* Acoustic: This involves the sound of the information, which can be important for remembering things like names or phone numbers.
* Visual: This involves the visual appearance of the information, which is crucial for remembering faces, objects, and locations.
* Semantic: This involves the meaning of the information, which helps us to understand and connect different pieces of information.
So, short-term memory is not purely phonetic, but it is a combination of different coding systems, including acoustic, visual, and semantic.
Additionally, short-term memory has a limited capacity and duration. This means that information is not stored permanently in short-term memory but must be actively rehearsed to be transferred to long-term memory.
In contrast, long-term memories are primarily stored semantically, based on their meaning and connections to other information.
