What are the 3 types of LTM and are they explicit or implicit
explicit: semantic and episodic memory
implicit: procedural memory
episodic memory
this memory gives people an auto-biographical record of personal experiences.
strength of these memories are influenced by the emotions you felt at the time the memory was coded.
research: Tulving
semantic memory
contains all knowledge (facts, concepts, meanings etc)
linked to episodic memories as new memories tend to be learned from experience
overtime there will be a gadual move from episodic to semantic memory.
research: Tulving
procedural memory
skills
many procedural LTMs occur early in life

Tulving
Aim:
To explore whether episodic and semantic memory are located in different parts of the brain.
Method:
Tulving used neuroimaging (PET scans) to observe brain activity while participants (including Tulving himself) performed memory tasks.
Tasks included recalling episodic memories (personal past experiences) and semantic memories (facts and general knowledge).
Findings:
Episodic memory activated the right prefrontal cortex.
Semantic memory activated the left prefrontal cortex.
This suggests a clear distinction between the two types of memory in terms of brain location.
Conclusion:
The study supports the idea that episodic and semantic memories are stored in different areas of the brain.
