Childhood sleeping problems may signal mental disorders later in life
Chronic irregular sleep in children was associated with psychotic experiences in adolescence, according to a recent study out of the University of Birmingham's School of Psychology.

<p>Sleep is a critical activity in our mental and physical health. <a href="https://www.medicalnewstoday.com/articles/325353#lower-risk-of-heart-disease" target="_blank">Sufficient sleep</a> is necessary for learning, productivity, and emotional regulation. It boosts our energy, improves our performance, and helps us prevent injury, making it an athletic necessity on par with hydration and nutrient intake. <a href="https://www.nhlbi.nih.gov/health-topics/sleep-deprivation-and-deficiency#:~:text=Sleep%20plays%20an%20important%20role,pressure%2C%20diabetes%2C%20and%20stroke." target="_blank">Sleep deprivation</a>, meanwhile, has been linked to an increased risk of stroke, obesity, cardiovascular disease, and <a href="https://www.newscientist.com/article/dn17853-lack-of-sleep-linked-to-alzheimers/" target="_blank">onset dementia</a>. And without it, your <a href="https://www.nih.gov/news-events/nih-research-matters/how-sleep-clears-brain" target="_blank">glymphatic system</a> doesn't have the time to properly scrub your brain of the toxic protein beta-amyloid—meaning your head fills up, literally, with unfiltered daytime gunk.</p><p>For children, sleep is even more cruci</p><p>al. <a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC5440010/" target="_blank">A meta-analysis of ten studies</a> on infant sleep and cognition found a "positive association between sleep, memory, language, executive function, and overall cognitive development." In other words, all the ingredients for a healthy mind and social aptitude. It's so necessary for cognitive development that by age two <a href="https://www.sleepfoundation.org/articles/children-and-sleep#:~:text=The%20rhythms%20begin%20to%20develop,his%20or%20her%20childhood%20asleep." target="_blank">a child will spend more time asleep</a> than awake. In total, 40 percent of our childhoods are spent mapping our personal dreamlands.</p><p>But <a href="https://jamanetwork.com/journals/jamapsychiatry/fullarticle/2767298" target="_blank">a recent study</a> in JAMA Psychiatry suggests the obverse is also true. Poor sleep routines, chronically disrupted sleep, and other <a href="http://sleepeducation.org/essentials-in-sleep/parasomnias/overview-and-facts" target="_blank">parasomnias</a> may have an adverse effect on children's mental health later in life.</p>
A time for sleep

The study followed the children for more than 13 years. During that time, mothers filled out questionnaires asking about the children's lives. Factors looked at included housing, parenting, nutrition, physical health, mental wellbeing, environmental exposures, and so on. </p><p>The cohort study inquired about sleep routines, sleep duration, and awakening frequency when the children were 6, 18, and 30 months old, and then again at 3.5, 4.8, and 5.8 years. It also assessed mental health in adolescence using semi-structured interviews, such as the Psychosis-Like Symptom Interview.</p><p>"We know that adolescence is a key developmental period to study the onset of many mental disorders, including psychosis or BPD. This is because of particular brain and hormonal changes which occur at this stage," <a href="https://www.birmingham.ac.uk/staff/profiles/psychology/marwaha-steven.aspx" target="_blank">Steven Marwaha</a>, professor of psychiatry at Birmingham and senior author on the study, <a href="https://www.sciencedaily.com/releases/2020/07/200701125431.htm" target="_blank">said in a release</a>. "Sleep may be one of the most important underlying factors—and it's one that we can influence with effective, early interventions, so it's important that we understand these links."</p><p>After compiling the data, the researchers discovered an association between children with irregular sleeping patterns and teenagers with <a href="https://www.mind.org.uk/information-support/types-of-mental-health-problems/psychosis/about-psychosis/" target="_blank">psychotic experiences</a>—that is, episodes when the person perceives reality differently than those around them. Even when depression at 10 years old was considered as a mediating factor, their findings still suggested "a specific pathway between these childhood sleep problems and adolescent psychotic experiences." </p><p>Toddlers with shorter nighttime sleep duration and late bedtimes were likewise associated with a <a href="https://www.nimh.nih.gov/health/topics/borderline-personality-disorder/index.shtml" target="_blank">borderline personality disorder</a>—a disorder marked by a pattern of varying moods, self-images, and behaviors—in their teenage years. Depression at age 10 did not mediate this particular association, suggesting a separate and more specific pathway. </p>A more restful tomorrow
<p>While the sample size was large and mental health was assessed with a validated interview, there nevertheless remain limitations to this data. For starters, sleep habits were based on mothers' reports. Because they came from memory, versus a more direct observation method such as actigraphy, these data may be prone to imperfect recollection and reporting error. There are also many confounders that could be secretly nudging the results, such as family conditions, prenatal medicines, and a host of environmental factors. Finally, <a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC6024884/#:~:text=Sleep%20difficulties%20in%20youth%20with,fear%20of%20dark%20%5B13%5D." target="_blank">the relationship between sleep problems and mental disorders</a> is both complex and two-way.</p><p>As such, the study shows an association between poor childhood sleep later mental disorders but does not prove a causal link. Parents need not worry that a string of nightmares or the eternal struggle settle into bed will be the first ingredients in a witches' brew of debilitating mental disorders. The goal of the study, the researchers point out, is not to create undue worry but improve our ability to recognize the signs of at-risk children and deliver necessary interventions earlier.</p><p>"The results of this study could have important implications for helping practitioners identify children who might be at higher risk for psychotic experiences or BPD symptoms in adolescence, and potentially lead to the design of more effectively targeted sleep or psychological interventions to prevent the onset or attenuate these mental disorders," Isabel Morales-Muñoz, the study's lead researcher, <a href="https://www.healio.com/news/psychiatry/20200702/childhood-sleep-problems-linked-to-adolescent-psychosis-borderline-personality-disorder#:~:text=Sleep%20problems%20during%20early%20childhood,study%20published%20in%20JAMA%20Psychiatry." target="_blank">told Healio Psychiatry</a><u>.</u></p><p>If a parent reading this is worried that their child's sleep patterns are deleterious, the take away should not be despair over an unyielding fate. It should be to seek professional help as soon as possible to begin improving sleep duration and quality. Even if you aren't worried, it's worth remembering that childhood experiences lay the foundation for a lifetime of salubrious sleeping habits. It's so much more than beauty rest.</p>

Women who go to church have more kids—and more help
Want help raising your kids? Spend more time at church, says new study.
06 July, 2020
Pixabay
- Religious people tend to have more children than secular people, but why remains unknown.
- A new study suggests that the social circles provided by regular church going make raising kids easier.
- Conversely, having a large secular social group made women less likely to have children.
<p>When you think about it, religious ritual is kind of strange. People invest time, energy, and resources into pageantry that doesn't appear to produce any immediate return on investment. From an evolutionary standpoint, this doesn't make a ton of sense—we might expect cultures with elaborate, energy-intensive rituals to be less successful than their neighbors who invest their resources elsewhere. </p><p>However, we see religious rituals of various kinds all around the world and across history. Examples can be found in the most enduring empires and the smallest territories. We know of the rituals in both the most impressive cultures and those that merely passed by on the world's stage. The constant presence of religious ceremonies in our history suggests that there is some functionality that more than justifies the upfront costs. Precisely what this functionality is and how it works is increasingly the focus of many studies in the social sciences. </p><p>One such <a href="https://royalsocietypublishing.org/doi/10.1098/rstb.2019.0428#d403693e1" target="_blank">study</a>, published in Philosophical Transactions of the Royal Society B, suggests that the social bonds formed by religious communities provide support that differs from those of secular communities and allows women to have more children without the typical costs of a larger <a href="https://phys.org/news/2020-07-links-religion-parental-non-family-members.html" target="_blank">family</a>. </p>
Be fruitful and multiply
<p>Scientists in the United Kingdom collected data on more than 13,000 mothers and their children. Most of them were religious, but 12 percent were not. The data included information on their church habits, social networks, number of children, and the scores those children achieved on a standardized test.</p><p>In line with previous findings that religious women have more children than secular women in industrialized countries, a connection between at least monthly church attendance and fertility was confirmed. However, religious parents showed they could avoid the pitfalls that having more children can bring. </p><p>Typically, more children in a family leads to reduced cognitive ability and height in each <a href="https://academic.oup.com/ije/article/37/6/1408/729795" target="_blank">child</a>. Some studies find that children do less well in school for each <a href="https://link.springer.com/article/10.1007/s13524-016-0471-0" target="_blank">additional sibling they have</a>. This makes a kind of intuitive sense, as parents with more children would have to divide their time, energy, and resources among more people as families expand. One would expect that the larger families would also lead to things like lower test scores. </p><p>Despite the expectation, the children of religious parents didn't have lower scores on standardized tests. There were small positive relationships between the size of the mother's social network, the number of co-religionists helping out, and the children's test scores. However, this association was small, didn't show up in all of the testings, and was unrelated to other variables. </p> These effects might be explained by the size and helpfulness of the social networks around the more religious. Women who went to church at least once a month had more extensive social networks than those who never go or who attend yearly. These social networks of co-religious people mean that there are more people to turn to for help with child-rearing, a point also demonstrated in the data. The amount of aid women got from their fellow churchgoers was also associated with a higher fertility rate. <br> <br> Conversely, an extensive social network was associated with fewer children for secular women. This finding is in line with <a href="https://journals.sagepub.com/doi/10.1207/s15327957pspr0904_5" target="_blank">previous studies</a> and suggests that the social networks comprised of co-religious individuals differ from those found elsewhere.So, how quickly should I join a local religious group?

Though it might be said the results point towards causation, various alternative interpretations of the data are apparent. The authors note that most religions are explicitly pro-natal. It is possible that religious women have internalized these values and simply choose to have more children than secular women do.</p><p>This idea is similar to a potential interpretation of why large social networks have the opposite effect for secular women. The authors suggest that, in some cases, these more extensive social networks are associated with work and exert an anti-natal influence. Again, the people who build such networks may be people unlikely to have large families under any circumstances.</p><p>However, the researchers' hypothesis endured. The help religious women get from their church-based social networks allows them to have larger families than those who lack these support systems. In some instances, these support systems also prevent the adverse effects of larger families. </p>The community religion offers
<p>As we've mentioned <a href="https://bigthink.com/culture-religion/what-is-secular-humanism" target="_blank">before</a>, religion offers a community, and a community provides social capital. As religion continues to decline in the West, the social bonds of faith communities that used to tie social communities together begin to decay. However, as has been noted by a variety of observers for the last few decades, fewer and fewer new organizations appear ready to replace religion as a source of community in our lives.</p><p>While many different organizations might offer social support that religion once provided the whole of western society, this study shows that different social circles can differently affect the people in them. This finding must be considered by those trying to find new communities to join or the authors of future research. </p><p>The community offered by religious groups provides real benefits to those who join them. As this study shows, having the support network religious community offers allows some parents to avoid pitfalls that bedevil those lacking similar support. It suggests that previous studies demonstrating that group ritual offers benefits like increased amounts of <a href="https://journals.sagepub.com/doi/10.1177/0956797612472910" target="_blank">group trust</a> and <a href="https://journals.sagepub.com/doi/10.1177/1069397103037002003" target="_blank">cooperation</a> are onto something and that those benefits have a variety of applications. </p><p>While this study is not without its blind spots, it offers a strong starting point for further investigations into the nature of ritual in our modern lives and how local support networks remain vital in our increasingly globalized world. </p>

Education vs. learning: How semantics can trigger a mind shift
The word "learning" opens up space for more people, places, and ideas.
06 July, 2020
- The terms 'education' and 'learning' are often used interchangeably, but there is a cultural connotation to the former that can be limiting. Education naturally links to schooling, which is only one form of learning.
- Gregg Behr, founder and co-chair of Remake Learning, believes that this small word shift opens up the possibilities in terms of how and where learning can happen. It also becomes a more inclusive practice, welcoming in a larger, more diverse group of thinkers.
- Post-COVID, the way we think about what learning looks like will inevitably change, so it's crucial to adjust and begin building the necessary support systems today.

How Hemingway felt about fatherhood
Parenting could be a distraction from what mattered most to him: his writing.
05 July, 2020
Ernest Hemingway Holding His Son 1927 (Wikimedia Commons)
Ernest Hemingway was affectionately called “Papa," but what kind of dad was he?
<p>In my role as Associate Editor of the <a href="https://www.hemingwaysociety.org/hemingway-letters-project" target="_blank">Hemingway Letters Project</a>, I spend my time investigating the approximately 6,000 letters sent by Hemingway, 85% of which are now being published for the first time in a multivolume series. <a href="https://www.cambridge.org/us/academic/subjects/literature/literary-texts/letters-ernest-hemingway-19321934-volume-5?format=HB&isbn=9780521897372" target="_blank">The latest volume</a> – the fifth – spans his letters from January 1932 through May 1934 and gives us an intimate look into Hemingway's daily life, not only as a writer and a sportsman, but also as a father.</p><p>During this period, Hemingway explored the emotional depths of fatherhood in his fiction. But his letters show that parenting could be a distraction from what mattered most to him: his writing. </p>
<h2>'No alibis' in the writing business</h2><p>Hemingway had three sons. His oldest, John – nicknamed "Bumby" – was born to Ernest and his first wife, Hadley, when Ernest was 24 years old. He had Patrick and Gregory with his second wife, Pauline.</p><p>Hemingway initially approached fatherhood with some ambivalence. In her 1933 memoir "<a href="http://gutenberg.net.au/ebooks06/0608711.txt" target="_blank">The Autobiography of Alice B. Toklas</a>," Gertrude Stein recalls that one evening Hemingway came to visit and "announced…with great bitterness" that he was "too young to be a father."</p><p>As the fifth volume of letters opens in January 1932, Hemingway is trying to finish "<a href="https://books.google.com/books/about/Death_in_the_Afternoon.html?id=Wn69QsdwDlQC" target="_blank">Death in the Afternoon</a>," his nonfiction account of bullfighting, in a household with a six-week-old baby, a three-year-old who ingests ant poison and nearly dies, a wife still recovering from a C-section, along with all the quotidian problems of home ownership, from a leaky roof to faulty wiring.</p><p><a href="https://images.theconversation.com/files/342233/original/file-20200616-23227-ywfum4.jpg?ixlib=rb-1.1.0&q=45&auto=format&w=1000&fit=clip" target="_blank"><img alt="" src="https://images.theconversation.com/files/342233/original/file-20200616-23227-ywfum4.jpg?ixlib=rb-1.1.0&q=45&auto=format&w=754&fit=clip"></a></p><p>Ernest Hemingway and Pauline Pfeiffer Hemingway, with Gregory, Patrick and Bumby in Key West, 1933. (Princeton University Library, Author provided)</p><p>Hemingway explained to his mother-in-law, Mary Pfeiffer, that if his latest book fell short, he couldn't simply take readers aside and say, "But you ought to see what a big boy Gregory is…and you ought to see our wonderful water-work system and I go to church every Sunday and am a good father to my family or as good as I can be."</p><p>There are "no alibis" in the writing business, Hemingway continued, and "a man is a fool" to allow anything, even family, to interrupt his work. "Taking refuge in domestic successes," he added, "is merely a form of quitting."</p><p>For Hemingway, work didn't simply entail sitting at a desk and writing. It also included the various adventures he was famous for – the <a href="https://www.simonandschuster.com/books/Hemingway-on-Fishing/Ernest-Hemingway/9781476716411" target="_blank">fishing</a>, <a href="https://www.pbs.org/hemingwayadventure/africa.html" target="_blank">hunting</a>, traveling and socializing with the people he met along the way. Though he would teach the boys to fish and shoot when they were older, when they were very young he didn't hesitate to leave them with nannies or extended family for long stretches of time.</p><p>This separation was <a href="https://www.kirkusreviews.com/book-reviews/john-hemingway/strange-tribe/" target="_blank">particularly hard</a> on the youngest, Gregory, who, from a very young age, was left for months in the care of Ada Stern, a governess who lived up to her last name. Patrick sometimes joined his parents on their travels or stayed with other relatives. Bumby, the oldest, divided his time between his father and his mother in Paris. The children's lives were so peripatetic that at the Letters Project we maintain a spreadsheet to keep track of their whereabouts at any given time.</p>
<h2>'Papa' explores fathers and sons in his fiction</h2><p>However, it would not be accurate to say that Hemingway did not care about his children. In the latest volume of letters, three are addressed to Patrick, two of them decorated with circled dots, a Hemingway family tradition called "toosies," which represented kisses.</p><p><img alt="" src="https://images.theconversation.com/files/342482/original/file-20200617-94044-1rk64fc.jpg?ixlib=rb-1.1.0&q=45&auto=format&w=754&fit=clip"></p><p>In his letters to his kids, Hemingway would sometimes draw dots called 'toosies,' which represented kisses. (Princeton University Library, Author provided)</p><p>In Hemingway's fiction, we can see the depth of that paternal feeling, and in his letters, the domestic moments that inspired him.</p><p>In November 1932, with his two youngest sons ill with whooping cough and being cared for by their mother at their grandparents' home in Arkansas, Hemingway postponed a trip to New York to stay in Key West with Bumby.</p><p>"He is a good kid and a good companion," Hemingway wrote his editor, Maxwell Perkins, "but I do not want to drag him around the speakies [bars] too much."</p><p>That same month Hemingway worked on the story of a father and son traveling together that would become "<a href="https://en.wikipedia.org/wiki/Fathers_and_Sons_(short_story)" target="_blank">Fathers and Sons</a>" in the collection "<a href="https://books.google.com/books/about/Winner_Take_Nothing.html?id=Bc8C0Hb9B5YC" target="_blank">Winner Take Nothing</a>." It's one of the only stories in which Nick Adams – a semi-autobiographical recurring character – is portrayed as a parent, and the reflective, melancholy piece was written just three years after Hemingway's own father <a href="https://www.jstor.org/stable/2926355?seq=1" target="_blank">had died by suicide</a>.</p><p>In the story, Nick is driving along a stretch of highway in the countryside with "his son asleep on the seat by his side" when he starts thinking about his father.</p><p>Nick recalls many details about him: his eyesight, good; his body odor, bad; his advice on hunting, wise; his advice about sex, unsound. He reflects on viewing his father's face after the undertaker had made "certain dashingly executed repairs of doubtful artistic merit."</p>
<p>Nick is surprised when his son starts to speak to him because he "had felt quite alone" even though "this boy had been with him." As if reading his father's thoughts, the boy wonders, "What was it like, Papa, when you were a little boy and used to hunt with the Indians?'"</p><p>Hemingway's letters show that another story in the collection, "<a href="http://crmsl.weebly.com/uploads/6/3/1/4/63143381/a_day%E2%80%99s_wait_by_ernest_hemingway.pdf" target="_blank">A Day's Wait</a>," was inspired by Bumby's bout with influenza in the fall of 1932. It is a seemingly lighthearted story about a young boy's misunderstanding of the differences between the centigrade and Fahrenheit scales of temperature. Like Bumby, the protagonist, "Schatz" – one of Bumby's other nicknames, a term of endearment in German – attends school in France but is staying with his father when he becomes ill. Schatz had learned at school that no one can survive a temperature of 44 Celsius, so, unbeknownst to his father, he spends the day waiting to die of his fever of 102 Fahrenheit.</p><p>But there is more to this story than the twist. "You don't have to stay in here with me, Papa, if it bothers you," the boy tells him. "It doesn't bother me," his father replies. He unwittingly leaves his son to believe, for an entire day, not only that the boy is going to die, but that his death is of no importance to his father.</p><p>In this slight story – one of those stories he told Perkins was written "absolutely as they happen" – we find an unexpected Hemingway hero in the form of a nine-year-old boy who bravely faces death alone.</p><p>Though he once wrote that he wanted "Winner Take Nothing" to make "a picture of the whole world," Hemingway also seemed to understand that no one ever truly knows the subjective experience of another, not even a father and son.</p><p><a href="https://theconversation.com/profiles/verna-kale-408674" target="_blank">Verna Kale</a>, Associate Editor, The Letters of Ernest Hemingway and Assistant Research Professor of English, <em><a href="https://theconversation.com/institutions/pennsylvania-state-university-1258" target="_blank">Pennsylvania State University</a></em></p><p>This article is republished from <a href="https://theconversation.com/" target="_blank">The Conversation</a> under a Creative Commons license.

Changing the way we grade students could trigger a wave of innovation
How students apply what they've learned is more important than a letter or number grade.
01 July, 2020
- Schools are places where learning happens, but how much of what students learn there matters? "Almost all of our learning happens through experience and very little of it actually happens in these kinds of organized, contrived, constrained environments," argues Will Richardson, co-founder of The Big Questions Institute and one of the world's leading edupreneurs.
- There is a shift starting, Richardson says, in terms of how we look at grading and assessments and how they have traditionally dictated students' futures. Consortiums like Mastery.com are pushing back on the idea that what students know can be reflected in numbers and letter grades.
- One of the crucial steps in changing how things are done is first changing the narratives. Students should be assessed on how they can apply what they've learned, not scored based on what they know.
