Midterm 2 Flashcards
(54 cards)
what is sensory memory
the part of meteor that holds preliminarily analyzed sensory information for a fraction of a second to a few seconds. hearing, seeing, subliminal processing. lost if does not enter short-term memory
what is short term memory
-where info is temporarily stored while people are actively processing it.
what is discursive processing:
verbal processing, word logos
what is imagery processing
visualize an experience, word logos with a picture
what are the characteristics of short term memory
- limited in duration: lost if not enter long term memory
- limited in capacity
what are people better at recognizing, discursive or imagery processings
people are better recognizing and recalling pictures than words.
what is dual coding theory
a theory that memory is improved when items can be represented by both discursive and imagery memory codes.
what is the capacity of STM
- people can only hold about 7 items in their STM.
- consumers that receive an overload of info can become frustrated. a rule of thumb in tv ads is to add no more than 4 bits of info.
- involvemnet and motivation influence capacity of STM
what is long term memory
memory that has no capacity limits and hold information from minutes to an entire lifetime
How does LTM connect with STM
- encoding: writing info from STM to LTM
- retrieval: obtaining info from LTM to STM
what are the characteristics of LTM
- no limit to capacity
- no limit in duration
what is autobiographical (episodic) memory
- knowledge we have about ourselves and our past
- personal and idiosyncratic
what is semantic memory
- memory of general knowledge
- not associated with specific episodes
how can you enhance memory
- chunking: grouping info into chunks
- rehearsal: actively repeating verbal info
- recirculation: being exposed to the same info repeatedly
- elaboration: processing information at deeper levels
how is LTM organized
- semantic/associative networks
- retrieval failures
What is a semantic (associative) network
example of someone going on a ski trip : what he remember the most, that appeal to him and what he doesn’t at all lie the busses to the mountain
what are retrieval failures
basically forgetting; failure to retrieve information from LTM
what is decay
forgetting occurs because trace strengths fades spontaneously over time
what is interference
- semantic networks are so closely aligned that consumers fail to remember which features go with which brand.
- caused by similar info encountered before or after learning
how do you minimize interference
- make info salient from the environment
2. make info as dissimilar as possible from earlier and later material
what are the types of retrieval
- recognition
- recall
what is recognition
when presented with a stimulus, people identify that stimulus as they have seen before
what is recall
-retrieve info from LTM without any aid which is more extensive than recognition
how does consumers mood affect retrieval
if in a positive mood it tends to enhance the recall of stimuli and positive info, compared to negative mood which recalls negative info
