lecture 6 memory Flashcards
3 systems of memory
- sensory
- short-term
- long-term
memory systems in long term?
- declarative; episodic and semantic
- non-declarative; procedural, conditioned responses, priming
process from short to long term memory
rehearsal in STM leads to encoding in LTM. when needed retrieval from LTM to STM.
Short term memory?
- phonological loop
- visuo-spatial sketchpad
- central executive
- episodic buffer
phonological loop
loop of ~2 seconds that stores verbal info via rehearsal.
loop in seconds instead of items explains why longer words are harder to memorize than shorter words.
visuo-spatial sketchpad
for visual and spatial material
central executive
attentional system for coordination
episodic buffer
for temporal storage of information for integration STM/LTM
Long term memory 3 codes
- verbal
- visual
- motor
(almost) unlimited storage in these.
implicit memory as defined in the book and the problem with it?
they explain explicit as declarative, but implicit definition is not the same as non-declarative.
with their definition of implicit a lot of declarative (explicit) memories become part of the implicit, which is confusing.
“influence of memory on behavior, but without remembering the relevant experience, or without awareness of influence of that experience on current behavior”
explicit memory
conscious recall
- semantic knowledge: facts and general knowledge
- episodic memory: personal experiences
implicit memory
no conscious recall
- procedural memory: motor and cognitive skills
- priming: enables enhanced identification of stimuli
- conditioned responses: bell-food (pavlov)
why does advertising not result in implicit memories?
procedural memory is not relevant, enhanced identification is not needed because of the brand name written on the product. an ad could lead to a conditioned response, but the influence of that is small to the heuristics we actually use.
are measures of implicit memory a valid way of assesing impact of advertising on memory?
the standard measure of ad effectiveness is to measure explicit recal, but this is an invalid measure of purchase intentions.
why is measuring ad recall an invalid way of measuring impact on memory?
- effects on implicit memory are not detectable with measures of explicit memory
- recollection of arguments made in an advertisement may be unrelated to consumers’ attitude
