Memory Flashcards
Encoding
Process of putting new info into memory
Can be automatic or effortful
Semantic encoding is stronger than both acoustic and visual encoding
Sensory and Short Term memory
Transient, based on NT activity
<1 sec
Working Memory
Requires short term memory, attention, and executive function to manipulate information
<1 min
Long term memory
requires elaborate rehearsal and is the result of increased neuronal activity
Explicit
Implicit
Life-time
Explicit memory
part of long term
conscious
–> declarative (facts, events)
Implicit memory
part of long term
unconscious
–> procedural (skills, tasks)
Declarative memory (2)
part of explicit under longterm memory
Episodic (events, experiences)
Semantic (facts, concepts)
Semantic Networks
Stores facts
concepts are linked together based on similar meaning
certain triggers will activate associated memories
Retrieval
recognition of info is stronger than recall
retrieval is often based on priming interconnected nodes of the semantic network
Memory Diseases (3)
- Alzheimers
- Korsakoff’s Syndrome
- Agnosia
Alzheimers
Degenerative brain disorder linked to a loss of acetylcholine in neurons that link to the hippocampus
Causes dementia and memory loss
Korsakoff’s Syndrome
Memory loss is caused by thiamine deficiency in the brain
Causes retrograde amnesia and anterograde amnesia
Another symptom is confabulation, the fabrication of vivid but fake memories
Agnosia
loss of ability to recognize objects, people, or sounds
usually caused by physical damage to the brain
Interference (2)
- Retroactive
2. Proactive
Retroactive interference
New memories make you forget old memories
