L1 - STM Flashcards
Define memory
The process of acquisition, storage (encoding) and retrieval of information
What type of store is STM?
a unitary store
is the STM separate from the LTM?
yes
How do you prevent decay in the STM?
by maintaining rehearsal
what are the 3 features of the STM?
capacity
duration
encoding type
What does research suggest about capacity?
7+ / 2-
can store between 5-9 pieces of info
What does research suggest about duration?
18 - 30 seconds
What does research suggest about encoding?
acoustic
Explain the study of capacity
Participants presented with string of digits
Asked to recall them
Longest length recalled is their digit span
5-9
However, Miller found ppl can remember more if the used chunking
Explain the study of duration
The Peterson- brown technique
Given trigram
Asked to recall after various durations
During the retention interval participants must found backwards to prevent rehearsal
Longer retention interval, less likely to remember
Explain the study of encoding
Presented with 2 lists of letters or words
One list similar sounding (cap, can, cat)
Other different sounding (man, cat, beg)
For immediate recall, similar harder
