Genetic studies are conducted in collaboration with Dr. We have also identified several children with this ability, and are now conducting genetic studies in twins to understand the potential genetic basis of this ability.
Furthermore, MRI studies of their brain show preliminary evidence of specific regions and networks that may be different from control participants, although this is work that is still quite preliminary. So far, the studied conducted at UC Irvine suggest that individuals with HSAM have superior abilities in autobiographical memories but are no different from age- and sex-matched control participants on standard laboratory memory tests.
If you suspect you might have this ability, click here to take the screening. There is also a strong cultural bias in the questions typically asked.Ĭurrently, we are developing new tools to probe this phenomenon that do not rely on individual expertise or explicit knowledge of public events. However, it is now clear that these tests rely heavily on expertise as well as the age of the participant. Memory for public events has typically been used as a screening criterion which is then followed by more rigorous memory testing. Where we stand: So far, a number of other individuals have been identified with similar abilities and a number of other research groups have begun to explore this phenomenon. Read all of the scientific reports here. The phenomenon and the work have been highlighted in numerous media venues. Since then, more individuals with this extraordinary ability have been identified (over 50 now), and CNLM researchers have been working to understand this mysterious ability. The condition was renamed to HSAM from its original label, hyperthymesia, which was used in the original report. When provided with a date, Jill could specify on which day of the week it fell and what she did that day. Initial Discovery: In 2006, Professor James McGaugh and colleagues reported the first known case of HSAM in a research participant known as “AJ”, later identified as Jill Price. Individuals with HSAM have a superior ability to recall specific details of autobiographical events, tend to spend a large amount of time thinking about their past and have a detailed understanding of the calendar and its patterns. Highly Superior Autobiographical Memory (HSAM) is a memory phenomenon first described by researchers at the Center for the Neurobiology of Learning and Memory at UC Irvine.
