LTM eval

• LTM eval strength clinical evidence

  Clinical evidence- case study of Clive Wearing is relevant here. His episodic memory was severely impaired as a consequence of amnesia and he had great difficulty remembering events that had happened in his past

  But his semantic memory was relatively unaffected e.g he still understood the meaning of words

  Furthermore, his procedural memory was still intact- Clive was a prof musician and he still knew how to read music, sing and play the piano

  This evidence supports Tulving's view that there are diff memory stores in the LTM
• LTM eval strength real life application

  Real life application- understanding types of LTM allows psychologists to help ppl with memory problems

  For e.g, as ppl age they experience memory loss specific to the episodic memory

  Belleville et al demonstrated that episodic memories could be improved in older ppl who had a mild cognitive impairment

  The trained participants performed better on a test of episodic memory after training than a control group
• LTM eval strength evidence from brain scans

  Evidence from brain scans- Tulving et al asked participants to perform various memory tasks while their brains were scanned using a PET scanner

  They found that episodic and semantic memories were both recalled from an area of the brain known as the prefrontal cortex

  The left prefrontal cortex was involved in recalling semantic memories

  Episodic memories were called from the right prefrontal cortex

  The strength of this finding is that it supports the view that there is a physical reality to the diff types of LTM, within the brain
• LTM eval limitation disagree with 3 types

  Cohen and Squire disagree with Tulving's division of LTM into three types

  They accept that procedural memories represent one type of LTM But they argue that episodic and semantic memories are stored together in one LTM store that they call declarative memory i.e memories that can be consciously recalled

  In contrast procedural memories are non-declarative
