In psychology, memory is an organism’s capability to store, preserve, and then recover the same information. Generally, the classifications of memory used the sensory, short-term and long-term memories. The first two classes are only available for a short period of time compared to long-term memory which could last for a life-time.
Short-term memory can be defined as the ability to remember an insubstantial amount of information for a short period of time. An example of this is when someone is given a phone number and is forced to memorize it because there is no way to write it down.
