long term memory

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

• research: clive wearing

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.
