When researchers studied Jill Price (under the pseudonym AJ), they asked her about events on specific days. People who have been diagnosed with HSAM represent a variety of ages, walks of life, and levels of intelligence. As such, this may enable people with hyperthymesia to preserve their memories. More research is necessary into both eidetic memory and hyperthymesia to understand their similarities and differences. Scientists use brain imaging tests such as MRIs and electroencephalograms to diagnose and study memory in people with HSAM. However, current research is ongoing as to whether the ability has a genetic basis. It’s not understood why some people have HSAM. [15][30] The documentary also featured 62-year-old TV producer Bob Petrella, whose memory has allowed him to catalogue the events from his "favorite days" over many years into an extensive scrapbook.

Autobiographical memory is different than other kinds of memory, such as the following: Have you ever used a rhyme or song to help you remember something?

For example, people with HSAM do not use mnemonic devices to remember long strings of information. The type of memory associated with HSAM may be called autobiographical memory or eidetic memory.

But a small number of people, including a California woman named Jill Price, can remember such events in great detail.

Hyperthymesia, also known as piking or hyperthymestic syndrome, is a condition in which an individual possesses a superior autobiographical memory, meaning he or she can recall the vast majority of personal experiences and events in his or her life. Currently the diagnosis of hyperthymesia involves complex screening and cognitive tests done in few research laboratories 21). We'll discuss what it means and how to manage it. The causes of HSAM are currently unknown, but some theories suggest that it may have biological, genetic, or psychological origins. Without pausing, she rattled off those dates correctly. This limitation means that people can only recall information about themselves and their past personal experiences. [36] Scans conducted during the studies showed that Sharrock's brain exhibited a heightened connection between the conscious and sub-conscious parts of her brain, which may aid easier memory recall – particular for events that took place earlier in life. Participants receive minimal instructions. People with hyperthymesia can recall details relating to past experiences with extreme accuracy. [3], In June 2012, the case of HK Derryberry was reported, a blind 20-year-old man who could clearly recall every day of his life since the age of about 11. As there are relatively few people with hyperthymesia, there is a lack of research examining the causes. These mostly consisted of questions pertaining to specific dates and events in history. Like autistic savants, some individuals with hyperthymesia may also have an unusual and obsessive interest in dates. Drawbacks By Deena Shefter also known as HSAM allows people to

There are some theories as to what contributes to hyperthymesia, but the exact cause remains unknown. Most people remember where they were for a marriage proposal or their first kiss. [15][better source needed] AJ's case was originally reported by researchers from the University of California, Irvine, Elizabeth Parker, Larry Cahill, and James McGaugh, and is credited as being the first case of hyperthymesia. "Her autobiographical memory, while incredible, is also selective and even ordinary in some respects," – McGaugh. This can make it difficult to attend to the present or future, as she is permanently living in the past. One of the most common is the autobiographical memory test.

On the other hand, eidetic memory is the ability to accurately recall an image after only seeing it once for a short period. Research is growing, as scientists hope to learn more about the ways circuitry in our brains processes memory. She describes how one memory triggers another, which in turn triggers another and how she is powerless to stop it: "It's like a split screen; I'll be talking to someone and seeing something else. Once cued, the memory is retrieved as episodic and follows a pattern similar to that of a spreading activation model. Researchers were able to verify many of her memories. People with HSAM process short-term memories the same way as most people do. That was a Tuesday.
