Long-term Memory (Tulving)
Episodic Memory
Remembered experiences
Memories are linked to particular time or date
Input of the memory is continuous
Recall is dependent on the context in which it was learnt e.g. wedding.
Forgetting is more likely as the memory can be changed or sometimes we forget when we don't have the right cue.
Semantic Memory
Remembered facts
Memories are not linked to specific time
Input of the memory can occur in fragments and input at different points in time.
Recall isn't dependent on the context in which it was learnt.
Forgetting is less likely as the memory trace is robust and less susceptible to transformation.
Brain damaged patients case studies
Clive Wearing
Remembers the fact that Deborah is his wife and that he loves her.
However has forgotten any events and experiences he had with her.
Their wedding day.
HM
Couldn't recall events from his past e.g. he had a dog.
Didn't need concept of a dog explained to him.
Studies provide evidence for there being two different types of memory in different parts of the brain.
Episodic memory cannot exist without semantic memory
You don't need episodic for semantic memory because semantic exists on its own.
Alzheimer's patients
Episodic memory is affected first and then later on patients start to lose knowledge from semantic.
Supports LTM because memory deteriorates in stages showing there are different types of memory as one type of memory is damaged first then the rest deteriorates .
Evaluation
Too simplistic as there are only two types of memory.
Has alot of evidence from case studies which makes theory credible.
