Memory

• Episodic memory is time stamped and declarative
• Semantic memory refers to memory of meanings and understanding of the world
• Semantic memories are not time stamped but are declarative
• Procedural memory is a type of memory which guides the processes we perform
• Case of Clive Wearing supports different types of LTM
• Clive’s procedural memory stayed intact but his episodic memory was severely damaged
• Clive would greet his wife as if he hadn’t seen her for years after she would leave and re-enter a room
• Brain scanning studies prove that different parts of the brain are active when performing tasks involving different types of LTM.
• There is no way to test Clive’s memory before the accident
• Hard to apply Clive wearing’s case to an entire population which is a weakness in supporting evidence for types of LTM
• In the Working Memory model there are 4 slave systems
• Central Executive allocates slave systems to tasks and has a very limited processing capacity
• Procedural memories are not time stamped and are non-declarative
• Retroactive interference - Muller gave participants a list of nonsense syllables to learn for 6 minutes then after an interval they had to recall. If participants had been given an intervening task they recalled much less. Rugby
