w8 Flashcards
what is the law of repetition
More (maintenance) rehearsal- better retention
what is encoding/acquisition
- Transformation from perceptual representations into
cognitive/attentional focus - Attention to select between what is relevant and what is left out
what is storage/maintenance
how information is kept in the focus of attention (STM) or in long term storage (LTM)
what is retrieval
Bringing back into focus of attention
3 elements of the MSM
sensory memory, STM, LTM
what does the sensory store do when there are intermittent blanks
Fills in the blanks
what is the function of the sensory store
To keep sensory information in mind so we can attend to it
iconic memory –
vision
echoic memory-
hearing
haptic memory-
touch
olfactory memory-
smell
gustatory memory-
taste
does info in the sensory store need attention
no
info in the sensory memory is pre-categorical, meaning…
it is not yet interpreted
what did Sperling conclude about the capacity of iconic memory
Large amount held in iconic memory (perhaps anything entering the visual system
what did Sperling conclude about the duration of iconic memory
After about 250-500 ms, performance approached full-report condition
function of STM
Conscious processing of information
why is attention so important for STM
Limits what info comes under the spotlight of short-term memory at any given time
what is the capacity of STM
Magical number 7±2
how can capacity of STM be increased
chunking
define chunking
repackaging of material into conceptual unit
what does chunking require
requires recoding (strategy from LTM)
issue with magical number 7±2
many studies show drop off after 4 items, original experiment allowed for chunking
what is Stenberg’s slope
People scan STM in a serial exhaustive fashion (don’t stop even if a match is found)- the scan rate is about 38 ms per item
