LONG TERM MEMORY

• How many types of LTM are there?

  3
• what are the 3 types of LTM?

  Episodic memory

  semantic memory

  procedural memory
• Which 2 memory stores are explicit?

  semantic and episodic
• which memory store is implicit?

  procedural
• what is explicit memory?

  conscious memoru
• what is implicit memory?

  unconscious memory, automatic
• What does episodic memory do?

  stores events (episodes) from our lives eg. personal experiences and events
• are episodic memories time stamped?

  yes - you remember when they happened and how they relate in time
• episodic memories are complex, they involve several elements - people, places, objects and behaviours are woven into one memory
• what does semantic memory do?

  stores general knowledge and facts eg.meaning of words, taste of things
• are semantic memories time stamped?

  no - they are less personal than episodic and more about facts/knowledge that we all share
• what does procedural memory do?


  stores memories of how we do things eg. riding a bike or writing
• Strength for different types of LTM

  case study evidence - HM didn't have episodic memory but semantic memory was still intact same with procedural

  COUNTERPOINT

  researchers lack control in clinical case studies - they don't know about the person's memory before brain damage
• Limitation of different types of LTM

  conflicting findings-

  Buckner and Petersen reviewed research findings and concluded that semantic memory is located in the left prefrontal cortex with episodic on the right

  BUT other studies have found that semantic people was associated with the right prefrontal cortex and episodic was the left
• what did Belleville et al do?

  Helping people with memory problems

  memory loss in old age links to episodic memory, devised an intervention for older people targeting episodic memory, which improved their memory compared to the control group
