The ability to recall foundational, personal life events is a function of autobiographical memory, but these memories are often known to fade and change over time. In rare cases, however, some individuals can recall specific names, dates, and events with unusual accuracy and emotional detail. This rare ability, known as hyperthymesia or autobiographical hypermnesia, enables individuals to recall a large number of life events in exceptional detail. In hyperthymesia, memories are precisely indexed. TL describes her autobiographical memories as being stored in a ‘white room,’ where binders are organized by theme and date.
