What's Going On In Your Child's Brain When You Read Them A Story? : NPR Ed : NPR - 0 views

  •  
    For the study, conducted by Dr. John Hutton, a researcher and pediatrician at Cincinnati Children's Hospital, and someone with an interest in emergent literacy, 27 children around age 4 went into an FMRI machine. They were presented with the same story in three conditions: audio only; the illustrated pages of a storybook with an audio voiceover; and an animated cartoon. While the children paid attention to the stories, the MRI, the machine scanned for activation within certain brain networks, and connectivity between the networks. Here's what researchers found: In the audio-only condition (too cold): language networks were activated, but there was less connectivity overall. "There was more evidence the children were straining to understand." In the animation condition (too hot): there was a lot of activity in the audio and visual perception networks, but not a lot of connectivity among the various brain networks. "The language network was working to keep up with the story," says Hutton. "Our interpretation was that the animation was doing all the work for the child. They were expending the most energy just figuring out what it means." The children's comprehension of the story was the worst in this condition. The illustration condition was what Hutton called "just right".When children could see illustrations, language-network activity dropped a bit compared to the audio condition. Instead of only paying attention to the words, Hutton says, the children's understanding of the story was "scaffolded" by having the images as clues. Most importantly, in the illustrated book condition, researchers saw increased connectivity between - and among - all the networks they were looking at: visual perception, imagery, default mode and language. One interesting note is that, because of the constraints of an MRI machine, which encloses and immobilizes your body, the story-with-illustrations condition wasn't actually as good as reading on Mom or Dad's lap.

Socially isolated people have differently wired brains and poorer cognition - new research - 1 views

  •  
    A 2022 University of Cambridge study conducted by Sahakian, Langley, Chen, et al., and published in the journal _Neurology_, shows that that social isolation is linked to changes in brain structure and cognition - the mental process of acquiring knowledge - it even carries an increased risk of dementia in older adults. Previous research established that brain regions consistently involved in diverse social interactions are strongly linked to networks that support cognition, including the default mode network (which is active when we are not focusing on the outside world), the salience network (which helps us select what we pay attention to), the subcortical network (involved in memory, emotion and motivation) and the central executive network (which enables us to regulate our emotions). This particular study examined how social isolation affects grey matter - brain regions in the outer layer of the brain, consisting of neurons. It investigated data from nearly 500,000 people from the UK Biobank, with a mean age of 57. People were classified as socially isolated if they were living alone, had social contact less than monthly and participated in social activities less than weekly. The study also included neuroimaging (MRI) data from approximately 32,000 people. That data revealed that socially isolated people had poorer cognition, including in memory and reaction time, and lower volume of grey matter in many parts of the brain. These areas included the temporal region (which processes sounds and helps encode memory), the frontal lobe (which is involved in attention, planning and complex cognitive tasks) and the hippocampus - a key area involved in learning and memory, which is typically disrupted early in Alzheimer's disease. We also found a link between the lower grey matter volumes and specific genetic processes that are involved in Alzheimer's disease. Follow-ups with participants 12 years later showed that those who were socially isolated, but not

Facebook, Twitter and other social networks are the new matchmakers. And they're free. - 2 views

  •  
    With studies showing that one-third of married couples started their relationships online, finding romance via URLs is no longer as novel - and creepy - as it seemed when dating sites launched in the mid-1990s. But now the digital aisle to marriage is transforming, moving from dating sites to social networks, where couples say encounters are more revealing and, with witty tweets and thoughtful status updates, more like flirting in the analog world. And they're free.

Online Social Networking and Mental Health - 1 views

  •  
    This article discusses the results of many studies on how social networking affects mental health. Over the past 10 years, online social networking has caused profound changes in the way people communicate and interact. Several studies have indicated that the prolonged use of social networking sites (SNS), such as Facebook, may be related to signs and symptoms of depression. Some authors have also indicated that certain SNS activities might be associated with low self-esteem, especially in children and adolescents. This review focuses on the recent findings regarding the suggested connection between SNS and mental health issues such as depressive symptoms, changes in self-esteem, and Internet addiction.

Social networking sites to help you learn a new language - 1 views

  •  
    Learning a new language used to mean having to sit down with a book or attend a class, or if you were technologically advanced, listen to a language tape. Learning a new language now, however, is much more diverse with online language courses and even social networking sites dedicated to language learning, which seems like a great idea, because social media networking sites are becoming more and more popular.

Stanford technology helps scholars get 'big picture' of the Enlightenment - 0 views

  •  
    "Researchers map thousands of letters exchanged in the 18th century's "Republic of Letters" ... According to Edelstein, "We tend to think of networks as a modern invention, something that only emerged in the Age of Information. In fact, going all the way back to the Renaissance, scholars have established themselves into networks in order to receive the latest news, find out the latest discoveries and circulate the ideas of others." ... "when you have a rich, dense and geographically expansive correspondence network," what exactly puts you at the hub? In other words, are you the leading light because you are a great thinker with provocative ideas? Or are you a good patron who can bring people together? Or is it that "you have goodies to give?""

Thinking Out Loud: How Successful Networks Nurture Good Ideas - 0 views

  •  
    Author Clive Thompson argues, "The fact that so many of us are writing - sharing our ideas, good and bad, for the world to see - has changed the way we think. Just as we now live in public, so do we think in public. And that is accelerating the creation of new ideas and the advancement of global knowledge." Every day, we collectively produce millions of books' worth of writing. Globally we send 154.6 billion emails, more than 400 million tweets, and over 1 million blog posts and around 2 million blog comments on WordPress. On Facebook, we post about 16 billion words. Altogether, we compose some 3.6 trillion words every day on email and social media - the equivalent of 36 million books.* (The entire US Library of Congress, by comparison, holds around 23 million books.) He notes the Internet has spawned a global culture of avid writers, one almost always writing for an audience, and suggests that writing for a real audience helps clarify one's thinking, enhances learning, and arguably, betters writers' organization, ideas, and attention to editing.

Unpacking the Science: How Playing Music Changes the Learning Brain - 2 views

  •  
    This article examines Nadine Gaab's 2014 study which established a connection - in both children and adults - between learning to play an instrument and improved executive functioning, like problem-solving, switching between tasks and focus. The article also cites the research of neuropsychologist Ani Patel, who advances the OPERA theory of music's benefits for learning. Patel notes "music is not an island in the brain cut off from other things, that there's overlap, that's the 'O' of OPERA, between the networks that process music and the networks that are involved in other day-to-day cognitive functions such as language, memory, attention and so forth," he says. "The 'P' in OPERA is precision. Think about how sensitive we are to the tuning of an instrument, whether the pitch is in key or not, and it can be painful if it's just slightly out of tune." That level of precision in processing music, Patel says, is much higher than the level of precision used in processing speech. This means, he says, that developing our brains' musical networks may very well enhance our ability to process speech. "And the last three components of OPERA, the 'E-R-A,' are emotion, repetition and attention," he says. "These are factors that are known to promote what's called brain plasticity, the changing of the brain's structure as a function of experience."

    "Even when daydreaming, there is a tremendous amount of communication happening between different areas in the brain... The fact that these areas are synchronized has led many scientists to presume that they are all part of an interconnected network called a resting-state network. ... that these resting-state networks look essentially normal in people missing the corpus callosum link... [it] highlights the brain's remarkable plasticity... the findings are significant when considering the link between brain connections and autism or schizophrenia."

How the brain reads music: the evidence for musical dyslexia - 0 views

  •  
    While this article primarily addresses the phenomenon of dysmusia, difficulty in reading music, it also talks about the cognitive underpinnings of music reading. In the brain, reading music is a widespread, multi-modal activity, meaning that many different areas of the brain are involved at the same time. It includes motor, visual, auditory, audiovisual, somatosensory, parietal and frontal areas in both hemispheres and the cerebellum - making music reading truly a whole brain activity. With training, the neural network strengthens. Even reading a single pitch activates this widespread network in musicians. The article also reiterates a pattern that researchers are finding: while text and music reading share some networks, they are largely independent. The pattern of activation for reading musical symbols and letters is different across the brain. Scientists have determined this via studies of patients with limited brain damage, as brain injury impaired reading of one coding system but spared the other.

Is Facebook Making Us Lonely? - 0 views

  •  
    Social media-from Facebook to Twitter-have made us more densely networked than ever. Yet for all this connectivity, new research suggests that we have never been lonelier (or more narcissistic)-and that this loneliness is making us mentally and physically ill. Social interaction matters. Loneliness and being alone are not the same thing, but both are on the rise. We meet fewer people. We gather less. And when we gather, our bonds are less meaningful and less easy. The decrease in confidants-that is, in quality social connections-has been dramatic over the past 25 years. In one survey, the mean size of networks of personal confidants decreased from 2.94 people in 1985 to 2.08 in 2004. Similarly, in 1985, only 10 percent of Americans said they had no one with whom to discuss important matters, and 15 percent said they had only one such good friend. By 2004, 25 percent had nobody to talk to, and 20 percent had only one confidant.

Want to influence the world? Map reveals the best languages to speak - 0 views

  •  
    Ronen and co-authors from MIT, Harvard University, Northeastern University, and Aix-Marseille University created worldwide maps of how multilingual people transmit information and ideas. These maps depict three global language networks based on bilingual tweeters, book translations, and multilingual Wikipedia edits. The networks potentially offer guidance to governments and other language communities that want to change their international role. "If I want my national language to be more prominent, then I should invest in translating more documents, encouraging more people to tweet in their national language," Ronen says. "On the other side, if I want our ideas to spread, we should pick a second language that's very well connected."

Keywords hold our vocabulary together in memory - 0 views

  •  
    In a study published in the Journal of Memory and Language, Michael Vitevitch, KU professor of psychology, found there are words, like main players in a social network, that hold key positions on the word network and that we process them more quickly and accurately than similar words that they hold together in our memory." The finding may help lead to new insights into developmental and acquired language disorders and treatments for those ailments.

Who Spewed That Abuse? Anonymous Yik Yak App Isn't Telling - 1 views

  •  
    Like Facebook or Twitter, Yik Yak is a social media network, only without user profiles. It does not sort messages according to friends or followers but by geographic location or, in many cases, by university. Only posts within a 1.5-mile radius appear, making Yik Yak well suited to college campuses. Think of it as a virtual community bulletin board - or maybe a virtual bathroom wall at the student union. It has become the go-to social feed for college students across the country to commiserate about finals, to find a party or to crack a joke about a rival school. Much of the chatter is harmless. Some of it is not. "Yik Yak is the Wild West of anonymous social apps," said Danielle Keats Citron, a law professor at University of Maryland and the author of "Hate Crimes in Cyberspace." "It is being increasingly used by young people in a really intimidating and destructive way."

Do We Understand the Tech Habits of Parents? - 0 views

  •  
    Recent research suggests older generations are actually more avid users of social networks than their younger counterparts, and that parents are more likely to be active on such networks than non-parents. There is evidence that these digital experiences can have negative effects. Frequent social media use is also a risk factor-one of many, of course-for depression. Sarah Coyne, a psychologist at Brigham Young University, found that new mothers often compared themselves with other mothers on social media, and that this behavior was in turn associated with "higher levels of maternal depression." Annual surveys conducted by The Center for the Digital Future at USC Annenberg show that, since 2012, people feel increasingly ignored by others in their own family households because of smartphone use.
