge of social situations to reconstruct memory
60
bartlette weakness
it was conducted casually wiht no set standards about whereand how people recalled the information thus it lacked control - the recall was probably more accurate because 9of the lack of control
61
bartlette weakness
-the study was unusual and may noit reflect everyday memory process -therefore this study may only mtell us little about everyday memory as it kacks ecological validity
62
reconstructicve memory
fragments of stored information are reassembled during recall, the gaps are fulled in by our expectations and beliefs so that we can produce a story that makes sence to us. - we store fragments and when we want to recall it we build there fragments into a whole - elements are missing that means memories are less accurate -
63
reconstructicve memory social and cultural influences
expectations come form the world and culture we live in and affect storage and recall
64
reconstructicve memory effort after meaning
we focus on meanings of events and make an effort afrerwards to make sence of fragments or memory
65
reconstructicve memory strength
- it has real world applications - can be used to explain problems wiht eye witness testimonies
66
reconstructicve memory strength
this study refletcs how we actually use memory in everyday life, more realestic than using word lists to test people
67
reconstructicve memory weakness
not all recall is reconstructed as some memories of the story are accurate
