So Baddeley found that participants using STM to recall struggled the most with recalling acoustically similar words, whilst those who used LTM struggled the most with recalling semantically similar words. From this, he concluded that STM relies on acoustic coding and LTM relies on semantic coding.
Can anyone please explain how he reached this conclusion?

This also confused me when I first studied it and It took a while for me to understand. Basically he came to this conclusion as after finding out semantically similar words were not remembered as well as any of the other conditions including acoustically similar, it showed that LTM encodes semantically because the LTM paid attention to the semantic meaning and when it came down to recall, the brain confused all the meanings together.
an example of this is for example if you remember a conversation you had with someone, you are likely to remember how it made you feel, eg sad, but not the exact words or sentences that were exchanged. This is because the information was encoded semantically. if it encoded acoustically, you would be able to remember the exact words.
This shows its not acoustically as the LTM pays no attention to the sounds. you may also apply this to STM, as less words were recalled when acoustically similar.
badeley also found the even though semantically similar words had a lower remembrance rate, as he progressed through the 4 stages and 5th surprise one, he found that semantically similar words stuck in participants head for longer, and less forgetting took place even though the overall score was lower

It’s due to the research around that time. It appeared to convey that short term memory worked acoustically. The question was probably is long term memory the same in this way or is it different and does it involve semantic connections between the words to allow the memory to be stored?
