Types of Long Term Memory - Coggle Diagram
Types of Long Term Memory
Episodic
Specific details of the event, the context and the emotion
Personal experiences
Semantic
The meaning of different events, feelings or even the function of objects
Semantic memories may start as episodic, but over time lose their association
You still may recall when and where you learned a fact
Procedural
Implicit
Made through repetition and practice
Procedural memories need to be automatic so that we can focus our attention on other tasks

HM Case Study: could make new procedural memories, but not semantic or episodic
This is supporting evidence for the distinction between procedural and declarative memories
Hodges and Patterson (2007): Alzheimer’s patients' episodic memory more affected than semantic
Irish at al (2011): Alzheimer’s patients with the reverse – poor semantic but generally intact episodic memories
Episodic may be a gateway to semantic, but it is possible for semantic memories to form separately
It has been proposed there is a fourth kind of LTM, known as perceptual-representation system (PRS)
Spiers et al. (2001): studied memory in 147 amnesia patients - procedural and PRS memories were intact, but the declarative was affected
