What is Memory?
‘I think of memory as a general capacity to acquire, retain and use information.’(Tulving, 1999)
What are the types of memory?
Sensory
•e.g. visual memory after images
Short-term memory (STM)
•Remembering a telephone number for the time it takes to dial it
Long-term memory (LTM)
•Remembering your own telephone number
How memory can be forgotten
If information is not attended to, perceived (sensory), or rehearsed/processed (short-term & long-term) for some time it may be forgotten
- This would be more quickly forgotten in sensory register and short-term memory
What is short term memory?
(= Working memory)
What is long-term memory?
Depends on the formation of associations between nodes when they have been activated in working memory.
- Can be split into declarative memory and non-declarative memory
What is the difference between declarative memory and non-declarative memory?
Declarative memory allows us to consciously recall and recollect events and facts. Nondeclarative memory, in contrast, is accessed without consciousness or implicitly through performance rather than recollection.
How are memories created, kept, and used?
Encoding
•How does information get ‘in’ to long-term memory?
Rehearsal and Level of Processing
Level of processing thought to be key (e.g. thinking of meaning behind facts / information, more important than repeating facts)
How are memories affected by emotions?
Flashbulb memories
Why are FBMs relevant in medical contexts?
* Practitioners might be put in surprising / emotional situations
“Flashbulb” memory at higher arousal
•we may direct our narrowed attention to emotions rather than facts
Patients respond to doctors’ anxiety (Shapiro et al., 1992)
Patients may “rehearse” emotions more than facts
