- Episodic and Semantic Memory
- LTM is divided into 2 stores
- Episodic
- Remembered experiences
- Semantic
- Remembered facts
- Dissociation is based on evidence that each store was different in terms of the nature of stored memories
- Episodic
- The nature of Semantic and Episodic memory
- Semantic memory is represented as a mental encyclopedia, storing words, facts, rules and meanings as an organised body of knowledge
- Memories are associated with other facts that link concepts together without association
- Episodic memory is represented as a mental diary
- It receives and stores information about experiences or events that occur at a time in our life
- Linked by time and context
- It receives and stores information about experiences or events that occur at a time in our life
- Semantic memory is represented as a mental encyclopedia, storing words, facts, rules and meanings as an organised body of knowledge
- Time referencing
- Episodic memory is dependent on time referencing
- Memories about events that happened to you are linked to the date the event occured
- Semantic memory is detached from any temporal link as factual info could be recalled without reference to when it was learned
- Episodic memory is dependent on time referencing
- Spatial referencing
- Episodic memory is continuous
- Semantic memories are input in a fragmentary way
- Retrieval
- Recall of episodic memory is dependent of the context in which the event was learned or experienced
- Semantic memory does not seem to be dependent on the context in which it is learned
- Retrieval from semantic memory can be based on interferences, generalisation and rational, logical thought
- Retrieval from semantic memory leaves the memory trace relatively unchanged from its original form
- Are the stores interrelated?
- Semantic memory can operate independently of episodic memory
- Episodic memory is unlikely to function without semantic memory
- Evaluation
- Brain Damage
- Evidence for the dissociation between semantic and episodic memory suggests that one store can be affected without affecting the other one
- Case study of a 10 year old boy who had an anoxic episode
- His intelligence remained intact but he suffered impairment to his episodic and semantic memory
- He did make educational progress and was able to store information in the semantic memory
- Examining case studies of brain-damaged patients also points out a weakness in the model of long term memory proposed by Tulving
- His intelligence remained intact but he suffered impairment to his episodic and semantic memory
- Case study of KC who had a serious bike accident
- Suffered specific short term memory impairment
- Resulted in inability to form or recall personal events in his life
- His recollection of facts was intact
- Supports distinction between the two long term memory stores and indicates possible regions of the brain where the different types of memory are stored
