Total Recall: The People Who Never Forget
An extremely rare condition may transform our understanding of memory.
If you ask Jill Price to remember any day of her life, she can come up with an answer in a heartbeat. What was she doing on 29 of August 1980? “It was a Friday, I went to Palm Springs with my friends, twins, Nina and Michelle, and their family for Labour Day weekend,” she says. “And before we went to Palm Springs, we went to get them bikini waxes. They were screaming through the whole thing.” Price was 14 years and eight months old.
What about the third time she drove a car? “The third time I drove a car was January 10, 1981. Saturday. Teen Auto. That’s where we used to get our driving lessons from.” She was 15 years and two weeks old.
The first time she heard the Rick Springfield song Jessie’s Girl? “March 7, 1982.” She was driving a car with her mother, who was yelling at her. She was 16 years and two months old.
Price was born on 30 of December 1965 in New York City. Her first clear memories start from around the age of 18 months. Back then, she lived with her parents in an apartment across the street from Roosevelt Hospital in Midtown Manhattan. She remembers the screaming ambulances and traffic, how she used to love climbing on the living room couch and staring out of the window down 9th Avenue.
When she was five years and three months old, her family – her father, a talent agent with William Morris who counted Ray Charles among his clients; her mother, a former variety show dancer, and her baby brother – moved to South Orange, New Jersey. They lived in a three-storey, red brick colonial house with a big backyard and huge trees, the kind of place people left the city for. Jill loved it.
When she was seven years old, her father was offered a job with Columbia Pictures Television in Los Angeles. He spent a year commuting back and forth from California to New Jersey, until he and her mother decided to move the family out there in the spring of 1974. By 1 of July 1974, when Jill was eight and a half, they were living in a rented house in Los Angeles. That was the day, she says, her “brain snapped”.
She had always had a talent for remembering. She had also always dreaded change. Knowing that after they left New Jersey, nothing could ever be the same, Price tried to commit to memory the world she was being ripped away from. She made lists, took pictures, kept every artefact, every passed note and ticket stub. If this was a conscious effort to train her memory, it worked, perhaps better than she ever imagined.
Price was the first person ever to be diagnosed with what is now known as highly superior autobiographical memory, or HSAM, a condition she shares with around 60 other known people. The HSAM subjects turned out to be far better than people with average memories at recalling long-past autobiographical data; in memories that could be verified, they were correct 87% of the time.
Jill can remember most of the days of her life as clearly as the rest of us remember the recent past, with a mixture of broad strokes and sharp detail. Now 51, Price remembers the day of the week for every date since 1980; she remembers what she was doing, who she was with, where she was on each of these days. She can actively recall a memory of 20 years ago as easily as a memory of two days ago, but her memories are also triggered involuntarily.
It is, she says, like living with a split screen: on the left side is the present, on the right is a constantly rolling reel of memories, each one sparked by the appearance of present-day stimuli. With so many memories always at the ready, Price says, it can be maddening: virtually anything she sees or hears can be a potential trigger.
Before Price, HSAM was a completely unknown condition. So what about the day she sent an email to a Dr. James McGaugh at University of California, Irvine? That was 8 of June 2000, a Thursday. Price was 34 years and five months old.
Dr. James McGaugh remembers that day too. At the time, he was director of UC Irvine’s Center for the Neurobiology of Learning and Memory, the research institute that he founded in 1983. In her email, Jill Price said that she had a problem with her memory. McGaugh responded almost immediately, explaining that he worked at a research institute and not a clinic, and that he’d be happy to direct her to somewhere she could find help.
Price’s reply was swift and unexpected. “Whenever I see a date flash on the television (or anywhere else for that matter), I automatically go back to that day and remember where I was, what I was doing, what day it fell on and on and on and on and on. It is non-stop, uncontrollable and totally exhausting… Most have called it a gift but I call it a burden. I run my entire life through my head every day and it drives me crazy!!!”
McGaugh was a little wary, but he was intrigued. He invited her to his office to talk.
On the morning of Saturday, 24 of June 2000, Price woke up “so, so, so excited”. She watched Apple’s Way, an obscure, short-lived 1970s series being re-run on TV, and felt, for the first time in ages, relaxed. She asked her father whether she should take all of the diaries that she had been keeping since Monday, 24 of August 1981. No, he said, don’t take them all – you’ll freak him out. She packed a bag with six years’ worth, stowed them in the boot of her car, and set off to meet McGaugh.
She drove for an hour south from her home in Encino, California, where she lived with her parents, and met McGaugh outside the Qureshey Research Building on the UC Irvine campus. It was a cloudy day, unusual for southern California. As they walked up to his second-floor office, she was still excited.
For Christmas the previous year, McGaugh had received a massive coffee-table book called 20th Century Day by Day, featuring photographs and brief accounts of the biggest news stories of the past 100 years. To test Price’s memory, he and his assistant used the book to come up with questions that someone with amazing powers of recall might plausibly be able to answer, beginning around 1974, when Price said her ability to remember really started.
Sitting across from Price, McGaugh asked, “When did the Iranian hostage crisis begin?”
After a brief pause, she answered, “4 of November 1979.”
“No, that’s not right,”he said. “It was 5 of November.”
“It was 4 of November,” she said.
He checked another source: Price was right; the book was wrong.
The rest of Price’s responses came just as quickly, confidently, and for the most part, correctly.
What day did the Los Angeles police beat taxi driver Rodney King? Sunday, 3 of March 1991.
What happened on 16 of August 1977? Elvis Presley died in his Graceland bathroom. It was a Tuesday.
When did Bing Crosby die? Friday, 14 of October 1977, on a golf course in Spain.
Price heard it on the radio in the car while her mother drove her to soccer practice.
McGaugh had been studying memory and learning for decades and he had never seen or heard of anything like this. After they had eaten lunch, Price remembers saying goodbye to McGaugh as he stood on the curb outside the restaurant, “literally scratching his head”.
Driving back, Price felt a little deflated. “I came home and I was kind of annoyed, and my dad said, ‘What did you expect, you’d get an answer?’,” she recalled. “And I’m like, ‘Yeah! And I thought I’d get a pill for it, too!’.”
Jill Price was the first person ever to be diagnosed with what is now known as highly superior autobiographical memory, or HSAM.
McGaugh is a big deal in memory research. His office at UC Irvine is situated across a courtyard from another building, McGaugh Hall, named in his honour. He has written more than 550 papers and books, many on his specialist subject of how we form long-term memories. In 2015 he received a Grawemeyer award, a significant recognition in the crowded field of psychology that comes with a $100,000 prize, for his contribution to understanding memory and emotion. The small plaque sits on a shelf on his desk. Thumbtacked to a bulletin board next to his computer monitor is a colour photograph of McGaugh – trim grey beard, square glasses, academic robes – standing behind President Barack Obama during UCI’s graduation ceremony in 2014. The funny thing about that picture, McGaugh said, is that the photographer was actually trying to get a picture of him, not the president, for an article in the Los Angeles Times about McGaugh’s 50th anniversary at the university. “This is the absolute truth, but no one will believe it!” he said, chuckling.
McGaugh, who is now 85 and closing in on retirement, first began studying memory in the 1950s. By the time Price contacted him, his research focused on showing that the more emotionally provocative an experience, the more likely the neurobiological systems involved in making memory will ensure that you remember it. When something even slightly stimulating happens, positive or negative, it causes the release of adrenal stress hormones, which in turn activate the amygdala. The amygdala then projects to other brain regions that the thing that has just happened is important and needs to be remembered. It is through this system, McGaugh explained, that the strength of our memories is controlled.
McGaugh had spent his professional career studying strongly formed memories, and Price seemed to have the strongest memories he had ever encountered. McGaugh’s earlier work had changed how we understand the mechanisms of memory, and his interest in Price was about more than just understanding her extraordinary abilities of recollection. He hoped that her unique condition could teach us something new about how we make and store memories. “The big pay-off on this,” he said, “is understanding how memory works.”
Still, he started from a position of scepticism. “In interrogating her, I started with the scientific assumption that she couldn’t do it,” he told me. And even though Price showed that she could, repeatedly, McGaugh was still unmoved. “Yeah, it got my attention, but I didn’t say, ‘Wow.’ We had to do a lot more. So we did a lot more.” (In Price’s recollection, however, her ability to remember “really freaked Dr. McGaugh out.”)
After his first meeting with Price, McGaugh assembled a team to determine the depth and breadth of her memory. Elizabeth Parker, a neuropsychologist, mapped Price’s ability to learn and remember, and Larry Cahill, a neurobiologist, helped to analyse the results. Over the next five years, Price was given a battery of standardized memory, IQ and learning tests, as well as a series of specially devised ones. For example, they asked Price, who is Jewish, to write down the date of every Easter from 1980 to 2003 – she got only one wrong and, in that case, she was off by only two days. Price was also able to say what she had done on those days.
When the researchers asked her to do the same exercise again two years later, she not only corrected the date she had got wrong, but also gave the same answers for the personal details (a sample of those details: 17 of April 1987 – “vomit up carrots”; 12 of April 1998: “house smells like ham”).
Confirming whether or not autobiographical memories are accurate is usually a tricky job but, McGaugh said, “fortunately, she kept a diary”. Price had begun recording the details of her life in earnest on 24 of August 1980, during a high-school romance she wanted to remember. She would make at least one, usually more, entry each day, comprising of short references to the most salient details of the day. Her journals were kept on calendars, on typing paper held together with binder clips, in notebooks, on index cards, even scrawled on the wallpaper in her childhood bedroom.
For Price, writing down her memories meant that they were “real”, part of a permanent historical record independent of herself. (When she dies, she told, she wants her journals buried with her, or blown up in the desert.) They also functioned as a way to pin down the swirling mess in her head, to organize her thoughts. Price says she does not re-read her journals, and given the random dates the researchers threw at her there is no reason to assume she could have prepared for their questions. The UCI researchers cross-referenced what she said she did with what was written in her diary; in some cases, they were also able to verify memories with her mother.
Over time, it became clear that Price’s autobiographical memory was potentially unprecedented. But when it came to remembering details that did not relate to her personally, Price proved no better than average. She recalled the date the Iran hostage crisis began because, as a self-described “news junkie”, she had made that detail part of her personal narrative of the day it happened. School, she says, was “torture” for her – she couldn’t remember facts and figures – but she’s unbelievably good at trivia about television of the 60s and 70s, her nostalgia years.
Other details, if they didn’t relate to her or her interests, were forgotten: once, she was asked to close her eyes and recall what her two interviewers, who she’d spent several hours with that day, were wearing – she couldn’t. When asked to look at a bank of random numbers and memorize their order in a given period of time, she laughed and said it was impossible. Price’s memory is as selective as yours or mine, storing the things that she finds important – she is just a good deal better at retaining and retrieving those memories.
There was very little scientific literature about superior forms of memory, and none about a memory like Jill Price’s. Much of what did exist was about people who had the ability to memorize pi out to 22,514 decimal places or remember the order of a randomly shuffled deck of cards. The scientific consensus about these abilities was that they were the result of practice and acquired skill – strategy, rather than innate ability. Other people who are able to name the day of the week for any given date are also able to do it for dates outside of their lifetimes, and they tend to be autistic. Price can’t and is not. There was no one – as far as the UCI team could find – who had ever exhibited anything like Price’s automatic ability to recall her personal memories.
On 13 of August 2003, three years after she first came to Irvine, McGaugh, Parker, and Cahill presented their initial findings on Jill Price’s memory to the UCI medical community in a large open forum. Price was invited to exhibit her memory, to show how she could “see” dates and memories in her head, and to explain how she conceives time: for her, each year is like a circle, with January in the 11 o’clock position, and the months progressing in an anti-clockwise motion. She was nervous about speaking in front of a large audience, especially of doctors – she has a phobia of doctors, she says – but it was the beginning of her seeing a “bigger picture” reason for her years of suffering: scientific progress.
Two years later, the UCI researchers asked Price to read a draft of the paper they had written about her before they submitted it. In it, they described Price as both the “warden and prisoner” of her memories. “I thought, God, if I didn’t know better, it sounds like this person has brain damage or something,” she said of “AJ”, the pseudonym they used for her. “I cried. I wept while I read it. Someone had finally heard me. Because I’ve spent my whole life screaming at the top of my lungs and nobody has heard anything.”
A Case of Unusual Autobiographical Remembering was published by the neuropsychology journal Neurocase in February 2006. “We made the mistake of calling it ‘hyperthymesia’” – from the Greek thymesis, remembering – “which was a terrible idea, because when you name it in that way, it sounds as if you know what it is,” McGaugh said.
In truth, all they had, in Price, was a data point of one, a lot of description, and no clear understanding of the mechanisms behind her memory. What they were about to get, however, was more people like Jill Price.
Price remembers 12 of March 2006 as a very important day. “That was the last day that my life was my own,” she told me. The following morning, the first newspaper article about the discovery of “hyperthymesia” came out in the Orange County Register. By that afternoon, McGaugh’s assistant had already been contacted by five more media outlets who wanted to interview Price. A month later, the university was getting so many calls about Price that it asked her to hire a publicist to handle all the requests. (Price, who was still known to the public only as AJ, invented a publicist and fielded all the queries herself. “I had control over what was happening. For a year, nobody knew they were talking to me,” she says, “it was really quite hysterical.”)
Almost immediately, emails also began to trickle in to McGaugh’s office from people who believed that they or someone they knew had the same condition. One email even pointed out that the scientists at UC Irvine were not the first to find someone with a memory like this – an 1871 article in the Journal of Speculative Philosophy described the curious case of Daniel McCartney, then a 54-year-old blind man living in Ohio who could remember the day of the week, the weather, what he was doing, and where he was for any date back to 1 of January 1827, when he was nine years and four months old.
Dozens of people contacted McGaugh’s lab, where his assistant handled the first round of vetting, putting potential candidates through the same public events date test that McGaugh had initially given Price. The second person verified as having the condition was Brad Williams, a radio announcer in Wisconsin whose brother contacted McGaugh in 2007 after coming across an article about the UCI research. The third was Rick Baron, whose sister had read about “AJ” in online reports.
When Bob Petrella is stuck in traffic, he scrolls through memories of that date, catalogues the best Saturdays in June he’s ever had, or tries to remember every day from 2002
The fourth was Bob Petrella, a standup comic turned writer and TV producer for reality programmers such as The Deadliest Catch. Petrella had known since adolescence that his memory was different to other people, but he never thought it was all that unusual. “I just thought it was like being a redhead or being left-handed,” he told.
Petrella sought out the UCI team after a friend suggested, on 19 of June 2007, that he should learn the science behind his memory. He was referred to Elizabeth Parker, the neuropsychologist who had co-written the original paper on hyperthymesia. They met several times. After testing him, she confirmed that, yes Petrella had it, and sent him to McGaugh for further study. He met McGaugh and Cahill for the first time over lunch on 28 of June 2008 (a “beautiful day”), where McGaugh quizzed him on dates just as he had done with Jill Price.
For the scientists, the research was exciting, but there was a concern as well, that it might all be a waste of time: given that such a tiny number of people with the condition had been identified, what could they definitively say about the condition? And what could this unique group reveal about memory? The only way to move forward was to continue testing the existing subjects and hope for more. By 2012, researchers had only identified six confirmed cases of what had been renamed highly superior autobiographical memory, or HSAM. (“Hyperthymesia”, McGaugh said, sounded “like a venereal disease”.)
In August 2010, 60 Minutes interviewed the “memory wizards” Bob Petrella, Brad Williams, Rick Baron, Louise Owen, and the actress Marilu Henner, best known for her role on the 1970s sitcom Taxi, for a segment entitled Endless Memory.
(Price was not involved; by this time, she was no longer anonymous, having published a memoir in 2008, but she had begun to sour on media appearances, which she felt reduced her condition to a “sideshow”, and she has never met any of the other people with the condition.)
It was the first time that the HSAM subjects had met anyone like themselves and, watching the show, the shock and delight in their mutual recognition is evident. When they first met on camera, there was a lot of hugging. Later, when quizzed on the date of a San Francisco earthquake, they give the answer almost in unison, some of them grinning. The programme aired on 19 of December 2010 – a Sunday night – and was seen by nearly 19 million people.
After the programme was over, McGaugh said: “I turned on my computer and I had over 600 emails.” Most were from people who believed they or someone they knew had HSAM. McGaugh spent the week between Christmas and New Year’s Day responding to the emails. Graduate and undergraduate students were pressed into service to staff a phone bank, using the public events quiz to screen callers. Most were rejected, but a small group was invited to UCI for more testing. It is a measure of just how rare HSAM is that by 2011, even after millions of people had heard about it, researchers had identified only 22 people with the condition.
In May 2012, the journal Neurobiology of Learning and Memory published a follow-up study by UCI neuroscience graduate student Aurora LePort and neurobiologist Dr. Craig Stark, then the director of the UCI Center for the Neurobiology of Learning and Memory. It was now nearly 12 years since Price first reached out to McGaugh, but researchers were only fractionally closer to finding the answer she was looking for.
In order to figure out how HSAM worked, researchers first needed to understand what it was and was not. LePort’s paper, the second to be published on the subject, established that Price and the 10 others in the study were not just high achievers on a spectrum of “good” to “bad” memory they were in a separate, outlying class by themselves. The HSAM subjects turned out to be far better than people with average memories at recalling long-past autobiographical data; in memories that could be verified, they were correct 87% of the time. And the paper was able to offer some clues as to why they could do what they do.
For example, most of the HSAM subjects described mental systems that would seemingly improve retrieval, sorting memories chronologically or categorically (as in, every 15 of April as far back as they could remember). This date-based structure seemed to help them organize their memories, as though they were tagging them for easy reference. Significantly, research shows that people with average memories are bad at temporally placing remembered events – we don’t have a sense of whether that thing happened two weeks ago or two months ago. (It is important to note here, as LePort, McGaugh, and Stark all did, that their research is limited by what they, as investigators, can verify as a real memory. Dates are the easiest and perhaps surest way to do that. “Everything we do is built around the ability to date. So are there people who have strong autobiographical memory who simply don’t bother to date them?” McGaugh said. “We’re missing them.”)
All of the HSAM subjects reported that they enjoyed replaying their memories in their minds, challenging themselves to remember days and events. When Jill Price is blow-drying her hair, she said, she flips through her memories of, say, every 4 of October she can remember. “I’ll just do like the last 40 years in my head, the last 42 years in my head,” she said. “And then I’ll turn to an imaginary person in my head and say, ‘Now you do that. Go’.”
The researchers also noted that most of the HSAM subjects exhibited obsessive behaviours. Rick Baron used to keep every banknote in alphabetical order by the name of city of the Federal Reserve Bank from which it was issued. Price has a storage space jammed with neatly organised collection of personal artefacts that she couldn’t let go of – dolls and toys, dozens of Beanie Babies, tapes of songs she recorded off the radio. Bob Petrella used to clean his groceries with an antibacterial wipe when he got home from the grocery store. “There was a nice positive correlation there, showing that the better their memory, the more OCD they were,” LePort said, adding that it makes sense: if subjects are exhibiting obsessive behaviours generally, then they might also be obsessively recalling their memories, rehearsing and therefore retrenching them, making them stronger. Every time they access that memory, it is easier because they have done it before – repetition is one of the surest ways to memorise information.
There were also neuro-physical differences between HSAM subjects and people with average memories. Examination of their brain scans showed that HSAM subjects exhibited structural differences in areas of the brain associated with autobiographical memory creation: increases in the parahippocampal gyrus, for example – an area that some studies show is engaged during the recollection of emotional memories – and increases in the uncinate fascicle, the bridge between the frontal and temporal cortices that transmits information and is involved in episodic memory retention.
But none of these findings fully explains what enables people with HSAM to remember so much. After all, correlation is not causation. Whether their mental organisational systems helped the HSAM subjects to retain memories or whether they needed to develop elaborate systems because they could retain all those memories is unclear. Plenty of people rehearse their memories and don’t have HSAM, and plenty of people with OCD don’t have incredible recall of their autobiographical memories.
Even the structural differences in the brain, though significant, do not provide a satisfying explanation for why and how HSAM works. How we use our brain can change it physically – for example, a 2011 study of London taxi drivers found that the exercise of navigating the city’s dense streets led to an increase in grey matter volume in the mid-posterior hippocampus and an accompanying decrease in volume of the anterior hippocampus. Whether the differences in the HSAM brain is the cause of their memory or, as in the London taxi drivers, the result of it, or a combination of both, remains unclear. “Pulling that apart, in science, isn’t going to be easy. Especially when your population is so rare,” said Stark.
For both Price and Petrella, there is a specific point in their lives that they feel triggered their ability to remember things with extraordinary clarity. For Petrella, it was when he was seven years old and playing a deliriously fun game in his backyard with a childhood friend. The next day, Petrella invited his friend over to play it again, but they only played for a few minutes before getting bored. Petrella realised then that nothing ever stays the same and that it was important that he remember things before they changed. For Price, it was her family’s traumatic move to the west coast. In each case, Price and Petrella say they already had strong memories before this decisive moment, but after it, their ability to remember was transformed.
When asked what he thought of these backstory narratives, McGaugh was cautious. “How much of what they say is their own attempt at explanation for what exists as opposed to what really happened?” he asked. But Craig Stark is interested in those stories. He suggested that someone who feels anxiety about losing memories, the way Price and Petrella did, might be compelled to retain them, and therefore might think about them a lot.
Despite their amazing recall, however, there is one way that HSAM subjects are just like everyone else – they are just as prone to memory “distortions”, the editing, assumptions, conflation of time, and other discrepancies that are part and parcel of making memories.
In a study published in 2013, Dr. Lawrence Patihis, a memory researcher at the University of Southern Mississippi working with scientists at UCI, asked 20 HSAM subjects and 38 people with standard memories to participate in a series of tests designed to assess their susceptibility to false memories. HSAM subjects were equally likely as the control group to claim words that had not appeared on a list had appeared, they showed a higher overall propensity to form false memories of a photographic slideshow, and they were equally likely to mistakenly report that they had seen non-existent video footage of the United 93 plane crash on 9/11.
The findings suggest that no one, not even a “memory wizard”, is immune to the reconstructive mechanisms that enable memory distortions. When people with average memory recall an experience, it is formed not only by what they think happened and how they felt at the time, but by what they know and feel now. “We’re pulling together everything in the present to come up with an approximation of the past, and that’s the same with HSAM people,” Patihis said. The findings were not popular with some of the HSAM subjects because, as Stark, a co-author on the paper, pointed out, having accurate memories is central to their identities.
But the findings square with two other important ideas. First, the initial process of encoding memories – that is, when the brain makes an experience into a memory, translating elements of that experience into a network of neurons and synaptic connections – seems no different for people with HSAM than for the rest of us.
In a study published in 2016, LePort and the other researchers tested the quality and quantity of autobiographical memories of HSAM and control groups at one week, one month, one year, and 10 years. At one week, both groups were the same in terms of the quality and quantity of information they recalled. After that first week, however, the controls’ powers of recall dropped off significantly, while HSAM people continued to be able to remember seemingly into perpetuity, with a much shallower forgetting curve. The evidence suggests that HSAM subjects form memories in much the same way as those of us with normal memories: like us, they make stronger memories of emotionally arousing experiences, and like us, they are prone to the same distortions in reconstruction.
The second idea is that however good they are at mentally representing and organising their memories, HSAM people don’t seem to be pulling up that information via a novel retrieval system. “It’s the same mechanism, it’s just better,” Stark, whose lab is now running most of the HSAM research, explained. This also implies that the thing HSAM people are doing differently to the rest of us happens somewhere in between the encoding of a memory and its retrieval – in the space where consolidation into a long-term memory takes place.
Testing that hypothesis is fairly straightforward: get HSAMs and controls into a functional MRI and ask them both to recall memories from about a week earlier, the time frame that both groups are performing at about the same level. “Are we thinking about it and reliving it in a different way?” said Stark. But that research is not happening – in part because of a lack of funding. HSAM is fascinating, but funding science for science’s sake is not popular in the US right now. Grant-giving institutions want to know what studying HSAM can do for us.
In 1953, 27-year-old Henry Molaison of Hartford, Connecticut, underwent a desperate surgery to cure his severe epilepsy. Drilling several holes in his head, surgeons performed a “bilateral medial temporal lobe resection”, essentially sucking away part of his hippocampus and much of his amygdala. The surgery worked – Molaison suffered fewer seizures – but it also left him unable to form new memories. His memories from before the surgery were intact, and he was able to learn new motor skills, but he was never able to recognise the researcher who worked with him for decades, whom he saw almost every day.
Molaison, who was known in medical journals as “HM” for the rest of his life, profoundly changed our scientific understanding of memory by showing that we don’t have a single, unified “memory system”. Instead, McGaugh explained, “We have different memory systems in the brain that handle different kinds of information for different periods of time.”
Understanding HSAM, he says, may lead to a similar revelation about the nature of memory. “That’s what is of interest,” he told. “It’s not that HSAM is interesting, it’s that memory is interesting.”
Price and Petrella said that they hoped that studying their memories could aid research that would find a cure for the thing that surveys in Britain and America show people are most terrified of: dementia. Price, with characteristic directness, said: “I expect them to find a cure for Alzheimer’s. I told Dr McGaugh, ‘This is now your turn, go. Do what you got to do… No pressure, but just find a cure for Alzheimer’s’.”
In all likelihood, studying HSAM will not lead directly to a cure for Alzheimer’s or dementia. It is still unclear whether HSAM will turn out to be a fascinating curiosity, or a key that unlocks the deepest mysteries about how memory works. At the very least, Dr. Dorthe Berntsen, founder of Aarhus University’s Center on Autobiographical Memory Research, told that it shows the extraordinary potential of autobiographical memory. “Could I, as a non-HSAM person, have memory from each day in my life stored, but I just can’t get to it? Is that a retrieval problem or is it a storage and retention problem? Potentially, it can be very important, because it asks these new questions it shows that we may have to revise how we have thought about our ability to remember the past.”
Every memory researcher describes our memories as the things that define us; they are us. There is a reason that people are more afraid of dementia than cancer. When someone you love dies, you fear the day you will forget how they laughed or the sound of their voice, because you will. It hurts to think of all the wonderful, thrilling, important, terrible, devastating things we’ve forgotten. But people with HSAM do remember. Besides the scientific questions HSAM raises, then, there is a different kind of question: would you want a memory like that, if you could have it?
“We call it forgetting but on the other hand, simple storage of information is stupid, it’s just data hoarding. What’s the point? You need to extract something useful from it, then, we call it knowledge or wisdom,” Stark told. “Memory is not about looking backward, that is not why we have it. It’s there so that your past experiences will make you more adaptive in the here and now and in the future.” But when LePort asked her HSAM subjects in the 2012 study whether they considered their hoard of memories a burden, most said they did not.
Price is cynical but not quite bitter – her life, all the details that she can remember, seems to have made her tired.
Jill Price is not representative of everyone with HSAM, but she is the first data point in this small population. And Price wrote to McGaugh on Thursday 8 of June, 2000, because she had a problem. “Everyone has those forks in the road, ‘If I had just done this and gone here, and nah nah nah,’ everyone has those,” she said. “Except everyone doesn’t remember every single one of them.” Her memory is a map of regrets, other lives she could have lived. “I do this a lot: what would be, what would have been, or what would be today,” she told.
Price is now a freelance script supervisor for film and TV. She lives in an immaculate apartment in Encino, California with her parents, with whom she has lived for much of her adult life. She has a habit of looking off to the right, to the side of the split screen where her memories are, when we talk. She is cynical but not quite bitter – her life, all the details that she can remember so clearly, seem to have made her tired, although that may be the fact that she doesn’t sleep well and hasn’t really ever. She cuts quickly to the point and doesn’t hide her emotions, but she also has an easy, though often wry, laugh.
McGaugh likes to say – and it is written on a board in the lobby of the Center for the Neurobiology of Learning and Memory – that memory is our bridge to the future. But for Price, it doesn’t feel like that. “I’m paralysed, because I’m afraid I’m going to mess up another whole decade,” she said. She has felt this way since 30 of March, 2005, the day her husband, Jim, died at the age of 42. Price bears the weight of remembering their wedding on Saturday, 1 of March 2003, in the house she had lived in for most of her life in Los Angeles, just before her parents sold it, as heavily as she remembers seeing Jim’s empty, wide-open eyes after he suffered a major stroke, had fallen into a coma and been put on life support on Friday, 25 of March 2005.
But for all the terrible things that people with HSAM can never forget, there are also wonderful memories. When Petrella turned 50, he put together the Book of Bob, a catalogue of the most memorable days he has ever had, one for each calendar day of the year. And when he recalls 15 of April 1967, he gets a kind of glow and a grin – that was the day that 16-year-old Petrella sat on the rooftop of the local newspaper, where he wrote sports pieces and obituaries, and listened to a battle of the bands contest going on in the street below. He felt like the “king of the town”, he says. “I just felt so good. I just felt so good about my life. That was my second-best April. But a time like that, just sticks in my mind.”
McGaugh told that the real question at the heart of HSAM wasn’t why his subjects remember, but why we forget. “The overall summary of all of this is that they’re bad forgetters,” he said. And forgetting is what humans do; often what we need to do. The title character in Jorge Luis Borges’s story Funes the Memorious, who acquires a perfect memory as the result of an accident, can no longer sleep because he is kept awake by the thousand mundane memories that whined like mosquitoes in his ears. The “peculiar mixture of forgetting with our remembering,” wrote William James, one of the founders of modern psychology, “is the very keel on which our mental ship is built”. “If we remembered everything,” he continued, “we should on most occasions be as ill off as if we remembered nothing.”
