List 2 ways semantic and episodic memories are different
They are functionally different:
1) Different types of information
2) Different experiences
Describe the neuropsychological evidence supporting the claim that semantic and episodic memory systems are different
List 3 points
1) Spiers, Maguire, and Burgess (2001) —-> 147 cases of amnesia
2) Substantial or even dramatic loss of episodic memory
3) Semantic memory effects more variable and generally smaller

Severe loss of concept knowledge but intact episodic memory (and intact cognitive abilities)
This is known as…?
Semantic Dementia
Semantic Dementia patients have damage to 2 regions in the brain
What are they?
1) Anterior frontal lobes
2) Anterior temporal lobes
Damaged anterior frontal and anterior temporal lobes
Patients with these damages are diagnosed with…?
Semantic Dementia
Impaired access to facts and knowledge about the world
This is known as…?
Semantic deficit
What is semantic deficit?
Impaired access to facts and knowledge about the world
Inability to store new personal event and/or access to episodic detail. To somebody’s past
This is known as…?
Episodic deficit
What is episodic deficit?
Inability to store new personal event and/or access to episodic detail. To somebody’s past
Semantic deficit is affected by damages to 2 regions of the brain
What are they?
1) Anterior frontal lobe
2) Anterior temporal lobe
Episodic deficit is affected by damages to 2 regions of the brain
What are they?
1) Hippocampus
2) Medial temporal lobe
Are Episodic and Semantic memory systems …?
a. Codependent
b. Independent
b. Independent
True or False?
Many long-term memories consist of only episodic memories
False
Many long-term memories consist of a mixture of episodic and semantic aspects
True or False?
Episodic and Semantic memory dynamically interact and affect each other
True
Chunking and organising the elements of a long list of items (numbers in this case) may lead to worse encoding
True or False?
False
Chunking and organising the elements of a long list of items (numbers in this case) may lead to better encoding
Who investigated the recall of complex materials (e.g., drawings and folk tales)?
Bartlett
Who examined recall errors?
Bartlett
Unlike Ebbinghaus, Bartlett stressed participants’ …?
Effort after meaning
Who stressed participants’ effort after meaning?
Bartlett
Who gave meaning to studied materials as a better way of organising thought and eventually memory?
Bartlett
Bartlett gave meaning to studied materials as a …?
Better way of organising thought and eventually memory
Rather than study the gradual accumulation of information over successive learning trials, what did Bartlett prefer to do?
He preferred to use the errors that his participants made as a clue to the way in which they were encoding and storing the material
Define Schemas
Structured representation of knowledge about the world, events, people or actions
AKA = A longterm structured representation of knowledge that was used by the rememberer to make sense of new material and subsequently store and recall it

This is known as…?
Schemas

Describe the results of Bartlett’s War of the Ghosts experiment
The War of the Ghosts (Native American folk tales), in which several features were incompatible with European expectations (or those of Americans unfamiliar with the North American Indian culture).
Hence, the supernatural aspect of the story was often omitted and people committed many errors and distortions when they asked
to recall these
In their recall made the story more coherent and omitted details
In Bartlett’s War of the Ghosts experiment, people made the story more coherent and omitted details when asked to recall the story
These distortions were more consistent with …?
Their own semantic knowledge
Simply = Features of the story that were puzzling to the readers were rationalised by distorting them to fit their expectations
In Bartlett’s War of the Ghosts study, recalled stories from people were…?
Westernised
What was one of the criticisms of Bartlett’s War of the Ghosts study?
He provided vague instructions to the Ps
