When someone is lying to you personally, you may be able to see what they're doing.
- A study uses motion-capture to assess the physical interaction between a liar and their victim.
- Liars unconsciously coordinate their movements to their listener.
- The more difficult the lie, the more the coordination occurs.

Credit: Duck Soup (1933), Universal Pictures<p>The tell? Someone who is lying to your face is likely to copy your motions. The trickier the lie, the truer this is, according to experiments described in the study.</p><p>The researchers offer two possible explanations, both of which have to do with cognitive load. In a <a href="https://www.scimex.org/newsfeed/telling-a-really-big-lie-turns-us-into-copycats" target="_blank">press release</a>, the authors note that "Lying, especially when fabricating accounts, can be more cognitively demanding than truth telling."</p><p>The first hypothesis is that when a liar is lying, their brain is simply too occupied with the subterfuge to pay any attention to the control of physical movements. As a result, the unconscious part of the liar's brain controlling movements defaults to the easiest course of action available: It simply imitates the motions of the person they're lying to.</p><p>The second possibility is that the liar's cognitive load deprives a liar of sufficient bandwidth to devise a clever, effective physical strategy. Instead, while lying, their attention is so laser-focused on their listener's reaction that the liar unconsciously parrots it.</p>

Credit: Niels/Adobe Stock<p>The phenomenon is referred to as "nonverbal coordination," and there is some existing evidence in deception research that it does occur when someone is under a heavy cognitive load. However, that evidence is based on observations of specific body parts and doesn't comprehensively capture whole-body behavior, and little research has mutually tracked both parties' movements in a lying scenario.</p><p>Nonetheless, say the authors, "Nonverbal coordination is an especially interesting cue to deceit because its occurrence relies on automatic processes and is therefore more difficult to deliberately control."</p><p>To track nonverbal coordination, pairs of participants in the study's two experiments were outfitted with motion-capture devices Velcroed to their wrists, heads, and torsos before being seated facing each other across a low table.</p><p>In the first experiment, a dynamic time-warping algorithm analyzed participants movements as they ran through exercises in which one individual told the truth, and then told increasingly difficult lies. In the second experiment, listeners were given instructions that influenced the amount of attention they paid to the liar's movements.</p><p>The researchers found "nonverbal coordination increased with lie difficulty." They also saw that this increase "was not influenced by the degree to which interviewees paid attention to their nonverbal behavior, nor by the degree of interviewer's suspicion. Our findings are consistent with the broader proposition that people rely on automated processes such as mimicry when under cognitive load."</p>
Mirroring<p>There is, it must be said, a third possible reason that a liar copies their target's behavior: Maybe liars are subconsciously reinforcing their credibility with their victims using "mirroring."</p><p>As Big Think readers and anyone familiar with the art of persuasion knows, copying another person's actions is called "mirroring," and it's a way to get someone else to like you. Our brains have "<a href="https://bigthink.com/mind-brain/mirror-neurons-smiling" target="_self">mirror neurons</a>" that respond positively when someone imitates our actions. The result is something called "<a href="https://imaginehealth.ie/the-psychology-of-mirroring/" target="_blank">limbic synchrony</a>." <a href="https://www.scienceofpeople.com/mirroring/" target="_blank" rel="noopener noreferrer">Deliberately mirroring</a> a companion's movements is an acknowledged sales technique.</p><p>So, how can you tell when mirroring signifies a lie and not benign interpersonal salesmanship? There is an overlap, of course — lying is one form of persuasion, after all. Perhaps the smartest response is to simply take mirroring as a signal that close attention is warranted. No need to automatically shout "<a href="https://64.media.tumblr.com/7a549060a9b05fc0a94d50dfe0bcbd9e/tumblr_n24teywDbO1tv5oaqo1_250.gifv" target="_blank">liar!</a>" when someone copies you. Just step back a little mentally and listen a bit more carefully to what your companion is saying.</p>
The newly discovered galaxies are 62x bigger than the Milky Way.
- Two recently discovered radio galaxies are among the largest objects in the cosmos.
- The discovery implies that radio galaxies are more common than previously thought.
- The discovery was made while creating a radio map of the sky with a small part of a new radio array.
An extremely active galaxy<p> <br> </p><p>Radio galaxies are galaxies with extremely active central regions, known as nuclei, which shine incredibly brightly in some part of the electromagnetic spectrum. They are known for emitting large jets of ionized matter into intergalactic space at speeds approaching that of light. They are related to quasars and blazars. It is thought that supermassive black holes are the energy source that make these galaxies shine so brightly. </p><p>What makes these two galaxies (known as MGTC J095959.63+024608.6 and MGTC J100016.84+015133.0) so interesting is their size. Only 831 similar, "giant radio galaxies" are known to exist. As study co-author Dr. Matthew Prescott explains, these are particularly large even for <a href="https://www.forbes.com/sites/jamiecartereurope/2021/01/18/we-just-found-two-mysterious-galaxies-62-times-bigger-than-our-milky-way-say-scientists/?sh=76edf29c2892" target="_blank" rel="noopener noreferrer">giants</a>:</p><p>"These two galaxies are special because they are amongst the largest giants known, and in the top 10 percent of all giant radio galaxies. They are more than two mega-parsecs across, which is around 6.5 million light-years or about 62 times the size of the Milky Way. Yet they are fainter than others of the same size."</p><p>The smaller of the two is just over two megaparsecs across, roughly six and a half million light-years. The larger is almost another half megaparsec larger than <a href="http://www.sci-news.com/astronomy/giant-radio-galaxies-09266.html" target="_blank">that</a>. <br></p><p>Exactly how these things get to be so massive remains a mystery. Some have proposed that they are ejecting matter into unusually empty space, allowing for the jet to expand further, though some evidence contradicts this. The most commonly suggested idea is that they are simply much, much older than the previously observed radio galaxies, allowing more time for expansion to occur.</p>
How does this change our understanding of the universe?<p> While exciting and impressive on their own, the findings also suggest that there are very many more of these giant galaxies than previously supposed. If you were going off the previous estimates for how typical these galaxies are, then the odds of finding these two would be 1 in 2.7×10<sup>6. </sup>This suggests that there must be more, given that the alternative is that the scientists were impossibly lucky. </p><p> In the study, the researchers also apply this reasoning to smaller versions of these galaxies, saying:</p><p> "While our analysis has considered only enormous (>2 Mpc) objects, if radio galaxies must grow to reach this size, then we may expect to similarly uncover in our data previously undetected GRGs with smaller sizes."</p><p> Exactly how common radio galaxies and turn out to be remains to be seen. Still, it will undoubtedly be an exciting time for radio astronomy as new telescopes are turned skywards to search for them.</p>
How did they find them?<iframe width="730" height="430" src="https://www.youtube.com/embed/c1ZW3nVfe5A" frameborder="0" allow="accelerometer; autoplay; clipboard-write; encrypted-media; gyroscope; picture-in-picture" allowfullscreen></iframe><p> The new galaxies were discovered by the amusingly named <a href="https://www.sarao.ac.za/gallery/meerkat/" target="_blank" rel="noopener noreferrer">MeerKAT</a> radio telescope in South Africa during the creation of a new radio map of the sky. The MeerKAT is the first of what will soon be the <a href="https://en.wikipedia.org/wiki/Square_Kilometre_Array" target="_blank" rel="noopener noreferrer">Square Kilometre Array</a> of telescopes, which will span several countries in the southern hemisphere and make even more impressive discoveries in radio astronomy possible. </p>
Daydreaming can be a pleasant pastime, but people who suffer from maladaptive daydreamers are trapped by their fantasies.
Maladaptive daydreaming<img type="lazy-image" data-runner-src="https://assets.rebelmouse.io/eyJhbGciOiJIUzI1NiIsInR5cCI6IkpXVCJ9.eyJpbWFnZSI6Imh0dHBzOi8vYXNzZXRzLnJibC5tcy8yNTUwMjgyMy9vcmlnaW4uanBnIiwiZXhwaXJlc19hdCI6MTY0OTUxNzc3Nn0.yVIUGnZl6VnJhfevESkBpb1TEvwKrHcLtobwNJV55HI/img.jpg?width=1245&coordinates=0%2C63%2C0%2C63&height=700" id="713cf" class="rm-shortcode" data-rm-shortcode-id="e2d24a66284b3aa58ad16b66c135dc9d" data-rm-shortcode-name="rebelmouse-image" data-width="1245" data-height="700" />
One maladaptive dreamer spent hours a day dreaming he was a powerful man who could solve the world's problems.
(Photo: Pixabay)<p>Daydreaming is an indulgence of the mind and imagination, one provided courtesy of the <a href="https://www.sciencedirect.com/topics/neuroscience/default-mode-network#:~:text=The%20default%20mode%20network%20(DMN,and%20Exercise%20Psychology%20Research%2C%202016" target="_blank">default mode network</a>, a network of interacting brain regions that is active even when the conscious mind is not. But like so many of life's indulgences—wine, steak dinners, video games, and even <a href="https://www.healthline.com/health-news/why-too-much-exercise-can-be-bad-042514" target="_blank">exercise</a>—too much daydreaming can be harmful to our well-being. When daydreaming crosses that threshold, it can be considered maladaptive.</p><p>This disorder was first identified by <a href="https://haifa.academia.edu/EliSomer" target="_blank">Eli Somer</a>, a professor of clinical psychology at the University of Haifa, School of Social Work, in <a href="https://link.springer.com/article/10.1023/A:1020597026919" target="_blank" rel="noopener noreferrer">a 2002 paper</a>. That paper looked to six patients in a trauma center whose daydreaming habits replaced human interactions or interfered with their standard life functions, such as going to school or holding down a job. </p><p>Since then, other case studies have looked at <a href="https://www.healthline.com/health/mental-health/maladaptive-daydreaming#:~:text=Maladaptive%20daydreaming%20is%20a%20psychiatric,life%20events%20trigger%20day%20dreams." target="_blank" rel="noopener noreferrer">maladaptive daydreamers</a> and compiled a list of potential symptoms. These include vivid, richly-detailed daydreams; abnormally long daydreaming sessions; daydreams triggered by real-life events; daydreaming sessions that interrupt sleep; and repetitive motions or whisperings while daydreaming. On average, one study reported, maladaptive daydreamers spend <a href="https://bigthink.com/bps-research-digest/people-with-maladaptive-daydreaming-spend-an-average-of-four-hours-a-day-lost-in-their-imagination" target="_self">four hours a day</a> housed in their imaginations.</p><p>"This is not like rehearsing a conversation that you might have with a boss," <a href="https://www.cnn.com/2016/12/30/health/maladaptive-daydreaming-feature/index.html" target="_blank" rel="noopener noreferrer">Somer told CNN</a>. "This is fanciful, weaving of stories. It produces an intense sense of presence."</p><p>While such symptoms are common, though not comprehensive or guaranteed, how maladaptive daydreams manifest are naturally individual to the dreamers. <a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC6426361/" target="_blank" rel="noopener noreferrer">In one case study</a>, researchers analyzed the diary of a man codenamed "Peter." Peter described investing as many as 14 hours a day online. The news and images he happened upon would trigger related fantasies. For example, he may envision himself as a multimillionaire genius who could prevent bad news from occurring or self-insert himself into the power fantasies of superhero movies or police procedurals for hours at a time.</p><p>"When I felt this pain as a child, I started imagining how things could be different. I created stories which never happened. To suppress that pain I would hug my pillow or quilt, thinking I was being comforted by someone else," Peter wrote.</p><p>In an interview with CNN, Cordellia Rose described her maladaptive daydreaming like a drug and noted that her daydreams developed into intricate storylines that could last for years. These stories proved so distracted that she was unable to complete everyday tasks such as driving lessons.</p><p>"You get hooked on it, because it can be like an action movie in your head that's so gripping that you cannot turn off," Rose told CNN. "This [condition] needs to be public, because these are people suffering, and badly."</p><p>To be clear, maladaptive dreaming is not a <a href="https://www.webmd.com/schizophrenia/guide/what-is-psychosis#1" target="_blank" rel="noopener noreferrer">psychotic disorder</a> like schizophrenia. Daydreamers such as Peter and Rose are aware that their fantasies are as unreal as they may be unrealistic. Because of this, many maladaptive dreamers understand the difficulties they face and the real-life losses they have endured for the sake of their fantasies. </p>
More research needed<span style="display:block;position:relative;padding-top:56.25%;" class="rm-shortcode" data-rm-shortcode-id="6fdb8ca5dcc87c58b441d9c7cd766f35"><iframe type="lazy-iframe" data-runner-src="https://www.youtube.com/embed/vI7b4_-MA8g?rel=0" width="100%" height="auto" frameborder="0" scrolling="no" style="position:absolute;top:0;left:0;width:100%;height:100%;"></iframe></span><p>Researchers don't have a <a href="https://www.medicalnewstoday.com/articles/319400" target="_blank" rel="noopener noreferrer">standard diagnosis or treatment for maladaptive daydreaming</a> because they aren't yet sure it's a unique psychological condition. Maladaptive daydreaming has not been included in the Diagnostic and Statistical Manual of Mental Disorders, Fifth Edition—blessedly abbreviated as the DMS-5—the definitive book on mental disorders. To date, there isn't enough evidence to determine if maladaptive daydreaming is a separate condition or a manifestation of an already listed disorder.</p><p>Somer has developed a <a href="https://www.sciencedirect.com/science/article/abs/pii/S1053810015300611" target="_blank" rel="noopener noreferrer">14-point scale</a> to help people determine whether they are experiencing maladaptive-daydreaming symptoms, but the results only indicate whether an individual should seek help. They provide no formal diagnosis.</p><p>Also, maladaptive daydreaming is often expressed alongside other conditions, such as anxiety disorders, <a href="https://www.psychiatryadvisor.com/home/topics/anxiety/ptsd-trauma-and-stressor-related/high-prevalence-of-maladaptive-daydreaming-among-patients-with-dissociative-disorders/" target="_blank" rel="noopener noreferrer">dissociative disorders</a>, attention deficit disorders, and obsessive-compulsive disorders. And the researchers of Peter's case study noticed a striking similarity between his condition and those with <a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3164585/" target="_blank" rel="noopener noreferrer">behavioral addition response</a>—including analogous responses with preoccupation, mood modification, tolerance, and withdrawal. It may be that maladaptive daydreaming is an expression of these, or other, disorders.</p><p>It's worth noting that similar empirical hurdles exist for other well-known, though not formalized, disorders. Orthorexia, sex addiction, misophonia, internet addiction, and parental alienation syndrome are all <a href="https://www.verywellmind.com/whats-missing-from-the-dsm-4145344#:~:text=This%20diagnosis%20covered%20patients%20who,%22%20or%20%22unspecified%20disorder.%22" target="_blank" rel="noopener noreferrer">likewise absent from the DSM-5</a>. For maladaptive daydreaming and these other conditions, it's simply a case of more evidence and research needed before a determination can be made.</p>
A growing understanding of maladaptive daydreaming<p>The question of labeling is a tricky one—not only from a medical point-of-view but also a prosocial one. Some people find having a recognized condition validating; they feel it promotes social acceptance and makes seeking treatment easier. Others find such labels stigmatizing and restricting.</p><p>But the question of how to label something is an academic one. It isn't to say that the experience doesn't exist. It does, and whether maladaptive daydreaming ultimately enters the DSM-5 or not, awareness is growing. <a href="https://daydreamresearch.wixsite.com/md-research/links" target="_blank">Online communities</a> now exist to give support and spread awareness. And regardless of a condition's presence in the medical literature, if symptoms disrupt work, school, or social lives, help should be sought.</p><p>Thanks to the efforts of psychologists and the community, maladaptive daydreaming, unlike Thurber's literary creation, is no longer "inscrutable to the last." And those who suffer it are no longer relegated to a firing-squad of their own mind but can find they help the need.</p>
