Types of LTM

Types of LTM

1. Episodic memories

   • Personal memories for events forming a sequence
     • Include details of context and emotion

2. Semantic memories

   • Knowledge shared by everyone abstract and concrete
     • They are acquired via episodic memories

3. Procedural memories

   • Knowing how to do something
     • They become automatic through repetition and are disrupted if you think about them

4. Evaluation

   • Brain scans
     • Episodic
       • Frontal and temporal lobe (including hippocampus)
     • Semantic
       • Temporal lobe
     • Procedural
       • Cerebellum, basal ganglia and limbic system
   • Procedural vs declarative memories
     • HM formed new procedural memories but not semantic and episodic ones
   • Brain damage evidence unreliable
     • Cant be certain that casual part of brain identifies
   • Episodic vs semantic memories can form independently
     • Double dissociation demonstrated in Alzheimers patients
   • Priming and fourth LTM
     • Perceptual representation system may be a kind of implicit memory relating to priming
