Unit 6: Structure of Long-Term Memory
What is LTM
archive of information about past events and knowledge learned
work closely with working memory
Korsakoff's Syndrome
chronic alcoholism
unable to form new LTM
anterograde amnesia
Coding in LTM
predominant coding; semantic coding-remember meaning
Double Dissociation
Clive Wearing and H.M.
Functioning STM but cannot form new LTM
K.F
Poor STM but functioning LTM
Serial Position; Murdoch (1962)
read stimulus list, write down all words remembered
curve
stimuli presented at beginning
primary effect
more time to rehearse, enter LTM
stimuli presented at the end
recency effect
stimuli in STM
Types of LTM
Explicit/Declarative Memory
Episodic memory
involves mental time travel
no guarantee of accuracy
Semantic memory
not involve mental time travel
general knowledge
double dissociation
K.C. damaged hippocampus
no episodic memory
semantic memory intact
Italian woman
impaired semantic memory
episodic memory preserved
separation
activate different areas of the brain
connection
acquiring knowledge may start as episodic to semantic
semantic can be enhanced if associated with episodic
personal semantic memory
Implicit/Non-Declarative Memory
Repetition Priming
Tulving (1982); presented words then fragments to be completed, participants completed many more primed words than new words
Warrington and Weiskrantz (1968); showed fragmented pictures , participant's (Korsakoff's syndrome patients) performance improves even though the person doesn't remember training
Perfect and Askew (1994); propaganda effect
Procedural Memory
Classical Conditioning
