Upper memory

The Hypertimesia or Autobiographical Superior Memory, has become a known phenomenon thanks to the television series "Unbearable" (Unforgettable) and also the publicity surrounding Hollywood actress Marilu Henner, who is one of the 12 known people in the world who are able to remember their lives in detail with all the events they have personally experienced.

People with hyperthymia they are able to remember the events of any given calendar date, generally since puberty, with impressive and precise detail. You can compare similar dates, or days when the weather was rainy or that were in a certain place. This autobiographical superior memory makes it possible for people to use their minds as true databases, and they can remember unusual details, such as the clothes they were wearing, those they may have known that day, and what they ate for lunch, even decades After the original event. A study on hypertimesia also indicates that people with this talent they have difficulties in their relationships, which can be a side effect of always being concrete about details, in conversations and things that happened. For this reason it may be difficult to argue with someone with this curious ability, it must also be extremely difficult to lie to someone who can analyze everything he has done every day and discover any incorrectness in his story.

Characteristics of hyperthymia

Some of the characteristics that define hyperthymia include the ability to "see" the representations of the days in the head without any conscious effort and remember events that have a personal meaning. It is distinguished from other forms of exceptional memory, since it does not imply any type of practice or mnemonic tricks To store information, it is not the same as individuals who can consciously memorize long lists of numbers or chains of random facts. Studies have shown that hypertimésticos are not like the "savant" or "autistic", although they do show an interest and great memory for dates, which they use often and effortlessly to categorize when a particular event happened in their lives

The condition was defined in 2006, and all individuals who are hypertimésicos are left handed, which could be a coincidence or an indicator of this condition. It is also said that some detrimental effects on this ability to remember may be detrimental to their daily activity, and although people may be able to associate events with dates, they have no photographic memory and they may still have difficulty memorizing common information.

Theories about superior autobiographical memory

Some theories about how the hyperthystic subject encodes his memories lead to believe semantic signals those used to retrieve information, but it should be possible to study a larger group of people with hyperthymia to create a better scientific model of how memories are stored and subsequently reproduced.

There are many types of higher memory detected in different people, but usually those with the best memory talents are usually born with them, although there are individuals who developed a great potential for memorization through practice and time, which allowed to learn numerous languages ​​and skills.
