types of LTM

• Semantic memory


  Our knowledge about the world, facts and concepts
• Episodic memory


  Our memories for particular events in our lives
• Procedural memory


  An unconscious memory of skills, known as muscle memory
• Declarative memories are episodic and semantic memories that can be recalled consciously
• Non-declarative memories are procedural memories that can be performed unconsciously
• Episodic memories


  Are associated with a particular time and place
• Semantic memories


  Are not associated with a particular time and place
• Procedural memories


  Are not associated with a particular time and place
• Episodic memories


  Can be easily forgotten
• Semantic memories


  Are more resistant to forgetting
• Procedural memories


  Are very resistant to forgetting
• Episodic memories


  Are influenced by the level of emotion felt during encoding
• Semantic memories


  Are influenced by how deeply the information is processed
• Procedural memories


  Are influenced by the amount of practice
• Brain regions associated with different memory types

  • Episodic - Prefrontal cortex and hippocampus
  • Semantic - Parahippocampal cortices
  • Procedural - Motor cortex and cerebellum
• Research on amnesiac patients suggests episodic, semantic and procedural memories are separate processes
• Modern cognitive neuroscience studies also show distinctions between the types of long-term memory
• However, there are some connections between the different types of long-term memory
