Coding Flashcards
Short Term Memory
we sometimes try to keep information active by repeating it to ourselves
Short Term Memory coding
acoustic
Long Term Memory
it’s more useful to code words in terms of their meaning, rather than what they sound or look like
Long Term Memory coding
semantic but can also be visual or acoustic
Visual

Acoustic

Semantic

Baddeley study
investigating coding in short term memory and long term memory
Method
Participants were given four sets of words that were either acoustically similar, acoustically dissimilar, semantically similar or semantically dissimilar
Method - independent groups
The experiment used an independent groups design - participants were asked to recall the words either immediately or following a 20 minute task
Results: Short Term Memory
Participants had problems recalling acoustically similar words when recalling the word list immediately from short term memory.
Results: Long Term Memory
If recalling after an interval from Long Term Memory, they had problems with semantically similar words
Conclusions
The patterns of conclusion between similar words suggesting that Long Term Memory is more likely to rely on semantic coding and Short Term Memory on acoustic coding
Evaluation: Ecological Validity
The study lacked ecological validity
Evaluation: other types of LTM
Episodic Memory
Procedural Memory
