memory codes
for cognitive psychology
Question | Answer |
---|---|
memory code | representation used to store an item in memory |
memory code | acoustic |
acoustic | phonemic |
memory code | visual |
memory code | semantic |
semantic | meaning based |
how to control what memory code people use? | orienting task (judgment task) |
judgment task | ask a person to make a certain decision about a word |
STM capacity | 7+/-2 |
craik & lockhart (1972) | argue that decay rates very considerably depending on material being learned |
hyde & jenkins (1969) | presented 24 words in random order |
result done well | control group and rate pleasantness |
differences in recall | how much meaning of word was processed |
levels of processing theory | the greater the semantic analysis, the greater the depth of processing and more durable the memory |
the1. _____ the 2.____ analysis, the 3.____ the depth of processing and 4._____ durable the memory | 1. greater |
the1. _____ the 2.____ analysis, the 3.____ the depth of processing and 4._____ durable the memory | 2. semantic |
the1. _____ the 2.____ analysis, the 3.____ the depth of processing and 4._____ durable the memory | 3. greater |
the1. _____ the 2.____ analysis, the 3.____ the depth of processing and 4._____ durable the memory | 4. more |
different memory codes have _____ decay rates | different |
why are semantic codes better than phonemic codes? | differ in how elaborate they are |
why are phonemic codes better than structural codes? | differ in distinctiveness |
more elaborate codes = | better memory |
more distinctive codes = | better memory |
easier to retrieve | more elaborate codes |
easier to construct | elaborations at semantic levvel |
elaboration easier to construct at what level? | semantic level than structural and phonemic |
elaboration | storing associations that help you remember the target item |
distinctiveness | item that is different in appearance or meaning |
distinctiveness hypotehesis claim 1 | semantic codes are more distinctive than other codes |
primary distinctiveness | item is distinct from others in immediate context |
secondary distinctiveness | item distinct from other items in the LTM |
orthographic distinctiveness | lowercase words that have a distinctive shape |
emotional distinctiveness | items that produce an emotional response |
flashbulb memory | memory of an important event that caused an emotional reacton |
encoding specificity principle method | read sentence then target word and subject picks word that fits |
encoding specificity principle result for standard recognition task | deep processing group does better |
encoding specificity principle result for rhyming recognition task | shallow-processing group does better |
