- Semantic Memory: structured record of facts, meanings, concepts and knowledge about the external world
- Episodic Memory: stored information about events that we have experienced in our lives
- Procedural Memory: involves the knowledge of knowing how to do things (memory of motor skills)
- Time Referencing: believed that episodic memory was dependent on time referencing: memories about events that happened to you are linked to the time in which they occurred, applies to episodic memories as the memory is linked to the date in which it took place
- Spatial Referencing: episodic memory is continuous as we experience the event at one time in some temporal frame of reference, whereas semantic memory is fragments of different pieces of information learnt at different points of time
- Retrieval: episodic memory can be contextual, meaning that people can have different interpretations of the same event and would therefore have different memories of it, whereas semantic memories are factual and therefore cannot be disputed
- Semantic memories can act independently of episodic memories, however we need semantic memories to assist episodic memories as they help with facts such as objects, people, and events that occurred
- Both semantic and episodic are declarative and rely of the medial temporal lobe, whereas procedural memory is non-declarative and does not require the revelation of memories
- Declarative memory is highly flexible, involving the association of multiple pieces of information into a unified memory of representation
- Semantic memory mainly activates the frontal and temporal cortexes whereas episodic memory activity is concentrated in the hippocampus initially
