1. global amnesiac

   • Amnesia
     • What is intact?
       • STM
       • Procedural/declarative(implicit memory)
     • What is damaged?
       • episodic LTM (always)
       • semantic LTM (often)
     • What is it caused by?
       • alcoholism
       • malnurishment
       • ischemic stroke
       • vitamin deficiency
       • brain trauma
         • damage to parts of the hippocampus
           • hippocampus
             • What parts of the brain are involved in memory?
               • memory works through a diffused system in the brain
           • hippocampal formation
             • episodic memory loss
           • parahippocampal region
             • semantic memory loss
   • full antegrade amnesia
   • some retrograde amnesia

2. suffered from episodic memory deficit

3. temporal lobotomy

   • removed medial temporal lobes
     • MTL are involved in linking the aspects of an event together
   • causes severe antegrade amnesia and retrograde amnesia for the last 10 years of his life(episodic memory not intact)
     • he could remember things for around one minute (STM in tact)
     • he could still speak and learn new tasks (procedural memory)
     • normal digit span
     • recency effect in tact(no primary effect)

4. K.F.

   • suffered from damage to left parietal lobe
     • no recency effect, primary effect in tact
     • damage to STM
     • normal LTM for word-lists
   • L.C.
     • normal...
       • STM
       • semantic
       • procedural
       • autobiographical
     • impaired...
       • antegrade LTM
       • visual and spatial learning
