Memory

Memory is an active process in which information is received, organized, altered, stored, and recovered.

Memories are often lost, altered, revised, or distorted. Different strategies are required to make the best use of short-term memory and long-term memory.

Remembering is not an all-or-nothing process. Information that appears to be lost may still reside in memory.
An inability to retrieve information isn't the only cause of forgetting. Often, memory failures occur because information wasn't stored in the first place.

Although it's true that some people have naturally superior memories, everyone can learn to improve his or her memory. Memory systems (mnemonics) may help in the short term. However, coventional learning tends to create the most lasting memories.
