Week 6 - Tuesday Flashcards
Did KC have temporally-graded retrograde amnesia?
No, his amnesia was complete. He had no memory of previous events.
Did KC have trouble making new episodic memories?
Yes.
How do we know KC’s working memory was fine?
He could do a digit span test.
What was one thing they were testing with KC in regards to the relationship between semantic memory and episodic memory?
If KC could form new semantic memories, then semantic memory is a separate system. If he couldn’t, then semantic memories grow out of episodic memory.
What was the procedure for the Long-lasting Semantic Learning test?
They’d see picture-sentence word pairs. Then fill in the blanks for a sentence.
What were the results of the Long-lasting Semantic Learning test?
KC recalled about 50% of the target words and could fill in the blanks correctly a week later. He did not remember the trials.
What was the significance of the results of the Long-lasting Semantic Learning test?
At the time, people thought it proved that semantic and episodic memories are different.
What was the procedure in the “is it semantic memory” test?
Train list of three-word phrases. Then changed the verbs with synonyms. Like cured to healed.
What were the results of the “is it semantic memory” test?
EP did much worse on the synonym test.
What was the significance of the “is it semantic memory” test?
It showed that semantic memory came from the hippocampus.
Could EP learn any new everyday semantic information, like news events?
No.
The common denominator of multiple episodic memories acquired in different contexts becomes…
Context-free semantic memory.
Out of the three patients, EP, HM, and KC, which of them were able to remember some semantic info post lesion?
KC and HM. EP could no learn any new semantic info.
Why is EP unable to form new Semantic or episodic memories, while HM and KC could form some semantic memories?
It depends on the the regions preserved in MTL. The hippocampus is important for memory, but other area are important too.
What are the MTL Structures?
PR (perirhinal cortex)
EC (entorhinal cortex)
PH (parahippocampal cortex)
Hippocampus
What brain damage did EP have?
Complete loss of MTL bilaterally.
What type of memories did EP struggle forming?
Couldn’t form new declarative memories (complete anterograde amnesia; episodic and semantic)
What type of amnesia did EP have?
Temporarily-graded retrograde amnesia.
EP was who’s patient?
Squire’s
What brain damage did HM have?
Nearly complete loss of MTL bilaterally.
What type of memories did HM struggle forming?
Nearly all Declarative memories.
What type of amnesia did HM have?
Nearly complete anterograde amnesia and temporally-graded retrograde amnesia.
HM was who’s patient?
Milner
What type of memories did KC struggle forming?
Nearly all declarative memories.
What brain damage did KC have?
Nearly complete loss of MTL bilaterally, some damage in other regions too.
What type of amnesia did KC have?
Complete retrograde amnesia for episodic memory.
KC was who’s patient?
Tulving.
What type of memory could all the patients form?
Non-declarative memory.
