the way information is changed so that it can be stored in the memory
How is the memory coded in the STM?
Acoustically
How is the memory coded in the LTM?
Semantically
Who studied coding of memory?
Baddeley
How did Baddeley investigate coding?
word lists
some were semantically similar and some were acoustically similar.
Asked to recall in order straight away then 20 minutes later
What did Baddeley find?
Immediate recall was worse with acoustically similar words.
After 20 minutes recall was worse with semantically similar words
What did Baddeleys findings tell us about coding in the STM and LTM?
STM is acoustic
LTM is semantic
Strength
Identified two memory stores, later research showed there are exceptions but STM is mostly acoustic and LTM is mostly semantic, led to development of multistore model
Limitaton
artificial stimuli, no personal meaning to tells us little for everydaymemory tasks, when processing meaningful info people use semantic coding in STM, limited application
