Long Term Memory Flashcards
What are 3 ways of testing LTM?
Free-recall, Cued recall, Recognition task
What concept did Cantor et al 2014 come up with?
Marginal knowledge- can only be retrieved with appropriate memory cue
What did Brown and McNeil study?
Tip-of-the-Tongue Phenomenon. PPs were given definitions to low-freq words. Attempt to recall words associated with the definition
What is the War of the Ghosts study by Bartlett 1932?
Memories shaped to conform to our personal beliefs. Memories recalled aren’t copies, but reconstructions.
What did Loftus and Palmer find?
The speed of the car was influenced by the verb used and the use of a direct question
What did Godden and Baddeley study?
Context cues. Deep sea divers
What do we forget LTM’s?
Lack of encoding
What is the difference between proactive and retroactive interference?
Proactive - previous info impairs ability to learn new info
Retroactive - New info impairs the ability to recall old info
Describe what happened to HM and Clive Wearing
HM- Had hippocampus removed, memory was poor for events post op
Clive Wearing- Had long case of amnesia. Cannot form new memories and recall aspects of the past. Wakes up every 20 seconds. No knowledge of learning music but can still play the piano
What is Korsakoff syndrome?
Alcohol-related problem. Leads to brain damage in the hippocampus and diencephalon (loss in episodic memory). Gradual onset but widespread damage
What is the difference between retrograde and anterograde amnesia?
Retrograde- Affects episodic memories. Damage to cortical and neocortical structures. Inability to recall events from before incident.
Anterograde- Problems with consolidating memories. Could be caused by damage to subcortical areas. Inability to form new memories since critical event.
What is Nadal & Mosovith’s Multiple Trace Theory?
Argues consolidation is important but so is retrieval. Consolidation creates multiple traces of a memory in the brain. Damage to hippocampus can remove some traces
What is Perceptual Priming?
Word identification under fast exposure. Amnesics showed typical priming effect, even though much worse explicit memory from prime list words
How did Schacter test procedural memory in Amnesiacs?
Tested amnesiacs in a natural golf setting. Memory of events were impaired. However, played golf with a substantial degree of skill- old skills were perserved.
What was demonstrated in the mirror-learning task?
Amnesiacs had a slower learning rate and learning was less flexible. Patients do not remember doing the tasks each day.
