Q

evaluate episodic and semantic memory

A

S- KC (motorbike) good semantic memory poor episodic
C- Clive Wearing has a procedural memory which is neither
O/T- relies heavily on case studies, MSM is conflicting evidence
U- neuroscience also backs this theory it suggests we have different brain areas for each type of memory

Q

what is a schema

25
what is confabulation
a disturbance in memory which can lead to fabrication or a misinterpreted memory
26
emotional perception is
the ability to recognise certain emotions in others
27
Evaluate Reconstructive memory
S- the war of the ghosts, Native American story is westernised O- MSM states that we remember something through maintenance and elaborative rehearsal U- Shows us that we can't rely on one witnesses testimony as it can be influenced T- hard to test as it hard to determine how many changes people made to a story
28
what is the case study in cognitive psychology
HM
29
what is the classical study of cognitive psychology
Baddeley 1996b
30
Why did HM need surgery
he suffered severe epilepsy
31
what parts of the brain were removed from HM
Hippocampus as well as the amygdala the bilateral and medial temporal lobe
32
how was HMs memory affected
unable to produce new memories after the surgery however his LTM was fine
33
What tests were done on HM
he was asked to draw a five-pointed star in the mirror
34
what did the tests on HM show
That his procedural memory was fine, he would improve each time although having no memory of it
35
what conclusions can we make about HM
LTM has different stores and procedural memory was working fine
36
Evaluate HM
G- the information concluded for all only a case study could be generalised to the wider population as brain scans show we have similar brains A- Showed that hippocampus is a key structure in the transfer of information from STM to LTM IV- the study has low IV as it is a case study and can't be repeated E-he cant remember consenting so it raises issue of whether it is ethical
37
what was the aim of Baddeley's study
to see if LTM was different to STM as in STM it showed that acoustically similar words were impaired when trying to memorise however semantically similar words were not
38
Outline the procedure to Baddeley's study
men and women from psychology test rake part in a memory test, they were all given 4 separate lists ( making independent M ). the list appeared on a projector 1 word every 3 seconds. afterwards, they did a memory test regarding digits. then a 1-minute recall task, 15m interference and a surprise recall task follow.
39
acoustic results ( Baddeley)
acoustically words recalled worse at the start, at the end of 4 trails difference was not significant at the end
40
semantic results (Baddeley)
semantically similar words difficult to encode but are easier once in LTM
41
Overall conclusion for Baddeley
STM= acoustic | LTM=semantic
42
Evaluate Baddeley
G- only generalisable to psychology students but 72 participants were male and female R/V- High control factors A-Can be applied to learning a language Ev- low ecological validity
43
is Baddeley or Schmolck the contemporary study
Schmolck
44
What was the aim of Schmolcks study
look at the performance of SM tests and the extent temporal lobe damage and HM in comparison to other patients
45
what was the procedure in Schmolcks study
gave semantic memory test, 9 tests over the course of 3 sessions, 48 items were included eg animals and obejects
46
who were the participants in Schmolcks study
3 with medial temporal lobe damage HM- MTL damage 2- amnesia 8-'normal' participants
47
what were the results of Schmolcks study
Hippocampal formation patients ( amnesia ) able to complete tasks wheres those with MTL performed the worst, HM was one of the participants who done the worst
48
what were the conclusions of Schmolcks study
MTL sufferers had less difficulty then MTL + patients, this suggests damage to the anterolateral temporal cortex is responsible for semantic memory
49
Evaluate Schmolck
G- not representative of the whole of society R-standardized, scientific procedure, MRIs used and everyone was given same memory tests. A- helps to understand the effects of brain damage on memory E- Consent is an issue for those with memory loss
50
what is the key question for cognitive psychology
How can psychologists understanding of memory help patients with dementia
51
what is dementia?
a disease which damages someones ability to process information including memory, progressive so it gets worse over time
52
what are the symptoms of dementia
loss of memory and ability to function independently
53
how many are affected by dementia in the UK
850,000
54
How many are expected to be affected by 2025
100,000
55
How does MSM explain Dementia
Inability to transfer information from STM to LTM due to dementia
56
How does WMM explain Dementia
Declining central executive means they find it hard to pay attention to certain things
57
How does semantic and episodic memory explain dementia
Different types of memory affected this shows why someone may be able to walk and talk but not able to remember events from a long time ago
58
How does reconstructive memory explain dementia
Shows that people with dementia get their schemas confused which may lead to them getting muddled. understanding situations become harder.
59
Issues with the MSM explanation for dementia
it doesn't explain how procedural and STM memory may still work
60
Issues with the WMM explanation for dementia
Doesn't provide an explanation for the memory loss aspect of dementia
61
Issues with the Semantic and episodic explanation for dementia
Doesn't show us how some procedural memories and LTM become faded.
62
Issues with the Reconstructive memory explanation for Dementia
Doesn't explain the memory loss aspect of it.
63
What was the Cognitive practical
Can schemas improve memory recall?
64
What does our cognitive practical test
reconstructive memory
65
what design was our cognitive practical
independent measures
66
what was the method of our cognitive practical
given 3 minutes to read a short paragraph, then the two groups had to flip the paper with the paragraph over so it couldn't be seen and then it had to be written from memory. one group had a title and one group didn't
67
what was our conclusion for the cognitive practical
whether or not a title is given to an ambiguous paragraph will have no effect on someones ability to recall
68
what were the Mann Whitney U scores for group A and B for our cognitive practical
GA=without title 5.4 GB=with title 5.7 over 5% due to chance factors- reject our experimental hypothesis
