Researchers understand that memory can be subdivided into several components. Short-term memory involves remembering small amounts of information for a period of a few seconds. It is believed that the capacity for short-term memory is to remember 7 items + 2 and the maintenance of this process is dependent on prefrontal cortex. After this time period, memories are consolidated in the hippocampus and there they can be retrieved over long periods of time.

The Human Difference: 

Short and long-term memory processes are undoubtedly similar in humans and other hominids

Universality in Human Populations: 

Universal, affected by aging
