This article talks about a study that was conducted by MIT linguistics professors and a group from Carleton University that explored the phenomenon of why children mix up the words "and" and "or." Linguists say that children use almost entirely the same approach as adults when it comes to evaluating potentially ambiguous sentences, by testing and "strengthening" them into sentences with more precise meanings, when disjunction and conjunction ("or" and "and") are involved. However, they found that children do not test how a sentence would change if "and" was directly substituted for "or." On the other hand, adults compute "scalar implicatures," which is a technical phrase for thinking about the implications of the logical relationship between a sentence and its alternative. The research team conducted the study's experiment by testing 59 English-speaking children and 26 adults. The children ranged in age from 4 months to 6 years. The linguists gave the subjects a series of statements along with pictures, and asked them to say whether the statements were true or false. The results suggest that children are computing scalar implicatures when they evaluate the statements, but they largely do not substitute disjunctions and conjunctions when testing out the possible meaning of sentences, as adults do. In general, the researchers observed, across languages, and for children and adults alike, when you take 'and' out of the space of alternatives, "or" becomes "and."

The human voice appears to trigger pleasure circuits in the brains of typical kids, but not children with autism, a Stanford University team reports. The finding could explain why many children with autism seem indifferent to spoken words. The Stanford team used functional MRI to compare the brains of 20 children who had autism spectrum disorders and 19 typical kids. In typical kids there was a strong connection between areas that respond to the human voice and areas that release the feel-good chemical dopamine, but that connection was reduced in autistic children. Connections between voice areas and areas involved in emotion-related learning also were weaker, creating greater communication difficulties. The new study's suggestion that motivation is the problem could explain why speech often comes late to children with autism even though the brain circuit involved in processing spoken words seems to function normally; the reward circuitry isn't working the way it does in typical children.

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

"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."

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."

This article talks about the disadvantage low-income children face in regards to language acquisition. Studies show that children living in low-income areas in comparison to children from a higher-income area have an inferior knowledge of language and it sets them up for the same result when they're grown. This is because the level language they hear at home is subpar and when they go to school, the schools also lack the teaching for them to receive an adequate education. They're stuck in a paradox of growing up with insufficient schooling, then unable to advance to greater educational experiences because of it.

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 emotional bon

"We asked all the children if a certain illogical sentence was grammatically correct: "Apples grow on noses." The monolingual children couldn't answer. They'd say, "That's silly" and they'd stall. But the bilingual children would say, in their own words, "It's silly, but it's grammatically correct." The bilinguals, we found, manifested a cognitive system with the ability to attend to important information and ignore the less important."

Researchers from Brown University and King's College London have uncovered new details about how brain anatomy influences language development in young kids. Using advanced MRI, they find that different parts of the brain appear to be important for language development at different ages. Their study, published in the Journal of Neuroscience, found that the explosion of language acquisition that typically occurs in children between 2 and 4 years old is not reflected in substantial changes in brain asymmetry. Structures that support language ability tend to be localized on the left side of the brain. For that reason, the researchers expected to see more myelin -- the fatty material that insulates nerve fibers and helps electrical signals zip around the brain -- developing on the left side in children entering the critical period of language acquisition. Surprisingly, anatomy did not predict language very well between the ages of 2 and 4, when language ability increases quickly. "What we actually saw was that the asymmetry of myelin was there right from the beginning, even in the youngest children in the study, around the age of 1," said the study's lead author, Jonathan O'Muircheartaigh, the Sir Henry Wellcome Postdoctoral Fellow at King's College London. "Rather than increasing, those asymmetries remained pretty constant over time." That finding, the researchers say, underscores the importance of environment during this critical period for language. While asymmetry in myelin remained constant over time, the relationship between specific asymmetries and language ability did change, the study found. To investigate that relationship, the researchers compared the brain scans to a battery of language tests given to each child in the study. The comparison showed that asymmetries in different parts of the brain appear to predict language ability at different ages. "Regions of the brain that weren't important to successful language in toddlers became more important i

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.

A new studysuggests that children who speak multiple languages are better at understanding other people. And not only those who are fluent, but those who are simply exposed to another language in their daily lives.

"Two vital parts of mentally organizing the world are classification, or the understanding that similar things belong in the same category; and induction, an educated guess about a thing's properties if it's in a certain category. ... 'For the last 30 to 40 years it has been believed that even for very young children, labels are category markers, as they are for adults,' explains psychologist Vladimir M. Sloutsky ... To test their hypothesis, the psychologists showed pictures of two imaginary creatures to preschoolers and college undergraduates. Both animals had a body, hands, feet, antennae, and a head. ... The difference arose when the head was a jalet's but [the] label was "flurp," or vice-versa. Then, most of the adults went with the label (we accept that a dolphin is a mammal, even though it looks and swims like a fish). The children relied on the head for identification. Regardless of its name, a thing with a jalet's head is a jalet." Link to the study (PDF): http://cogdev.cog.ohio-state.edu/Papers/2011/SD-VS-PsychScience.pdf

"School-age children whose mothers nurtured them early in life have brains with a larger hippocampus ... For the current study, the researchers conducted brain scans on 92 of the children who had had symptoms of depression or were mentally healthy when they were studied as preschoolers. The imaging revealed that children without depression who had been nurtured had a hippocampus almost 10 percent larger than children whose mothers were not as nurturing. ... Although 95 percent of the parents whose nurturing skills were evaluated during the earlier study were biological mothers, the researchers say that the effects of nurturing on the brain are likely to be the same for any primary caregiver - whether they are fathers, grandparents or adoptive parents."

The impacts of music in the educational aspect of young children are profound.

A new study conducted by the University of Pennsylvania has shown that children as young as two understand basic grammar rules when they first learn to speak and are not simply imitating adults. The study also applied the same statistical analysis on data from one of the most famous animal language-acquisition experiments -- Project Nim -- and showed that Nim Chimpsky, a chimpanzee who was taught sign language over the course of many years, never grasped rules like those in a two-year-old's grammar. "When you compare what children should say if they follow grammar against what children do say, you find it to almost indistinguishable," Professor of Linguistics Charles Yang said. "If you simulate the expected diversity when a child is only repeating what adults say, it produces a diversity much lower than what children actually say." As a comparison, Yang applied the same predictive models to the set of Nim Chimpsky's signed phrases, the only data set of spontaneous animal language usage publicly available. He found further evidence for what many scientists, including Nim's own trainers, have contended about Nim: that the sequences of signs Nim put together did not follow from rules like those in human language. Nim's signs show significantly lower diversity than what is expected under a systematic grammar and were similar to the level expected with memorization. This suggests that true language learning is -- so far -- a uniquely human trait, and that it is present very early in development.

Students in South Africa are thought to be at a disadvantage since they switch from learning in their native language to learning in english. Researchers, however, believe that it is more advantageous to students to learn in the language in which they feel most comfortable. Switching between the mother tongue at home and English at school is shown to be a struggle for most children. Since the simplicity of the mother tongue has no ties to english, the children are basically learning two different languages at once, trying to apply the two to one another.

Research has proved repeatedly that children undoubtedly achieve much better when they start schooling in a language linked to one they can already use quite well. Using a familiar language for schooling is a big part of such success, which is why the late South African educationalist Neville Alexander advocated for mother tongue based-bilingual education.

Study shows that children taught words then tested on the next day score better than those tested the same day Nothing beats a good night's sleep for helping youngsters learn new words, new research has revealed. A study suggests that even the brightest children remember words best when they're given a chance to sleep on it.

In a group of internationally adopted children with cleft lip and/or palate, speech at age five is impaired compared to a corresponding group of children born in Sweden, a study shows. The adopted children also need more extensive surgery, which may be due to their surgical interventions taking place later in life.

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.
