Abstract

Over the past decade, a debate has emerged between those who believe that memory-modulating technologies are inherently dangerous and need to be regulated and those who believe these technologies present minimal risk and thus view concerns about their use as far-fetched and alarmist. This article tackles three questions central to this debate: (1) Do these technologies jeopardize personhood? (2) Are the risks of these technologies acceptable? (3) Do these technologies require special regulation or oversight? Although concerns about the unethical use of memory-modulating technologies are legitimate, these concerns should not override the responsible use of memory-modulating technologies in clinical contexts. Accordingly, we call for careful comparative analysis of their use on a case-by-case basis.

Additional Questions about the Applicability of “False Memory” Research

Kathryn Becker-Blease and Jennifer J. Freyd
Applied Cognitive Psychology, (2016)
DOI: 10.1002/acp.3266

Summary

Brewin and Andrews present a strong case that the results of studies on adults' false memories for childhood events yield small and variable effects of questionable practical significance. We discuss some fundamental limitations of the literature available for this review, highlighting key issues in the operationalization of the term 'false memory', publication bias, and additional variables that have been insufficiently researched. We discuss the implications of these findings in the real world. Ultimately, we conclude that more work is needed in all of these domains, and appreciate the efforts of these authors to further a careful and evidence-based discussion of the issues.

The empty brain

Here are two excerpts:

Forgive me for this introduction to computing, but I need to be clear: computers really do operate on symbolic representations of the world. They really store and retrieve. They really process. They really have physical memories. They really are guided in everything they do, without exception, by algorithms.

Humans, on the other hand, do not – never did, never will. Given this reality, why do so many scientists talk about our mental life as if we were computers?

(cut)

Misleading headlines notwithstanding, no one really has the slightest idea how the brain changes after we have learned to sing a song or recite a poem. But neither the song nor the poem has been ‘stored’ in it. The brain has simply changed in an orderly way that now allows us to sing the song or recite the poem under certain conditions. When called on to perform, neither the song nor the poem is in any sense ‘retrieved’ from anywhere in the brain, any more than my finger movements are ‘retrieved’ when I tap my finger on my desk. We simply sing or recite – no retrieval necessary.

Editor's note: This article may help clinician's reflect on the way we discuss memories and change with our patients.  Our understanding of how the brain works is quite limited.  And, the brain is not like a computer.

Memories of unethical actions become obfuscated over time

Maryam Kouchakia and Francesca Gino
PNAS 2016 ; published ahead of print May 16, 2016
doi:10.1073/pnas.1523586113

Abstract

Despite our optimistic belief that we would behave honestly when facing the temptation to act unethically, we often cross ethical boundaries. This paper explores one possibility of why people engage in unethical behavior over time by suggesting that their memory for their past unethical actions is impaired. We propose that, after engaging in unethical behavior, individuals’ memories of their actions become more obfuscated over time because of the psychological distress and discomfort such misdeeds cause. In nine studies (n = 2,109), we show that engaging in unethical behavior produces changes in memory so that memories of unethical actions gradually become less clear and vivid than memories of ethical actions or other types of actions that are either positive or negative in valence. We term this memory obfuscation of one’s unethical acts over time “unethical amnesia.” Because of unethical amnesia, people are more likely to act dishonestly repeatedly over time.

Machines That Will Think and Feel

Here is an excerpt:

AI prophets envision humanlike intelligence within a few decades: not expertise at a single, specified task only but the flexible, wide-ranging intelligence that Alan Turing foresaw in a 1950 paper proposing the test for machine intelligence that still bears his name. Once we have figured out how to build artificial minds with the average human IQ of 100, before long we will build machines with IQs of 500 and 5,000. The potential good and bad consequences are staggering. Humanity’s future is at stake.

Suppose you had a fleet of AI software apps with IQs of 150 (and eventually 500 or 5,000) to help you manage life. You download them like other apps, and they spread out into your phones and computers—and walls, clothes, office, car, luggage—traveling within the dense computer network of the near future that is laid in by the yard, like thin cloth, everywhere.

AI apps will read your email and write responses, awaiting your nod to send them. They will escort your tax return to the IRS, monitor what is done and report back. They will murmur (from your collar, maybe) that the sidewalk is icier than it looks, a friend is approaching across the street, your gait is slightly odd—have you hurt your back?

Implanting and Erasing Memories: Life-Changing, or Taking Science Too Far?

By Jordan Gaines Lewis
Gaines, on the Brain
Originally published November 9, 2015

Here is an excerpt:

But what if doctors and researchers could attack PTSD at the source: actually implanting or erasing specific memories in a person's brain?

It may sound like science fiction — not unlike Lord Voldemort luring Harry Potter to the Ministry of Magic by creating false images in Harry's mind, or the entire premise of the movie Inception — but science is actually getting close. In mice, neuroscientists have found ways to not only identify the location of certain memories, but to actually manipulate those memories.

But can we do this in humans — in patients with PTSD? And perhaps the bigger question: should we?

An Important Step in Artificial Intelligence

By Sonia Fernandez
UC Santa Barbara Press Release
Monday, May 11, 2015

In what marks a significant step forward for artificial intelligence, researchers at UC Santa Barbara have demonstrated the functionality of a simple artificial neural circuit. For the first time, a circuit of about 100 artificial synapses was proved to perform a simple version of a typical human task: image classification.

“It’s a small, but important step,” said Dmitri Strukov, a professor of electrical and computer engineering. With time and further progress, the circuitry may eventually be expanded and scaled to approach something like the human brain’s, which has 1015 (one quadrillion) synaptic connections.

For all its errors and potential for faultiness, the human brain remains a model of computational power and efficiency for engineers like Strukov and his colleagues, Mirko Prezioso, Farnood Merrikh-Bayat, Brian Hoskins and Gina Adam. That’s because the brain can accomplish certain functions in a fraction of a second what computers would require far more time and energy to perform.

The disremembered

Dementia undermines all of our philosophical assumptions about the coherence of the self. But that might be a good thing

By Charles Leadbeater

Here are two excerpts:

The memory-based account of identity is powerful, deeply rooted and dangerously partial. It will direct us to potential memory cures – a mixture of implants and drugs – that will almost certainly disappoint as much as they excite. Memory is not created in a little box in the brain, but by diffuse and dispersed circuits of neurons firing in concert. Someone with dementia would need more than an implant: they would need their brain refreshed and rewired. And still the nagging question would remain: are they the same person?

(cut)

The notion of an embedded identity takes us into much more fertile territory when it comes to considering meaningful care for dementia sufferers. It implies that the main challenge is to work imaginatively and empathetically to find common ground, creating conversational topics and cues that help make connections with people, despite their failing memory. As the British psychologist Oliver James explains in Contented Dementia (2008), this requires more skill and persistence than most conversations demand, precisely because its pre-suppositions cannot be taken for granted. My 85-year-old mother-in-law, for example, cannot always remember that she has a preserving pan, but that does not stop her enjoying making (and, even more, talking about making) marmalade.

People can be convinced they committed a crime that never happened

Association for Psychological Science
Press Release on January 15, 2015

Evidence from some wrongful-conviction cases suggests that suspects can be questioned in ways that lead them to falsely believe in and confess to committing crimes they didn't actually commit. New research provides lab-based evidence for this phenomenon, showing that innocent adult participants can be convinced, over the course of a few hours, that they had perpetrated crimes as serious as assault with a weapon in their teenage years.

The research, published in Psychological Science, a journal of the Association for Psychological Science, indicates that the participants came to internalize the stories they were told, providing rich and detailed descriptions of events that never actually took place.

"Our findings show that false memories of committing crime with police contact can be surprisingly easy to generate, and can have all the same kinds of complex details as real memories," says psychological scientist and lead researcher Julia Shaw of the University of Bedfordshire in the UK.

Psychologists and psychiatrists serving as expert witnesses in court: what do they know about eyewitness memory?

Annika Melindera & Svein Magnussena
Psychology, Crime & Law
Volume 21, Issue 1, 2015, pp 53-61

Abstract

Expert witnesses have various tasks that frequently include issues of memory. We tested if expert witnesses outperform other practitioners on memory issues of high relevance to clinical practice. We surveyed psychiatrists and psychologists who reported serving as expert witnesses in court (n = 117) about their knowledge and beliefs about human memory. The results were compared to a sample of psychiatrists and psychologists who had never served as expert witnesses (n = 819). Contrary to our expectations, the professionals serving as expert witnesses did not outperform the practitioners who never served. A substantial minority of the respondents harbored scientifically unproven ideas of human memory on issues such as the memory of small children, repression of adult traumatic memories, and recovered traumatic childhood memories. We conclude that the expert witnesses are at risk of offering bad recommendations to the court in trials where reliability of eyewitness memory is at stake.

The self is moral

We tend to think that our memories determine our identity, but it’s moral character that really makes us who we are

By Nina Strohminger

Aeon Magazine

Originally published November 17, 2014

Here is an excerpt:

Recent studies by the philosopher Shaun Nichols at the University of Arizona and myself support the view that the identity-conferring part of a person is his moral capacities. One of our experiments pays homage to Locke’s thought experiment by asking subjects which of a slew of traits a person would most likely take with him if his soul moved to a new body. Moral traits were considered more likely to survive a body swap than any other type of trait, mental or physical. Interestingly, certain types of memories – those involving people – were deemed fairly likely to survive the trip. But generic episodic memories, such as one’s commute to work, were not. People are not so much concerned with memory as with memory’s ability to connect us to others and our capacity for social action.

(cut)

Why does our identity detector place so much emphasis on moral capacities? These aren’t our most distinctive features. Our faces, our fingertips, our quirks, our autobiographies: any of these would be a more reliable way of telling who’s who. Somewhat paradoxically, identity has less to do with what makes us different from other people than with our shared humanity.

However, promising studies have also stirred controversy, with some bioethicists warning that memory-dulling drugs could have profound, unintended consequences for our psyches and our society. The debate is raising tricky questions about what—and who—memory is for. The European Union’s highest court recently ruled that, at least when it comes to the Internet, we all have the “right to be forgotten” for things no longer relevant. Do we also have the right to forget?

The Ethics of Erasing Bad Memories

By​ Cody C. Delistraty
The Atlantic
Originally published May 15, 2014

Here is an excerpt:

“I think we can change some memories without changing fundamentally who we are or how we behave,” said Caplan, who is also the editor of Contemporary Debates in Bioethics. “And even if it does change a little bit of our personal identity, it makes us able to function. We have to understand the plight of those who are prisoners to bad memories, to awful memories, to horrible memories.”

Although, as Caplan said, tragic memories can potentially make us prisoners to ourselves, it is worthwhile to note that our personalities are made up of a delicate interplay of memories. Many experts believe that to disrupt one memory runs the risk of disrupting everything.

“Our memories and our experiences are fundamental to our personhood, to our lives, to everything that makes us who we are,” said Dr. Judy Illes, professor of neurology and Canada research chair in neuoroethics at the University of British Columbia. “When you pull one brick out of the wall of memories, many other memories go with it. Memories are incredibly interlocked with one another.”

Alzheimer's Challenges Notions Of Memory And Identity

By Tania Lombrozo
NPR.org
Originally published on March 4, 2014

Here are some excerpts:

The startling result was that memory wasn't a frontrunner when it came to what sustains someone's "true self." Instead, the winner was morality. A person who had trouble learning new information or forgot childhood memories, for example, was regarded as less fundamentally altered than one who became cruel or selfish, or even one who acquired positive moral traits, such as honesty or forgiveness.

(cut)

The lesson from Zaitchik's research is that while Alzheimer's patients suffer from serious conceptual impairments relative to their healthy counterparts, these impairments aren't uniform across domains. An Alzheimer's patient can be wrong about whether zebras have stripes or a car is alive, but have social and moral reasoning abilities that are relatively intact.

Published in August 2013

Psychologist Elizabeth Loftus studies memories. More precisely, she studies false memories, when people either remember things that didn't happen or remember them differently from the way they really were. It's more common than you might think, and Loftus shares some startling stories and statistics, and raises some important ethical questions we should all remember to consider.

Scientists, Practitioners Don't See Eye to Eye On Repressed Memory

Science Daily
Originally published December 13, 2013

Skepticism about repressed traumatic memories has increased over time, but new research shows that psychology researchers and practitioners still tend to hold different beliefs about whether such memories occur and whether they can be accurately retrieved.

The findings are published in Psychological Science, a journal of the Association for Psychological Science.

"Whether repressed memories are accurate or not, and whether they should be pursued by therapists, or not, is probably the single most practically important topic in clinical psychology since the days of Freud and the hypnotists who came before him," says researcher Lawrence Patihis of the University of California, Irvine.

According to Patihis, the new findings suggest that there remains a "serious split in the field of psychology in beliefs about how memory works."

Neuroscience and the law

Nature Reviews Neuroscience

New insights into the neural processes that underlie cognition and behaviour have led to discussions about the relevance of these discoveries for the criminal justice system. Conversely, laws can influence neuroscience, for example, with regard to psychoactive drugs and stem cell research. Nature Reviews Neuroscience presents a series of articles that explore the interaction between neuroscience and the law.

Why Don’t Cops Believe Rape Victims?

Brain science helps explain the problem—and solve it.

Here are some excerpts:

This is rape culture in action. It puts the burden of proving innocence on the victim, and from Steubenville, Ohio, to Notre Dame and beyond, we’ve seen it poison cases and destroy lives. But science is telling us that our suspicions of victims, the ones that seem like common sense, are flat-out baseless. A number of recent studies on neurobiology and trauma show that the ways in which the brain processes harrowing events accounts for victim behavior that often confounds cops, prosecutors, and juries.

These findings have led to a fundamental shift in the way experts who grasp the new science view the investigation of rape cases—and led them to a better method for interviewing victims. The problem is that the country’s 18,000 law enforcement agencies haven’t been converted. Or at least, most aren’t yet receiving the training to improve their own interview procedures. The exception, it turns out, is the military. Despite its many failings in sexual assault cases, it has actually been at the vanguard of translating the new research into practical tools for investigating rape.

(cut)

This is why, experts say, sexual assault victims often can’t give a linear account of an attack and instead focus on visceral sensory details like the smell of cologne or the sound of voices in the hallway. “That’s simply because their brain has encoded it in this fragmented way,” says David Lisak, a clinical psychologist and forensic consultant who trains civilian and military law enforcement to understand victim and offender behavior.
