    Why are people interested in virtual reality and what can it tell us about who we are and what we might become in a digital world?

    “As an artist, it’s a question I’ve been asking for decades,” said artist and media arts professor Marilene Oliver. “Now with virtual reality, when we really are completely immersed in the digital, I wanted to ask that question.”

    In addition to her teaching work, Oliver is the co-curator of an art exhibit at the University of Alberta’s Fine Arts Building gallery called Know Thyself As a Virtual Reality.

    “It’s based on a Greek maxim: Nosce te Ipsum, which was used in the Temple of Apollo in Delphi. In that time, it was: ‘To know your place within a social hierarchy.’

    “Later you find it in anatomical engravings, where it’s: ‘To know thyself as a divine work of God.’ And now, the more we’re becoming digital, the more we’re creating these huge data sets of everything we do, we now need to know ourselves, I believe, as digital objects and subjects,” Oliver explained. “This is what we are called to do now to understand ourselves.”

    There are seven artworks that use virtual reality to explore different aspects of data and the digital aspects of human life. The works brought together many different disciplines including fine art, radiology, engineering, music, digital humanities and computing science.

    Oliver explains one focus of the exhibit as: “Can we find a way to visually communicate what we’re becoming as digital beings?”

    That’s where the virtual reality comes in. Donning a headset and hand controls, a person is immersed in data — the information, how it looks, sounds and feels — and can interact with it.

    “In one of the projects that I was part of, called My Data Body, we try to create a body which you can take apart and dissect,” Oliver explained.

    “It has many different data bodies in it. It has my MRI scan, all my social media data, my Google data, banking data, my data cookies and it’s put it in kind of this vessel that you can then take apart in an attempt to try and see it, to try and hold it, because how else can we see all this data that we’re generating?”

    “aAron Munson has made a work called Where Are You? and that makes us think about how social media is changing the way our brain works and where we place our attention,” Oliver said.

    Munson compared fMRI scans of their brain: neutral, after meditating and after using social media. People can use the VR headset to experience the three different brain scans.

    “Chelsey Campbell has made a piece that is very peaceful and restful,” Oliver said. “It makes us think about how much work we constantly feel we need to be doing all the time. She stands against that and has created a very quiet space where you should just lay and enjoy the beauty of the room.”

    In the VR experience, the user is transported to a domestic bedroom space.

    “We have another piece by Lisa Mayes, which actually isn’t with an MRI scan, but with her DNA data,” Oliver said.

    “She sent off a sample to Ancestry and found out about her family history. She talks about how the scientific data recording somehow legitimized all the conversations that had been had in her family about her ancestral roots, which come from Ireland, from France, Scotland and Ghana.”

    The Nearest Window

    “We have another artist who is presenting bodies that aren’t normally present in digital works, which are MTurk workers,” Oliver said.

    Artist Dana Dal Bo looks at Mechanical Turk (MTurk) crowdsourcing.

    “If you don’t know, Amazon has a service which allows you to employ, for a very little amount, this invisible labour,” Oliver explained. “People do surveys, they do a lot of AI processing … labelling data sets.”

    The artist asked MTurk’s anonymous workers to take a picture of what they could see out of their nearest window and send it to her.

    A mirror with no reflection

    “We have the artist Nicholas Hertz, who’s made a work which is really about the experience of being scanned and the sense of feeling that data is taken from you and then not recognized, not really recognizing the results of those data,” Oliver said.

    Using VR, audience members can experience MR scans, the sounds and feelings they produce and the images they create.

    Hertz also questions just how “non-invasive” this procedure is and what it’s like to see yourself reflected in this way.

    “We tried to create an exhibition which has many different perspectives,” Oliver said. “Maybe it makes people think: ‘OK, what would I do? How would I treat my data if I were making a VR artwork?”

    She hopes the art makes people think personally and relationally.

    “I hope firstly that they will think about all the bodies of data they have and how responsible they are for it and also how they interact with others.”

  • Genome studies uncover a new branch in fungal evolution

    Genome studies uncover a new branch in fungal evolution

    [ad_1]

    Newswise — About 600 seemingly disparate fungi that never quite found a fit along the fungal family tree have been shown to have a common ancestor, according to a University of Alberta-led research team that used genome sequencing to give these peculiar creatures their own classification home.

    “They don’t have any particular feature that you can see with the naked eye where you can say they belong to the same group. But when you go to the genome, suddenly this emerges,” says Toby Spribille, principal investigator on the project and associate professor in the Department of Biological Sciences.

    “I like to think of these as the platypus and echidna of the fungal world.”

    Spribille, Canada Research Chair in Symbiosis, is referring to Australia’s famed Linnaean classification system-defying monotremes — which produce milk and have nipples, but lay eggs — that were the source of debate as to whether they were even real.

    “Though nobody thought our fungi were fake, it’s similar because they all look totally different.”

    Using DNA-based dating techniques, the team found that this new class of fungi, called Lichinomycetes, descended from a single origin 300 million years ago, or 240 million years before the extinction of dinosaurs. 

    David Díaz-Escandón, who performed the research as part of his PhD thesis, explains that these “oddball” fungi were previously sprinkled across seven different classes — a high-level grouping that in animals would be equivalent to the groups called mammals or reptiles. 

    Working with a team of researchers from seven countries to get material from the fungi, he sequenced 30 genomes and found that all classes but one descended from a single origin.

    “They were classified, but they were classified into such different parts of the fungal side of the tree of life that people never suspected they were related to each other,”  says Díaz-Escandón. 

    These fungi include forms as varied as earth tongues — eerie tongue-shaped fungi that shoot up vertically out of the ground — beetle gut microbes, and a fungus found in tree sap in northern Alberta. They also include some unusual lichens that survive in extreme habitats such as South America’s Atacama Desert, the driest non-polar desert in the world.

    “What is really fascinating is that despite these fungi looking so different, they have a lot in common at the level of their genomes,” says Spribille. “Nobody saw this coming.”

    Based on their genomes, which are small compared with those of other fungi, the team predicts that this group of fungi depend on other organisms for life.

    “Their small genomes mean this class of fungi have lost much of their ability to integrate some complex carbohydrates,” said Spribille. “When we go back to look at each of these fungi, suddenly we see all of them are in a kind of symbiosis.”

    He notes the new research will be important to the broader study of fungal evolution, specifically how fungi inherit important biotechnological features such as enzymes that break down plant matter.

    The new group also could be a source of new information about past fungal extinctions. 

    “We think it’s likely that the diversity we see today is just the tip of the iceberg that survived. And we don’t have that many examples of this kind of thing in fungi.”

    The research appears online in the journal Current Biology.

  • You’ve Probably Seen Yourself in Your Memories

    You’ve Probably Seen Yourself in Your Memories

    [ad_1]

    Pick a memory. It could be as recent as breakfast or as distant as your first day of kindergarten. What matters is that you can really visualize it. Hold the image in your mind.

    Now consider: Do you see the scene through your own eyes, as you did at the time? Or do you see yourself in it, as if you’re watching a character in a movie? Do you see it, in other words, from a first-person or a third-person perspective? Usually, we associate this kind of distinction with storytelling and fiction-writing. But like a story, every visual memory has its own implicit vantage point. All seeing is seeing from somewhere. And sometimes, in memories, that somewhere is not where you actually were at the time.

    This fact is strange, even unsettling. It cuts against our most basic understanding of memory as a simple record of experience. For a long time, psychologists and neuroscientists did not pay this fact much attention. That has changed in recent years, and as the amount of research on the role of perspective has multiplied, so too have its potential implications. Memory perspective, it turns out, is tied up in criminal justice, implicit bias, and post-traumatic stress disorder. At the deepest level, it helps us make sense of who we are.

    The distinction between first- and third-person memories dates back at least as far as Sigmund Freud, who first commented on it near the end of the 19th century. Not for another 80 years, though, did the first empirical studies begin fleshing out the specifics of memory perspective. And it was only in the 2000s that the field really started picking up steam. What those early studies found was that third-person memories were far less unusual than once thought. The phenomenon is associated with a number of mental disorders, such as depression, anxiety, and schizophrenia, but it is not merely a symptom of pathology; even among healthy people, it is quite common.

    Just how common is tricky to quantify. Peggy St. Jacques, a psychology professor at the University of Alberta who studies perspective in memory, told me that roughly 90 percent of people report having at least one third-person memory. For the average person, St. Jacques estimates, on the basis of her research, that about a quarter of memories from the past five years are third-person. (At least a couple of papers have found that women tend to have more third-person memories than men do, but a third study turned up no statistically significant difference; on the whole, research on possible demographic disparities is scant.) In certain rare cases, people may have only third-person memories. As you try to recall your own, be warned that things can get confusing fast. Perhaps you can call to mind early-childhood scenes that you picture from a third-person perspective. But it’s hard to know whether these are genuine memories translated from the first person to the third person, or third-person scenes constructed from stories or photographs. To some people, third-person memories are second nature; to others, they sound like science fiction.

    Why any given memory gets recalled from one perspective rather than the other is the result of a whole bunch of intersecting factors. People are more likely to remember experiences in which they felt anxious or self-conscious—say, when they gave a presentation in front of a crowd—in the third person, St. Jacques told me. This makes sense: When you’re imagining how you look through an audience’s eyes in the moment, you’re more likely to see yourself through their eyes at the time of recall. Researchers have also repeatedly found that the older a memory is, the more likely you are to recall it from the third person. This, too, is fairly intuitive: If first-person recollection is the ability to adopt the position—and inhabit the experience—of your former self, then naturally you’ll have more trouble seeing the world the way you did as a 6 year old than the way you did last week. The tendency for older memories to be translated into the third person may also have to do with the fact that the more distant the memory is, the less detail you’ll likely have, and the less detail you have, the less likely you are to be able to reassume the vantage point from which you originally witnessed the scene, David Rubin, a Duke University psychology professor who has published dozens of papers on autobiographical memory, told me.

    Less intuitive, perhaps, is the reverse: People are able to recall a scene in greater detail when they’re asked to take a first-person perspective than when they’re asked to take a third-person perspective. “Sometimes in a courtroom, an eyewitness to a holdup might be asked to recall what happened from the perspective of the clerk,” St. Jacques told me. But if her research is any indication, such tactics may blur rather than sharpen the witness’s memory. “Our research suggests that might actually be more likely to make the memory less vivid, make the eyewitness less likely to remember the specifics.”

    Even without an examiner’s instructions, such an eyewitness might be predisposed to recall the robbery in the third person: Researchers have found that people often translate traumatic or emotionally charged memories out of the first person. This may be because first-person memories tend to elicit stronger emotional reactions at the time of recall, and by taking a third-person perspective, we can distance ourselves from the painful experience, Angelina Sutin, a psychologist at Florida State University, told me. It may also be a function of the information at our disposal. In charged situations, Rubin said, people tend to zero in on the object of their anger or fear. Take the bank-robbery scenario: The police “want the teller to describe the person who’s robbing them, and instead he describes in great detail the barrel of the gun pointed at his head.” He can’t remember much beyond that. And so, lacking the information necessary to situate himself in his original perspective, he floats.

    This distancing effect has some fairly mind-bending potential applications, none more so, perhaps, than to the problem of near-death experiences. For many years, philosophers and psychologists have documented instances of people reporting that, in moments of trauma, they felt as though they were floating outside—usually above—their body. Rubin points out, however, that such reports are not in-the-moment descriptions but after-the-fact accounts. So he has a controversial idea: What in retrospect seems like an out-of-body experience may in fact be only the trauma-induced translation of a first-person memory into a third-person memory, one so compelling that it deceives you into thinking the experience itself occurred in the third person. The recaller, in this theory, is like a person peering through a convex window, mistaking a distortion of the glass for a distortion of the world.

    Traumatic dissociations are dramatic but by no means isolated cases of what Rubin calls the “constructive nature of the world.” In a 2019 review article on memory perspective, St. Jacques noted that shifting your vantage and fabricating an entirely new scene rely on the same mental processes occurring in the same regions of the brain. So similar are recollecting the past and projecting into the future that some psychologists lump them into a single category: “mental time travel.” Both are acts of construction. The distinction between memory and imagination blurs.

    At some level, people generally understand this, but rarely do we get so incontrovertible an example as with third-person memories. If you and a friend try to recall the decor at the restaurant where you got dinner last month, you might find that you disagree on certain points. You think the wallpaper was green, your friend thinks blue, one of you is wrong, and you’re both sure you’re right. With third-person memories, though, you know the memory is distorted, because you could not possibly have been looking at yourself at the time. If, without even realizing it, you can change something so central as the perspective from which you view a memory, how confident can you really be in any of the memory’s details?

    In this way, third-person memories are sort of terrifying. But shifts in perspective are more than mere deficiencies of memory. In her lab at Ohio State University, the psychologist Lisa Libby is investigating the relationship between memory perspective and identity—that is, the way shifts in our memory play a role in how we make sense of who we are. In one experiment, Libby asked a group of female undergraduates whether they were interested in STEM. The students then participated in a science activity, some in a version designed to be engaging, others in a version designed to be boring. Afterward, when she surveyed the undergrads about how they’d found the exercise, she instructed some to recall it from a first-person perspective and others from a third-person perspective. The first-person group’s answers corresponded to how interesting the task really was; the third-person group’s corresponded to whether they’d said they liked STEM in the initial survey.

    Libby’s takeaway: Each type of memory seems to have its own function. “One way to think about the two perspectives is that they help you represent … two different components of who you are as a person,” Libby told me. Remembering an event from a first-person perspective puts you in an experiential frame of mind. It helps you recall how you felt in the moment. Remembering an event from a third-person perspective puts you in a more narrative frame of mind. It helps you contextualize your experience by bringing it in line with your prior beliefs and fitting it into a coherent story. Memory is the—or at least a—raw material of identity; perspective is a tool we use to mold it.

    Maybe the most interesting thing about all of this is what it suggests about the human proclivity for narrative. When we shift our memories from one perspective to another, we are, often without even realizing it, shaping and reshaping our experience into a story, rendering chaos into coherence. The narrative impulse, it seems, runs even deeper than we generally acknowledge. It is not merely a quirk of culture or a chance outgrowth of modern life. It’s a fact of psychology, hardwired into the human mind.
