Lecture 07 Long-term Memory Flashcards
Serial Position Curve
Distinction between short-term and long-term memories
Primacy Effect
Rehearse -> long-term memory
Recency Effect
30 secs delayed eliminated recency effect
Coding
Form in which stimuli are represented
- Visual and auditory
- Semantic
Semantic Coding in Short-Term Memory
Proactive interference doesn’t affect when semantic changes
Semantic coding in long-term memory
Recognition memory
LTM in the Brain
- H.M.: Hippocampus
- Clive Wearing: Medial temporal lobe
- Retains STM
- Can’t form LTM
STM in the Brain
- K.F.: Parietal lobe
- impaired STM
- form LTM
Types of Long-Term Memory
- Explicit
- Episodic
- Semantic - Implicit
- Procedural
- Priming
- Conditioning
Episodic Memory
Events that happened in the past
Semantic memory
General knowledge
K.C.: Damaged Hippocampus
- No episodic memory
- Semantic memory intact
Italian Woman
- Episodic memory intact
- Impaired semantic memory
Episodic and Semantic Memory Interaction
- Episodic can be lost
- Leaving only semantic
Semantic can be enhanced by…
Associated with episodic
- Autobiographical memory
- Personal semantic memory
Time Affects Memories
Forgetting increases with longer intervals after encoding
Familiarity
Semantic memory by recognition
Recollection
Episodic memory by recall
Constructive Episodic Simulation Hypothesis
- Episodic memories are extracted and recombined to create simulations of future events
- Anticipate future needs and guide
future behaviors - Mind wandering
- K.C.: loss episodic memory + can’t imagine future event
Implicit Memory
Learning from experience is not accompanied by conscious remembering
Procedural Memory
Skill memory: memory for actions
- No space-time need
- H.M.: cannot form new LTMs, can still learn new skills
Priming
Priming stimulus changes person’s response to a test stimulus
- Propaganda effect
- Unaware of previously seeing or hearing statement
- Advertisements
Propaganda effect
More likely to rate statements read or heard before as being true
Classical Conditioning
The person has forgotten about original pairing of the stimulus and the response
