The Californian researchers came out some of the most bizarre facts about hyperthymesia that is to say, the individuals possessing exceptional memory can only remember those events that bear personal importance for them. The hyperthymestic individuals are believed to have uncontrollable associations while they recall a date or event, and they visualize the dramatic reflection of that event within their minds. It is curious that these superhumans recall past memories without putting too much stress on their minds. It’s like they are not doing anything extraordinary.
