Types of LTM

• What are the 3 types of LTM?

  Episodic, semantic and procedural
• Episodic and semantic memory are both declarative memory (conscious)
• Procedural memory is unconscious
• Episodic LTM is the memory for events
• Semantic LTM is the memory for facts and general knowledge
• Procedural LTM is the memory for skills
• In terms of LTM - H.M study

  episodic was impaired (he couldnt remember meeting Brenda Milner many times since his operation)
• In terms of LTM - H.M study

  procedural remained intact (was successfully taught how to mirror-draw)
• In terms of LTM - H.M study

  HM couldnt form new semantic memories (didnt know what a jacuzzi was) - Gabrielli et al
• Evaluation of HM

  the case was pivotal in discovering distinction between episodic and procedural LTM
• Evaluation of HM

  It's unclear whether the case of HM can be generalised due to his unusual circumstance
• Evaluation of HM

  the case cant be replicated so unclear whether results are reliable.

  Clive Wearing also demonstrate distinction between episodic and procedural LTM.

  • had severely impaired episodic memory
  • functioning procedural memory
• Research evidence - Tulving

  aim: to investigate the possible differences in the processing of episodic and semantic memory tasks
