Long- Term Memory Structure Flashcards
What are the first two sub-categories of long-term memory?
Explicit and Implicit
What is the difference between implicit and explicit memory?
Explicit: conscious memories
Implicit: unconscious
Explicit memory contains?
Episodic: events and experiences (mental time travel)
Semantic: facts about the world
Implicit Memory contains:
Priming
Procedural:
Conditioning:
Name 4 types of priming
Repetition (same as target: doctor primes doctor)
Conceptual (semantically related: husband primes wife)
Perceptual (similar in stimulus form: planet/baseball
Response (similar to target response)
Procedural memory is
skills, usually unconscious (sometimes easier if not actively thinking about it)
Conditioning memory
when a neutral stimulus becomes associated with a conditioning stimulus. Pavlov/bell is the conditioned response
What did the removal of the entire hippocampus result in for HM and what did it prove about STM?
Couldn’t form new LTMs
STM intact
Hippocampus not involved in STM
What happened to CW when he contracted encephalitis?
Damage to the hippocampus (need for LTM)
Couldn’t form new long-term memories. Memories last about 1min.
Keeps feeling like he just woke up.
K.F damaged his parietal lobe and what happened?
issues with STM.
Digit span of 2
Had reduced recency affect
Primacy effect was ok (1st numbers)
LTM unaffected, could form new memories.
KC damaged his hippocampus in an accident. What happened?
No episodic memory
Still has semantic memory, but no episodic component
Episodic and Semantic Memory are both part of explicit long-term memory, so they are represented in the same part of the brain. T/F?
False!
The double disassociation with KC and the Italian women shows that they are in different areas.
LTM is anything that was longer than
30sec ago or something in active rehearsal
Serial position curves show
that early and late words in a sequence are more easily recalled
Primacy and Recency effect
Visual coding is part of
both LTM and ST
