- The types of long-term memory
- Episodic memory - they are the personal memories which involve specific details, context, and emotion.
- I remember revising for my A levels - I was not happy!
- The hippocampus, the temporal lobe, and the frontal lobe are all activated when an episodic memory memory is created or recalled.
- Procedural memories - they are the memories for how you do things and are concerned with skills.
- Example: In an exam you have to write longhand, but I know how to type much faster on a computer.
- The cerebellum, the motor cortex, and the basal ganglia and limbic system are all activated when a procedural memory is made created or recalled.
- Semantic memory - they generally start as an episodic memory, but are there's a gradual transition from episodic to semantic memory where the memory loses its association with a particular event or emotion.
- Example: I know many theories and studies in psychology.
- The evaluation points...
- HM case study.
- His hippocampus was removed. He was able to create new procedural memories after the removal of the hippocampus, but not episodic or semantic memories.
- He was able to learn how to draw a figure by looking in a mirror reflection, a skill called mirror drawing. This is a procedural memory. However, he had no memory that he had learned this (no episodic or semantic memory).
- This supports the idea that there are different types of LTM.

- Evidence from patients with brain damage.
- The difficulty with studying amnesiacs is that it is difficult to be certain of the exact parts of the brain that have been affected until a patient has died. Most studies are conducted with living patients. Damage to a particular area of the brain of the brain does not necessarily mean that area is responsible for a particular behaviour - it may be acting as a relay station. Malfunction of the relay station would impair performance.
