Lecture 8 - Memory Cont'd Flashcards
cognitive vs motor memory
the memory systems for cognition (or thought) are similar but they’re are not the same as those for action (or movement)
motor memory vs muscle memory
Motor memory lies within the nervous system (i.e. neural synapse) there is a neural substrate for memory/learning
Muscle memory lies within the muscle, skeletal muscle itself has no memory for movement (it obeys neural instruction from nervous system)
Consolidation
*applies for cognitive memory but probably not for motor memory
- > refers to the process by which a temporary, labile memory is transformed into a more stable, long-lasting form
retrieval
- > active and dynamic process
- > triggered by partial recall (re-membering)
- > interpretive process
notable features of memory
- > its basic function is thought and action
- > it is fallible (imperfect)
- > can produce false memories
different memory systems
- > short term sensory stores
- > short term
- > long term
short term sensory stores
stores the sensory information for a brief period (100-2000ms)
- > old info is continuously being replaced with new information
selective attention allows for what?
the process of selective attention allows the relevant information from STSS to be accessed for further processing by STM
short term memory
is a temporary info store that is sometimes referred to as working memory
- > thus info from the other memory systems is transfered to STM for processing
how long does STM last
1-60 secs
- > if info is to be retained then it must be rehearsed
- > limited to 7 +/- 2 bits but with practice can be increased to around 80 (chunking)
long term memory
permanent, vast capacity for storage
learning involves
the active transfer of info from STM to LTM
- > information is retrieved from LTM as processed in STM as required
