Long Term Memory

A lot of people can't remember what they had for breakfast this morning, but have no problem recalling what they ate for breakfast years ago someplace. The ability to retrieve information that concerns something that took place long ago is called “Long-term memory” or LTM. It is the brain's warehouse of material, something that remains permanently stored, but something you always have access to.
In general, people have an easier time remembering material stored in LTM than material stored in STM. Much of the memory stored in LTM is used everyday, like procedural memory, the ability to remember how to do certain things, like use a can opener. Other types of LTM include episodic memory, remembering something specific that took place at a certain point in time, like what you ate in a particularly classy restaurant and semantic memory, the ability to recognize specific meanings or functions of things or objects, like what a car is or what a specific word refers to.
Long Term Memory is usually more robust than STM and often intact even when people have memory disorders affecting STM.
