The thesis of two separate memory systems: the **long-term memory** and the **short-term memory** is today considered to be true. Some of the evidence for this thesis are: | The thesis of two separate memory systems: the **long-term memory** and the **short-term memory** is today considered to be true.

Another term should be clarified here: the [[memory_models:human_working_memory|working memory]], which is often mistaken for the short-term memory. The main difference between these two is that working memory usually includes the structure and processes performed by a system in control of the short-term memory. | Another term should be clarified here: the [[memory_models:human_working_memory|working memory]], which is often mistaken for the short-term memory.
