Long Term Memory Flashcards
Define Long term memory
Recall everything after 30s to years
seemingly unlimited capacity and duration
Types of long term memory
Semantic
Episodic
Procedural
priming
Semantic memory is
Facts and meaning
Knowledge about the works je capital of countries
Episodic memory is
Memory for personally experienced events - when, where, what, who
Recently evolved and late developing and most vunerable in brain injury etc
likely to be unique to humans
Procedural memory is
Memory for skills
Memory for how to do something je by practicing a skill
Difficult to explain how it is done - cant be consciously recalled
What is declarative memory
Semantic and episodic
explicit
Can declare / talk about the memory
Differences between semantic and episodic
Episodic more vunerable to forgetting, has affective links, heavily PFC, autonoetic awareness
Semantic more Noetic awareness (know info without recollection)
Cohen and squire distinction between declarative and procedural/non declarative
Episodic and semantic requires conscious awareness of reva
Procedural memory does not - implicitly retrieve the info
Explicit memory tests
Recall or recognition of words presented in a study
Implicit memory tests
Ask to do tasks that require “first thing that comes to time” or completing word stems
priming - performance thought to reflect unconscious processing of previously seen words
Define encoding
Acquiring info from the environment
thought to be influenced by the extent that we elab on info
can be purposeful (attend to stimuli) or incidental (context dependent)
Define retrieval
Ability to recall, recognise or show evidence of prior learning
can be deliberative (ie test situation) or accidental (no conscious effort)
Encoding and retrieval interaction
The way we encode the information often reflects our ability to retrieve
Is via studying
Methods of memory processes
Experimental/field
Neuroscience - brain beh mapping
Computational - models
Neuropsychology - brain damage/disease
Amnesia and distinguishing STM and LTM
Normal short term but poor long term
Therefore must be seperate systems
