Types of long term memory Flashcards
who discovered types of long term memory
Tulving
Who did Tulving criticise?
Atkinson and Shiffrin, he said that the multi store model was too simplistic for long term memory and there are 3 stores of ltm.
What are the three stores of ltm?
episodic, semantic, procedural
What is episodic memory?
Episodic memory is the abilty to recall events from our lives
What is procedural memory?
-memory of actions and skills without conscious awareness of much effort
What is sematic memory?
shared knowledge of world facts, memories are not time stamped
Why is episodic memory open to forgetting?
- as the memory will contain lots of elements within a single memory
Summarise HM case study
-Amnesiac patient
-studied by brenda miller and colleagues over a 50 year period
-age of 7 Hm suffered a head injury, and started having epileptic seizures
-age of 27 HM was unable to work
-surgery on his brain
-left him with severe memory problems
What did miller and colleagues conclude?
-Hm concluded that HM pattern of impairments suggested that stm ans ltm are distinct of memory and ltm has 2 distinct systems
summarise Clive wearing case study
-brain infection- damaged his hippocampus left with anterograde amnesia
-his episodic memory was impaired
-procedural memory was intact
-semantic field was intact
what does the left prefrontal recall?
semantic memories
what does the right prefrontal recall?
episodic
What does the basal ganglia?
procedural
What was Tulving evidence?
-got participants to perform memory tasks whilst in a pet scanner
Who goes against Tulving?
Cohen and squire
What are the problems with clinical evidence?
- lack of control over variables
- cannot establish cause and effect
Summarise sematic memory
-general knowledge
-in prefrontal cortex
-personal events
-limited capacity
-can both be taught
summarise procedural memory
-unconscious recall
