More Screen Time Means Less Parent-Child Talk, Study Finds - 0 views

  •  
    A new longitudinal study, led by Mary E. Brushe, a researcher at the Telethon Kids Institute at the University of Western Australia, gathered data from 220 families across South Australia, Western Australia and Queensland with children who were born in 2017. Once every six months until they turned 3, the children wore T-shirts or vests that held small digital language processors that automatically tracked their exposure to certain types of electronic noise, as well as language spoken by the child, the parent or another adult. The researchers were particularly interested in three measures of language: words spoken by an adult, child vocalizations and turns in the conversation. They modeled each measure separately and adjusted the results for age, sex and other factors, such as the mother's education level and the number of children at home. Researchers found that at almost all ages, increased screen time squelched conversation. When the children were 18 months old, each additional minute of screen time was associated with 1.3 fewer child vocalizations, for example, and when they were 2 years old, an additional minute was associated with 0.4 fewer turns in conversation. The strongest negative associations emerged when the children were 3 years old - and were exposed to an average of 2 hours 52 minutes of screen time daily. At this age, just one additional minute of screen time was associated with 6.6 fewer adult words, 4.9 fewer child vocalizations and 1.1 fewer turns in conversation.

Raising a Truly Bilingual Child - The New York Times - 1 views

    The key takeaways: 1. Ensuring rich, socially-contextualized language exposure in both languages. Pediatricians advise non-English-speaking parents to read aloud and sing and tell stories and speak with their children in their native languages, so the children get that rich and complex language exposure, along with sophisticated content and information, rather than the more limited exposure you get from someone speaking a language in which the speaker is not entirely comfortable. 2. Exposure has to be person-to-person; screen time doesn't count for learning language in young children - even one language - though kids can learn content and vocabulary from educational screen time later on. 3. It does take longer to acquire two languages than one, says Dr. Erika Hoff, a developmental psychologist who specializes in early language development. "A child who is learning two languages will have a smaller vocabulary in each than a child who is only learning one; there are only so many hours in the day, and you're either hearing English or Spanish," Dr. Hoff said. The children will be fine, though, she said. They may mix the languages, but that doesn't indicate confusion. "Adult bilinguals mix their languages all the time; it's a sign of language ability," she said. 4. If exposed to the target languages at a younger age, children generally will sound more nativelike. On the other hand, older children may learn more easily. Gigliana Melzi, a developmental psychologist and associate professor of applied psychology, states, "The younger you are, the more head start you have," she said. "The older you are, the more efficient learner you are, you have a first language you can use as a bootstrap."

Letting a baby play on an iPad might lead to speech delays, study says - 0 views

  •  
    A new study, conducted by Dr. Catherine Birken, a pediatrician and scientist at the Hospital for Sick Children in Toronto, Ontario, revealed the following: the more time children between the ages of six months and two years spent using handheld screens such as smartphones, tablets and electronic games, the more likely they were to experience speech delays. In the study, which involved nearly 900 children, parents reported the amount of time their children spent using screens in minutes per day at age 18 months. Researchers then used an infant toddler checklist, a validated screening tool, to assess the children's language development also at 18 months. They looked at a range of things, including whether the child uses sounds or words to get attention or help and puts words together, and how many words the child uses. Twenty percent of the children spent an average of 28 minutes a day using screens, the study found. Every 30-minute increase in daily screen time was linked to a 49% increased risk of what the researchers call expressive speech delay, which is using sounds and words. Commenting on the study, Michelle MacRoy-Higgins and Carlyn Kolker, both speech pathologists/therapists and co-authors of "Time to Talk: What You Need to Know About Your Child's Speech and Language Development," offered this advice: interact with your child. The best way to teach them language is by interacting with them, talking with them, playing with them, using different vocabulary, pointing things out to them and telling them stories.

    "Researchers showed children images and voices of a child and two adults, and asked, "Which adult will the child grow up to be?" Children were presented with a challenge: One adult matched the child's race, and one matched the child's language, but neither matched both. ... As would be expected, 9- and 10-year-old children chose the adult who matched the featured child's race. ... Five- and six-year-old English-speaking white children's responses were a bit more surprising: Most of those children chose the language match, even though this meant that the featured child would have needed to change race."

Babbling Babies - responding to one-on-one 'baby talk' helps master more words - 1 views

  •  
    Researchers at the University of Washington and University of Connecticut examined thousands of 30-second snippets of verbal exchanges between parents and babies. They measured parents' use of a regular speaking voice versus an exaggerated, animated baby talk style, and whether speech occurred one-on-one between parent and child or in group settings. "What our analysis shows is that the prevalence of baby talk in one-on-one conversations with children is linked to better language development, both concurrent and future," said Patricia Kuhl, co-author and co-director of UW's Institute for Learning & Brain Sciences. The more parents exaggerated vowels -- for example "How are youuuuu?" -- and raised the pitch of their voices, the more the 1-year olds babbled, which is a forerunner of word production. Baby talk was most effective when a parent spoke with a child individually, without other adults or children around. "The fact that the infant's babbling itself plays a role in future language development shows how important the interchange between parent and child is," Kuhl said.

In the beginning was the word: How babbling to babies can boost their brains - 2 views

    The more parents talk to their children, the faster those children's vocabularies grow and the better their intelligence develops. The problem seems to be cumulative. By the time children are two, there is a six-month disparity in the language-processing skills and vocabulary of toddlers from low-income families. Toddlers learn new words from their context, so the faster a child understands the words he already knows, the easier it is for him to attend to those he does not. Dr Anne Fernald, of Stanford, found that words spoken directly to a child, rather than those simply heard in the home, are what builds vocabulary. Plonking children in front of the television does not have the same effect. Neither does letting them sit at the feet of academic parents while the grown-ups converse about Plato. The effects can be seen directly in the brain. Kimberly Noble of Columbia University studies how linguistic disparities are reflected in the structure of the parts of the brain involved in processing language. Although she cannot yet prove that hearing speech causes the brain to grow, it would fit with existing theories of how experience shapes the brain. Babies are born with about 100 billion neurons, and connections between these form at an exponentially rising rate in the first years of life. It is the pattern of these connections which determines how well the brain works, and what it learns. By the time a child is three, there will be about 1,000 trillion connections in his brain, and that child's experiences continuously determine which are strengthened and which pruned. This process, gradual and more-or-less irreversible, shapes the trajectory of the child's life.And it is this gap, more than a year's pre-schooling at the age of four, which seems to determine a child's chances for the rest of his life.

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.

  •  
    The LENA System measures the early language environment of children birth to 48 months. It consists of a compact digital recorder with clothing so a child can wear it comfortably; software that turns the recording into data; and a cloud-based system for managing the data. Feedback from LENA helps parents and caregivers increase the quantity and quality of interactive talk. While words are important, "conversational turns" are even more so - times when an adult says something and the child responds, or vice versa. Turns measure interactions, and according to research, they're a very powerful predictor of brain growth. LENA devices were mentioned in "In the Beginning Was the Word" article from _The Economist_.

Bilingual babies: Study shows how exposure to a foreign language ignites infants' learn... - 0 views

  •  
    Researchers at the University of Washington developed a play-based, intensive, English-language method and curriculum and implemented the research-based program in four public infant-education centers in Madrid, Spain. Based on years of UW's I-LABS (Institute of Learning and Brain Science) research on infant brain and language development, UW's pilot bilingual education method utilized the following brain-research principles: 1. social interaction 2. play 3. high quality and quantity of language from the teachers. 4. Use of "infant-directed speech", or "parentese": the speech style parents use to talk to their babies, which has simpler grammar, higher and exaggerated pitch, and drawn-out vowels. 5. Active child engagement. The country's extensive public education system enabled the researchers to enroll 280 infants and children from families of varying income levels. Babies aged 7 to 33.5 months were given one hour of English sessions a day, using the UW method, for 18 weeks, while a control group received the Madrid schools' standard bilingual program. Both groups of children were tested in Spanish and English at the start and end of the 18 weeks. Children who received the UW method showed rapid increases in English comprehension and production, and significantly outperformed the control group peers at all ages on all tests of English. By the end of the 18-week program, the children in the UW program produced an average of 74 English words or phrases per child, per hour; children in the control group produced 13 English words or phrases per child, per hour.

Bedtime Stories for Young Brains - 3 views

  •  
    This month, the journal Pediatrics published a study that used functional magnetic resonance imaging to study brain activity in 3-to 5-year-old children as they listened to age-appropriate stories. The researchers found differences in brain activation according to how much the children had been read to at home. Children whose parents reported more reading at home and more books in the home showed significantly greater activation of brain areas in a region of the left hemisphere called the parietal-temporal-occipital association cortex. This brain area is "a watershed region, all about multisensory integration, integrating sound and then visual stimulation," said the lead author, Dr. John S. Hutton, a clinical research fellow at Cincinnati Children's Hospital Medical Center. This region of the brain is known to be very active when older children read to themselves, but Dr. Hutton notes that it also lights up when younger children are hearing stories. What was especially novel was that children who were exposed to more books and home reading showed significantly more activity in the areas of the brain that process visual association, even though the child was in the scanner just listening to a story and could not see any pictures. "When kids are hearing stories, they're imagining in their mind's eye when they hear the story," said Dr. Hutton. "For example, 'The frog jumped over the log.' I've seen a frog before, I've seen a log before, what does that look like?" The different levels of brain activation, he said, suggest that children who have more practice in developing those visual images, as they look at picture books and listen to stories, may develop skills that will help them make images and stories out of words later on. "It helps them understand what things look like, and may help them transition to books without pictures," he said. "It will help them later be better readers because they've developed that part of the brain

What\'s Behind A Temper Tantrum? Scientists Deconstruct The Screams : NPR - 1 views

    "...scientists found that different toddler sounds - or "vocalizations" - emerge and fade in a definite rhythm in the course of a tantrum. "We have the most quantitative theory of tantrums that has ever been developed in the history of humankind" ... where one age-old theory of tantrums might suggest that meltdowns begin in anger (yells and screams) and end in sadness (cries and whimpers), Potegal found that the two emotions were more deeply intertwined. ... The trick in getting a tantrum to end as soon as possible, Potegal said, was to get the child past the peaks of anger. Once the child was past being angry, what was left was sadness, and sad children reach out for comfort. The quickest way past the anger, the scientists said, was to do nothing."

How similar are the gestures of apes and human infants? More than you might suspect - 2 views

  •  
    Psychologists who analyzed video footage of a female chimpanzee, a female bonobo and a female human infant in a study to compare different types of gestures at comparable stages of communicative development found remarkable similarities among the three species. Gestures made by all three species included reaching, pointing with fingers or the head, and raising the arms to ask to be picked up. The researchers called "striking" the finding that the gestures of all three species were "predominantly communicative," Greenfield said. To be classified as communicative, a gesture had to include eye contact with the conversational partner, be accompanied by vocalization (non-speech sounds) or include a visible behavioral effort to elicit a response. The same standard was used for all three species. For all three, gestures were usually accompanied by one or more behavioral signs of an intention to communicate. At the beginning stage of communication development, gesture was the primary mode of communication for human infant, baby chimpanzee and baby bonobo. The child progressed much more rapidly in the development of symbols. Words began to dominate her communication in the second half of the study, while the two apes continued to rely predominantly on gesture. "This was the first indication of a distinctive human pathway to language," Greenfield said. All three species increased their use of symbols, as opposed to gestures, as they grew older, but this change was far more pronounced for the human child. The child's transition from gesture to symbol could be a developmental model of the evolutionary pathway to human language and thus evidence for the "gestural origins of human language," Greenfield said. While gesture may be the first step in language evolution, the psychologists also found evidence that the evolutionary pathway from gesture to human language included the "co-evolution of gestural and vocal communication." Most of the child's gestures were accompanied b
