Short-Term Memory
Short-term memory takes information from sensory memory and sometimes connects that memory to something already in long-term memory.
Recall is somewhat better for random numbers than for random letters (Jacobs, 1887), and also often slightly better for information we hear (acoustic encoding) rather than see (visual encoding) (Anderson, 1969).
Long-term Memory
long-term memory (LTM): the continuous storage of information
Unlike short-term memory, the storage capacity of LTM has no limits.
Explicit memories are those we consciously try to remember and recall.
Explicit (declarative) memory has two parts: semantic memory and episodic memory.
