Week 4 - Thursday Flashcards
What disorder did HM have?
He had anterograde amnesia.
What is anterograde amensia?
Can’t form new explicit memories.
What did the case of HM show us about memory?
The hippocampus and other structures in the medial temporal lobe are critical for making new memories.
Were HM’s procedural memories intanct?
Yes, they were intact.
HM also suffered from _____________ retrograde amnesia.
Temporally graded.
Can procedural memories be retrieved through a retrieval cue?
No. You must do the task to remember it.
Procedural memory is also called?
Nondeclarative memory.
What are some tests of procedural memory?
- Mirror drawing task
- Repetition priming.
What happened when HM tried to mirror-drawing task?
He improved with repeated training. But he could not remember doing it.
What was the significance of HM doing better at the Mirror Drawing Task?
It showed his procedural memory was intact, and his explicit memory was damaged.
What does HM completing the drawing test say about the hippocampus?
Procedural memory do not involve the hippocampus.
What happens on a repetition priming test?
Examine a list of words, then fill in the blanks
Pr_ ce_ _ (process)
Did HM have an explicit memory of the repetition priming test?
No.
What happens if you change the orientation of triangle on the Visual Search test?
Participants won’t do as well, even if they practiced it, because they learned it with one orientation.
Was H.M. able to improve on the visual search test?
Yes.
What’s one thing the Visual Search Test shows about procedural memory?
Improved ability to detect one target does not transfer to another target (learning is extremely specific)
What does it mean that HM had temporally graded retrograde amnesia?
He lost memory for some events preceding the lesion.
What are the implications of how the hippocampus works, in regards to temporally graded amnesia?
The hippocampus plays a role in consolidating memories in the cortex for some period of time after the memory is first formed.
