Clive Wearing ­ Case Study
Clive was in a bike accident and damaged his hippocampus.
This meant he couldn't store information in his LTM as his STM was damaged.
This proves the model as it shows how the flow of memory is from left to right and
if the STM is damaged the LTM shouldn't be accessed and this was the case with
Clive.…read more

STRENGTHS
Hyde & Jenkins 1973 ­ Experiment
Participants learned a list of 24 words under different conditions.
No difference in recall was found.
However, a significant difference was found in those who were asked to judge the pleasantness of
the word.
Meaning that the thought process you have to go through to judge the pleasantness adds meaning
therefore being stored in the type II, elaborate section.…read more

Theory of Forgetting
Cue Dependent Forgetting
Failure to remember is an accessibility problem.
When we store information we also store information that occurs around it.
Tulving encoding specificity principle.
"the greater the similarity between the encoding event and the retrieval event the
greater the likelihood of recalling the original memory"
Therefore if you are in a different state/context to where the encoding event took place you
are less likely to remember, this is called cue dependent forgetting.…read more

Theory of Forgetting
Displacement
The theory of displacement can be linked with ideas in the MSM.
It is the idea that information is held for around 30 seconds in the STM.
Here it is either rehearsed so that it enters the LTM, or is lost.
Displacement as a theory of forgetting links to the rehearsal loop in the short term memory,
which has limited capacity.…read more

Studies in Detail
Craik & Tulving - LOP Experiment
Aim
The aim of the study was the test the levels of processing framework, which claimed that the best method
for recall was information that has been processed semantically. The general aim was to see if the durability
of the memory trace comes from the depth of processing.
Procedure
In the experiments participants were put into situations where they used different depths of processing.
Shallow encoding ­ they were asked questions about the script itself.…read more

Studies in Detail
Godden and Baddeley- Divers Study
Aim
Can natural environment act as a cue to recall?
Procedure
18 participants in the uni diving club asked to learn a list of 38 words, unrelated 2/3 syllable
words.
4 conditions
Learn dry land ­ recall dry land
Learn underwater ­ recall underwater
Learn dry land ­ recall underwater
Learn underwater ­ recall dry land
Results
Recall 50% higher in cue context condition.
Conclusion
Environment can act as a contextual cue for recall.…read more

Key Issue
Flashbulb Memory
Are they special? Linked with emotion
A flashbulb memory is when an event was so powerful that people see it in their memory
almost as if a photograph has been taken and can relive the event in vivid detail for a long
period of time afterwards.
Features
Vivid: potentially last a lifetime and tend to be of emotional significance.…read more
