types of LTM

Cards (8)

  • episodic memory is an ltm store for personal events and experiences
  • semantic memory is a long term memory store for knowledge of the world around us
  • procedural memory is a long term memory store for knowledge of how to do things
  • Outline two ways episodic memories are different from semantic
    Episodic is memory of personal experiences and specific events in one's life (first day at college) whereas semantic refers to general knowledge and facts about the world (Paris)Episodic memory is time stamped meaning it involves specific moments ties to particular contexts in time, semantic isn't time stamped as it relates to facts or concepts that are known without reference to when or where they were learned
  • Episodic memory - hippocampus 
    Semantic memory - temporal/frontal lobes 
    Procedural memory - cerebellum/motor cortex 
  • supporting evidence based on case studies of brain damage individuals that suggest that episodic memories and semantic memories are different. Vicari et al: Case study of an 8 year old girl who suffered brain damage following the removal of a tumour. Due to the location of the damage, she found it difficult to create new episodic memories, but was still able to make some semantic memories. This suggests that episodic and semantic memories are separate types of LTM and are associated with different locations of the brain
  • supportive evidence for the types of LTM - Patient HM and Clive Wearing - both men had damaged episodic memory due to accidents but their semantic and procedural memories were unaffected - Clive could still play the piano but couldn't remember marring his wife
  • supportive evidence for types of LTM - Tulving et al (1994) got their participants to complete memory tasks as their brains were being scanned using a PET scanner.It showed that episodic and semantic memories were both recalled from an area called the prefrontal cortex which is divided into two (left and right hemisphere) left -semantic memories and right-episodic memories. - shows memories are stored in different parts of the brain
