  • Non-Declarative
    Memories aren't consciously recalled, difficult to express in words
  • Episodic Memory

    Experiences and events
    • Time Stamped
    • Declarative
    • Strength of the memory influenced by emotion
    • Linked to hippocampus and prefrontal cortex
  • Semantic Memory

    Facts, meanings and knowledge
    • Declarative
    • Strength of memory from processing in depth
    • Linked to perirhinal cortex
  • Procedural Memory

    Unconscious memory of skills
    • Non-Declarative
    • More resistant to forgetting
    • Linked to the motor cortex and cerebellum
  • (+) A03: Vargha-Khadem
    Found children with damaged hippocampus, but not parahippocampal cortices, had episodic amnesia but could recall facts, suggesting different LTM stores
  • (+) A03: Clive Wearing
    CW has Retrograde Amnesia, being unable to recall episode events, but can remember semantic and procedural e.g. marriage and playing piano
    Due to Anterograde Amnesia, can't form new memories but can learn new skills, suggesting different LTM stores
  • (-) A03: Ideographic Research Support

    Cannot generalise ideographic research from case studies to wider populations as there could be other factors causing these changes
  • (-) A03: Cohen + Squire
    Argue that due to both being declarative, Episodic and Semantic longterm memory is stored in the same place
