How can we train ourselves to face life’s challenges? How do we stay connected in a world full of distractions and alienation?</p> <p><img class="migrated-asset" src="/sites/default/files/JV%20Pic%202019.jpg" alt>Such questions are at the centre of the Ƶ’s&nbsp;<strong>John Vervaeke</strong>’s academic work – not to mention&nbsp;<a href="https://www.youtube.com/channel/UCpqDUjTsof-kTNpnyWper_Q">his successful&nbsp;YouTube channel</a> – and have never been more relevant than during&nbsp;COVID-19.</p> <p>&nbsp;</p> <p>An assistant professor, teaching stream, in the&nbsp;department of psychology&nbsp;in the Faculty of Arts &amp; Science and the&nbsp;cognitive science&nbsp;program at University College, Vervaeke (left) recently launched a new series of videos in response to the pandemic. Every weekday morning, he livestreams a short lesson about meditation followed by a brief silent meditation period.</p> <p>Arts &amp; Science writer <strong>Jovana Jankovic </strong>recently spoke to Vervaeke about mindfulness and meditation, particularly during times of stress and anxiety.</p> <hr> <p><strong>What are the biggest misconceptions about meditation?</strong></p> <p>One is that meditation is about achieving a kind of relaxation akin to sleepiness – that it should make your body and mind cloudy and dull, and your consciousness fade away. That’s not the kind of relaxation you want in meditation. You want a type of relaxation that enhances your sense of stability and your sensitivity. Meditation is not a vacation, it’s an education.</p> <p>The other misconception is that you’re not meditating unless your mind goes wide open and blank. That’s exactly the wrong attitude. Every time you catch yourself in distraction and come back to your meditative focus, you’re actually building the mindfulness muscle. It’s like doing reps in weight training.</p> <p><strong>Why did you decide to do this series of morning sessions during the pandemic?</strong></p> <p>I think our culture in general is going through a meaning crisis in which we lack a sense of how we are connected to ourselves, to each other, to the world; how much we matter, how much we’re in touch with reality, how much we’re overcoming self-deception, how much we’re affording wisdom.</p> <p>If the meaning crisis is a fundamental sense of disconnection, the COVID crisis certainly exacerbates that. People feel very disconnected from their life, disconnected from the world, disconnected from each other. So, while it’s good to develop a mindfulness practice in general, I think it’s especially pertinent right now.</p> <p><strong>You say that frequency of meditation is more important than length of sessions. Could you tell us more about that?</strong></p> <p>Continuity of practice is more important than quantity,&nbsp;but&nbsp;that doesn’t mean the quantity is irrelevant. If you’re trying to learn something new and you just stay inside your comfort zone, you’re not challenging yourself, which is how learning happens.</p> <p>So, when you’re sitting for meditation, if you only sit as long as it’s comfortable, you don’t get into what psychologists call the “zone of proximal development.”&nbsp;That’s where you learn new things. You have to keep sitting when it’s challenging and you have to use the principles and practices you’re taught to keep going.</p> <p>But if you say, "Well, I can’t sit for a full 15 minutes, so I won’t sit at all," that will erode your practice. If you can honestly say to yourself that you can only sit for five minutes, then sit for five minutes. It’s not always sufficient, but it’s certainly better than nothing.</p> <p><strong>What are some quick and easy tips for beginners who are just trying meditation?</strong></p> <p>People try to get into a posture that is free from unpleasant sensations or discomfort. But you’ll never get there. I’ve been meditating for 20 years and I’ve never found such a thing. That’s really important to remember.</p> <p>And centring your mind doesn’t mean just focusing your attention. It means stepping back and looking at your mind rather than looking through it. The metaphor I use is my glasses: I look through my glasses all day long, but if they are full of gunk, what I have to do is actually step back and look at them.</p> <p>You need to try to do the same thing with your mind: Step back and look at its patterns and processes. And don’t frame meditation as instantly getting your mind to go blank. You have to learn to sit until your mind settles.</p> <p>Finally, you need both a meditative practice and a contemplative practice. We use those terms as if they’re synonyms, but they’re not. To go back to my analogy, if meditation is like stepping back and looking at your glasses, how do you know if you’ve spotted a distortion or a defect in your glasses? You have to put them back on, right?</p> <p>If you put them back on and you see better, that’s a contemplative aspect of the practice. Can you see through what was previously illusion into reality? This relates to work I did with my former student <strong>Leo Ferraro</strong>, who was a TA and an alumnus in the cognitive science program as well as my co-author for a book chapter called “Reformulating the Mindfulness Construct.”</p> <p><strong>Cognitive science is perhaps not as well-known as psychology or neuroscience. What is it?</strong></p> <p>In many ways, cognitive science is close to philosophy and particularly ancient philosophy like that of Socrates and Plato. It’s about studying the mind and its relationship to reality in a very comprehensive manner.</p> <p>In the modern world, we have a discipline that studies the brain and that’s neuroscience. We have computer science, which studies artificial intelligence – that’s about systems that can solve problems and do information processing. Or we have psychologists, who study human behaviour. We might go to a linguist who studies how we communicate through grammar and syntax with each other. Or we might be concerned with culture, so we might go to an anthropologist for that.</p> <p>Those things are not isolated. They interact with and affect each other. And cognitive science gets all of those other disciplines to insightfully talk to each other as they study the mind in their different ways. It’s sort of a very powerful bridging discourse between them.&nbsp;&nbsp;</p> <p><iframe allow="accelerometer; autoplay; encrypted-media; gyroscope; picture-in-picture" allowfullscreen frameborder="0" height="422" src="https://www.youtube.com/embed/AdL9Yd0lB_k" width="750"></iframe></p> </div> <div class="field field--name-field-news-home-page-banner field--type-boolean field--label-above"> <div class="field__label">News home page banner</div> <div class="field__item">Off</div> </div> Thu, 30 Apr 2020 19:38:29 +0000 Christopher.Sorensen 164333 at U of T study uses algorithms to predict how word meanings change over time /news/u-t-study-uses-algorithms-predict-how-word-meanings-change-over-time <span class="field field--name-title field--type-string field--label-hidden">U of T study uses algorithms to predict how word meanings change over time </span> <div class="field field--name-field-featured-picture field--type-image field--label-hidden field__item"> <img loading="eager" srcset="/sites/default/files/styles/news_banner_370/public/2018-02-20-nina%27s%20story-resized.jpg?h=afdc3185&amp;itok=78ImE4ev 370w, /sites/default/files/styles/news_banner_740/public/2018-02-20-nina%27s%20story-resized.jpg?h=afdc3185&amp;itok=YNpJfXlZ 740w, /sites/default/files/styles/news_banner_1110/public/2018-02-20-nina%27s%20story-resized.jpg?h=afdc3185&amp;itok=AM-T1bKu 1110w" sizes="(min-width:1200px) 1110px, (max-width: 1199px) 80vw, (max-width: 767px) 90vw, (max-width: 575px) 95vw" width="740" height="494" src="/sites/default/files/styles/news_banner_370/public/2018-02-20-nina%27s%20story-resized.jpg?h=afdc3185&amp;itok=78ImE4ev" alt="Photo of Yang Xu "> </div> <span class="field field--name-uid field--type-entity-reference field--label-hidden"><span>noreen.rasbach</span></span> <span class="field field--name-created field--type-created field--label-hidden"><time datetime="2018-02-20T16:32:34-05:00" title="Tuesday, February 20, 2018 - 16:32" class="datetime">Tue, 02/20/2018 - 16:32</time> </span> <div class="clearfix text-formatted field field--name-field-cutline-long field--type-text-long field--label-above"> <div class="field__label">Cutline</div> <div class="field__item"> Assistant Professor Yang Xu is the first joint faculty appointment to computer science and University College’s cognitive science program (photo by Nina Haikara)</div> </div> <div class="field field--name-field-author-reporters field--type-entity-reference field--label-hidden field__items"> <div class="field__item"><a href="/news/authors-reporters/nina-haikara" hreflang="en">Nina Haikara</a></div> </div> <div class="field field--name-field-topic field--type-entity-reference field--label-above"> <div class="field__label">Topic</div> <div class="field__item"><a href="/news/topics/our-community" hreflang="en">Our Community</a></div> </div> <div class="field field--name-field-story-tags field--type-entity-reference field--label-hidden field__items"> <div class="field__item"><a href="/news/tags/cognitive-science-program" hreflang="en">Cognitive Science Program</a></div> <div class="field__item"><a href="/news/tags/computer-science" hreflang="en">Computer Science</a></div> <div class="field__item"><a href="/news/tags/research-innovation" hreflang="en">Research &amp; Innovation</a></div> <div class="field__item"><a href="/news/tags/university-college" hreflang="en">University College</a></div> </div> <div class="clearfix text-formatted field field--name-body field--type-text-with-summary field--label-hidden field__item"><p>Using the <em>Historical Thesaurus of English</em> as a dataset, which dates back nearly 1,000 years to the period of Old English, researchers at the University of California, Berkeley, Lehigh University and the Ƶ have developed an&nbsp;algorithm to demonstrate how words evolve.&nbsp;</p> <p>“If you look at the history of a word, meanings of that word tend to shift or extend over time,” says <strong>Yang Xu</strong>, an assistant professor in the department of computer science and University College’s cognitive science program. “The question is: Why is this happening? How is it happening? And whether there are computational algorithms we can leverage to make predictions about the historical development of word meanings.”</p> <p><a href="http://www.pnas.org/content/early/2018/02/16/1714730115">The researchers published their findings on Feb. 19 </a>in the <em>Proceedings of the National Academy of Sciences</em> (PNAS).</p> <p>As Xu explains, the word “face” was used to reference a body part. It then extended to include senses of facial expressions, such as “smiley face” or “funny face”. Later, the meaning covers novel senses such as the surface of an object, “face of a table” or “face of a cube”. But it doesn’t end there. “Face” can be used in remote context, such as “face danger” or “face risks”&nbsp;–&nbsp; resulting in a web or network of meanings.</p> <p>“The [algorithm’s] prediction is that a word should connect closely to related meanings in the space available – similar to finding nearest neighbours in semantic space – resulting in a chain that efficiently links novel meanings to the existing meanings of a word.”</p> <h3><a href="http://gicr.utoronto.ca/support-the-report/">Interested in publicly funded research in Canada? Learn more at U of T’s #supportthereport advocacy campaign</a></h3> <p>“[What] we didn't know from the past, is how this chaining process can be implemented computationally and tested at a broad scale.”</p> <p>Xu says an ongoing study will explore the basis of chaining across a diverse array of languages, to see whether it can explain some recurring patterns, like why do many languages use the same word to describe “fire” and “flame”, and to leverage current digital resources to predict word usage over time. The work could have further implications in the area of natural language processing, training computers to understand novel word usage accurately.</p> <h3><a href="http://www.pnas.org/content/early/2018/02/16/1714730115">Read the research in PNAS</a></h3> <p>“A potential research direction is the machine interpretation of novel word usages such as those in non-literal expressions,” says Xu. “If I say 'grasp’ I can refer to ‘grasping an object’ versus ‘grasping an idea’. Humans understand this usage fairly quickly, even though it appears novel. Understanding these phenomena would require the development of computational tools that would go beyond the algorithms of chaining.”</p> <p>U of T’s undergraduate <a href="http://www.uc.utoronto.ca/cognitive-science">cognitive science program</a>, sponsored by University College, merges cross-disciplinary studies in computer science, linguistics, philosophy, psychology and neuroscience, and challenges students on questions of the human mind and its application to machines. Xu, whose earlier graduate work looked at machine learning applications in cognitive neuroscience, is the first joint research appointment, strengthening ties between computer and cognitive sciences.</p> <p>He joins core faculty <strong>Ana Pérez-Leroux</strong>, professor of Spanish and linguistics and the program’s director;&nbsp;<strong>John Vervaeke, </strong>a lecturer in the&nbsp;department of psychology, and Assistant Professor&nbsp;<strong>James John </strong>of the&nbsp;department of philosophy. Xu plans to teach a course on data science in the cognitive sciences.&nbsp;</p> <p>Future research questions for Xu include how children learn language.</p> <p>“I'm curious about the parallels between historical language change and child language acquisition,” says Xu. “For example, a child might use ‘bus’ to refer to a lot of things that move on the road, so I can imagine some sort of chaining mechanism going on there.”</p> <p>“Whether that's necessarily the same as chaining observed in historical language change, we don't know. But I think it opens up new questions that we can explore.”</p> <p>&nbsp;</p> <p>&nbsp;</p> </div> <div class="field field--name-field-news-home-page-banner field--type-boolean field--label-above"> <div class="field__label">News home page banner</div> <div class="field__item">Off</div> </div> Tue, 20 Feb 2018 21:32:34 +0000 noreen.rasbach 129822 at
