Memory- Types Of Long Term Memory

Front 1

Episodic Memory

Back 1

Personal memories of events

Hint 1

Episodes of life

Front 2

Procedural Memory

Back 2

Memory of how to do things. Memories are automatic as a result of repeated pratice

Hint 2

Skills

Front 3

Semantic Memory?

Back 3

Shared memories for facts and knowledge, memories may be concrete(ie water and ice are the same) or abstract (changing knowledge, theories)

Hint 3

Facts

Front 4

Evidence from brain scans?

Back 4

Episodic Memory - hippocampus and other parts of the temporal lobe where hippocampus is located

Semantic Memory- temporal lobe

Procedural Memory - cerebellum, Basil ganglia system

Front 5

What does HM show?

Back 5

He could form new procedural memories but not episodic or semantic memories as his hippocampus was removed but still retained his pre existing memories (so they're not located in the hippocampus). Corkin 2002 - HM was able to draw a figure by looking at then reflection. HM had no memory though of learning this

Front 6

What did Irish et al and Hodges and Peterson do?

Back 6

Hodges and Peterson studied alzhiemers disease and found some patients who retain the ability to form new episodic memories but not semantic.

Irish et al found double dissacosiations (poor semantic memories and generally good episodic).

Suggests episodic may be a gateway to semantic but impossible for semantic to form on their own.

Hint 6

Alzhiemers

Front 7

Further Evaluation

Back 7

-difficulty in study with amnesiac and cant always tell until a patient dies. A behaviour may not be caused due to the damaged area

- suggestion there is a fourth kind of LTM(prs) as priming is controlled by system separate from temporal, supporting explicit memory (semantic and episodic). Spiers el al studied memory of 147 amnesiacs, all cases showed procedural memories and prs were intact but other two systems not (implicit memory not affected by amnesia)

Hint 7

____ may not always be the cause, fourth type of LTM and priming
