In fact, Wells’s studies found that sequential lineups slashed the rate of false positives considerably. His first study showed a drop in incorrect accusations  43 to 17 percent. Sequential lineups also slightly increased the number of missed identifications

two and a half years later, the questionnaire was given a second time to the same students.

It was then that R. T. recalled, with absolute confidence, her dorm-room experience.

She didn’t know any details of what had happened,

We don’t really remember an uneventful day the way that we remember a fight or a first kiss.

Her hope is to understand how, exactly, emotional memories behave at all stages of the remembering process: how we encode them, how we consolidate and store them, how we retrieve them.

When it comes to the central details of the event, like that the Challenger exploded, they are clearer and more accurate. But when it comes to peripheral details, they are worse. And our confidence in them, while almost always strong, is often misplaced.

Phelps has combined Neisser’s experiential approach with the neuroscience of emotional memory to explore how such memories work, and why they work the way they do.

A key element of emotional-memory formation is the direct line of communication between the amygdala and the visual cortex.

Within the brain, memories are formed and consolidated largely due to the help of a small seahorse-like structure called the hippocampus; damage the hippocampus, and you damage the ability to form lasting recollections.

Memory for the emotional scenes was significantly higher, and the vividness of the recollection was significantly greater.

hat is, if you were shocked when you saw animals, your memory of the earlier animals was also enhanced. And, more important, the effect only emerged after six or twenty-four hours: the memory needed time to consolidate.

o, if memory for events is strengthened at emotional times, why does everyone forget what they were doing when the Challenger exploded?

The strength of the central memory seems to make us confident of all of the details when we should only be confident of a few.

Our misplaced confidence in recalling dramatic events is troubling when we need to rely on a memory for something important—evidence in court, for instance

After reviewing the evidence, the committee made several concrete suggestions to changes in current procedures, including “blinded” eyewitness identification

standardized instructions to witnesses, along with extensive police training in vision and memory research as it relates to eyewitness testimony, videotaped identification, expert testimony early on in trials about the issues surrounding eyewitness reliability, and early and clear jury instruction on any prior identifications

, the rodent displayed a heightened fear response, although no foot shock had ever been given in that location. The mice eventually became conditioned to the false memory, and would freeze in Box A even in the absence of pulsing light.

“The brain mechanisms for forming and recalling the false memories are not distinguishable from those underlying genuine memories,” said Tonegawa.

hypothesized that a similar mechanism could be behind the formation of false memories in humans and said the findings underscore the problematic nature of eyewitness testimony in court proceedings.

“We hope this kind of research will reinforce the need to look at eyewitness testimony carefully,” said Tonegawa, “so that innocent people will not be incriminated.”

Tonegawa said he thinks that false memories with positive connotations likely form in the same way—a hypothesis he hopes to test with future experiments. In addition, given that false memories appear robust enough to compete with real memories, Tonegawa said he plans to investigate the factors that affect the relative strengths of the two types of memory.

an eyewitness had drawn widespread attention and touched off protests by Black community members, who called for the officer to be fired.

The protests were set against the backdrop of the trial of Derek Chauvin, one of four former Minneapolis police officers who have been charged in the killing of George Floyd last May.

Minneapolis police officers had been helping their suburban counterparts, who had stopped a suspect in the carjacking, when a group of residents approached and protested that the officers had the wrong person in custody, the eyewitness video showed

The events were recorded on video by an eyewitness and came as residents had been protesting another teenager’s arrest in connection with what police said was a “violent felony carjacking.”

Psychologists say that starting when they are infants and young children, people become attuned to the key facial features and characteristics of the those around them. Whites often become accustomed to focusing on differences in hair color and eye color. African-Americans grow more familiar with subtle shadings of skin color.

Minorities tend to be better at cross-race identification than whites, Professor Meissner said, in part because they have more extensive and meaningful exposure to whites than the other way around.

Professor Malpass, who has trained police officers and border patrol agents, urges law enforcement agencies to make sure black or Hispanic officers are involved when creating lineups of black and Hispanic suspects. And he warns of the dangers of relying on cross-racial identifications from eyewitnesses, who can be fallible.

“I don’t think we should be offended,” he said. “This is really an ability issue.

Depending on the study, you might get as many as 50 percent of people falling for the suggestion and developing a complete or partial false memory.

Is it the power of suggestion from a therapist that creates these "memories," then? EL: Yes, a lot of the cases involve suggestive psychotherapy. But you don't absolutely need the therapy. You can get suggestion from the culture and the environment, like when somebody turns on Oprah and sees one of these repressed-memory therapists talking, then believes this has happened to them.

How do you plant these memories? EL: We use a "false feedback" technique. We gather a whole bunch of data from you, about your personality, thoughts about different foods, all kinds of things. Later, we hand you this computerized profile, which reveals certain things that probably happened when you were a child. In the middle of the list is, say, that you got sick eating strawberry ice cream. We give you false feedback about your data, and then encourage you to elaborate and imagine. Later we ascertain whether you have a belief that it happened to you. Then we offer you a choice from all these different foods. In that example we found that participants didn't want strawberry ice cream as much.

bad governments, bad people, they don't have requirements of conduct. When we recently published a study about planting false memories among U.S. soldiers, I was worried we were putting out a recipe for how you can do horrible things to somebody and then wipe their memory away.

Is there any way to distinguish a false memory from a real one? EL: Without independent corroboration, little can be done to tell a false memory from a true one.

Growing evidence suggests that gloomy moods improve key types of thinking and behavior, Forgas asserts in a new review paper aptly titled “Don’t worry, be sad!” For good evolutionary reasons, positive and negative moods subtly recruit thinking styles suited to either benign or troubling situations,

Alternatively, good moods trigger a loose mode of thought conducive to creativity and seeing the big picture. Happiness signals that a situation is safe, or at least not immediately threatening,

Whether good or bad, moods are relatively low-intensity, background feelings that can last for anywhere from a few minutes to the whole day. A person may feel somewhat good or bad, happy or sad, without knowing why or even being aware of such moods.

On “good” days, he reasoned, everything just felt right without any past triumphs coming to mind. On “bad” days, life felt lousy in the moment, without any tragic memories returning for an encore.

Individuals aren’t slaves to their moods, Schwarz cautions. A sad person can think outside the box if necessary, say, to solve problems at work. And a happy person can accurately fill out tax forms or complete other detail-heavy tasks.

Moods provide surprisingly keen insights into one’s environment, the team concluded.

By embracing their moods, superior forecasters gained unconscious access to a vast amount of learned information that informed their predictions, Pham speculated.

Many emotion theorists now agree that negative moods direct attention to tasks at hand and promote analytical thinking, whereas positive moods broaden attention and prompt original thinking. Researchers in a field dubbed “positive psychology” have put a lot of recent focus on exploring how happiness profits mind and body.

Sad moods also improve eyewitness memory, apparently by lowering the tendency to incorporate false and misleading details into accounts of what was observed. In a 2005 study in the Journal of Experimental Social Psychology, college students witnessed a staged altercation between a lecturer and a woman who angrily interrupted the talk.

Sad moods can also make first impressions of others more reliable,

Sad folks took longer to read and rate the essays than happy and neutral participants did. That’s probably because feeling sad fostered a more careful appraisal of essays and photos, Forgas suggests. As a result, he proposes, sad volunteers largely rejected the stereotype of philosophers as tweedy, professorial men, helping to minimize the halo effect.

In these experiments, moods were induced either by having participants watch happy or sad film clips or by falsely telling volunteers that they had scored extremely well or poorly on a test of spatial abilities.

In both conditions, raters determined that sad volunteers communicated more information relevant to the movie scenes and less unrelated information than the other two groups did, especially the happy folks. Those in a sad mood were especially good at keeping accounts brief, clear and to the point.

Moods were induced after participants watched movie clips but before they described the scenes, ensuring that the clips didn’t sway their manipulated moods.

Sad feelings may influence communication differently in situations where conversation

But moods may not engage specific mental strategies as proposed

If these findings hold up, happy and sad moods simply signal whether or not to change one’s current thinking style, Huntsinger says, rather than indicating whether to adopt an analytical or playful thinking style. Researchers have yet to test which of these two possibilities best explains mood-related behaviors.

much remains unknown about precisely how moods influence thought

“Since my debut on television in 1979, I have been an eyewitness to the many changes in technology, society, and how we communicate. I am one who embraces change, and celebrates the higher quality of life we enjoy now thanks to this progress.

I realize the instant communication platforms we enjoy now do have some negatives that are troubling. Just a few examples in recent days…”

“This is a lenticular cloud. They have always been around, and quite frankly aren’t that unusual (although it is an anomaly to see one away from a mountain range). The one thing that is different today is that almost everyone has a camera phone, and almost everyone shares pictures of weather events. You didn’t see these often in earlier decades because technology didn’t allow it. Lenticular clouds are nothing new. But, yes, they are cool to see.”

This age of misinformation can lead to dangerous consequences, and promote an agenda, he warns.

“The Houston flooding is a great example. We are being told this is unprecedented’… Houston is ‘under water… and it is due to manmade global warming. “Yes, the flooding in Houston yesterday was severe, and a serious threat to life and property. A genuine weather disaster that has brought on suffering.

this was not ‘unprecedented.’ Flooding from Tropical Storm Allison in 2001 was more widespread, and flood waters were deeper. There is no comparison.”

“Those on the right, and those on the left hang out in ‘echo chambers,’ listening to those with similar world views refusing to believe anything else could be true

“Everyone knows the climate is changing; it always has, and always will. I do not know of a single ‘climate denier.’ I am still waiting to meet one.

“The debate involves the anthropogenic impact, and this is not why I am writing this piece. Let’s just say the Houston flood this week is weather, and not climate, and leave it at that.”

Spann lays much of the blame on the mainstream media and social media “hype and misinformation.”

“They will be sure to let you know that weather events they are reporting on are unprecedented,’ there are ‘millions and millions in the path,’ it is caused by a ‘monster storm,’ and ‘the worst is yet to come since these events are becoming more ‘frequent.’

“You will never hear about the low tornado count in recent years, the lack of major hurricane landfalls on U.S. coasts over the past 10 years, or the low number of wildfires this year. It doesn’t fit their story.

never let facts get in the way of a good story…. there will ALWAYS be a heat wave, flood, wildfire, tornado, tyhpoon, cold wave, and snow storm somewhere. And, trust me, they will find them, and it will probably lead their newscasts

that memory is not a video recorder [but that] it’s a constructive activity that is in many ways accurate but prone to interesting errors and distortions. It’s the constructive side of memory that is most relevant to historians.

Is it the case then that our memories constantly change every time we access them?

That certainly can happen depending on how you recount a memory. What you emphasize. What you exaggerate. What you don’t talk about. All of those things will shape and sculpt the memory for future use. Certainly the potential is there.

Research on memory shows that the more distant in time the event, the more prone to inaccuracy the memory. There are several experiments when subjects recorded impressions of an event soon afterward, then a year later and then a few years later, and the memory changed.Yes. It’s not that the information is lost but, as the memory weakens, you become more prone to incorporating other kinds of information or mixing up elements of other events. This has been seen, for example, in the study of flashbulb memories. Where were you when Kennedy was shot? Where were you when you heard about 9/11?

Isn’t there a tendency to add details or information that may make the story more convincing or interesting later?Yes. That’s more a social function of memory. It may be that you draw on your general knowledge and probable information from your memory in a social context where there may be social demands that lead you distort the memory.

What are the different memory systems?

What is the difference between working memory and permanent memory?Working memory is really a temporary memory buffer where you hold onto information, manipulate information, use it, and it’s partly a gateway to long-term memory and also a buffer that you use when you’re retrieving information from long-term memory and that information temporarily resides in working memory, so to speak.

Your discussion of the testimony of White House Counsel John Dean about Watergate is illuminating. There was a perception that Dean had a photographic memory and he testified in rich detail about events. Yet later studies of White House tape recordings revealed that he was often inaccurate.

He was perceived because of all the detail with which he reported events and the great confidence to be something analogous to a human tape recorder. Yet there was interesting work done by psychologist Ulric Neisser who went back and analyzed what Dean said at the hearings as compared to available information on the White House taping system and basically found many and significant discrepancies between what Dean remembered and what was actually said. He usually had the gist and the meaning and overall significance right, but the exact details were often quite different in his memory than what actually was said.

That seems to get into the area of false memories and how they present problems in the legal system.We know from DNA exonerations of people wrongfully convicted of crimes that a large majority of those cases -- one of the more recent estimates is that in the first 250 cases of 2011 DNA exonerations, roughly 70 to 75 percent of those individuals were convicted on the basis of faulty eyewitness memory.

One of the interesting recent lines of research that my lab has been involved in over the past few years has been looking at similarities between what goes on between the brain and mind when we remember past events on the one hand and imagine events that might occur in the future or might have occurred in the past. What we have found, particularly with brain scanning studies, is that you get very similar brain networks coming online when you remember past events and imagine future events, for example. Many of the same brain regions or network of structures come online, and this has helped us understand more why, for example, imagining events that might have occurred can be so harmful to memory accuracy because when you imagine, you’re recruiting many of the same brain regions as accessed when you actually remember. So it’s not surprising that some of these imagined events can actually turn into false memories under the right circumstances.

One reasonably well accepted distinction involves episodic memory, the memory for personal experience; semantic memory, the memory for general knowledge; and procedural memory, the memory for skills and unconscious forms of memory.Those are three of the major kinds of memory and they all have different neural substrates.

One of the points from that Ross Perot study is that his supporters often misremembered what they felt like at the time he reported he had dropped out of the race. The nature of that misremembering depended on their state at the time they were remembering and what decisions they had made about Perot in the interim affected how they reconstructed their earlier memories.Again, that makes nicely the point that our current emotions and current appraisals of a situation can feed back into our reconstruction of the past and sometimes lead us to distort our memories so that they better support our current emotions and our current selves. We’re often using memories to justify what we currently know, believe and feel.

memory doesn’t work like a video camera or tape recorder.That is the main point. Our latest thinking on this is the idea that one of the major functions of memory is to support our ability to plan for the future, to imagine the future, and to use our past experiences in a flexible way to simulate different outcomes of events.

flexibility of memory is something that makes it useful to support this very important ability to run simulations of future events. But that very flexibility might be something that contributes to some of the memory distortion we talked about. That has been prominent in the last few years in my thinking about the constructive nature of memory.

The historian Daniel Aaron told his students “we remember what’s important.” What do you think of that comment?I think that generally holds true. Certainly, again, more important memories tend to be more significant with more emotional arousal and may elicit “deeper processing”, as we call it in cognitive psychology

Loftus’s research has already rattled our justice system, which relies so heavily on eyewitness testimonies.

“It’s so powerful when somebody tells you something and they have a lot of detail,” Loftus said. “Especially when they express emotion. To just say, ‘Oh my god it must be true.’ But all those characteristics are also true of false memories, particularly the heavily rehearsed ones that you ruminate over. They can be very detailed. You can be confident. You can be emotional. So you need independent corroboration.”

When later asked about the events, the superior memory subjects indicated the erroneous facts as truth at about the same rate as people with normal memory.

been able to successfully convince ordinary people that they were lost in a mall in their childhood, pointed out that false memory recollections also occur among high profile people.

All memory, as McGaugh explained, is colored with bits of life experiences. When people recall, “they are reconstructing,” he said. “It doesn't mean it’s totally false. It means that they’re telling a story about themselves and they’re integrating things they really do remember in detail, with things that are generally true.”

“puzzling why (Highly Superior Autobiographical Memory) individuals remember some trivial details, such as what they had for lunch 10 years ago, but not others, such as words on a word list or photographs in a slideshow,” Patihis and colleagues noted in the PNAS study. “The answer to this may be that they may extract some personally relevant meaning from only some trivial details and weave them into the narrative for a given day.”

For all of us, the stronger the emotion attached to a moment, the more likely those parts of our brains involved in memory will become activated.

“Why did evolution do that?” McGaugh said. “Because it was essential for our survival.

We now know animals are likely susceptible to memory distortions too, as MIT researchers recently were able to successfully plant false memories in mice.

“We’re all creating stories. Our lives are stories in that sense.”

“but you as the writer have the obligation to get as close to the truth as you possibly can,” Meyer said

The mind and its memory do not just record and retrieve information and experiences, but also infer, fill in gaps, and construct, wrote Bryan Boyd wrote in On the Origin of Stories. “Episodic memory’s failure to provide exact replicas of experiences appears to not be a limitation of memory but an adaptive design.”

we should also learn to check that tendency to just immediately assume rape accusers are lying, a tendency that’s so out of control that many people believe or at least entertain the possibility that 30 women could somehow be conspiring to lie together for reasons unknown.

Memory does not work like that. It does not work like a video camera or a DVR.

hypnosis-induced testimony is problematic.

If your goal is to get people to get to their - to the actual memory for the actual scene in question, if they didn't encode it at the time, it's probably not there to be retrieved.

The judge felt Clay should not be treated as a child. This decision was based in part on the outcome of a Rorschach test where a person is asked to look at an inkblot and describe what he sees.

They're not listening to the truth. They don't accept the truth. And when I was growing up, they had this notions about kids should be seen and not heard. And I was being seen, but I was not being heard.

the Justice Department's manual for federal prosecutors says that, in rare cases, forensic hypnosis can aid investigations.

according to the National Registry of Exonerations, there have been at least 10 cases of wrongful conviction that involve hypnosis. Clay would still be in prison today, but a few years ago, he was granted parole and Lisa Kavanaugh helped get his conviction thrown out.

Fred Clay's codefendant, James Watson, is still serving out his sentence. Watson's guilty verdict was based in part on the same problematic eyewitness testimonies that put Clay in prison. Watson is now seeking to have his conviction overturned. Shankar Vedantam, NPR News.

Microscopic organisms don’t make for good alien villains, but our chances of discovering extraterrestrial microbial life seem better than encountering advanced alien civilizations, Varnum says. In recent years, more and more scientists have begun to suspect that microbes may exist on moons in our solar system, in the subsurface oceans of Europa and Enceladus and the methane lakes of Titan.

In every case, the text-analysis software showed that people, journalists and non-journalists alike, seemed to exhibit more positive than negative emotions in response to news of extraterrestrial microbes.

In general, media mentions and their predictive abilities are imperfect measures. Text-analysis software itself has some gaps; the program can’t, for example, detect sarcasm.

“A lot of worldviews, both religious and secular, have shown themselves to be pretty flexible,” Varnum says. “The Catholic Church eventually made peace with a heliocentric solar system, right?”

In 2004, Navy fighter jet pilots operating from the USS Nimitz aircraft carrier reported seeing UFOs off the coast of San Diego. And, more recently, other military pilots flying with the USS Theodore Roosevelt in the Atlantic made similar claims. The news of those accounts became public knowledge from a story in the New York Times and a new miniseries on the History Channel.

Some accounts simply arose from nothing more than the fevered imaginations of UFO enthusiasts.

An eyewitness can be an unreliable source of information and, in the case of something as extraordinary as the observation of alien spacecraft, pedestrian evidence simply won’t do. As Carl Sagan often said, extraordinary claims require extraordinary evidence.

Even though there were multiple observations of multiple phenomena, what is missing is multiple reports of the same phenomenon. It would be hasty to link these independent observations together.

But I’m going to need much better evidence than what we have so far. In the meantime, let’s keep an eye on these reports. You know… just in case.
