The person consciously processes information. Working memory has two important characteristics: its limited capacity and the loss of information over time. Working memory begins at age six but becomes more efficient as the years go by. It is important to regularly activate the desired information so as not to lose it. The next term is long-term memory and it is permanent; it can be knowledge or events and its capacity is unlimited. Although you want to memorize as much as possible, not everything you learn will be stored in your long-term memory. There may be some problems with long-term memory, such as initially encoding information, storing it (placing it in the long-term area), finding the right information, and retrieving the information. Long-term memory increases with age. Then there is reconstructive memory: when we remember situations, we remember pieces of the event, but then we make up the rest based on what we can deduce from our memory. It is very difficult to remember a memory before the age of three or four, which is called infantile amnesia and there are autobiographical memories linked to someone of great importance and which are vivid.
