Explanation Of Long Term Memory Flashcards
What is episodic memory
Personal memory of events. Type of explicit memory. Includes details of the event. Encodes via smells sound and now it is experienced. Includes when and where
What is procedural memory
Memory of how to do things. Implicit memory. Hard to explain
What is the time referencing of episodic memory
Dependant on time referencing memories about events that have happened are linked to the time that they occurs
What is the time referencing of semantic memory
Not linked in this wag you can recall without knowing when it happened
What is the spatial referencing of episodic memory
Is continuous as we experience a whole episode in some temporal frame of reference
What is the spatial referencing of semantic memory
Learnt in a fragmented way. Can be stored seperately and pierced together later
What is the retrieval of episodic memory
Dependant on the context. This context aids the retrieval of memory. Retrieval changes the memory as you link new information to it. The new episode links to old memories
What is the retrieval of semantic memory
Not dependant on the context in which it was learned. Based on generalisation and logical thought. New semantic memories dues to not change the original. New memories can be made in light of new information
Are the stores interrelated
Semantic memory can operate independently of episodic memory
Episodic memory in inlikely to operate without semantic memory as we need to draw on previous knowledge
Strengths of explanation of long term memory
DR S BUTTERWORTH suffered a skiing fall, lost 25 years of episodic memory but could still recall his facts of doctors and could still ski
HEINDEL ET AL investigated Huntingdons disease no problems lesrning new facts but had severe problems lesrning new motor skills
TULVING performed 6 brains scans and found when using episodic memory the frontal lobes were active compared to semantic memory when the back cortex was active
SQUIRE AND KANDEL cerebellum is important in earlier stages and necessary for coordinating the specific repeat of movement and organising the timing of movements
Weaknesses of long term memory explanation
TULVING described but doesn’t explain the differences of the memories
MEDIAL TEMPORAL LOBE used for semantic and episodic so not much evidence for seperate stores
What is semantic memory
Memory for facts and knowledge
Type of explicit memory may start as episodic but over time may lose their association. So only knowledge stays. About concepts unrelated to the person
