MEMORY- Types of LTM Flashcards
Define episodic memory
A LTM store for personal events, it involves memories of when the events occurred and of the people, behaviours, objects and places involved
Define semantic memory
An LTM store for our knowledge of the world, this includes facts and our knowledge of what words and concepts mean
Define procedural memory
An LTM store for our knowledge of how to do things which includes our memories of learnt skills
What did Tulving (1985) argue?
-MSM is too simplistic + inflexible
-Believed that there were 3 different stores for different types of information
What were declarative memories?
-Semantic memories
-Episodic memories
What is a flashbulb memory?
A detailed and vivid memory of an event that is stored after the occasion and lasts a lifetime
Give some examples of flashbulb memories
-Births
-Deaths
-Things associated with important historical events such as 9/11
What makes a flashbulb memory particularly vivid?
-Emotional arousal when the memory is first encoded
What type of memories are episodic and semantic? Why?
Explicit- you consciously remember
What type of memory is procedural? Why?
Implicit- you unconsciously remember
Give an example of an episodic memory?
-Birthday
How do semantic memories usually start?
-Episodic memories but progressively loose their association with particular events and only the knowledge remains
Give an example of a procedural memory
-Riding a bike/driving
Are procedural memories automatic after repetition and practice
Yes
Give a strength (neuro imaging)
-Evidence from brain scans
-Episodic memory is associated with the hippocampus, other parts of the temporal lobe and frontal lobe
-Semantic memory relies on the temporal lobe
-Procedural memory activation is associated with cerebellum
-Indicates that three types of memory are found in different part of the brain so are separate
-Physical evidence= valid
Give another strength (clinical evidence)
-Clinical evidence
-Both Clive wearing and HM suffered from LTM memory loss due to brain trauma
-Their episodic memory was impacted but semantic memory remained intact as Clive could still read music
-If there were not different types of LTM the men would have no long term memories at all
-However studying participants will brain injuries lacks control variables which prevents the researcher from being able to generalise
Give a strength (Alzheimers)
-Studies of patients with Alzheimer’s
-Researchers examined the relationship between episodic and semantic memories
-Some patients could form new semantic memories but not new episodic memories (Hodges and Patterson 2007)
-Irish found that some Alzeimhers patients had poor semantic memory but generally intact episodic memories
-Suggests that episodic and semantic are separate
-Episodic memories may be a gateway to semantic memory
-Semantic memories may form separately
Give a limitation (declarative memory)
-Declarative memory
-Cohen and Squire(1980) disagree with the division of the LTM into three types
-.They argued that episodic and semantic memories are stored together in one LTM store (declarative memory)
