Episodic memories are stored with reference to the time and place where they occurred
Episodic memory refers to personal memories of events, such as what you did yesterday. This kind of memory includes the contextual detail plus emotional tone
Procedural memory refers to memory for how to do things. Such memories are automatic as the result of repeated practice.
Semantic memory is facts and knowledge. These memories may be concrete
Semantic memories generally begin as episodic as we acquire knowledge based on personal experience
Procedural memory is typically acquired through repetition and practice as we are less aware of these memories
Declarative memory is knowing 'this' as opposed to 'how'
